winners and losers in housing markets this paper is a quantitatively oriented theoretical study into the interaction between housing prices aggregate production and household behaviour over a lifetime we develop a life cycle model of a production economy in which land and capital are used to build residential and commercial structures we find that in an economy where the share of land in the value of structures is large housing prices react more to an exogenous change in expected productivity or the world interest rate causing large redistribution effects between net buyers and net sellers of houses changing the financing constraint however has limited effects on housing prices

innovation enterprise as a vehicle for sustainable development a general framework for the design of typical strategies based on enterprise systems engineering dynamic capabilities and option thinking abstract the development of strategies actions and programs on sustainability through innovation has been taking into account within the current essential and disorderly train of events the issue of designing mechanisms was considered by institutions and organizations which innovate on sustainability the way of speeding the progress as well as the process of learning on sustainability there has been always a concern over forwarding the incremental innovations which actually improve or renew the already existing ideas and practices at the level of system or even the sos systems level together with a new focus over the technical social human and environment or markets interspaces the main issue regards the type of changes necessary on transforming the sustainability new institutions public politics strategies of settlements new ways of thinking and business practices the analysis of innovative part within the process of economic and social change should gather interdisciplinary multidisciplinary and trans disciplinary research although there is an obvious agenda of integrating the sustainability within the process of innovation the long term approach has not been provided with a phasing and the process has been quite complex the current global process has been characterized by a socio technological dynamism of an accurate changing management more exactly by the oscillation between intervals of normality and steadiness and disorderly and volatile intervals that influence the design way of strategies since these should understand and integrate the new dynamics of change of markets and of the external environment the traditional approach cannot show such mixtures of dynamics and cut off over the markets and stakeholders this paper emphasizes the synergic assortment between the systematic control of innovation for sustainable development focused on the internal environment and that based on a mix between the concept of innovation enterprise in context of enterprise systems engineering the dynamic capabilities for spectral selection in a multiple dynamics and option thinking as a paradigm well adapted in innovation the dynamic capabilities seen as strategy of creating the strategies have offered a quick qualitative image so that this approach has been combined with the paradigm of real options within a frame that proposes the active control over the extended performance of innovation enterprise the novelty has been offered by the possibility of emphasizing some mechanism of inter correlations between innovation enterprise the dynamic capabilities as strategic tool of high level and the real options as tool of option thinking on one hand and the capabilities for innovation on extended way on the other hand adapting the paradigm of dynamic capabilities to the oscillation between the normality or steadiness times and those full of disorder and volatility by means of real composed options has offered a dynamic image of relative performance during a complex process viewing the performances progress in two steps and two volatilities has been quite significant since it offered the possibility of some immediate actions of reconfigurations and conformation to

capital income taxation with housing abstract this paper quantitatively investigates capital income taxation in the general equilibrium overlapping generations model with household heterogeneity and housing housing tax policy is found to affect how capital income should be taxed due to substitution between housing and non housing capital given the existing u s preferential tax treatment for owner occupied housing the optimal capital income tax rate is close to zero 1 contrary to the high optimal capital income tax rate found with overlapping generations models without housing 31 a low capital income tax rate improves welfare by narrowing a tax wedge between housing and non housing capital the narrowed tax wedge indirectly nullifies the subsidies taxes for homeowners renters and corrects over investment to housing naturally when the preferential tax treatment for owner occupied housing is eliminated a high capital income tax rate improves welfare as in the model without housing

banking in computable general equilibrium economies abstract in this paper we develop a computable general equilibrium economy that models the banking sector explicitly banks intermediate between households and between the household sector and the government sector households borrow from banks to finance their purchases of houses and they lend to banks to save for retirement banks pool households savings and they purchase interest bearing government debt and non interest bearing reserves we use this structure to answer two sets of questions one normative in nature that evaluates the welfare costs of alternative monetary and tax policies and one positive in nature that studies the real effects of following a procyclical interest rate policy rule

budget constraints and time series evidence on consumption is consumption more or less variable than predicted by the permanent income hypothesis pih to answer that question i develop a procedure based on a long run restriction implied by the consumer s intertemporal budget constraint in contrast to previous work the approach here i does not require any assumptions on the stochastic properties of labor income ii does not impose restrictions on the consumer s information set and iii is robust to departures from the pih model the application of the procedure to postwar u s data suggests that consumption is smoother than the pih model predicts jel 131

credit constraints house prices and the impact of life cycle dynamics abstract how does the life cycle impact house price dynamics this paper investigates how equilibrium house prices respond to a tightening in credit constraints under two different but similarly calibrated models one an infinite horizon setting and the other a life cycle environment the main conclusion is that house price dynamics are magnified by the presence of life cycle features two primary explanations stand out the distinction between stocks and flows of mortgage debt in the cross section and the importance of gross housing tenure flows i e churn

how sustainable entrepreneurs engage in institutional change insights from biomass torrefaction in the netherlands sustainable entrepreneurship often requires a purposeful change to the existing business environment market regulations and societal norms and values institutions to ensure sustainable products and services become legitimate and competitive yet how sustainable entrepreneurs alter or create institutions remains unclear we employ a two year comparative case study with four entrepreneurs commercializing torrefied biomass in the netherlands consistent with insights from institutional entrepreneurship research findings show that sustainable entrepreneurs create new symbols theorize construct new measures build consensus and forge new relations to alter or create new institutions moreover we find that entrepreneurial collaboration in the form of a trade association has three feedback effects it creates accessible modes diversity of scope and an increased scale of institutional change strategies we conclude that future studies should further connect sustainable and institutional entrepreneurship research and take group and individual factors into account when explaining how sustainable entrepreneurs engage in institutional change

daily house price indexes construction modeling and longer run predictions we construct daily house price indexes for ten major u s metropolitan areas our calculations are based on a comprehensive database of several million residential property transactions and a standard repeat sales method that closely mimics the procedure used in the construction of the popular monthly case shiller house price indexes our new daily house price indexes exhibit similar characteristics to other daily asset prices with mild autocorrelation and strong conditional heteroskedasticity which are well described by a relatively simple multivariate garch type model the sample and model implied correlations across house price index returns are low at the daily frequency but rise monotonically with the return horizon and are all commensurate with existing empirical evidence for the existing monthly and quarterly house price series a simple model of daily house price index returns produces forecasts of monthly house price changes that are superior to various alternative forecast procedures based on lower frequency data underscoring the informational advantages of our new more finely sampled daily price series

wealth distribution in life cycle economies abstract this paper compares the age wealth distribution produced in life cycle economies to the corresponding distribution in the us economy the idea is to calibrate the model economies to match features of the us earnings distribution and then examine the wealth distribution implications of the model economies the findings are that the calibrated model economies with earnings and lifetime uncertainty can replicate measures of both aggregate wealth and transfer wealth in the us furthermore the model economies produce the us wealth gini and a significant fraction of the wealth inequality within age groups however the model economies produce less than half the fraction of wealth held by the top 1 percent of us households

internal drivers and performance consequences of small firm green business strategy the moderating role of external forces growing detrimental effects on the bio physical environment have been responsible for a large number of small firms to adopt a more strategic stance toward exploiting green related opportunities this article aims to shed light on how internal company factors help to formulate a green business strategy among small manufacturing firms and how this in turn influences their competitive advantage and performance based on data received from 153 small cypriot manufacturers we propose and test a conceptual model anchored on the resource based view of the firm the findings underscore the critical role of both organizational resources and capabilities in pursuing a green business strategy the adoption of this strategy was more evident in the case of firms operating in more harmful as opposed to less harmful industries the implementation of a green business strategy was found to generate a positional competitive advantage with this association becoming stronger under conditions of high regulatory intensity high market dynamism high public concern and high competitive intensity it was also revealed that this competitive advantage is conducive to gaining heightened market and financial performance our study makes a fivefold contribution it injects a theoretical perspective into a relatively atheoretic field underlines the role of organizational resources capabilities as drivers of eco friendly initiatives highlights the often neglected strategic aspects of small firms ecological business activities stresses the contingent role of external forces in moderating the positive impact of small firm green business strategy on competitive advantage and focuses on the performance implications of the small firm s engagement in environmental operations

home equity in retirement retired homeowners dissave more slowly than renters which suggests that homeownership affects retirees saving decisions we investigate empirically and theoretically the life cycle patterns of homeownership housing and nonhousing assets in retirement using an estimated structural model of saving and housing decisions we find first that homeowners dissave slowly because they prefer to stay in their house as long as possible but cannot easily borrow against it second the 1996 2006 housing boom significantly increased homeowners assets these channels are quantitatively significant without considering homeownership retirees net worth would be 28 44 lower depending on age

erratum to how far the tbl concept of sustainable entrepreneurship extends beyond the various sustainability regulations can greek food manufacturing enterprises sustain their hybrid nature over time this study presents the design and selected results of a comprehensive research on measuring the concept of sustainable entrepreneurship we used the methodology of conjoint analysis and developed a hierarchical framework that lists all the multi attributes that exist in the triple bottom line concept in doing so we collected data from 150 greek food companies the multi attributes were categorized and ranked into the following four headings internal social values isv external social values esv environmental values env and economic values ecv specifically we found that the creation of values that improve the safety and hygiene issues of products to consumers is the most important attribute for the isv domain respectively the most important attribute for the esv domain is the creation of values that impact on the local economy accordingly the creation of values for minimizing environmental impacts was found as the most important attribute for the env domain and lastly the establishment of ecv that increase long run profitability was identified as the most important for the ecv dimension finally all the categorized values offer rich feedback for entrepreneurship scholars and parishioners and to that extent our findings are slightly different from those reported in previous researches to other contexts as we have managed to build an aggregated instrument that promotes the hybrid nature of food companies towards international development

snap benefits and crime evidence from changing disbursement schedules in this paper we study the effects of the timing of nutritional aid disbursement on crime using two main sources of variation a a policy change in illinois that substantially increased the num

the wealth distribution with durable goods in the united states the distribution of houses is less egalitarian than that of earnings for the total population but these two distributions are remarkably similar for homeowners additionally housing as a fraction of total wealth decreases with the level of wealth in order to understand the different factors that account for these wealth composition patterns we introduce illiquid houses and collateral credit in a general equilibrium model of heterogeneous agents with idiosyncratic uncertainty a combination of very persistent shocks to earnings frictions in the housing market and a rental market is necessary to obtain numbers in line with the evidence

financial intermediation house prices and the welfare effects of the u s great recession abstract this paper quantifies the welfare costs of the great recession in the united states and their distribution between borrowing and saving households we use a calibrated dynamic general equilibrium model with shocks to aggregate income and to the financial intermediation sector the model matches the boom bust cycle in house prices the dynamics of household leverage and the increase in inequality of wealth observed in the u s after 2007 we find large welfare costs for financially constrained households the borrowers savers instead benefited from a redistribution of housing wealth due to the de leveraging of borrowers caused by the plunge in house prices this redistribution mechanism was exacerbated by the financial intermediation shock we also show that the welfare costs for borrowers would have been lower if aggregate leverage had remained at pre 2001 levels

housing demand during the boom the role of expectations and credit constraints i use a life cycle model of housing demand to infer expectations about house prices and home equity requirements for the housing boom of the 2000s from observed household choices expectations and credit constraints are separately identified from the intensive and extensive margins of housing demand the main results are that 1 expected price growth was close to average long run growth 2 home equity requirements were lax initially but tightened after the bust and 3 subjective uncertainty about future price growth was large given the option to default on mortgage debt greater price uncertainty leads to higher optimal household leverage

capital goods measured tfp and growth the case of spain the effect of investing in equipment and or structures on tfp and long run growth is investigated here we argue that economies can grow in spite of stagnant tfp if the investment rate is inefficiently high we study the case of spain where real gdp per worker grew at 2 74 percent annually and tfp was stagnant during 1996 2007 we show that low spanish tfp is due to low istc and an inefficiently high investment in residential structures we quantify the effect of the housing boom of the 2000s the total cost of subsidies to residential structures in terms of tfp and income growth

consumer durables and inertial behaviour estimation and aggregation of s s rules for automobile purchases the s s model originally introduced in the study of inventories see arrow et al 1951 scarf 1959 has recently received renewed attention both in the durable consumption and in the investment and labour demand literatures caballero 1993 for instance appeals to these type of models to explain the time series properties of durable expenditure and in particular the persistence or slow adjustment of such a variable in this paper i model the purchase behaviour of automobiles by u s households as an s s rule i estimate a flexible specification of such a rule using a large microeconomic data set and study some of the aggregate implications of this type of inertial behaviour the paper is one of the first attempts at estimating directly the parameters of an s s rule using micro data because of this some of the methodological issues concerning the specification and the estimation of s s rules are relevant for many potential applications furthermore the paper is one of the first to discuss and quantify the aggregate implications of an s s rule estimated on micro data in the presence of non convex transaction costs a full and consistent characterization of individual behaviour is very hard and typically requires strong restrictions grossman and laroque 1991 prove that an s s rule is optimal for a consumption and investment problem under very special circumstances some of their results were extended by eberly 1991 and beaulieu 1993a b eberly 1991 in particular has derived some closed form solutions for durable consumption in the presence of transaction costs while caballero and engel 1994 construct a model of investment where an s s rule is optimal the main problem with these theoretical results is that it is only possible to show optimality of s s rules under very stringent conditions in particular a necessary condition to derive them is that the optimization problem faced by an individual consumer can be reduced to a problem with a single state variable unfortunately as pointed out by bar ilan and blinder 1992 even simple generalizations are extremely difficult to analyse

household production and the excess sensitivity of consumption to current income empirical research on the permanent income hypothesis pih has found that consumption growth is excessively sensitive to predictable changes in income this finding is interpreted as strong evidence against the pih we propose an explanation for apparent excess sensitivity that is based on a quantitative equilibrium model of household production in which permanent income consumers respond to shifts in sectoral wages and prices by substituting work effort and consumption across home and market sectors although the pih is true this mechanism generates apparent excess sensitivity because market consumption responds to predictable income growth

the method of endogenous gridpoints with occasionally binding constraints among endogenous variables we show how the method of endogenous gridpoints can be extended to solve models with occasionally binding constraints among endogenous variables very efficiently we present the method for a consumer problem with occasionally binding collateral constraints and non separable utility in durable and non durable consumption this problem allows for a joint analysis of durable and non durable consumption in models with uninsurable income risk which is important to understand patterns of consumption saving and collateralized debt we illustrate the algorithm and its efficiency by calibrating the model to us data

how do consumers avoid penalty fees evidence from credit cards using data from multiple card issuers we show that the most common penalty fee type incurred by credit card holders late payment fees declines sharply over the first few months of card life thi

irreversibility and consumer durables expenditures abstract this paper examines the implications of resale market imperfection on consumer durables expenditures the consumer optimization problem under resale market imperfection is formulated and solved numerically by dynamic programming algorithm the obtained decision rules of consumers reveal the slow upward and downward adjustments of durables stock the simulated aggregate durables expenditures with resale market imperfection exhibit substantial serial correlations similar to those found in actual durables expenditures time series the substantial serial correlations are found to be related to the pattern of the decision rules under resale market imperfections

durables nondurables down payments and consumption excesses abstract we examine a model that generalizes the standard buffer stock model of saving to accommodate durables nondurables down payment requirements and adjustment costs in the durables market we find that nondurable consumption becomes more volatile relative to income as down payments decrease at the individual and at the aggregate level moreover for plausible parameter values the model can explain the excess smoothness and excess sensitivity observed in u s aggregate data the result follows from a gradual adjustment of consumption to permanent income shocks when agents attempt to spread out the burden of down payments over time compounded by slow adjustment due to transaction costs

designing a global standardized methodology for measuring social entrepreneurship activity the global entrepreneurship monitor social entrepreneurship study although there is a high level of practitioner policymaker and scholar interest in social entrepreneurship most research is based on case studies and success stories of successful social entrepreneurs in a single country we develop a methodology to measure population based social entrepreneurship activity sea prevalence rates and test it in 49 countries our results provide insights into institutional and individual drivers of sea using the global entrepreneurship monitor gem methodology of total entrepreneurial activity tea we find that countries with higher rates of traditional entrepreneurial activity also tend to have higher rates of social entrepreneurial activity we develop a broad definition of social entrepreneurship and then explore types based on social mission revenue model and innovativeness

mortgage debt consumption and illiquid housing markets in the great recession using a model with housing search endogenous credit constraints and mortgage default this paper accounts for the housing crash from 2006 to 2011 and its implications for aggregate and cross sectional consumption during the great recession left tail shocks to labor market uncertainty and tighter down payment requirements emerge as the key drivers an endogenous decline in housing liquidity amplifies the recession by increasing foreclosures contracting credit and depressing consumption balance sheets act as a transmission mechanism from housing to consumption that depends on gross portfolio positions and the leverage distribution low interest rate policies accelerate the recovery in housing and consumption

choice simplification a theory of mental budgeting and naive diversification we develop a theory of how an agent makes basic multiproduct consumption decisions in the presence of taste consumption opportunity and price shocks that are costly to attend to we establish that the agent often simplifies her choices by restricting attention to a few important considerations which depend on the decision at hand and affect her consumption patterns in specific ways if the agent s problem is to choose the consumption levels of many goods with different degrees of substitutability then she may create mental budgets for more substitutable products e g entertainment in some situations it is optimal to specify budgets in terms of consumption quantities but when most products have an abundance of substitutes specifying budgets in terms of nominal spending tends to be optimal if the goods are complements in contrast then the agent may consistent with naive diversification choose a fixed unconsidered mix of products and if the agent s problem is to choose one of multiple products to fulfill a given consumption need e g for gasoline or a bed then it is often optimal for her to allocate a fixed sum for the need

house prices and consumption inequality i characterize how house price shocks affect consumption inequality using a life cycle model of housing and nonhousing consumption with incomplete markets i derive analytical expressions for the dynamics of inequalities and use these to analyze large house prices swings seen in the uk i show that movements in consumption inequality were large that they correspond with the theoretical predictions qualitatively and that the model explains a large fraction of the movements quantitatively i demonstrate the accuracy of this analysis using an extended model s full non linear solution finally accounting for house price shocks alters estimates of labour income risks using cross sectional data

the reaction of household consumption to predictable changes in social security taxes the key implication of rational expectations and the basic life cycle permanent income hypothesis that predictable changes in income have no effect on the growth rate of consumption expenditures is examined this implication is important for understanding the effectiveness and optimal timing of fiscal policy the causes and propagation of business cycles and the effects of income fluctuations on the growth rate of the economy using household level consumption data from the consumer expenditure survey whether expenditures on nondurable goods increase contemporaneously with predictable changes in social security tax withholding is tested it is found that households do change their consumption expenditures in response to the predictable fluctuations in income induced by the social security tax system

expenditure response to increases in in kind transfers evidence from the supplemental nutrition assistance program recent studies on food stamp participant households marginal propensity to spend out of food stamps versus income have had contradictory results experimental studies have found household behavior aligns with standard economic theory where households marginal propensity to spend on food out of food stamps is equivalent to cash income observational studies nd that households have a larger marginal propensity to spend out of food stamps than cash income in this study we re examine this question by estimating how an unprecedentedly large increase in food stamp benets due to the implementation of the american recovery and reinvestment act aects food at home expenditure we nd that the policy change caused households to increase food at home expenditure as well as increase households share of total expenditure allocated toward food at home expenditure we compare these results to a time period without a meaningful food stamp policy change and nd our results are unique to the arra implementation time period

accounting for the u s earnings and wealth inequality we show that a theory of earnings and wealth inequality based on the optimal choices of ex ante identical households that face uninsured idiosyncratic shocks to their endowments of efficiency labor units accounts for the u s earnings and wealth inequality almost exactly

saving and liquidity constraints this paper is concerned with the theory of saving when consumers are not permitted to borrow and with the ability of such a theory to account for some of the stylized facts of saving behavior the models presented in the paper seem to account for important aspects of reality that are not explained by traditional life cycle models copyright 1991 by the econometric society

sustainability driven entrepreneurship principles of organization design abstract concern about whether the social ecological processes that provide for human wellbeing can be sustained has given rise to sustainable development as a broad social goal as a dynamic force for change entrepreneurship is increasingly expected to contribute to this goal this article reports on the results of an intensive empirical study investigating the organization design expertise necessary for sustainability driven entrepreneurs to succeed in a competitive market context results reveal five principles of organization design that diverge in important ways from the conventional principles of entrepreneurship suggesting the expertise required for venture success differs depending on entrepreneurial values and motives

is microcredit a blessing for the poor a meta analysis examining development outcomes and contextual considerations abstract increasing efforts aim at economic development and the reduction of poverty in developing countries through microcredit enabled entrepreneurship following the award of the nobel peace prize to prof yunus microcredit lending has risen to prominence and the volume of microcredit loans has increased substantially however theory on the outcomes of this financing form is controversial furthermore the academic community lacks conclusive empirical evidence about the impact of such programs primary empirical studies report fragmented and to a large extent contradictory results in this meta analysis we empirically synthesize a total of 545 quantitative empirical findings from 90 studies conducted to date our findings reveal a positive impact of microcredit on key development outcomes at the level of the client entrepreneurs additionally we scrutinize how the development context influences the effectiveness of microcredit and find that microcredit generally has a greater impact in more challenging contexts with our findings we contribute to research on the nexus of entrepreneurship and economic development and offer recommendations for practitioners and academics working on this promising frontier

associative sustainable business models cases in the bean to bar chocolate industry abstract this study contributes to the growing literature of sustainability business models sbm by introducing a new category coined as associative sustainability business models asbm we theorize that this category encompasses firms with innovative business models that rely on partnership association and collaboration to create value in the triple bottom line and address pressing sustainability challenges following an inductive research approach we analyze four case studies of asbm ventures in the chocolate industry our findings reveal the emergence of two key theoretical constructs firm location and claimant identity that help to identify differences across asbm designs and lead to four different subcategories of asbm in addition drawing on the literature of sustainable business models we develop theoretical propositions that link our four subcategories of asbm to the business case for sustainability therefore we extend the literature on sbm by providing new insights on how business model innovations based on strong association and collaboration can generate solutions to social and environmental challenges

intertemporal consumption durables and liquidity constraints a cohort analysis we provide a theoretical framework to analyse the response of life time maximizing consumers to intertemporal prices of non durable goods and durable goods when the borrowing limit depends on the market value of the stock of durables owned by the consumer we use pseudo panel data on purchases of non durables and durable goods cars and demographic characteristics from the uk family expenditure survey as well as estimates of the durable stock constructed using the uk national travel survey to estimate the equations derived in the first part of the paper we evaluate the shadow prices of these restrictions which were significantly positive for younger consumers in the mid seventies and immediately prior to the 1982 financial liberalisation

union contracts and the life cycle permanent income hypothesis this paper isolates households in the psid whose heads can be matched to particular long term union contracts with high confidence the author uses use published information on these contracts to construct a household specific measure of expected wage growth he finds that predictable wage movements are significantly correlated with consumption changes contrary to neoclassical consumption theory the author finds that consumption responds more strongly to predictable income declines than to predictable income increases this asymmetry is inconsistent with liquidity constraints and myopia but is qualitatively consistent with models in which preferences exhibit loss aversion copyright 1995 by american economic association

a dynamic model of housing demand estimation and policy implications in the u s macroeconomic policy makers are concerned about how consumers will respond to falling incomes nominal home prices falling income rising mortgage interest rates and tightening credit standards in order to address these questions we estimate and simulate a dynamic structural model of housing demand in the model consumers maximize expected discounted lifetime utility from housing services and a composite consumption good the model allows for realistic features of the housing market including non convex adjustment costs from buying and selling a home and credit constraints from minimum downpayment requirements we use the forward simulation procedure of bajari benkard and levin 2007 to estimate the structural parameters especially the elasticity of substitution between consumption and housing services using data from the panel study of income dynamics given the estimated model parameters we simulate the partial equilibrium consumption and housing and

distributional implications of government guarantees in mortgage markets we analyze the removal of the credit risk guarantees provided by the government sponsored enterprises gses in a model with agents heterogeneous in income and house price risk we find that wealth inequality increases driven by higher mortgage spreads and housing rents housing holdings become more concentrated foreclosures fall the removal benefits high income households while hurting low and mid income households renters and highly leveraged mortgagors with conforming loans gse reform requires compensating transfers sufficiently high elasticity of rental supply or linking gse reform with the elimination of the mortgage interest deduction

is consumption growth consistent with intertemporal optimization evidence from the consumer expenditure survey in this paper we show that some of the predictions of models of consumer intertemporal optimization are in line with the patterns of nondurable expenditure observed in u s household level data we propose a flexible specification of preferences that allows multiple commodities and yields empirically tractable equations we estimate preference parameters using the only u s micro data set with complete consumption information we show that previous rejections can be explained by the simplifying assumptions made in previous studies we also show that results obtained using good consumption or aggregate data can be misleading

market imperfections opportunity and sustainable entrepreneurship this research develops the argument that four types of market imperfections i e inefficient firms externalities flawed pricing mechanisms and information asymmetries at once contribute to environmental degradation and that they also provide significant opportunities for the creation of radical technologies and innovative business models we show that these opportunities establish the foundations for an emerging model of sustainable entrepreneurship one which enables founders to obtain entrepreneurial rents while simultaneously improving local and global social and environmental conditions to advance this new field we offer suggestions for a research agenda focusing on two areas the relationship between market imperfections and entrepreneurial opportunities and the emerging field of sustainable entrepreneurship

does buffer stock saving explain the smoothness and excess sensitivity of consumption one of the lasting contributions to modernday consumer theory is the idea that consumption is determined by the expected value of lifetime resources or permanent income the modern day specification of this concept is typically presented as a special case of intertemporalchoice theory where felicity functions are quadratic labor income is stochastic there are no restrictions on borrowing consumers have infinite horizons and expectations are formed rationally we refer to this model as the permanentincome hypothesis pih although the pih has considerable intuitive appeal a series of influential papers published after its inception revealed two notable discrepancies between the model s predictions and aggregate data first the model predicts that consumption growth should be more volatile than income growth if aggregate income growth has positive serial correlation as the quarterly data suggest it does yet aggregate consumption growth is in fact much smoother than aggregate income growth angus deaton 1987 john y campbell and deaton 1989 jordi gali 1991 second the pih predicts that consumption changes should be orthogonal to predictable or lagged income changes yet the coffelation between consumption growth and lagged income growth has been found to be one of the most robust features of aggregate data for example marjorie a flavin 1981 alan s blinder and deaton 1985 campbell and n gregory mankiw 1989 orazio p attanasio and guglielmo weber 1993 thus aggregate consumption growth has been described as exhibiting two puzzles it is both excessively smooth relative to current labor income growth and excessively sensitive to lagged labor income growth 2 in response to these and other empirical anomalies researchers have recently sought out modifications of the pih framework chief ludvigson federal reserve bank of new york 33 liberty street new york ny 10045 michaelides university of cyprus p o box 20537 1678 nicosia cyprus a previous version of this paper appeared under the title can we explain the consumption excesses yet aggregate consumption implications of buffer stock saving behavior for many helpful comments we thank orazio attanasio dave backus ben bernanke john y campbell christopher carroll todd clark angus deaton pierreolivier gourinchas bo honore james kahn martin lettau costas meghir christina paxson steve pischke andrew samwick christopher sims mark watson guglielmo weber michael woodford steve zeldes and two anonymous referees conference participants at the national bureau of economic research summer workshop on the aggregate implications of microeconomic consumption behavior july 1998 the tmr workshop on saving and pensions center tilburg university march 1999 and the new york area macroeconomics workshop october 1998 seminar participants at columbia university insead the new york federal reserve university college london london business school city university business school university of cyprus tel aviv university and jeffrey brown for excellent research assistance the views expressed are those of the authors and do not necessarily reflect those of the federal reserve bank of new york or the federal reserve system any errors or omissions are the responsibility of the authors 1 note that the important insight of danny quah 1990 that individuals may be better able than econometricians to distinguish short run from long run innovations to their income cannot resolve the excess smoothness puzzle laid out in campbell and deaton 1989 these authors show that in the context of the pih excess sensitivity and excess smoothness are the same phenomena in addition campbell 1987 demonstrates that superior information of the type emphasized by quah will show up in households saving behavior and using this information allows the econometrician to control for the agent s private information when predicting income since excess sensitivity is well established and controlling for saving does not eliminate it see campbell and deaton 1989 the observed smoothness of consumption cannot be explained by superior information on the part of permanent income consumers see deaton 1992 for further discussion 2 philippe bacchetta and stefan gerlach 1997 and ludvigson 1999 document another kind of excess sensitivity the correlation between consumption growth and predictable changes in consumer credit although we do not explore these findings here ludvigson finds that a bufferstock model with time varying liquidity constraints can replicate such a correlation

on the taxation of durable goods this paper proposes a mirrleesian theory of commodity taxation in the presence of durable goods nondurable goods should be taxed uniformly provided that the preferences over nondurable consumption are weakly separable from labor effort a uniform taxation across all goods is optimal if the utility from durable consumption is linear and the preferences are additively separable between durable goods nondurable goods and labor effort if those conditions are not met wealth effects and substitution effects justify the use of differential commodity taxes to characterize the sign of the tax differential the paper exploits a substitution euler equation that links the marginal rate of substitution between durable and nondurable consumption across time finally an application of this theory suggests that housing investment should face higher tax rates than nondurable consumption

take up and targeting experimental evidence from snap this paper develops a framework for evaluating the welfare impact of various interventions designed to increase take up of social safety net programs in the presence of potential behavioral biases we calibrate the key parameters using a randomized field experiment in which 30 000 elderly individuals not enrolled in but likely eligible for the supplemental nutrition assistance program snap are either provided with information that they are likely eligible provided with this information and also offered assistance in applying or are in a status quo control group only 6 percent of the control group enrolls in snap over the next 9 months compared to 11 percent of the information only group and 18 percent of the information plus assistance group the individuals who apply or enroll in response to either intervention receive lower benefits and are less sick than the average enrollee in the control group the results are consistent with the existence of optimization frictions that are greater for needier individuals suggesting that the poor targeting properties of the interventions reduce their welfare gains

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

housing taxation and capital accumulation this paper studies the impact of the preferential tax treatment of housing capital in a dynamic general equilibrium life cycle economy populated by heterogeneous individuals the model includes the main housing tax provisions currently in place in the u s and a minimum downpayment requirement upon purchasing non divisible houses the tax code makes the return on housing capital larger than that on business capital which distorts the lifetime profile and composition of individuals savings the wedge between the two rates of return emanates from the failure to tax imputed rents and is amplified by the presence of mortgage interest deductibility simulations show that individuals at all income levels would rather live in a world where imputed rents are taxed or one where mortgage interest payments are not deductible furthermore distributional effects are much smaller than conventionally believed

consumption dynamics during recessions when will durable expenditures respond strongly to economic stimulus we build from micro evidence and show that in a heterogeneous agent business cycle model with xed costs of durable adjustment responsiveness is substantially dampened during recessions our model estimates imply that during the great recession durable expenditures were half as responsive to additional stimulus as during the boom in the 1990s this procyclical responsiveness is driven by changes in the distribution of households desired durable holdings over the cycle we directly test our model by estimating this distribution empirically using psid micro data and nd that the distribution in the data moves cyclically as predicted in addition to this micro evidence we also provide support for our model s procyclical responsiveness using aggregate time series data and we show this time series evidence is inconsistent with simpler models featuring smooth adjustment costs

why is consumption so smooth for thirty years it has been accepted that consumption is smooth because permanent income is smoother than measured income this paper considers the evidence for the contrary position that permanent income is in fact less smooth than measured income so that the smoothness of consumption cannot be straightforwardly explained by permanent income theory the paper argues that in postwar u s quarterly data consumption is smooth because it responds with a lag to changes in income

are snap benefits adequate a geographical and food expenditure decomposition abstract the supplemental nutrition assistance program snap provides resources to supplement household food expenditures in order to achieve a nutritious diet determining the amount of support required or extent of food expenditure poverty entails comparing available resources for food to a nutrition determined threshold clearly the value of the threshold will affect the degree of food expenditure poverty if the threshold value is inaccurate the calculated degree of poverty will be inaccurate usda uses a threshold for setting snap benefits that does not vary geographically or temporally so consequently food expenditure poverty may be understated or overstated in different regions and time periods this article compares food expenditure poverty estimates for snap participants when geographical differences in the threshold are ignored versus not ignored in addition the article decomposes household food expenditures into food away from home fafh food at home fah personal funded fah and snap funded fah in order to assess the degree to which each of these contribute to reducing food expenditure poverty the general findings are that all food expenditure poverty measures are worse when geographical differences are taken into account in addition the analysis shows that fah expenditures and in particular snap fah expenditures contribute the most to reducing food expenditure poverty in snap households the policy implications are that food expenditure poverty is currently underestimated in the us by ignoring geographical differences in thresholds but the food expenditure poverty would be even worse without snap benefits geographical adjustments to the national threshold could help reduce food expenditure poverty across regions

aging in place housing maintenance and reverse mortgages we study the role of housing wealth in financing retirement consumption in our model retirees 1 derive utility benefits from remaining in their home aging in place and 2 choose in each period whether to maintain their house the evidence that we present shows that these features are important in explaining the saving decisions of the elderly the costs and the maintenance requirement of reverse mortgages rms reduce or eliminate the benefits of the loans for retirees who wish to do less maintenance we evaluate the impact of different loan features on retirees utility cash flows to lenders and to the government agency that provides mortgage insurance we show that combining rms with insurance against a forced home sale e g due to a move to a nursing home is pareto improving and can lead to increased demand for the loans due to product complementarities

how are snap benefits spent evidence from a retail panel we use a novel retail panel with more than six years of detailed transaction records to study the effect of participation in the supplemental nutrition assistance program snap on household spending we frame our approach using novel administrative data from the state of rhode island the marginal propensity to consume snap eligible food mpcf out of snap benefits is 0 5 to 0 6 the mpcf out of cash is much smaller these patterns obtain even for households for whom snap benefits are economically equivalent to cash in the sense that benefits do not cover all food spending we reject the hypothesis that households respect the fungibility of money in a semiparametric framework a model with mental accounting can match the facts

a dynamic model of housing demand estimation and policy implications a dynamic model of housing demand using data from the panel study of income dynamics psid we specify estimate and simulate a dynamic structural model of housing demand our model generalizes previous applied econometric work by incorporating realistic features of the housing market including non convex adjustment costs from buying and selling a home credit constraints from minimum downpayment requirements and uncertainty about the evolution of incomes and home prices we argue that these features are critical for capturing salient features of housing demand observed in the psid after estimating the model we use it to simulate how consumer behavior responds to house price and income declines as well as tightening credit these experiments are motivated by the u s recession starting in december of 2007 that saw large falls in home prices large negative income shocks for many households and tightening credit standards in the short run relatively few households adjust their housing stock households respond instead by reducing non housing consumption and reducing wealth because they wish to avoid losing their home and the associated adjustment costs households that adjust in the short run are those hit with a series of bad shocks such as a negative income shock and a home price decline a larger proportion of households do adjust their consumption in the long run increasing their housing stock since housing is less expensive however such changes may occur several years after the shocks listed above

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

permanent income liquidity and expenditure on automobiles evidence from panel data several recent papers have tested the permanent income cum rational expectations hypothesis using data on nondurable or semidurable consumption we show how this approach can be extended to the case of durables an application to panel data on automobile expenditures reveals no evidence against the permanent income hypothesis this result is unchanged in subsamples segregated by family holdings of liquid assets

choice inconsistencies among the elderly evidence from plan choice in the medicare part d program comment consumers enrollment decisions in medicare part d can be explained by abaluck and gruber s 2011 model of utility maximization with psychological biases or by a neoclassical version of their model that precludes such biases we evaluate these competing hypotheses by applying nonparametric tests of utility maximization and model validation tests to administrative data we find that 79 percent of enrollment decisions from 2006 to 2010 satisfied basic axioms of consumer theory under the assumption of full information the validation tests provide evidence against widespread psychological biases in particular we find that precluding psychological biases improves the structural model s out of sample predictions for consumer behavior

the sensitivity of consumption to transitory income estimates from panel data on households we investigate the stochastic relation between income and consumption specifically consumption of food within a panel of about 2 000 households our major findings are 1 consumption responds much more strongly to permanent than to transitory movements of income 2 the response to transitory income is nonetheless clearly positive 3 a simple test independent of our model of consumption rejects a central implication of the pure life cycle permanent income hypothesis the observed covariation of income and consumption is compatible with pure life cycle permanent income behavior on the part of80 percent of families and simple proportionality of consumption and income among the remaining 20 percent as a general matter our findings support the view that families respond differently to different sources of income variations in particular temporary income tax policies have smaller effects on consumption than do other more permanent changes in income of the same magnitude this abstract was borrowed from another version of this item

business models for sustainable biofuel transport the potential for intermodal transport the use of solid wood biofuels for energy production in heating plants has increased drastically during the last decades great interest has been shown in replacing unsustainable road transport of wood fuel with more sustainable intermodal transport this paper maps the common business models for biofuel transport in sweden and suggests how these models may be developed to accommodate intermodal transport a view of the biofuel supply chain as five overlapping networks industry material operations transport and infrastructure connected by four transaction markets sourcing operations transport and traffic have been used four typical business models have been found regional national biofuel company local biofuel company heating plant own account and wood processing industry cooperation and vertical integration among the actors are important to reach the large transport volumes required for intermodal transport key issues to increase the intermodal potential are increased vertical integration and cooperation sharing of transport resources and infrastructure joint purchases outsourcing to expert actors building trust and open communication and not underestimating the complexity of intermodal transport the results have implications for any actor interested in developing intermodal transport or policy measures the contribution includes the new approach of developing business models by using the five layer network market model

individual income incomplete information and aggregate consumption individual income is much more variable than aggregate per capita income i argue that aggregate information is therefore not very important for individual consumption decisions and study models of life cycle consumption in which individuals react optimally to their own income process but have incomplete or no information on economy wide variables since individual income is less persistent than aggregate income consumers will react too little to aggregate income variation aggregate consumption will be excessively smooth since aggregate information is slowly incorporated into consumption aggregate consumption will be autocorrelated and correlated with lagged income on the other hand the model has the same prediction for micro data as the standard permanent income model the second part of the paper provides empirical evidence on individual and aggregate income processes different models for individual income are fit to quarterly data from the survey of income and program participation making various adjustments for measurement error calibrating the consumption model using the estimated parameters for the income process yields predictions which qualitatively correspond to the empirical findings for aggregate consumption but do not match them well in magnitude

a system dynamic approach for exploring the effects of climate change risks on firms economic performance a number of studies have recently examined the potential relationships between climate change and the business community the majority of such studies have emphasized statistical and benchmarking techniques to identify how climate change could have implications on firms operations and their economic performance these techniques draw primary data from questionnaire surveys and corporate environmental reports in an ex post basis a fact that provide evidence in a linear probabilistic and static character these studies have provided limited insights regarding the future complex effects of climate change on corporate economic performance this paper aims to contribute to this literature by developing a dynamic model to investigate the evolutionary trends of the relationships between climate change risks financial performance and the operational processes of firms the main scope is to identify how physical regulatory reputational and litigation risks will affect day to day operations an integrated model will be established in order to improve managers and academics understanding of climate change and business performance four scenarios will also be tested to illustrate what if relationships in the presence of climate change risks finally the proposed model is based on the corporate climate change management system thinking system dynamic and stella software

house prices and consumer spending recent empirical work shows large consumption responses to house price movements this is at odds with a prominent theoretical view which using the logic of the permanent income hypothesis argues that consumption responses should be small we show that in contrast to this view workhorse models of consumption with incomplete markets calibrated to rich cross sectional micro facts actually predict large consumption responses in line with the data to explain this result we show that consumption responses to permanent house price shocks can be approximated by a simple and robust rule of thumb formula the marginal propensity to consume out of temporary income times the value of housing in our model consumption responses depend on a number of factors such as the level and distribution of debt the size and history of house price shocks and the level of credit supply each of these effects is naturally explained with our simple formula

the response of household consumption to income tax refunds a central implication of the life cycle or permanent income theory is that consumption should not respond to predictable fluctuations in income tests of this implication have yielded mixed results especially on micro data angus deaton 1992 martin browning and annamaria lusardi 1996 in large part this might be due to the difficulties of isolating the predictable component of income at the micro level most tests proceed by instrumenting for income but since the available instruments are typically poor such tests might be prejudiced against finding significant excess sensitivity of consumption to income john shea 1995 also it is not clear how closely the resulting econometric predictions of income coincide with agents actual expectations of income to avoid these difficulties this paper examines the response of household consumption to a particular type of income that is both predictable and transitory income tax refunds since a refund depends on events in the previous calendar year it is predictable income as regards consumption in the year of its receipt consequently under the life cycle theory consumption should not increase on receipt of a refund 2 in addition to testing the canonical model of consumption this paper provides estimates interpretable as the marginal propensity to consume mpc out of refunds since federal tax refunds now amount to over 80 billion per year averaging well over 1 000 per refund these estimates are of interest in themselves more generally they bear on the impact of even preannounced and temporary changes in fiscal policy the paper begins by surveying related studies in section i section ii describes the data the consumer expenditure survey cex which of the leading u s micro data sets has the most comprehensive coverage of expenditure the empirical specification is set out in section hi section iv reports the results and section v concludes

towards a renaissance in international business research big questions grand challenges and the future of ib scholarship in this article we review critiques of international business ib research with a focus on whether ib scholarship tackles big questions we identify three major areas where ib scholars have addressed important global phenomena but find that they have had little influence outside of ib and only limited effects on business or government policy we propose a redirection of ib research towards grand challenges in global business and the use of interdisciplinary research methods multilevel approaches and phenomena driven perspectives to address those questions we argue that ib can play a more constructive and vital role by tackling expansive topics at the business societal interface

individual dynamic managerial capabilities influence over environmental and social commitment under a gender perspective abstract the current business market is characterized by rapid and continuous changes companies should adapt to new situations to guarantee sustainable development managers need to have capabilities to understand the new environment s requirements managers individual dynamic capabilities idc help them face these unpredictable changes in the market however few authors have analysed individual dynamic capabilities to ensure business sustainability this study aims to shed light on the relationship between a manager s idc and business sustainability from a gender perspective a survey of 339 managers was conducted and structural equation modelling sem was applied to study the impact of the relationship the results show that managers individual dynamic capabilities help them detect changes in the market earlier and promote a greater social and environmental commitment from those managers in addition significant differences in the environmental and social commitment between men and women were found therefore this paper first provides advice for developing business sustainability to provide an advantage for organizations second individual dynamic managerial capabilities appear to be important for promoting sustainability finally another step in the construction of gender and sustainability is provided thus this paper provides useful empirical evidence for managerial practice from a strategic management viewpoint

consumer durables evidence on the optimality of usually doing nothing the authors argue that lumpy nonconvex transaction costs are the norm for a wide range of economic decisions which are thus characterized by inertial behavior application of this idea to the consumption of durable goods yields an s s decision rule which when aggregated highlights the different expected behavior of average expenditure per purchase versus the number of purchases the empirical implications of this rule are presented and compared to other theories a battery of empirical tests generally supports the predictions of the model in particular it does a good job of explaining the time pattern of response of spending on durables to a change in income copyright 1992 by ohio state university press

up to standard market positioning and performance of hong kong films 1975 1997 the trade off between conformity and differentiation that market entrants face has recently been enriched by a new sociological insight differentiation is rewarded only within the confines of taken for granted market categories entrepreneurs however routinely engage in combining existing market categories the present paper attempts to reconcile these seemingly different views by focusing on the role of market uncertainty in particular we predict that the propensity of entrants to blend multiple categories increases with market uncertainty upon considering the endogenous influence of uncertainty on market positioning the positive returns obtained by entrants from combining multiple categories become apparent because differentiation inspires the positioning of entrants in the face of market uncertainty the frequent adoption of the same combination by competitors dampens the performance returns derived from it our hypotheses find support from the analysis of a large sample of hong kong films during 1975 1997

consumption and risk sharing over the life cycle a striking feature of u s data on income and consumption is that inequality increases with age this paper asks if individual specific earnings risk can provide a coherent explanation we find that it can we construct an overlapping generations general equilibrium model in which households face uninsurable earnings shocks over the course of their lifetimes earnings inequality is exogenous and is calibrated to match data from the u s panel study on income dynamics consumption inequality is endogenous and matches well data from the u s consumer expenditure survey the total risk households face is decomposed into that realized before entering the labor market and that realized throughout the working years in welfare terms the latter is found to be more important than the former

the labeling effect of a child benefit system child benefit systems exist in many countries while they show a lot of differences in terms of eligibility rules amounts involved and implementation tax deduction tax credit or direct benefit the common motivation for their existence is to increase children s welfare in the dutch child benefit system the case i focus on in this paperone of the parents usually the mother is entitled to an untaxed child benefit amount which only depends on the child s age and the number of children in the household thus child support does not depend on household income marital status or labor market status as a result child benefit is exogenous to the household given the presence of children this is in contrast with the situation in many other countries including germany france the united kingdom and the united states where government provided child support is partly means tested see jonathan bradshaw et al 1993 in the netherlands child benefit is generally a nonnegligible addition to the household income the median share of child benefit in the total net income of households with children is 8 percent on the national level expenditures on child benefits amount to 1 2 percent of gnp the use of the child benefit is completely at the discretion of the parent there are no legal requirements that a certain amount be spent on particular goods or services nor does the government provide any guidelines regarding expenditure on children a policy question that arises is to what extent children benefit from child benefits standard microeconomic demand theory allows no role for effects of the composition of income given the fungibility of income sources it is only the sum of income components that is relevant in explaining expenditure patterns thus within that framework the answer would be that the marginal propensity to consume child goods from one guilder of child benefits is no different than from one guilder of any other income source in the more general class of gametheoretic models of household behavior however the composition of household income will generally affect expenditure patterns see e g shelly j lundberg and robert a pollak 1993 and martin browning et al 1994 if fathers and mothers have different preferences and mothers have control over child benefits the effect of child benefits on expenditures will differ from the effect of other income sources lundberg et al 1997 provide empirical evidence showing that a transfer of control over child benefits from fathers to mothers in the united kingdom due to a change in legislation resulted in a significant increase in expenditures on child clothing daniela del boca and christopher j flinn 1994 have analyzed the effect of income composition on expenditure decisions of divorced mothers they find that the coefficients associated with child support and alimony income differ from those for other income in engel curves for expenditures on childspecific goods their results can be explained in terms of a noncooperative nash model in which the child support transfer decisions of the noncustodial father and the expenditure decisions of the mother are determined simultaneously in contrast to del boca and flinn s analysis in which child support is a decision variable the present paper focuses on the possible differential effect of government provided child support which is truly exogenous in this paper i analyze the effects of child benefits on expenditures by running regressions in which child benefit enters as a separate explanatory variable the enipirical analysis is based on a time series of 17 cross section consumer expenditure surveys in the netherlands covering the period 1978 through 1994 it is important to note that in a single cross section it department of economics university of groningen p o b 800 9700 av groningen the netherlands e mail p kooreman eco rug nl i am indebted to two anonymous referees for constructive comments helpful comments were also provided by rob alessie maarten allers chris bojke werner de bondt bert schoonbeek and tom wansbeek i thank vincent linderhof for organizing the data financial support was provided by the dutch organization for scientific research nwo homes project grant

from green technology development to green innovation inducing regulatory adoption of pathogen detection technology for sustainable forestry technological entrepreneurship has been widely acknowledged as a key driver of modern industrial economies and more recently a panacea for environmental and social problems however our current understanding of how green technology ventures emerge and diffuse more sustainable innovations remains limited we advance theory on green entrepreneurship by drawing on institutional work to refine and extend our understanding of how entrepreneurs may influence government policies and practices in their attempts to diffuse green technology we develop a theoretical framework that combines institutional work with a search tool the technological commercial organizational and societal tcos framework of innovative uncertainties which identifies key opportunities hurdles and potential unintended consequences at early stages of technology development we present a detailed case study of a potential university based green tech venture developing pathogen detection technology for forestry protection foreign pathogens spread by international trade can have major detrimental impacts on forests and the industries that rely on them our analysis found that green technology demonstrating technological feasibility is necessary but not sufficient green tech ventures must also engage in institutional work in this case articulating the technology s benefits to regulators to establish legitimacy and avoid misuse that can hinder its adoption we thus add to previous studies by emphasizing that institutional work could be a main activity for a green tech venture a core entrepreneurial strategy rather than an afterthought

the risk free rate in heterogeneous agent incomplete insurance economies abstract why has the average real risk free interest rate been less than one percent the question is motivated by the failure of a class of calibrated representative agent economies to explain the average return to equity and risk free debt i construct an economy where agents experience uninsurable idiosyncratic endowment shocks and smooth consumption by holding a risk free asset i calibrate the economy and characterize equilibria computationally with a borrowing constraint of one year s income the resulting risk free rate is more than one percent below the rate in the comparable representative agent economy

the retirement savings puzzle reviewed the role of housing and bequests the so called retirement savings puzzle is a phenomenon by which contrary to what the standard life cycle model predicts households do not run down their wealth significantly during retirement in this review paper we survey the literature on the retirement savings puzzle and we connect it with the literature on housing equity during retirement to establish a link between these two streams of literature we use as a framework the work of nakajima and telyukova 2013a home equity in retirement ucsd working paper and nakajima and telyukova 2017 reverse mortgage loans a quantitative analysis journal of finance 72 911 950 who find that home ownership interacts with factors that explain the retirement savings puzzle notably with the bequest motive we complement the results by nakajima and telyukova by relating them to the literature on altruistic bequests strategic bequests and housing as a commitment device all of which give further insights on the connection between home ownership and bequests we complement our review of the literature with descriptive evidence using the netherlands as a case study

liquidity constraints and intertemporal consumer optimization theory and evidence from durable goods this paper develops and tests the implications of optimal consumption behavior with borrowing constraints the theory shows that liquidity constraints imply a distinctive intertemporal relationship between durable and nondurable goods consumption binding liquidity constraints appear as part of an error correction term derived from the long run cointegrating relationship between durables and nondurables when liquidity constraints are binding the error correction term will have predictive power for the future change in nondurable consumption empirical tests of the implications using aggregate data support the hypothesis that liquidity constraints rather than rule of thumb behavior best explain the excess sensitivity of consumption to predictable changes in income copyright 1995 by ohio state university press

house prices and risk sharing homeowners in the panel study of income dynamics are able to maintain a high level of consumption following job loss or disability in periods of rising local house prices while the consumption drop for homeowners who lose their job in times of lower house prices is substantial these results are consistent with homeowners being able to access wealth gains when housing appreciates as witnessed by their ability to smooth consumption more than renters a calibrated model of endogenous homeownership and consumption is able to reproduce the patterns in the data quite well and provides an interpretation of the empirical results

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

sustainable development and entrepreneurship past contributions and future directions this article discusses the emerging research concerned with sustainable development and entrepreneurship which is the focus of this special issue of the journal of business venturing entrepreneurship has been recognized as a major conduit for sustainable products and processes and new ventures are being held up as a panacea for many social and environmental concerns however there remains considerable uncertainty regarding the nature of entrepreneurship s role and how it may unfold we begin with an overview of sustainable development and the role of entrepreneurship and outline recent contributions exploring this role we then summarize the papers presented in this special issue and conclude with suggestions for further research

housing over time and over the life cycle a structural estimation we estimate a structural model of optimal life cycle housing and nonhousing con sumption in the presence of labor income and house price uncertainties the model postulates constant elasticity of substitution between housing service and nonhousing consumption and explicitly incorporates a housing adjustment cost our estimationts the cross sectional and time series household wealth and housing proles from the panel study of income dynamics 1984 to 2005 reasonably well and suggests an intratemporal elasticity of substitution between housing and nonhousing consumption of 0 487 the low elasticity estimate is largely driven by moments conditional on state house prices and moments in the latter half of the sample period and is robust to different assumptions of housing adjustment cost we then conduct policy analyses in which we let house price and income take values as those observed between 2006 and 2011 we show that the responses depend importantly on the housing adjustment cost and the elasticity of sub stitution between housing and nonhousing consumption in particular compared with the benchmark the impact of the shocks on homeownership rates is reduced but the impact on nonhousing consumption is magnied when the house selling cost is sizable or when housing service and nonhousing consumption are highly substitutable

home is where the equity is mortgage refinancing and household consumption applying a permanent income model with exogenous liquidity constraints and mortgage behavior household refinancing when mortgage interest rates are historically high and rising a persistent empirical puzzle is explained using data from the panel study of income dynamics households experiencing an unemployment shock and having limited initial liquid assets to draw upon are shown to have been 25 more likely to refinance 1991 94 on average such liquidity constrained households converted over two thirds of every dollar of equity they removed into current consumption as mortgage rates plummeted 1991 94 producing an estimated expenditure stimulus of at least 28 billion
