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

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

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

quantity competition with access fees abstract we analyze an oligopoly model where firms choose both quantities and access fees per unit prices are determined endogenously to equate quantity demanded with quantity supplied at each firm in a nash equilibrium of the game played by firms the per unit prices equal marginal cost and access fees may or may not extract all consumer surplus as the number of firms increases access fees fall below net consumer surplus and toward zero existence is guaranteed if marshallian consumer surplus is not too concave with open entry quantity competition with access fees may be less efficient than without access fees

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

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

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

housing markets with indivisibilities abstract a model of a rental housing market in which houses are treated as indivisible commodities is presented a recursive equation that determines a competitive equilibrium is provided and it is argued that this competitive equilibrium is representative of the set of all competitive equilibria using this representative equilibrium several propositions on comparative statics are considered that have to do with how the competitive rents change when certain parameters of the model change

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

competitive equilibrium with indivisibilities abstract this paper studies an exchange economy with a finite number of agents in which each agents is initially endowed with a finite number of personalized indivisible commodities we observe that the equivalence theorem of the core and the competitive equilibrium may not hold for this economy when the coalitional form game is generated in the standard manner we provide an alternative definition of the coalitional form game to resolve this problem so that the balancedness of the new defined game provides a useful necessary and sufficient condition for the existence of competitive equilibrium for the original economy journal of economic literature classification numbers c71 d41 d51

a competitive market model for indivisible commodities abstract a general competitive market model for trading indivisible goods is introduced there are a group of traders and several indivisible goods each trader is initially endowed with several units of each indivisible good and some amount of money traders have preferences over the bundle of indivisible goods and the quantity of money they consume it is shown that the market has a walrasian equilibrium if and only if an associated linear program problem has an optimal solution with its value equal to the potential market value and that the equilibrium prices of the goods and the profits of the traders are the optimal solutions of the linear program problem

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

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

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

a just and efficient reduction of resource throughput to optimum abstract resource throughput in the economy e g of energy or materials must be progressively reduced by at least one order of magnitude to achieve an optimal level although this would solve the resource distribution conflict between the generations it would also aggravate the resource distribution conflict between persons of the same generation it is shown here that a solution to these two conflicts and efficient resource allocation are only possible if resource certificates are distributed to consumers free of charge and traded between them this paper builds on and integrates ideas developed in h daly s daly h e 1992 allocation distribution and scale towards an economics that is efficient just and sustainable ecological economics 6 185 193 article on allocation distribution and scale adding insights from the ecological footprint concept to propose a mechanism for facilitating intergenerational equity and drastically reducing resource throughput basically the mechanism involves rationing throughput equitably internalizing environmental and social externalities and substituting labour for resource use this can be achieved almost without a drop in prosperity both unemployment and dependence on scarce resources decline

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

increased ecoefficiency and gross rebound effect evidence from usa and six european countries 1960 2002 despite increased efficiency in the use of natural resources the use of these resources continues to increase in most societies this paper examines the discrepancy between the potential decrease of use of natural resources as an effect of increased efficiency and actual use during the period 1960 2002 this difference was found to grow faster in the usa than the mean for six west european countries possible reasons for this difference between the two regions are analysed to reduce the anthropogenic flows of energy and material and the consequent deleterious effects on the biosphere it will become necessary to adapt consumption to degree of efficiency in the use of natural resources based on the comparison between the two regions some economic aspects of this issue are discussed

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

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

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

cores and competitive equilibria with indivisibilities and lotteries abstract lotteries are introduced in the exchange model of shapley and scarf j math econ 1 1974 23 37 in competition traders buy and sell probabilities on houses when considering the core feasible allocations of the economy and blocking allocations of coalitions may involve lotteries among other results we show that the set of lottery equilibrium allocations is non empty and does not contain all competitive equilibrium allocations the core of the shapley scarf model is a strict subset of the lottery core and lottery equilibrium allocations are contained in the lottery core journal of economic literature classification numbers c62 c71

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

rethinking productivity why has productivity focussed on labour instead of natural resources the contribution of natural resources and ecosystems to economic processes still remains under assessed by market evaluation and productivity analysis following the historical lines of the classical productivity debate ranging from the french physiocrats to early neoclassical growth theories the productivity concept underwent a gradual transformation from its previous understanding based on natural resources and other environmental factors to its contemporary narrow notion this paper claims that the course of the classical debate has shaped the scope of predominant contemporary analysis except for some very recent findings multifactor productivity largely focusses on a two factor model material flow analysis mfa provides a useful step for widening the measurement and notion of productivity

trade and the environment from a southern perspective the relationship between free trade and the environment is one of the main issues of contention between environmental and ecological economics environmental economics assumes a positive relationship between free trade economic growth and environmental policies environmental externalities may cause important damage however trade is not to be blamed for this instead the fault lies with policy inadequacies at the national level on the other hand some ecological economists criticise the assumptions of environmental economics especially the immobility of production factors and the positive correlation between income and environmental quality they plead for measures to prevent deterioration of northern environmental standards in a race to the bottom due to ecological dumping from the south in this paper we argue that neither environmental economics nor northern ecological economics take into account the structural conditions determining the international trade system based on some new empirical evidence on material flows we stress the notion of environmental cost shifting if physical and political ecology perspectives are adopted a southern approach to the trade and environment issue may arise 2001 elsevier science b v all rights reserved

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

competitive equilibria in two sided matching markets with general utility functions we present an exact characterization of utilities in competitive equilibria of two sided matching markets in which the utility of each agent depends on the choice of partner and the terms of the partnership potentially including monetary transfer examples of such markets include sellers and buyers or jobs and workers demange and gale showed that the set of competitive equilibria in this type of market forms a complete lattice with each extreme point of the lattice representing an equilibrium with the highest utilities for the agents on one side and the lowest utilities for the agents on the opposite side our characterization is based on establishing a connection between the competitive equilibria of a market and the competitive equilibria of certain strict subsets of that market each obtained by removing exactly one agent this characterization captures the effect of competition when agents are added to the market or removed from the market it gives a precise procedure for constructing competitive eq

economic structure and energy savings from energy efficiency in households when an energy efficiency improvement occurs at the household level several mechanisms grouped under the name of the rebound effect increase the available income and consumption increasing the total energy consumption of the economic structure the present research analyses the links between energy efficiency improvements in households consumption and the economic structure in an input output framework we examine from an empirical perspective the relationship between energy efficiency improvements and the economic structure and between the direct and the indirect rebound effect the limits of the input output methodology in assessing the direct and indirect rebound effect have been empirically tested with respect to efficiency improvements of electricity uses in households in catalonia

the existence and computation of competitive equilibria in markets with an indivisible commodity abstract this paper considers an exchange economy called a generalized assignment market in which sellers and buyers trade one indivisible commodity possibly with product differentiation for a perfectly divisible commodity the existence of a competitive equilibrium in this economy is proved using kakutani s fixed point theorem this existence theorem is applied to a production economy in which sellers are formulated as producers with convex cost functions two examples of housing markets are provided and their competitive equilibria are numerically calculated

existence and welfare properties of equilibrium in an exchange economy with multiple divisible indivisible commodities and linear production technologies abstract in this paper we consider a class of economies with a finite number of divisible commodities linear production technologies and indivisible goods and a finite number of agents this class contains several well known economies with indivisible goods and money as special cases it is shown that if the utility functions are continuous on the divisible commodities and are weakly monotonic both on one of the divisible commodities and on all the indivisible commodities if each agent initially owns a sufficient amount of one of the divisible commodities and if a no production without input like assumption on the production sector holds then there exists a competitive equilibrium for any economy in this class the usual convexity assumption is not needed here furthermore by imposing strong monotonicity on one of the divisible commodities we show that any competitive equilibrium is in the core of the economy and therefore the first theorem of welfare also holds we further obtain a second welfare theorem stating that under some conditions a pareto efficient allocation can be sustained by a competitive equilibrium allocation for some well chosen redistribution of the total initial endowments journal of economic literature classification numbers d4 d46 d5 d51 d6 d61

competitive equilibrium in an exchange economy with indivisibilities abstract we analyze an exchange economy in which i all commodities except money are indivisible ii agents preferences can be described by a reservation value for each bundle of indivisible objects and iii all agents are price takers we obtain a necessary and sufficient condition under which market clearing prices exist implications for market mechanisms are discussed journal of economic literatureclassification numbers d51 c78

a competitive partnership formation process a group of heterogeneous agents may form partnerships in pairs all single agents as well as all partnerships generate values if two agents choose to cooperate they need to specify how to split their joint value among one another in equilibrium which may or may not exist no agents have incentives to break up any existing partnerships or form new partnerships this paper proposes a dynamic competitive adjustment process that always either finds an equilibrium or exclusively disproves the existence of any equilibrium in finitely many steps when an equilibrium exists partnership and revenue distribution will be automatically and endogenously determined by the process moreover several fundamental properties of the equilibrium solution and the model are derived

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

multi item auctions a collection of items is to be distributed among several bidders and each bidder is to receive at most one item assuming that the bidders place some monetary value on each of the items it has been shown that there is a unique vector of equilibrium prices that is optimal in a suitable sense for the bidders in this paper we describe two dynamic auction mechanisms one achieves this equilibrium and the other approximates it to any desired degree of accuracy

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

bundling decisions by a multiproduct monopolist with incomplete information this paper analyzes bundling decisions of a rnultiproduct monopolist facing uncertain demand the monopolist sells his products using an auction mechanism and the market is analyzed as a game with incomplete information in which the buyers as well as the seller are strategic agents with a small number of buyers a profit maximizing seller will bundle all his output this makes buyers uniformly worse off compared to the case where the same monopolist does not bundle in the sense that any buyer is worse off regardless of his demand for the monopolist s outputs with a larger number of buyers the seller will have a tendency to unbundle his output and high demand buyers are worse off than they would be if the monopolist bundled his output low demand buyers on the other hand are always better off when the monopolist unbundles his output regardless of the number of competing buyers despite the fact that high demand buyers are the typical purchasers of the monopolist s output the net effect of increasing the number of buyers is greater market efficiency since bundling creates market inefficiencies both ex post and ex ante

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

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

a double sided multiunit combinatorial auction for substitutes theory and algorithms combinatorial exchanges have existed for a long time in securities markets in these auctions buyers and sellers can place orders on combinations or bundles of different securities these orders are conjunctive they are matched only if the full bundle is available on business to business b2b exchanges buyers have the choice to receive the same product with different attributes for instance the same product can be produced by different sellers a buyer indicates his preference by submitting a disjunctive order where he specifies the quantity he wants of each particular good and what limit price he is willing to pay for each good thus providing a subjective valuation of each attribute only the goods with the best prices will be traded this article considers a doubled sided multiunit combinatorial auction for substitutes that is a uniform price auction where buyers and sellers place both types of orders conjunctive and orders and disjunctive xor orders we show that linear competitive prices exist we also propose an algorithm to clear the market which is particularly efficient when the number of traders is large and the goods are divisible

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

duality in comparative statics in rental housing markets with indivisibilities we present certain duality results on comparative statics on competitive rent vectors in the rental housing market model in the model apartments as indivisible goods are classified into a finite number of categories and are traded for one composite commodity our concern is about certain general properties of the behavior of rents with parameter changes in particular the rent changes are intimately related to the boundary income changes of the categories of apartments both changes are endogenously determined in equilibrium we will show that these changes exhibit nice dual structures we will also apply our model and comparative statics to a rental housing market in the tokyo metropolitan area

the self regulating profession slayton and treblicock 1978 the formal analysis of the economics of the self regulating profession has received little attention from theorists if a profession is self regulating in the sense that its current members being the sole suppliers of a certain type of service are free to determine in one way or another whether or not to admit a potential recruit then it might seem prima facie that such a profession could simply be regarded as a monopolistic seller of the service in question so that the effects of self regulation would appear to involve an unambiguous welfare loss the whole rationale for self regulation however rests on the notion that it provides a vehicle through which the quality of the service may be maintained in markets where the consumer cannot readily measure this quality himself it is the analysis of the interplay of these two elements the enhanced price of such services associated with the monopolistic power of the profession and the improved quality of the service which may accompany a reduction in supply which forms the focus of the present paper it is tempting to begin the analysis of such a profession by first positing some particular
