finite lifetimes and the effects of budget deficits on national saving abstract even though realistic deficit policies shift sizable tax burdens to future generations the assumption of an infinite horizon is a good approximation for analyzing a deficit s short run saving effect on individuals who are neither liquidity constrained nor myopic recent u s experience casts significant doubt on these assumptions however and appears difficult to reconcile with the ricardian equivalence proposition that the timing of taxes does not affect national saving recent deficits have coincided with reduced national saving and a substantial increase in the share of gnp devoted to consumption

targeted transfers and the fiscal response to the great recession abstract between 2007 and 2009 government expenditures increased rapidly across the oecd countries while economic research on the impact of government purchases has flourished in the data most of the increase in expenditures was in government transfers after documenting this fact we argue that future research should focus on the positive impact of transfers towards this we present a model in which there is no representative agent and ricardian equivalence does not hold because of uncertainty imperfect credit markets and nominal rigidities targeted lump sum transfers are expansionary both because of a neoclassical wealth effect and because of a keynesian aggregate demand effect

international differences in saving the adequacy of national saving has taken on increasing importance in an era of large external imbalances among the major industrial countries at least among economists current account imbalances are seen as largely the outcome of domestic patterns of saving and investment rather than trade practices thus the low level of saving in the united states rather than a failure of japan to open its economy is the primary cause of the u s current account deficit most of the discussion of the decline of u s saving has focused upon the emergence of a large government budget deficit in the 1980s and has largely ignored an equally large decline in an already low level of private saving at the same time much of what we think we know about private saving behavior and the potential effectiveness of various policies to influence it are dominated by experience only within our own country but many of the factors in which we are most interested have exhibited very limited historical variation within the united states and of necessity the conclusions are ambiguous the purpose of this note is to make use of an underutilized data source that provides information on the saving and investment of the industrial countries within a common accounting framework to examine the pattern of change over time and the similarity of response to various economic disturbances in the 1970s and 1980s the basic annual data are drawn from the system of national accounts sna submitted by the individual member countries to the oecd for the period 1960 87 while the original analysis was undertaken for the seven largest nations plus a representative set of six smaller countries but the summary reported here is limited to the united states japan and an aggregate of nine european countries the data are presented within a simple accounting framework that relates the current account surplus ca to the difference between domestic saving s and domestic investment i domestic saving and investment can be further subdivided into their public and private components

what stirpat tells about effects of population and affluence on the environment abstract in the literature on the application of stirpat to environmental impacts of population and affluence the parameter estimates differ from study to study one example is the effect of population size on co 2 emissions which is concluded to be very close to 1 in some studies e g york et al 2003 while far from 1 in others e g shi 2003 what can explain these differences in results in the present paper i offer an alternative model equivalent to stirpat which explicitly specifies the different role of technology t in stirpat from ipat by the alternative model i conclude that different functional forms of stirpat can be one explanation for the difference among estimates in the studies on environmental impacts of population and affluence the alternative model can also help to determine which factors to be added in stirpat

income working hours and happiness abstract in empirical analyses the effect of income on happiness tends to be underestimated by ignoring the fact that income has to be earned using the german socio economic panel our analysis confirms this tendency for men the underestimation amounts to 25

speculative growth hints from the u s economy we propose a framework for understanding episodes of vigorous economic expansion and extreme asset valuations we interpret this phenomenon as a high valuation equilibrium with a low cost of capital based on optimism about future funding the key ingredient for such equilibrium is feedback from increased growth to a decline in the long run cost of capital this feedback arises when an expansion comes with technological progress in the capital sector when fiscal rules generate procyclical fiscal surpluses when the rest of the world has lower expansion potential or high saving needs and when financial constraints are relaxed by the expansion itself

collective moral hazard maturity mismatch and systemic bailouts the paper elicits a mechanism by which private leverage choices exhibit strategic complementarities through the reaction of monetary policy when everyone engages in maturity transformation authorities haver little choice but facilitating refinancing in turn refusing to adopt a risky balance sheet lowers the return on equity the key ingredient is that monetary policy is non targeted the ex post benefits from a monetary bailout accrue in proportion to the number amount of leverage while the distortion costs are to a large extent fixed this insight has important consequences first banks choose to correlate their risk exposures second private borrowers may deliberately choose to increase their interest rate sensitivity following bad news about future needs for liquidity third optimal monetary policy is time inconsistent fourth macro prudential supervision is called for we characterize the optimal regulation which takes the form of a minimum liquidity requirement coupled with monitoring of the quality of liquid assets we establish the robustness of our insights when the set of

fiscal policy banks and the financial crisis this paper studies the effectiveness of euro area ea fiscal policy during the recent financial crisis using an estimated new keynesian model with a bank a key dimension of policy in the crisis was massive government support for banks that dimension has so far received little attention in the macroeconomics literature we use the estimated model to analyze the effects of bank asset losses of government support for banks and other fiscal stimulus measures in the ea our results suggest that support for banks had a stabilizing effect on ea output consumption and investment increased government purchases helped to stabilize output but crowded out consumption higher transfers to households had a positive impact on private consumption but a negligible effect on output and investment banking shocks and increased government spending explain half of the rise in the public debt gdp ratio since the onset of the crisis

the demand for liquid assets corporate saving and international capital flows the recent period of capital outflows from emerging economies has coincided with an increase in their corporate saving in this paper we model corporate saving as a demand for liquid assets by credit constrained firms in a dynamic open economy macroeconomic model we find that the implications of this model are very different from standard models because the demand for foreign bonds is a complement to domestic investment rather than a substitute we show that this complementarity is at work when an emerging economy is on its convergence path or when it has a higher tfp growth rate this framework is consistent with a number of stylized facts found in high growth high investment emerging economies

the fiscal multiplier in a liquidity constrained new keynesian economy we study the effects of fiscal policy on the macroeconomy using a liquidity constrained new keynesian model in which government bonds are liquid and private financial assets are only partially liquid we find that the fiscal multipliers in this economic environment are large enough for fiscal policy to be highly effective in this model a bond financed fiscal expansion can stimulate output because higher public borrowing improves liquidity by increasing the proportion of liquid assets in private sector wealth

societal metabolism working hours and degrowth a comment on sorman and giampietro can we choose whether to degrow sorman and giampetro in this special issue argue that degrowth can only be forced upon us it will never be the outcome of voluntary or collective choice in this commentary i argue instead that although sooner or later we will have to degrow because of bio physical limitations we still have a choice of how to do it constructing a positive vision of degrowth as an inspirational political project that mobilizes citizens increases the likelihood of a prosperous way down i agree with the authors that in an energy scarce world we will have to work more to maintain the same level of material affluence but i contend that under conceivable conditions we might be equally happy with less work less energy and less material affluence a multi scalar analysis of societal metabolism is essential for the evaluation of degrowth policies and trajectories however unlike what sorman and giampietro suggest there is nothing in existing metabolic analyses that suggests that a prosperous degrowth trajectory is a priori impossible

the effectiveness of government debt and transfers as insurance abstract government debt and redistributive taxation can help people to smooth consumption when facing uninsurable individual specific risk i examine the effects that variations in public debt and transfers have on risk sharing efficiency and the distribution of resources i find that risk sharing can be improved significantly by both debt and transfers but that debt has adverse effects on equity when used in isolation debt will enhance welfare if transfers are lower than optimal however the beneficial effects of public debt vanish if transfers are used optimally

the aaea ever growing and changing research challenges the changing economic conditions over the past century along with changes in technology and developments in economic theory and quantitative methods helped shape the profession we currently refer to as agricultural and applied economics the broadening of the profession from the original focus on the farm and agricultural industry to encompass international affairs governmental policies resources and environmental and rural affairs is discussed within this context emergence of the subdisciplines and some of the major individual contributions are noted the final section argues that members of the profession are well positioned to continue contributing research that will help society achieve its goals and notes six challenges that provide such opportunities

bubbles and self enforcing debt we characterize equilibria with endogenous debt constraints for a general equilibrium economy with limited commitment in which the only consequence of default is losing the ability to borrow in future periods first we show that equilibrium debt limits must satisfy a simple condition that allows agents to exactly roll over existing debt period by period second we provide an equivalence result whereby the resulting set of equilibrium allocations with self enforcing private debt is equivalent to the allocations that are sustained with unbacked public debt or rational bubbles in contrast to the classic result by bulow and rogoff 1989a positive levels of debt are sustainable in our environment because the interest rate is sufficiently low to provide repayment incentives

the when the how and the why of mathematical expression in the history of economic analysis when one reads about the history of the use of mathematical expression in economics one gets the impression of a few brave but lonely innovators like daniel bernoulli 1738 achille isnard 1781 n f canard 1801 johann von thunen 1826 and antoine augustin cournot 1838 present at the creation of economic thought and later a feisty band of visionaries associated with the marginalist revolution at the turn of the century who had the right tools in their rucksacks and then finally the full flowering of activity in the postwar period through it all there is the unmistakable conviction that this movement was cumulative inevitable and indeed natural

popular protest and political budget cycles a panel data analysis we test the hypothesis that governments facing popular protest are more likely to use fiscal policy for re election purposes employing data of 65 democratic countries both developed and developing over the period 1975 2005 using the number of anti government demonstrations and general strikes in pre election years as measures of popular protest our results lend support to this hypothesis the effect of protest on the manipulation of fiscal policy for re election purposes is strongest in young democracies

emulation inequality and work hours was thorsten veblen right we investigate the manner in which a desire to emulate the rich influences individuals allocation of time between labour and leisure greater inequality inducing longer work hours as a result data on work hours in ten countries over the period 1963 98 show that greater inequality is indeed associated longer work hours these veblen effects are large and the estimates are robust using country fixed effects and other specifications because consumption inequality is a public bad a social welfare optimum cannot be implemented by a flat tax on consumption but may be accomplished by more complicated progressive consumption taxes at the close of the nineteenth century thorsten veblen proposed what he termed pecuniary emulation as the foundation of a theory of consumption spending he maintained is driven by relative status considerations that is by the desire to be a particular type of person as much as bythedesire to enjoytheconsumer goodsper se the joneses with whom one had to keep up were not the neighbours but the rich theirleveloflivingbecamethenever attainableobjectiveinaconsumptionarmsrace among the less well to do in the theory of the leisure class he wrote the motive is emulation the stimulus of an invidious comparison especially in any community in which class distinctions are quite vague all canons and reputability and decency and all standards of consumption are traced back by insensible gradations to the usages and thoughts of the highest social and pecuniary class the wealthy leisure class 1934 p 81 while valued by some economists as capturing common sense aspects of consumption as a form of status seeking veblen s view of social preferences was soon eclipsed by the simpler and more tractable neoclassical theory of the consumer relegated to the underworld of economics veblen s ideas have nonetheless resonated over the ensuing years in the writing of duesenberry 1949 leibenstein 1950 and galbraith 1958 at the middle of the past century and schor 1998

does the worldwide shift of fdi from manufacturing to services accelerate economic growth a gmm estimation study abstract we examine the effect of manufacturing and service fdi foreign direct investment on their own sector growth the spillover to the other sectors and the overall economy in host countries we identify significant sectoral and inter industry spillover effects with various data classifications and types of fdi flows evidence reveals that growth effect of manufacturing fdi operates by stimulating activity in its own manufacturing sector and is prevalent in latin america caribbean in europe central asia middle to low income countries and economies with large industry share a surge of service fdi is likely to spur growth in service industries but hurt activity in manufacturing industries financial service fdi enhances growth in south east asia and the pacific high income countries and service based economies by stimulating activity in both manufacturing and service sectors however nonfinancial service fdi drains resources and hurts manufacturing industry in the same group of countries we conclude that a shift from manufacturing to service fdi is likely to lead to deindustrialization in certain regions and types of economies if this shift is spearheaded by nonfinancial fdi

sustainable development challenges to profession of agricultural economics fundamentally sustainable development is a notion of discipline disciplining our current consumption this sense of intergenerational responsibility is a new political principle a virtue that must now guide economic growth the industrial world has already used so much of the planet s ecological capital that the sustainability of future life is in doubt that can t continue brundtland page 5

the ricardian approach to budget deficits persistent budget deficits have increased economists interest in theories and evidence about fiscal policy this paper develops the ricardian approach and contrasts it with standard models the discussion considers from major theoretical objections to ricardian equivalence finite lifetimes imperfect capital markets uncertainty about future taxes and incomes and the distorting effects of taxation the paper then considers empirical evidence on interest rates consumption and saving and current account deficits the conclusion is that the ricardian approach is a useful first order approximation and that this approach will probably become the benchmark model for assessing fiscal policy this abstract was borrowed from another version of this item

household work and energy consumption a degrowth perspective catalonia s case study the present work contributes to bringing visibility to the part of social work that is referred to as unpaid work this part of social work remains outside the market but it is necessary to structure and maintain households human relationships and communities and providing sustenance and care it represents a flow of hidden subsidies to the economy mostly shaped structured and experienced by women through an explorative case study in catalonia we relate the use of time in catalan society with the relative consumption of energy this research strategy allows us to see the dangers of substituting labour and skills from household based production to the commodity based economy in terms of an increase in energy demand in a context of the end of cheap oil on the contrary from a degrowth perspective we argue that the future adaptability might require policies reallocating resources towards the unpaid and the community

public debt under limited private credit there is a conventional wisdom in economics that public debt can serve as a substitute for private credit if private borrowing is limited the purpose of this paper is to show that while a government could in principle use such a policy to fully relax borrowing limits this is not generally optimal in our economy agents invest in a short term asset a long term asset and government bonds agents are subject to idiosyncratic liquidity shocks prior to the maturity of the long term asset we show that a high public debt policy fully relaxes private borrowing limits and is suboptimal this is because agents expecting such a policy respond by investing less than is socially optimal in the short asset which can protect them in the event of a liquidity shock the optimal policy is more constrained and it induces a wedge between the technological rate of return on the long asset and the rate of return on bonds in such a regime agents subject to liquidity shocks are also borrowing constrained and this expectation of being borrowing constrained induces them to invest the optimal level in the short asset jel h63 e62 g20

working time reduction policy in a sustainable economy criteria and options for its design abstract reducing per capita consumption particularly amongst high income groups is often deemed necessary to reduce the environmental impacts of the global economy far from implying a necessary reduction in wellbeing some research suggests this could actually improve it as reduced expenditure means a reduced need for income and hence paid work then there is the possibility for average working hours to fall providing increased leisure time in which to pursue happiness through less consumption intensive but more time consuming ways to date however there has been little critical discussion of the details of what policy might need to cover to allow and encourage substantial working time reduction in a way that successfully reconciles these environmental and wellbeing goals this article addresses this gap in the literature it begins by reviewing the conditions under which working time reduction could bring environmental and wellbeing benefits it then presents examples of innovative voluntary working time policies from the netherlands and belgium drawing these elements together the article presents a new green life course approach for working time policy design it argues that as a complement to more conventional working time policies this could be a valuable tool to combine environmental and wellbeing goals

asset prices debt constraints and inefficiency abstract we consider possibly non stationary economies with endogenous solvency constraints under uncertainty over an infinite horizon as in alvarez and jermann 2000 5 a sort of cass criterion cass 1972 10 completely characterizes constrained inefficiency under the hypothesis of uniform gains from risk sharing which is always satisfied in stationary economies when the autarchy is constrained inefficient uniform gains from risk sharing also guarantee a finite value of the intertemporal aggregate endowment at a constrained optimum hence no equilibrium exhibits a null interest rate in the long run finally constrained inefficiency occurs if and only if there exists a feasible redistribution producing a welfare improvement at all contingencies

does environmental pollution affect labor supply an empirical analysis based on 112 cities in china abstract recently some white collar workers in heavily polluted cities in china have begun to either demand higher payment due to serious air pollution or even flee the cities in this study the influence of urban pollution on labor supply is explored for the first time given that pollution and employment occur mainly in urban areas a city level panel data set consisting of 112 chinese cities from 2002 to 2013 is utilized to account for the spatial correlations of pollution a spatial factor that measures the influences of neighboring cities pollution is incorporated to deal with potential endogeneity and to ensure robust estimations the generalized method of moments and piece wise panel regression methods are utilized the estimation results indicate that the impact of pollution on labor supply is nonlinear as the environmental quality deteriorates the labor supply will increase at first and then decrease after the peak is reached moreover income level also affects the impact of air pollution on labor supply at a given pollution level the higher the average income the fewer people will work in the city the spatial correlation is verified to be significantly negative suggesting that air pollution in nearby areas has detrimental impacts on the local labor supply

monetary policy product market competition and growth in this paper we argue that monetary easing fosters growth more in more credit constrained environments and the more so the higher the degree of product market competition indeed when competition is low large rents allow firms to stay on the market and reinvest optimally no matter how funding conditions change with aggregate conditions to test this prediction we use industrylevel and firm level data from the euro area to look at the effects on sectoral growth and firm level growth of the unexpected drop in long term government bond yields following the announcement of the outright monetary transactions program omt by the ecb we find that the monetary policy easing induced by omt contributed to raising sectoral firm level growth more in more highly leveraged sectors firms and the more so the higher the degree of product market competition in the country sector

economic growth with bubbles this paper presents a stylized model of economic growth with bubbles this model views asset price bubbles as a market generated device to moderate the effects of frictions in financial markets improving the allocation of investments and raising the capital stock and welfare the model illustrates various channels through which asset price bubbles affect the incentives for innovation and economic reforms and therefore the rate of economic growth the model also offers a new perspective on the effects of financial development on asset price bubbles and economic growth

y2k options and the liquidity premium in treasury markets financial institutions around the world expected the millennium date change y2k to cause an aggregate liquidity shortage responding to the concern the federal reserve bank of new york auctioned y2k options to primary dealers the options gave the dealers the right to borrow from the fed at a predetermined interest rate using the implied volatilities of y2k options and the on off the run spread we demonstrate that the fed s action eased the fears of bond dealers contributing to a drop in the liquidity premium of treasury securities our analysis shows the link between the microstructure of government debt markets and the central bank s provision of liquidity we argue that y2k options and their effects on liquidity premium broadly conform to the economic theory on public provision of private liquidity

budget deficits rhetoric and reality w v t hatever the real or imagined ills of the economy the news media most politicians and a fair proportion of the economics profession are quick to point to the culprit the budget deficit no matter that few appear to know or care precisely what deficit they are talking about or how it is measured no matter that few bother to explain in terms of a relevant model just how government deficits may be expected to impact the economy no matter that few offer any empirical data to sustain their judgments so budget deficits cause inflation budget deficits raise interest rates budget deficits bring on the trade deficits budget deficits crowd out investment budget deficits are an irresponsible mortgage on the future and budget deficits caused the october 1987 stock market crash and now threaten further financial cataclysms is there truth in any of these assertions or does it all depend budget deficits do matter and their effects contrary to barro s ricardian equivalence theorem can be substantial as most economists have recognized for at least half a century budget deficits can however be too small as well as too large to know which you have to measure them right and you have to analyze their role in the world in which we live pure walrasian and rational expectation market clearing models may prove more useful for academic advancement than for promotion of economic health i need not repeat many of the objections to the equivalence theorem raised by bernheim and gramlich and addressed by barro in this symposium however there is

the optimal public and private provision of safe assets abstract we develop a theory of optimal government debt in which publicly issued and privately issued safe assets are substitutes while government bonds are backed by future tax revenues privately issued safe assets are backed by the future repayment of pools of defaultable private loans we find that a higher supply of public debt crowds out privately issued safe assets less than one for one and reduces the interest spread between borrowing and deposit rates our main result is that the optimal level of public debt does not fully crowd out private lending and maintains a positive interest spread moreover the optimal level of public debt is higher the more severe are financial frictions

missing carbon reductions exploring rebound and backfire effects in uk households households are expected to play a pivotal role in reducing the uk s greenhouse gas ghg emissions and the uk government is encouraging specific household actions to help meet its targets however due to the rebound effect only a portion of the ghg emission reductions estimated by simple engineering calculations are generally achieved in practice for example replacing short car journeys by walking or cycling reduces consumption of motor fuels but this frees up money that may be spent on for example purchasing extra clothes or flying on vacation alternatively the money may be put into savings since all of these options lead to ghg emissions total ghg savings may be less than anticipated indeed in some instances emissions may increase a phenomenon known as backfire we estimate that the rebound effect for a combination of three abatement actions by uk households is approximately 34 targeting re spending on goods and services with a low ghg intensity reduces this to a minimum of around 12 while re spending on goods and services with a high ghg intensity leads to backfire our study highlights the importance of shifting consumption to lower ghg intensive categories and investing in low carbon investments

estimating the impact of welfare programs on agricultural output evidence from india rural welfare programs are implemented for a variety of reasons however of key importance is to understand how government spending under such programs affects local agricultural output which is a key measure of economic activity in developing economies this article estimates the local multiplicative effects of transfer spending by the government using a novel data set of state level expenditure under rural welfare programs in india using government records as narrative evidence i use the motivation to implement new programs at the national level to construct changes in transfer spending that are largely exogenous to fluctuations in agricultural output at the state level i estimate local multipliers using this narrative shock series and find government transfers to be quite consequential for local economic activity

impact caps why population affluence and technology strategies should be abandoned abstract this paper classifies strategies to reduce environmental impact according to the terms of the i pat formula policies limiting resource depletion and pollution impact by heavily taxing resources or rationing them on a country basis are thus called direct or left side strategies other policies to achieve the environmental goal of lowering impact strive to limit population and affluence or to use technology to lower the ratio of resource inputs to goods and services outputs next it is shown that lowering any of these right side factors causes or at least enables the other two to rise or rebound this has two consequences 1 since i pat does not express these interdependencies on the right side it is more accurately written i f p a t and 2 success in lowering any of the right side factors does not necessarily lower impact rationing or pigouvian taxation of resources or pollution on the other hand necessarily lower impact and are therefore preferable to population consumption and technological environmental strategies finally lifestyle and technology changes towards more sufficiency and efficiency would follow the caps as consumers and producers work to retain the greatest amount of welfare within the limits given

happy degrowth through more amateur economy abstract this paper outlines a simple aggregate descriptive model of what is here termed a whole economy covering all human involvement in the economy from ultimate means or ecological sacrifices to the ultimate ends of human satisfaction the model embraces not only the formal professional economy driven by money but also the parallel non paid voluntary economy here termed amateur economy driven by peoples affective motivations the input of work to the economy plays an essential role in the paper s analysis of options for reducing ecological sacrifices hence part of the paper is devoted to a brief historical overview of the role of work including turning points in the 1930s in the united states when work sharing was displaced by work creation through consumerism and in the post war economy when gdp became the dominant economic indicator the paper proposes the aim of a happy and sustainable degrowth for affluent countries implying the transfer of some activities from the professional economy to the less labor productive amateur economy this will tend to reduce overall labor productivity and hence resource throughput but increase satisfaction and happiness a key element in the analysis is combining a reduction in consumption with a reduction in production which is obtainable through lowering either working time or work productivity and turning some of the leisure time into voluntary activities economic growth is not a law of nature but the consequence of explicit political decisions taken hence growth is also open to new political decisions in recognition of physical limits to growth and the human quest for replacing economic growth with life satisfaction including increased free time

a note on optimal fiscal policy in an economy with private borrowing limits abstract we consider the implications for optimal fiscal policy when taxes are non distortionary and households are heterogeneous and borrowing constrained the main result is that optimal policy keeps some households borrowing constrained in order to reduce interest rates on government debt

volatility and growth credit constraints and the composition of investment abstract how does uncertainty and credit constraints affect the cyclical composition of investment and thereby volatility and growth this paper addresses this question within a model where firms engage in two types of investment a short term one and a long term one which contributes more to productivity growth because it takes longer to complete long term investment has a relatively less cyclical return but it also has a higher liquidity risk the first effect ensures that the share of long term investment to total investment is countercyclical when financial markets are perfect the second implies that this share may turn procyclical when firms face tight credit constraints a novel propagation mechanism thus emerges through its effect on the cyclical composition of investment tighter credit can lead to both higher volatility and lower mean growth evidence from a panel of countries provides support for the model s key predictions

the incidence of deficit finance with imperfect capital markets the purpose of this paper is to examine the possible differential welfare implications of deficit finance using a portfolio allocation model to analyze the incidence of changing the time path of taxation in an economy with heterogeneous agents i develop a two period general equilibrium extension of work done previously to analyze the effects of taxation on risk taking at the individual level constraints on short sales of assets are introduced and fiscal policy changing the timing of taxation will indirectly determine which of these constraints bind as well as alter relative tax burdens changes in the timing of a flat rate tax will also alter equilibrium asset returns and because preferences are such that agents differ in their tolerance of risk a pareto frontier can be derived over a range of different levels of deficit finance

monetary fiscal interactions with endogenous liquidity frictions i develop a tractable macro model with endogenous asset liquidity to understand monetary fiscal interactions with liquidity frictions agents face idiosyncratic investment risks and meet financial intermediaries in competitive search markets asset liquidity is determined by the search friction and the cost of operating the financial intermediaries and it drives the financing constraints of entrepreneurs those who have investment projects and their ability to invest in contrast to private assets government bonds are fully liquid and can be accumulated in anticipation of future opportunities to invest a higher level of real government debt enhances the liquidity of entrepreneurs portfolios and raises investment however the issuance of debt also raises the cost of financing government expenditures a higher level of distortionary taxation and or a higher real interest rate a long run optimal supply of government debt emerges i also show that a proper mix of monetary and fiscal policies can avoid a deep financial recession

institutional causes macroeconomic symptoms volatility crises and growth countries that have pursued distortionary macroeconomic policies including high inflation large budget deficits and misaligned exchange rates appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period does this reflect the causal effect of these macroeconomic policies on economic outcomes one reason to suspect that the answer may be no is that countries pursuing poor macroeconomic policies also have weak institutions including political institutions that do not constrain politicians and political elites ineffective enforcement of property rights for investors widespread corruption and a high degree of political instability this paper documents that countries that inherited more extractive institutions from their colonial past were more likely to experience high volatility and economic crises during the postwar period more specifically societies where european colonists faced high mortality rates more than 100 years ago are much more volatile and prone to crises based on our previous work we interpret this relationship as due to the causal effect of institutions on economic outcomes europeans did not settle and were more likely to set up extractive institutions in areas where they faced high mortality once we control for the effect of institutions macroeconomic policies appear to have only a minor impact on volatility and crises this suggests that distortionary macroeconomic policies are more likely to be symptoms of underlying institutional problems rather than the main causes of economic

fiscal policy in a tractable liquidity constrained economy we analyse the effects of fiscal expansions when public debt is used as liquidity by the private sector aggregate shocks are introduced into an incomplete market economy where heterogenous agents face occasionally binding borrowing constraints and store wealth to smooth out idiosyncratic income fluctuations debt financed increases in spending facilitate self insurance by bond holders and may crowd in private consumption they also loosen the borrowing constraints faced by firms thereby raising labour demand and possibly the real wage whether private consumption and wages rise or fall ultimately depends on the relative strengths of the liquidity and wealth effects that arise following the shock

the employment effects of credit market disruptions firm level evidence from the 2008 9 financial crisis this article investigates the effect of bank lending frictions on employment outcomes i construct a new data set that combines information on banking relationships and employment at 2 000 nonfinancial firms during the 2008 9 crisis the article first verifies empirically the importance of banking relationships which imply a cost to borrowers who switch lenders i then use the dispersion in lender health following the lehman crisis as a source of exogenous variation in the availability of credit to borrowers i find that credit matters firms that had precrisis relationships with less healthy lenders had a lower likelihood of obtaining a loan following the lehman bankruptcy paid a higher interest rate if they did borrow and reduced employment by more compared to precrisis clients of healthier lenders consistent with frictions deriving from asymmetric information the effects vary by firm type lender health has an economically and statistically significant effect on employment at small and medium firms but the data cannot reject the hypothesis of no effect at the largest or most transparent firms abstracting from general equilibrium effects i find that the withdrawal of credit accounts for between one third and one half of the employment decline at small and medium firms in the sample in the year

on the interplay between speculative bubbles and productive investment the aim of this paper is to study the interplay between long term productive investments and more short term and liquid speculative ones a three period lived overlapping generations model allows us to make this distinction agents have a portfolio decision when young they can invest in human capital that is a productive long term investment that provides a return during the following two periods when young or in the middle age they can invest in a bubble young individuals can also borrow on a credit market to finance the productive investment however the amount borrowed is limited by a credit constraint we show that the existence of a stationary bubble raises productive investment and production when the bubleless economy is credit constrained and dynamically efficient indeed young agents sell short the bubble to increase productive investments whereas traders at middle age transfer wealth to old age the bubble allows to relax the credit constraint we outline that a permanent technological shock inducing either a larger return of capital in the short term or a similar increase in the return of capital in both periods raises productive capital production and the bubble size we use our framework to discuss the effect on the occurrence of bubbles of financial regulation and fiscal policy

public versus private provision of liquidity is there a trade off abstract to what extent is public debt private liquidity much policy advice given in the aftermath of the financial crisis rests on the assumption that increasing public debt relaxes borrowing constraints of private households this is the case for ad hoc debt limits which are exogenous to public policy instead if debt limits are fully endogenous as e g in the case of the natural borrowing limit public debt has no impact we assume that borrowing limits arise because of limited contract enforceability and are therefore determined as equilibrium outcomes using an incomplete markets economy in which households are subject to uninsurable earnings shocks we show that public debt provides some liquidity but less so than it would if constraints were imposed ad hoc we show that generating borrowing constraints as an equilibrium outcome substantially alters the answers to other important questions such as for the welfare effects of government debt or its impact on real economic activity

does decreasing working time reduce environmental pressures new evidence based on dynamic panel approach abstract there is a growing interest in the correlation between working time and environmental pressures but prior empirical studies were mostly focused on static methods within limited country groups to fill the gap this study aims to stimulate the discussion by distinguishing between different time periods for developed and developing country groups respectively in particular we contribute to a further understanding of the environmental effects of working time reduction policies by comparing the differences under the dynamic framework of system generalized method of moments we applied this dynamic panel regression approach for 55 countries worldwide over the period 1980 2010 and employing carbon emissions per capita as the environmental indicator in general results confirmed the significant relationship between hours of work and environmental impacts in developed economies although this is not the case for the developing counterparts interestingly the significant correlations for the developed country group turned from positive during the first sub period 1980 2000 to negative during the second sub period 2001 2010 connecting these results with previous literature we proposed the reasons of rebound energy use derived from certain leisure activities which were more energy intensive if excessive non working time provided

fiscal policy with heterogeneous agents and incomplete markets i undertake a quantitative investigation into the short run effects of changes in the timing of proportional income taxes for model economies in which heterogeneous households face a borrowing constraint temporary tax changes are found to have large real effects in the benchmark model a temporary tax cut increases aggregate consumption on impact by around 29 cents for every dollar of tax revenue lost comparing the benchmark incomplete markets model to a complete markets economy income tax cuts provide a larger boost to consumption and a smaller investment stimulus when asset markets are incomplete copyright 2005 wiley blackwell

short time work some long run implications this paper outlines a simple model to examine some long run implications of short time work schemes stws on labor market performance and welfare it is not clear that stws reduce unemployment as the induced wage push discourages job creation

money with idiosyncratic uninsurable returns to capital abstract this paper extends the income fluctuations problem to an economy with endogenous growth individuals instead of owning a stream of endowments accumulate capital with an investment irreversibility constraint and face uninsurable idiosyncratic risks to the return to capital money provides both a risk diversification and a liquidity role balanced growth paths exist despite the increasing dispersion of the wealth distribution the return to money cannot be equated to the social return to capital unless the government owns the entire capital stock with idiosyncratic risk and it is capable of operating this stock as efficiently as private agents can journal of economic literature classification numbers e31 e42 e58

where ricardo and mill rebut and confirm arguments of mainstream economists supporting globalization most noneconomists are fearful when an emerging china or india helped by their still low real wage rates outsourcing and miracle export led developments cause layoffs from good american jobs this is a hot issue now and in the coming decade it will not go away prominent and competent mainstream economists enter into the debate to educate and correct warm hearted protestors who are against globalization here is a fair paraphrase of the argumentation that has been used recently by alan greenspan jagdish bhagwati gregory mankiw douglas irwin and economists john or jane doe spread widely throughout academia yes good jobs may be lost here in the short run but still total u s net national product must by the economic laws of comparative advantage be raised in the long run and in china too the gains of the winners from free trade properly measured work out to exceed the losses of the losers this is not by mysterious fuzzy magic but rather comes from a sharing of the trade induced rise in total global vectors of the goods and services that people in a democracy want never forget to tally the real gains of consumers alongside admitted possible losses of some producers in this working out of what schumpeter called creative capitalist destruction correct economic law recognizes that some american groups can be hurt by dynamic free trade but correct economic law vindicates the word creative destruction by its proof sic that the gains of the american winners are big enough to more than compensate the losers

debt nonneutrality policy interactions and macroeconomic stability we study the consequences of non neutrality of government debt for macroeconomic stabilization policy in an environment where prices are sticky assuming transaction services of government bonds ricardian equivalence fails because public debt has a negative impact on its marginal rate of return and thus on private savings stability of equilibrium sequences requires a stationary evolution of real public debt which steers inflation expectations and rules out endogenous fluctuations under anti inflationary monetary policy regimes macroeconomic fluctuations tend to decrease with the share of tax financing which justifies tight debt constraints in particular a balanced budget policy stabilizes the economy under cost push shocks such that output and inflation variances can be lower than in a corresponding case where debt is neutral

asset bubbles endogenous growth and financial frictions this paper analyzes the effects of bubbles in an infinitely lived agent model of endogenous growth with financial frictions and heterogeneous agents we provide a complete characterization on the relationship between financial frictions and the existence of bubbles our model predicts that if the degree of pledgeability is sufficiently high or sufficiently low bubbles can not exist they can only arise at an intermediate degree this suggests that improving the financial market condition might enhance the possibility of bubbles we also examine whether bubbles are growth enhancing or growth impairing in the long run we show that when the degree of pledgeability is relatively low bubbles boost long run growth on the other hand when it is relatively high bubbles lower long run growth moreover we examine the effects of the burst of bubbles and show that the effects much depend on the degree of the pldgeability i e the quality of financial system

sustainable growth criteria minimum benchmarks and scenarios for employment and the environment abstract the relationship of economic growth and environmental impact has spurred fierce debates between growth optimists referring to the phenomenon of the environmental kuznets curve and pessimists referring to the limits to growth however no operational set of simple criteria has been developed so far to assess the sustainability of a given growth pattern this is all the more true for measures combining environmental and social criteria the paper undertakes to sketch out such criteria and to assess them by applying them to transdiciplinary sustainability scenarios and model simulations with panta rhei one of the most complex models of the german economy theoretical considerations as well as the empirical work with the model demonstrate that there are indeed trade offs between economic growth and environmental impacts and a positive correlation of growth and employment nonetheless it is still possible to develop carefully orchestrated strategies that combine economic competitiveness low unemployment rates and an easing of the pressure on the environment social and technical innovation reduced working time a modernised social security system green taxes and salary increases proportional to labour productivity growth are essential parts of any such strategy the triple effectiveness of such strategies regarding environmental social and economic sustainability is demonstrated by the model runs

growth degrowth and climate change a scenario analysis article i nfo article history the paper proceeds with a discussion of the interplay of scale and intensity in determining greenhouse gas emissions this is followed by the presentation of several macroeconomic scenarios using lowgrow a simulation model of the canadian economy the scenarios considered are business as usual which is a projection into the future of past trends selective growth in which differential growth rates are applied to parts of the economy according to their direct and indirect greenhouse gas emissions and degrowth where the average gdp capita of canadians is reduced towards a level more consistent with a world economy the size of which respects global environmental limits the paper ends with a comparison of the scenarios 2011 published by elsevier b v

working time regulation in france from 1996 to 2012 france which is often seen as an unusual country with a rigid 35 hour working week has experienced massive changes in its regulation of working time in recent decades including a progressive removal of 35 hour working week laws these changes have affected and continue to affect workplace organisation working conditions job creation productivity and wages the 35 hour working week policy represents a reduction in working time as well as a complex package that restructured french labour law and that opened up a great deal of space for social bargaining this paper provides a comprehensive analysis of the evolution of working time regulation and its political roots it discusses the studies evaluating the 35 hour working week and examines some of the basic consequences of reversing this policy since 2002 it also highlights unexplored lines of research on this topic

liquidity provision interest rates and unemployment abstract the effective liquidity supply of the economy the weighted sum of all assets that serve as media of exchange matters for interest rates and unemployment we formalize this idea by adding an over the counter market with collateralized trades to the mortensen pissarides model an increase in public liquidity through a higher supply of real government bonds raises the real interest rate crowding out private liquidity and increasing unemployment if unemployment is inefficiently high keeping liquidity scarce can be socially optimal a liquidity crisis affecting the acceptability of private assets as collateral widens the rate of return difference between private and public liquidity also increasing unemployment

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association

a neoclassical perspective on budget deficits i n the 1988 presidential campaign virtually every serious candidate spoke of the urgent need to trim government budget deficits public opinion polls have identified federal deficits as a key economic issue second only to unemployment while many economists are relieved by what they perceive to be a long overdue political response to a critical economic problem others regard the fuss as much ado about nothing it is indeed remarkable that economists can disagree so severely over an issue which commands such a uniform reaction from laymen of widely different ideologies and political affiliations generally speaking there are three schools of thought concerning the economic effects of budget deficits neoclassical keynesian and ricardian before proceeding further it is useful to review the basic structure and implications of each paradigm the neoclassical paradigm envisions farsighted individuals planning consumption over their own life cycles budget deficits raise total lifetime consumption by shifting taxes to subsequent generations if economic resources are fully employed increased consumption necessarily implies decreased saving interest rates must then rise to bring capital markets into balance thus persistent deficits crowd out private capital accumulation in the current economic environment most economists would agree that these consequences would be highly detrimental
