toward a reconstruction of keynesian economics expectations and constrained equilibria a two period model of temporary equilibrium with rationing is presented paying particular attention to agents expectations of future constraints it is shown that with arbitrary constraint expectations many different types of current equilibrium may be consistent with the same set of current and expected future wages and prices and that constraint expectations exhibit bootstraps properties e g a higher expectation of keynesian unemployment tomorrow increases the probability that it will prevail today in addition the concept of rational constraint expectations i e perfect foresight of future constraints is introduced and shown to enhance rather than reduce the effectiveness of government policy

the labour augmented k s model a laboratory for the analysis of institutional and policy regimes abstract in this work we discuss the research findings from the labour augmented schumpeter meeting keynes k s agent based model it comprises comparative dynamics experiments on an artificial economy populated by heterogeneous interacting agents as workers firms banks and the government the exercises are characterized by different degrees of labour flexibility or by institutional shocks entailing labour market structural reforms wherein the phenomenon of hysteresis is endogenous and pervasive the k s model constitutes a laboratory to evaluate the effects of new institutional arrangements as active passive labour market policies and fiscal austerity in this perspective the model allows mimicking many of the customary policy responses which the european union and many latin american countries have embraced in reaction to the recent economic crises the obtained results seem to indicate however that most of the proposed policies are likely inadequate to tackle the short term crises consequences and even risk demoting the long run economic prospects more objectively the conclusions offer a possible explanation to the negative path traversed by economies like brazil where many of the mentioned policies were applied in a short period and hint about some risks ahead

the future of macroeconomics macro theory and models at the bank of england abstract the adoption as policy models by central banks of representative agent new keynesian dynamic stochastic general equilibrium models has been widely criticised including for their simplistic micro foundations at the bank of england the previous generation of policy models is seen in its 1999 medium term macro model mtmm instead of improving that model to correct its considerable flaws many shared by other non dsge policy models such as the federal reserve s frb us it was replaced in 2004 by the dsge based beqm though this clearly failed during and after the global financial crisis it was replaced in 2011 by the dsge compass complemented by a suite of models we provide a general critique of dsge models for explaining forecasting and policy analyses at central banks and suggest new directions for improving current empirical macroeconomic models based on empirical modelling broadly consistent with better theory rather than seeking to impose simplistic and unrealistic theory

macroeconomic forecasting in the euro area country specific versus area wide information abstract this paper compares several time series methods for short run forecasting of euro wide inflation and real activity using data from 1982 to 1997 forecasts are constructed from univariate autoregressions vector autoregressions single equation models that include euro wide and us aggregates and large model methods in which forecasts are based on estimates of common dynamic factors aggregate euro wide forecasts are constructed from models that utilize only aggregate euro wide variables and by aggregating country specific models the results suggest that forecasts constructed by aggregating the country specific models are more accurate than forecasts constructed using the aggregate data

sulfur dioxide control by electric utilities what are the gains from trade title iv of the 1990 clean air act amendments caaa established a market for transferable sulfur dioxide so2 emission allowances among electric utilities this market offers firms facing high marginal abatement costs the opportunity to purchase the right to emit so2 from firms with lower costs and this is expected to yield cost savings compared to a command and control approach to environmental regulation this paper uses econometrically estimated marginal abatement cost functions for power plants affected by title iv of the caaa to evaluate the performance of the so2 allowance market specifically we investigate whether the much heralded fall in the cost of abating so2 compared to original estimates can be attributed to allowance trading we demonstrate that for plants that use low sulfur coal to reduce so2 emissions technical change and the fall in prices of low sulfur coal have lowered marginal abatement cost curves by over 50 percent since 1985 the flexibility to take advantage of these chan

high tech firms and credit rationing abstract informational frictions between borrowers and lenders differ across classes of borrowers innovative firms undertake high risk high return projects which are likely to be little understood by financial intermediaries as a consequence they may end up allocating too large a share of funds to traditional low risk low return projects this proposition finds some support in a cross section of italian manufacturing firms using several proxies to classify firms into high tech and low tech groups and direct information on each firm s access to bank credit high tech firms are found to be more likely to be credit constrained than low tech firms the results suggest that the responsiveness of r d expenditure to cash flow found in the literature is likely due to pervasive credit constraints on innovative firms rather than to cash flow proxying for future expectations the paper also sheds light on the main factors affecting the probability of a firm being rationed in the credit market

excessive volatility in capital flows a pigouvian taxation approach this paper analyzes prudential controls on capital flows to emerging markets from the perspective of a pigouvian tax that addresses externalities associated with the deleveraging cycle it presents a model in which restricting capital inflows during boom times reduces the potential outflows during busts this mitigates the feedback effects of deleveraging episodes when tightening financial constraints on borrowers and collapsing prices for collateral assets have mutually reinforcing effects in our model capital controls reduce macroeconomic volatility and increase standard measures of consumer welfare

the effect of business risk on manufacturing investment sectoral survey evidence from ireland abstract this paper analyses the results of a special sample survey on risk and investment carried out using the european union investment survey sampling frame for ireland the paper looks at decision making by large manufacturing firms located in ireland to see whether their investment decisions can be understood within the various models of risk that economists use equilibrium and disequilibrium models are examined to see what best explains the behaviour revealed by the firms responses the paper develops a categorisation of the main theoretical channels of influence from risk to investment in the light of this theory the survey replies of irish firms are used to assess the importance of the different channels of influence

debt deleveraging and the liquidity trap a fisher minsky koo approach in this paper we present a simple new keynesian style model of debt driven slumps that is situations in which an overhang of debt on the part of some agents who are forced into rapid deleveraging is depressing aggregate demand making some agents debt constrained is a surprisingly powerful assumption fisherian debt deflation the possibility of a liquidity trap the paradox of thrift a keynesiantype multiplier and a rationale for expansionary fiscal policy all emerge naturally from the model we argue that this approach sheds considerable light both on current economic difficulties and on historical episodes including japan s lost decade now in its 18th year and the great depression itself

price flexibility credit availability and economic fluctuations evidence from the united states 1894 1909 the importance of disturbances in financial markets for real economic activity and the positive association between price level and output movements typically are explained by appeal to a combination of nominal aggregate demand shocks particularly money supply shocks and rigid prices we argue that this view is inconsistent with evidence for short run responsiveness of prices and gold flows to nominal disturbances during the pre world war i gold standard era we offer an alternative explanation that connects financial markets and real activity through disturbances to the availability of credit this approach links comovements in prices and output through real effects in credit markets associated with price level shocks empirical analysis using monthly data for the pre world war i period supports the assumption of rapid price adjustment and the credit supply interpretation of the transmission of financial shocks disturbances to credit availability including price shocks contribute substantially to our empirical explanation of output fluctuations during this period

uncertainty and growth of the firm using data from a survey of 1 097 small and medium sized non listed dutch firms we investigate the relation between growth of the firm and uncertainty we focus on the impact of sales uncertainty on various types of investment we find that sales uncertainty measured by the conditional variance has a mixed impact on various investment decisions we include an analysis of the relevance of financial structure and firm size on the growth uncertainty relation

decoupling and recoupling we develop a stylized model that captures the phenomena of decoupling and recoupling in an environment where heterogeneous entrepreneurial sectors face financial constraints in their relationship with a common set of lenders in response to adverse shocks a financially constrained sector must reduce its borrowing and cut down on production in particular as the constrained sector absorbs less and less capital the real interest rate in the economy declines other sectors that compete for the same inputs including capital thus experience lower costs which boosts investment output and profits reflecting the phenomenon of decoupling as long as the shock is small the entrepreneurial sector repays what is owed and the lenders ability to supply funds is unaffected for large shocks however the constrained sector is no longer able to honor its debts in full and lenders experience losses that erode their lending base this induces them to cut their supply of credit to the rest of the economy which reduces output and profit for all other entrepreneurial sectors capturing the phenomenon of recoupling or contagion this abstract was borrowed from another version of this item

a comparison of autoregressive univariate forecasting procedures for macroeconomic time series the actual performance of several automated univariate autoregressive forecasting procedures applied to 150 macroeconomic time series are compared the procedures are the random walk model as a basis for comparison long autoregressions with three alternative rules for lag length selection and a long autoregression estimated by minimizing the sum of absolute deviations the sensitivity of each procedure to preliminary transformations data periodicity forecast horizon loss function employed in parameter estimation and seasonal adjustment procedures is examined the more important conclusions are that akaike s lag length selection criterion works well in a wide variety of situations the modeling of long memory components becomes important for forecast horizons of three or more periods and linear combinations of forecasts do not improve forecast quality appreciably

potential pitfalls for the purchasing power parity puzzle sampling and specification biases in mean reversion tests of the law of one price the ppp puzzle is based on empirical evidence that international price differences for individual goods loop or baskets of goods ppp appear highly persistent or even nonstationary the present consensus is these price differences have a half life that is of the order of five years at best and infinity at worst this seems unreasonable in a world where transportation and transaction costs appear so low as to encourage arbitrage and the convergence of price gaps over much shorter horizons typically days or weeks however current empirics rely on a particular choice of methodology involving i relatively low frequency monthly quarterly or annual data and ii a linear model specification in fact these methodological choices are not innocent and they can be shown to bias analysis towards findings of slow convergence and a random walk intuitively if we suspect that the actual adjustment horizon is of the order of days then monthly and annual data cannot be expected to reveal it if we suspect arbitrage costs are high enough to produce a substantial band of inaction then a linear model will fail to support convergence if the process spends considerable time random walking in that band thus when testing for ppp or loop model specification and data sampling should not proceed without consideration of the actual institutional context and logistical framework of markets

consumer spending and the economic stimulus payments of 2008 abstract we measure the change in household spending caused by receipt of the economic stimulus payments of 2008 using questions added to the consumer expenditure survey and variation from the ran

the liability insurance market t his paper offers an overview of the u s liability insurance market and the link between its performance and developments in tort law over the last few decades the dominant feature of the insurance market has been the intermittent periods of rapidly rising premiums and cutbacks on the availability of coverage the insurance cycle appears to be increasing in amplitude and since the 1960s has been concentrated increasingly in liability lines an episode of rising premiums in the late 1960s was followed by a six year period of declining and eventually negative growth rates in total liability insurance premiums over the 1975 1977 period the annual growth rate jumped to 30 percent then followed another period of declining real premiums until premiums nearly tripled in 1984 1986 accompanied by cancellations of policies and massive withdrawal of insurers from some lines this crisis had an economic impact beyond the insurance market leading to the withdrawal of many goods and services from u s markets in mid 1987 the market began to turn again with premiums falling by as much as 40 percent for some commercial policies since then aggregate revenue from premiums has been relatively stable the liability insurance market is intertwined with the tort system in addition to providing incentives to avoid accidents the tort system allocates the risks of accident costs in providing compensation for accident victims the modern expansion of liability in tort law as described by priest in this issue represents a shift in the burden of supplying insurance from first party insurance markets to liability or third party insurance markets clearly this shift will

a financial macro network approach to climate policy evaluation abstract existing approaches to assess the economic impact of climate policies tend to overlook the financial sector and to focus only on direct effects of policies on the specific institutional sector they target neglecting possible feedbacks between sectors thus underestimating the overall policy effect to fill in this gap we develop a methodology based on financial networks which allows for analyzing the transmission throughout the economy of positive or negative shocks induced by the introduction of specific climate policies we apply the methodology to empirical data of the euro area to identify the feedback loops between the financial sector and the real economy both through direct and indirect chains of financial exposures across multiple financial instruments by focusing on climate policy induced shocks that affect directly either the banking sector or non financial firms we analyze the reinforcing feedback loops that could amplify the effects of shocks on the financial sector and then cascade on the real economy our analysis helps to understand the conditions for virtuous or vicious cycles to arise in the climate finance nexus and to provide a comprehensive assessment of the economic impact of climate policies

foreign currency debt risk premia and macroeconomic volatility abstract this paper studies the relationships between foreign currency debt macroeconomic volatility and risk premia in a model of a small open emerging market economy the external value of the local currency is counter cyclical so that foreign currency debt requires larger repayments than local currency debt in bad states of nature the level of foreign currency denominated debts therefore affects the volatility of aggregate demand and by extension of the exchange rate exchange rate volatility is in turn an important determinant of the risk premium on local currency debt finally this risk premium is a major factor in the choice of local versus foreign currency for emerging market borrowers the mutual endogeneity of foreign currency debt risk premia and macroeconomic volatility creates important feedback effects in the economy small increases in international risk aversion may entail large amplification effects on macroeconomic volatility since domestic borrowers substitute towards cheaper but riskier foreign currency debt finance

inventories sales uncertainty and financial strength abstract we investigate the empirical linkages between sales uncertainty and firms inventory investment behavior while controlling for firms financial strength using large panels of manufacturing firms from several european countries we find that higher sales uncertainty leads to larger stocks of inventories we also identify an indirect effect of sales uncertainty on inventory accumulation through the financial strength of firms our results provide evidence that financial strength mitigates the adverse effects of uncertainty

agritourism and off farm work survival strategies for small farms this study considers agritourism and off farm work as income diversification choices simultaneously and analyzes factors influencing such choices further the study assesses the impact of agritourism off farm work and both on gross cash farm income and total farm household income we utilized large set of nationwide farm survey data and selectivity based multinomial choice model an important finding of our study is that small farms have higher household income if they choose both income diversification strategies rather than a single strategy results suggest that education age of the operator financial condition and location of the farm are important factors driving income diversification alternatives finally our study indicates that accounting for selectivity is essential to ensure unbiased and consistent estimates

consumption during retirement the missing link in the life cycle this study presents the first evidence on the relation of consumption to lifetime wealth based on data from the 1973 and 1975 retirement history survey that have been linked to social security earnings records nearly 500 white married fully retired couples ages 62 69 form the basis of the analysis on average their consumption early in retirement exceeds by 14 percent the income that their financial pension and social security wealth can generate this implies that their saving both private and through social security is insufficient to sustain consumption throughout the rest of their lives additional evidence based on changes in spending between 1973 and 1975 shows that these households respond by reducing their real consumption at a rate sufficient to generate positive changes in net financial worth within a few years after retirement these two pieces of evidence can be rationalized by a rate of time preference much higher than the interest rate coupled with either a bequest motive or uncertainty about the length of life they also imply that even when combined with private pensions and savings social security in the united states today does not enable most recipients to maintain their living standard at the levels they enjoyed before they retired this abstract was borrowed from another version of this item

r d and internal finance a panel study of small firms in high tech industries since joseph schumpeter economists have argued that internal finance should be an important determinant of r d expenditures yet almost without exception previous empirical studies have not found evidence of such a relation using newly available data the authors investigate this puzzle with a panel of 179 small firms in high tech industries under each estimation strategy they employ the authors find an economically large and statistically significant relationship between r d investment and internal finance their results are consistent with the view that because of capital market imperfections the flow of internal finance is the principal determinant of the rate at which small high tech firms acquire technology through r d copyright 1994 by mit press

aggregation of heterogeneous time preferences we examine an economy whose consumers have different discount factors for utility possibly not exponential we characterize the properties of efficient allocations of resources and of the shadow prices that would decentralize such allocations we show in particular that the representative agent has a decreasing discount rate when as is usually posited all of a group s members have a constant discount rate and decreasing absolute risk aversion preferences we also identify conditions that lead the representative agent to have a rate of impatience that decreases with gross domestic product per capita

the permanent income hypothesis estimation and testing by instrumental variables the permanent income hypothesis with rational expectation is restated estimated and tested by an instrumental variables technique on the postwar u s aggregate time series data the hypothesis is accepted on a consumption series which includes service flows from consumer durables if the consumption series is the one in the national income and product accounts the hypothesis is decisively rejected an explanation is suggested to reconcile the conflicting test results

emergence of new economics energy transition models a review abstract well known academic and non academic institutions call for a new approach in economics able to capture features of modern economies including but not limited to complexity non equilibrium and uncertainty in this paper we provide a systematic review of ecological macroeconomic models that are suitable for the investigation of low carbon energy transitions and assess them based on the features considered desirable for a new approach in economics we draw two main conclusions firstly the knowledge base and structure of these existing ecological macroeconomic models are relevant alongside other types of models for the creation of a new approach in economics secondly the reviewed models are policy relevant especially in the context of the complexity and urgency of rapid energy transitions where increasingly policymakers require economic models able to capture real world characteristics however further improvements are needed to these models and future research should focus on i assuring comparability of models results and their policy insights ii incorporation of the relationships between macroeconomics finance and sustainability and iii the institutionalization of a new approach in economics

rethinking macroeconomics what failed and how to repair it the standard macroeconomic models have failed by all the most important tests of scientific theory they did not predict that the financial crisis would happen and when it did they understated its effects monetary authorities allowed bubbles to grow and focused on keeping inflation low partly because the standard models suggested that low inflation was necessary and almost sufficient for efficiency and growth after the crisis broke policymakers relying on the models floundered notwithstanding the diversity of macroeconomics the sum of these failures points to the need for a fundamental re examination of the models and a reassertion of the lessons of modern general equilibrium theory that were seemingly forgotten in the years leading up to the crisis this paper first describes the failures of the standard models in broad terms and then develops the economics of deep downturns and shows that such downturns are endogenous further the paper argues that there have been systemic changes to the structure of the economy that made the economy more vulnerable to crisis contrary to what the standard models argued finally the paper contrasts the policy implications of our framework with those of the standard models

expenditure on durable goods a case for slow adjustment for more than a half a decade the fact that expenditure on durables can be well approximated by a random walk has remained a hidden puzzle challenging almost any theory in which agents smooth the use of their wealth this paper shows that once a nonparsimonious approach is used or lower frequencies of the data are examined the fact itself disappears changes in expenditures on durables reveal a degree of reversion consistent with the permanent income hypothesis pih although this reversion occurs at a rate significantly slower than what is suggested by a frictionless pih model

uncertainty and the employment dynamics of small and large businesses we examine the impact of uncertainty on employment dynamics alternative measures of uncertainty are constructed based on the survey of professional forecasters and regression based forecasting models for gdp growth inflation sp the impact on large businesses are generally non existent or weaker our results suggest that to truly understand the effects of uncertainty on employment dynamics we need to focus on the relatively smaller and entrepreneurial businesses we discuss implications for the framing of economic policy

the pandemic economic crisis precautionary behavior and mobility constraints an application of the dynamic disequilibrium model with randomness this article analyzes the economic impact of the pandemic providing insights into the consequences of alternative policies our framework focuses on three key features i covid 19 is a sectoral shock of unknown depth and duration affecting some sectors and technologies more than others ii there are constraints in shifting resources across sectors and iii there is a high level of uncertainty about the disease and its economic aftermath inducing a high level of precautionary behavior by some agents and leading to others facing more severe credit constraints because of macroeconomic externalities precautionary behavior exacerbates the downturn and even sectors where covid 19 does not directly affect consumption or production may face unemployment multipliers associated with different government expenditure programs differ markedly the article describes policies that can mitigate precautionary behavior leading to reduced unemployment greater wage flexibility may lead to increased unemployment the precautionary behavior is the antithesis of equilibrium behavior suggesting that standard equilibrium approaches may not provide the appropriate framework for analyzing the pandemic individuals know that they don t know the future that existing and newly made contracts and plans may be broken and that they need to be able to respond to these unknowable contingencies

a theory of the consumption function with and without liquidity constraints fifteen years ago milton friedman s 1957 treatise a theory of the consumption function seemed badly dated dynamic optimization theory had not been employed much in economics when friedman wrote and utility theory was still comparatively primitive so his statement of the permanent income hypothesis never actually specified a formal mathematical model of behavior derived explicitly from utility maximization instead friedman relied at crucial points on intuition and verbal descriptions of behavior although these descriptions sounded plausible when other economists subsequently found multiperiod maximizing models that could be solved explicitly the implications of those models differed sharply from friedman s intuitive description of his model furthermore empirical tests in the 1970s and 1980s often rejected these rigorous versions of the permanent income hypothesis in favor of an alternative hypothesis that many households simply spent all of their current income today with the benefit of a further round of mathematical and computational advances friedman s 1957 original analysis looks more prescient than primitive it turns out that when there is meaningful uncertainty in future labor income the optimal behavior of moderately impatient consumers is much better described by friedman s original statement of the permanent income hypothesis than by the later explicit maximizing versions furthermore in a remarkable irony much of the empirical evidence that rejected the permanent income hypothesis as specified in tests of the 1970s and 1980s is actually consistent both with friedman s original description of the model and with the new version with serious uncertainty there are four key differences between the explicit maximizing models

globalisation and government spending evidence for the hyper globalisation of the 1990s and 2000s in this paper we provide an up to date empirical assessment of the relationship between economic globalisation and government spending for the hyper globalisation period of the 1990s and 2000s we use data on government consumption spending and more disaggregated spending components e g social welfare we also use a range of globalisation measures including the most recent version of the kof globalisation index and a combination of econometric methods including fixed effects and instrumental variable iv estimation the results suggest that hyper globalisation has had divergent and conflicting effects on consumption spending while de jure trade globalisation has tended to raise spending de jure financial globalisation has tended to reduce it we also find evidence that the positive effect of de facto trade globalisation on spending weakened significantly during the 1990s and 2000s in comparison with earlier decades these effects could have contributed to the growing political backlash witnessed against globalisation since the early 2000s

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

effects of transitory consumption and temporal aggregation on the permanent income hypothesis this paper shows that u s monthly consumption data are consistent with the permanent income hypothesis when transitory consumption and temporal aggregation effects are jointly incorporated into the model in this case a more appropriate representation for the permanent income hypothesis is the integrated moving average ima 1 1 process with a negative ma coefficient rather than the repeatedly rejected random walk process restrictions on the relative importance of transitory and permanent consumption are also discussed with and without measurement errors copyright 1993 by mit press

temporal aggregation and hall s model of consumption behaviour a simple exercise of time series analysis shows that the presence of the phonomenon of temporal aggregation in quarterly consumption data can substantially alter the empirical inference about hall mocel of consumption behaviour this fact has received almost no attention in the econometric research in this field

where modern macroeconomics went wrong this paper provides a critique of the dsge models that have come to dominate macroeconomics during the past quarter century it argues that at the heart of the failure were the wrong microfoundations which failed to incorporate key aspects of economic behaviour e g incorporating insights from information economics and behavioural economics inadequate modelling of the financial sector meant they were ill suited for predicting or responding to a financial crisis and a reliance on representative agent models meant they were ill suited for analysing either the role of distribution in fluctuations and crises or the consequences of fluctuations on inequality the paper proposes alternative benchmark models that may be more useful both in understanding deep downturns and responding to them

risk and global economic architecture why full financial integration may be undesirable integration of global financial markets was supposed to lead to greater financial stability as risks were spread around the world the finan cial crisis has thrown doubt on this conclusion a failure in one part of the global economic system caused a global meltdown the recent crisis has shown that in the absence of appro priate government intervention privately profit able transactions may lead to systemic risk this paper provides a general analytic framework within which we can analyze the optimal degree and form of financial integration within this general framework full integration is not in general optimal indeed faced with a choice between two polar regimes full integration or autarky in the simplified model autarky may be superior

imperfect information credit markets and unemployment this paper describes how imperfect information in both capital and labor markets can in a context of maximizing firms and perfectly flexible prices and wages give rise to cyclical variations in unemployment whose character closely resembles that of observed business cycles this abstract was borrowed from another version of this item

stochastic life cycle theory with varying interest rates and prices incorporating the assumption of rational expectations has produced some striking new predictions from many familiar economic theories one of the benefits of this development is that these new predictions provide additional means of testing well documented theories without necessarily requiring new data though it must be admitted that this is at the cost of an additional and for many a controversial assumption in his paper on life cycle and permanent income theory hall 1978 has given a very good example of such new predictions he demonstrated that if consumers are assumed to measure wealth using rational expectations of future income rather than a distributed lag of past income then a logical consequence of standard life cycle theory is that consumption will closely follow a first order autoregression subsequently bilson 1980 and flavin 1981 showed that the disturbance term in this autoregression will depend on the errors in predicting current and future income at first sight this remarkable result may seem to be inconsistent with the standard consumption function which relates consumption to income but an example will help explain why there is no necessary conflict consider the simple consumption function or absolute income hypothesis

externalities in economies with imperfect information and incomplete markets this paper presents a simple general framework for analyzing externalities in economies with incomplete markets and imperfect infonnation by identifying the pecuniary effects of these externalities that net out the paper simplifies the problem of determining when tax interventions are pareto improving the approach indicates that such tax interventions almost always exist and that equilibria in situations of imperfect information are rarely constrained pareto optima it can also lead to simple tests based on readily observable indicators of the efficacy of particular tax policies in situations involving adverse selection signaling moral hazard incomplete contingent claims markets and queue rationing equilibria traditional discussions of externalities have emphasized the distinction between technological externalities in which the action of one individual or firm directly affects the utility or profit ofanother and pecuniary externalities in which one individual s or firm s actions affect another only through effects on prices while the presence of technological externalities imply in general that a competitive equilibrium may not be pareto efficient pecuniary externalities hy themselves are not a source of inefficiency the fact that prices change has of course important consequences there are both distributional and allocational effects but the distribution effects net out gains for example hy firms whose prices increase are precisely offset by losses e g to individuals who must pay higher prices and there are no welfare losses from the allocation effects as long as the price changes involved are small if firms are maximizing profits and individuals are maximizing utility both facing prices that correctly refiect opportunity costs then standard envelope theorem arguments imply that changes in profits or utility induced by changes in allocations resulting from any small change in prices are negligible

liaisons dangereuses increasing connectivity risk sharing and systemic risk the recent financial crisis poses the challenge to understand how systemic risk arises endogenously and what architecture can make the financial system more resilient to global crises this paper shows that a financial network can be most resilient for intermediate levels of risk diversification and not when this is maximal as generally thought so far this finding holds in the presence of the financial accelerator i e when negative variations in the financial robustness of an agent tend to persist in time because they have adverse effects on the agent s subsequent performance through the reaction of the agent s counterparties 2012 elsevier b v all rights reserved

toward a theory of rigidities this paper presents a theory of rigidity or more properly inertia in the responses of economic variables to changing environments the theory rests on three fundamental assumptions 1 that firms are risk averse 2 that firms are uncertain of the impacts of changing decision variables and 3 that this uncertainty increases with the size of deviations in decision variables from appropriately defined past level under these circumstances an optimal portfolio of incremental decision variable adjustments exists which a takes variance minimizing adoptions to environmental change as a point of departure and then b is weighted in favor of changes in variables whose effects are less uncertain in considering price and quantity adjustments this implies that price and wage adjustments should largely incorporate expected inflation and from that point should be small relative to quantity adjustments since in most situations the uncertainties associated with the consequences of quantity adjustment should be smaller than those associated with price adjustments this abstract was borrowed from another version of this item

agricultural diversification into tourism evidence of a european community development programme abstract based on the empirical evidence provided by an evaluation study of the eu objective 5b programme measures for the expansion of rural tourism this article discusses the impact of rural tourism on agricultural holdings it is shown that the financial returns most often do not measure up either to the expectations of the politicians or to that of the farmers in some respects rural tourism contributes positively to the innovation of the tourist product since its small scale green issues and special facilities differentiate the product from others but the unleashing of real potential is hampered by the fact that farmers tend to give priority to traditional agriculture and by the fact that industrialized agriculture is not easily combined with the commodifying of agricultural traditions for tourism the community level inter organizational innovations which are designed to ensure the marketing and quality control of rural tourism are taking place too slowly cooperative efforts in the field of tourism are hampered by the fact that the organizations have not been logically placed in the value chain this article introduces measures to improve the inter organizational set up suggesting that this is essential if rural tourism is to be launched on any large scale

pecuniary externalities in economies with financial frictions this article characterizes the efficiency properties of competitive economies with financial constraints in which phenomena such as fire sales and financial amplification may arise we show that financial constraints lead to two distinct types of pecuniary externalities distributive externalities that arise from incomplete insurance markets and collateral externalities that arise from price dependent financial constraints for both types of externalities we identify three sufficient statistics that determine optimal taxes on financing and investment decisions to implement constrained efficient allocations we also show that fire sales and financial amplification are neither necessary nor sufficient to generate inefficient pecuniary externalities we demonstrate how to employ our framework in a number of applications whereas collateral externalities generally lead to over borrowing the distortions from distributive externalities may easily flip sign leading to either under or over borrowing both types of externalities may lead to under or over investment

dsge models still useful in policy analysis this paper discusses the usefulness of dsge models in monetary and fiscal policy analysis while the recent crisis has exposed some weaknesses in these models i argue that dsge models currently have few contenders to replace them as core models in the policy process the prominent role for forward looking behaviour and their simplicity make dsge models very suitable for policy analysis in addition dsge models are flexible enough to be used for many purposes while other models are often more limited in terms of the questions they can address as a result i argue that improved dsge models modified to take the lessons of the recent crisis into account will remain as a workhorse tool in many policy institutions for a long time to come

surprises in the consumption function the life cycle hypothesis has been the dominant theoretical basis for empirical work on the aggregate consumption function for about a quarter of a century under it real consumption is proportional to real life cycle wealth where the factor of proportionality depends on real interest rate expectations and the demographic structure of the population life cycle wealth is the sum of financial and human wealth however because the latter is the present real value of the stream of labour and transfer income expected over the life cycle it is not directly observable this fact has led to a great variety of proxying devices in empirical applications and in consequence much looseness in the interpretation of very different models as being all consistent with life cycle theory indeed one can argue that this has protected the hypothesis from being seriously tested and perhaps rejected an insight associated with friedman 1957 is that the view taken by consumers of life cycle income does not alter by much from period to period since there is greater persistence in life cycle income than in current income this also explains the greater persistence of consumption than of current income intuitively this would suggest that lagged consumption being related to last period s perception of life cycle income which in turn is not much different from this period s perception should have a major role in predicting current consumption this intuition was formalised by hall 1978 using ideas familiar from the study of stock market prices and the term structure of interest rates hall showed that if the real rate of interest is constant and given a number of other assumptions including no transitory element in consumption then the life cycle hypothesis implies that

investment decisions in manufacturing assessing the effects of real oil prices and their uncertainty summary we investigate the effects of real oil prices and their uncertainty on investment decisions making use of plant level data we estimate dynamic discrete choice models that allow modeling investment inaction under different assumptions related to initial conditions and unobserved heterogeneity we find that increases in real oil price changes and in real oil price uncertainty significantly reduce the likelihood of investment action in line with the predictions of irreversible investment theory we also document that investment decisions exhibit strong pure state dependence and are also significantly affected by initial conditions copyright 2012 john wiley sons ltd

causes and effects of financing constraints at the firm level this paper focuses on the empirical assessment of determinants and effects of financing constraints at the firm level using a standard model of credit rationing based on asymmetric information firm age and size are found to be factors which should influence the probability of financing constraints improving business conditions strengthen the degree of informational asymmetry a unique panel of firm data for germany including direct information on financing constraints is used for the econometric analysis firms size and improving business conditions are found to have a significant effect furthermore a significant impact on investment and r d expenditures cannot be rejected

financing the german mittelstand this paper describes how the german mittelstand or small and medium sized enterprises are financed in germany the role of the german mittelstand both in a static and in a dynamic framework is described and contrasted with that of the same size group in other leading industrialised countries we find that in general the mittelstand has played a mmore important role in germany than in other industrialised nations such as the united states or the united kingdom the traditional success of the german mittelstand is partly attributable to a system of finance that is richly layered by complementary institutions designed to meet the financial needs of both large and smaller enterprises however we find evidence that even under the german system of finance liquidity constraints exist and are greater for smaller firms the german system of finance moreover seems particularly deficient in the channeling of funds to new firm startups in the newer industries

does firm size matter evidence on the impact of liquidity constraints on firm investment behavior in germany abstract this paper examines the link between liquidity constraints and investment behavior for german firms of different sizes from 1970 to 1986 results indicate that medium sized firms appear to be more liquidity constrained in their investment behavior than either the smallest or largest firms in the study suggesting that the unique german infrastructure designed to assist the small firm has indeed succeeded in alleviating to some degree such liquidity constraints findings also support the hypothesis that the emerging competition and internationalism which characterized the german financial markets in the 1980s have been improving access to capital for some groups of firms

tourism farming and diversification an attitudinal study although farm based tourism has a long tradition particularly within europe farm diversification into tourism has in recent years become more widely seen as an effective means of addressing the socio economic problems of rural areas in general and the agricultural sector in particular accordingly not only has there been significant growth in the supply of farm based tourism in many countries and evidence of rural development policies supporting such growth but also increasing academic attention has been paid to the phenomenon however although a number of studies consider specific issues related to farm diversification into tourism such as marketing or financial challenges little or no research has been undertaken into the attitudes of farming families that have diversified the purpose of this paper is to address this omission in the tourism literature based on a survey of farms in north eastern england it explores farmers attitudes to a variety of issues related to diversification into tourism including the socio cultural context within which it occurs in doing so it both confirms and challenges previously held assumptions regarding the problems of diversification in particular however it identifies a widespread desire amongst farmers to maintain a distinction between the farm farming business suggesting that the development of farm tourism enterprises is an employment as opposed to diversification issue it concludes therefore that the role of public sector agencies in the support of farm tourism should be reassessed

the financial system and the natural real interest rate towards a new benchmark theory model the 2008 financial crisis revealed serious flaws in the models that macroeconomists use to research inform policy and teach graduate students in this paper we seek to find simple additions to the existing benchmark model that might let us answer three questions what caused the boom and crisis why has the recovery been slow and how should policy respond to that slow recovery we argue that it is necessary to add financial frictions to the benchmark model this allows us to study the effects of leveraged financial institutions and of a yield curve based on preferred habitats such features will cause endogenous changes in the natural real interest rate and the spread between that interest rate and the rate which influences expenditure decisions they are likely to radically change the way in which the model responds to shocks we point to some promising models that incorporate these features

toward a new microfounded macroeconomics in the wake of the crisis the great recession that followed the financial crisis of 2007 is not only the largest economic crisis after the great depression of the 1930s it also signals a crisis of economics as a discipline this is not only the consequence of the inadequacy of mainstream macroeconomics and specifically the dynamic stochastic general equilibrium dsge workhorse model to forecast such a huge event or at least to detect the worrying tendencies towards it even more relevant is the choice to explicitly avoid the modeling of large crises that for someone is a motivation for not attacking pre crisis dsge models focused on the analysis of small deviations from the steady state so denying the intrinsic nature of capitalism a system that necessarily proceeds through cycles and extended crises the replies of the dsge approach to critics have led to extensions regarding for instance the role of financial frictions heterogeneous agents and bounded rationality though typically in the form of quasi rational expectations the alternative paradigm of agent based ab macroeconomics can take into account all these elements at once within an evolutionary modeling framework based on heterogeneity and interaction so capable to endogenously reproduce complex dynamics from small fluctuations to large crises due to innovation and industrial dynamics rising inequality and financial instability and so on the integration between ab macroeconomics and the post keynesian stock flow consistent approach represents a promising way for the future development of this research field

asymmetric information and the new theory of the firm financial constraints and risk behavior this paper summarizes recent developments in the theory of the firm that have arisen in examining the implications of imperfect information it shows that a wide range of these models have similar implications for the likely reaction of firms to external environmental and policy changes two significant implications are 1 that firms behave as if they are risk averse individuals maximizing a utility function of terminal wealth profitability even when the risks involved are unsystematic and 2 in many circumstances because this utility function is likely to be characterized by decreasing absolute risk aversion firms are likely to respond significantly and positively to changes in cash flow and profitability together these two phenomena are able to account for a wide range of firm behaviors that have been empirically observed both formally and informally and that are difficult to explain in terms of the traditional theory of the firm furthermore the responses of such firms to policy interventions are likely to differ significantly from those of neoclassical firms this abstract was borrowed from another version of this item

demand uncertainty and the capital labor ratio evidence from the u s manufacturing sector richard hartman 1976 and duncan m holthausen 1976 showed that firms input choices may be affected by demand uncertainty specifically uncertain demand conditions may lead to firms operating with a lower capital ratio this result has potentially important implications for the analysis of factor demand and factor productivity the author constructs measures of demand uncertainty and examines the above relationship for a sample of 125 u s manufacturing industries results show that there exists a significant negative relationship between demand uncertainty and the capital labor ratio copyright 1991 by mit press

input choices under price uncertainty theory shows that depending on risk preferences and technological parameters price uncertainty may alter firms choice of capital intensity this paper presents an empirical analysis of the effect of price uncertainty on firms choices of capital and labor stocks empirical results from a cross section of manufacturing industries as well as within industries over time show that greater price uncertainty increases an industry s capital labor ratio it appears that risk aversion does not dominate firms decision making these empirical findings have implications for the analysis of factor demand and productivity and capacity utilization rates

small firms finance in france the data concerning interest rates paid by small and medium sized firms on credit and financial markets as well as the available balance sheets confirm the idea that firms have difficulties to get financial resources this paper tries to put in light the financial disparities among firms when a discrimination resting on size characterises the functioning of credit market the first section presents the main financial characteristics of french smes the low level of equities the heaviness of short term debts and the over use of payment delays section 2 shows how french and european authorities reacted in order to improve the financial situation of sme s and to reduce their liquidity constraint changing tax policy and promoting the creation of new means of financing

mobility constraints productivity trends and extended crises abstract in this paper we propose an interpretation of the current global financial crisis which emphasizes sectoral dislocation following localized technical change in the presence of barriers to labor mobility this tale is reminiscent of a similar tale concerning the great depression in the 30s technical change was localized in agriculture where income fell because rising productivity could not be offset by a shrinking labor force due to the costs of moving out of agriculture for unemployed workers inelastic demand for agricultural output meant that as output increased income declined as individual incomes fell below the level necessary to finance the transition to manufacturing excess labor became trapped in agriculture reducing wages and exacerbating the rise in output shrinking incomes in agriculture reverberated on the other sectors mainly manufacturing causing a large depression nowadays it is manufacturing that plays the role of epicenter of technical change falling incomes in manufacturing yield a lack of demand for goods produced in the rest of the economy namely the service sector this may be the deep rooted cause of the long lasting slump and the painfully slow recovery

is there a retirement savings puzzle in this paper we ask whether households are saving enough for their retirement we use data on income expenditure and expenditure components to analyse patterns of behaviour at and around the time of retirement for successive date of birth cohorts we compare periods of unemployment to periods of retirement and separate expenditures into categories reflecting work related expenditures basic necessities and other goods we find that income typically falls by more at unemployment than retirement but the reverse is true for expenditure we observe falls in expenditure at retirement for all expenditure categories using a stochastic life cycle model including mortality rates we assess the anticipated impact of retirement on consumption against that of unemployment the inter relationship between goods and leisure explains a large part of the persistent fall in expenditure at retirement we argue that the only way in which the life cycle hypothesis could be reconciled with the remaining unanticipated dip in consumption would be with the systematic arrival of unexpected adverse information at the time of retirement
