the role of capital and labour in shaping the environmental effects of fiscal stimulus abstract although the macroeconomic consequences of short term fiscal stimulation packages have been thoroughly analysed in the literature still relatively little is known about their environmental effects we discuss an important channel through which short run expansionary fiscal policy influences greenhouse gas emissions we show that fiscal policy exerts its impact not only by increasing general level of economic activity but also by changing the composition of factors of production capital and labour using the dynamic stochastic general equilibrium model of economy we demonstrate that fiscal expansion results in a shift from capital intensive to more labour intensive technologies our panel study proves that the latter tends to be associated with lower emissions of greenhouse gases per unit of production hence our analysis demonstrates that an extensive use of fiscal stimulus during recessions can significantly reduce the environmental burden of the additional units of gdp

democracy volatility and economic development growth stability is an important objective because development requires sustained increases in income because volatility is costly for the poor and because volatility deters growth we study the determinants of average growth and its volatility as a two equation system and find that higher levels of democracy and diversification lower volatility whereas volatility itself reduces growth muslim countries instrument for democracy and measures of diversification identify volatility in contrast to the lack of consensus on the democracy growth relationship the democracy stability link is robust rather than focus on growth this paper forges an alternative link between democracy and development through the volatility channel

democracy and economic growth a meta analysis despite a sizeable theoretical and empirical literature no firm conclusions have been drawn regarding the impact of political democracy on economic growth this article challenges the consensus of an inconclusive relationship through a quantitative assessment of the democracy growth literature it applies meta regression analysis to the population of 483 estimates derived from 84 studies on democracy and growth using traditional meta analysis estimators the bootstrap and fixed and random effects meta regression models it derives several robust conclusions taking all the available published evidence together it concludes that democracy does not have a direct impact on economic growth however democracy has robust significant and positive indirect effects through higher human capital lower inflation lower political instability and higher levels of economic freedom democracies may also be associated with larger governments and less free international trade there also appear to be country and region specific democracy growth effects overall democracy s net effect on the economy does not seem to be detrimental

fair management of social risk we provide a general method for extending social preferences defined for riskless economic environments to the context of risk and uncertainty we apply the method to the problems of managing unemployment allowances in the context of macroeconomic fluctuations and catastrophic risks in the context of climate change the method guarantees ex post fairness and pays attention to individuals risk attitudes while ensuring rationality properties for social preferences revisiting basic ideas from harsanyi s celebrated aggregation theorem harsanyi 1955 the social preferences that we obtain do not always take the form of an expected utility criterion but they always satisfy statewise dominance when we require social preferences to be expected utilities we obtain a variant of harsanyi s result under a weak version of the pareto principle and a maximin criterion under a stronger pareto requirement whenever the ex post social ordering does not depend on people s risk attitudes we also show how non expected utility individual preferences can be accommodated in the approach

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

the optimum quantity of debt abstract we find that the welfare gains to being at the optimum quantity of debt rather than the current us level are small and therefore concerns regarding the high level of debt in the us economy may be misplaced this finding is based on a model of a large number of infinitely lived households whose saving behavior is influenced by precautionary saving motives and borrowing constraints this model incorporates a different role for government debt than is found in standard models and it captures different cost benefit trade offs on the benefit side government debt enhances the liquidity of households by providing an additional means of smoothing consumption and by effectively loosening borrowing constraints on the cost side the implied taxes have adverse wealth distribution and incentive effects in addition government debt crowds out capital via higher interest rates and lowers per capita consumption

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

public debt and redistribution with borrowing constraints we build a model with financial imperfections and heterogeneous agents and analyse the effects of two types of fiscal policy revenue neutral intratemporal redistribution and debt financed tax cuts which we interpret as intertemporal redistribution under flexible prices the two policies are either neutral or display effects that are at odds with the empirical evidence with sticky prices ricardian equivalence always fails a robin hood revenue neutral redistribution to borrowers is expansionary on aggregate activity a uniform debt financed tax cut has a positive present value multiplier on consumption stemming from intertemporal substitution by the savers who hold the public debt

democracy and economic growth a historical perspective recent studies appear to show that democracy has no robust association with economic growth yet all such work assumes that the causal effect of democracy can be measured by a country s regime status in a particular year t which is correlated with its growth performance in a subsequent period t 1 the authors argue that democracy must be understood as a stock rather than a level measure that is a country s growth performance is affected by the number of years it has been democratic in addition to the degree of democracy experienced during that period in this fashion democracy is reconceptualized as a historical rather than a contemporary variable with the assumption that long run historical patterns may help scholars to understand present trends the authors speculate that these secular historical infiuences operate through four causal pathways each of which may be understood as a type of capital physical capital human capital social capital and political capital this argument is tested in a cross country analysis and is shown to be robust in a wide variety of specifications and formats

civil conflict democratization and growth violent democratization as critical juncture in this paper we provide an empirical investigation of the interaction between violent conflicts democratization and growth in the third wave of democratization the effect of democratization is weakened when taking into account the incidence of civil conflict the results show that the growth effect of democratization is heterogeneous and depends on the democratization scenario peaceful transitions to democracy have a significant positive effect on growth that is even larger than reported previously in the literature whereas violent transitions have no or even negative growth effects

new evidence on the relationship between democracy and economic growth it is often maintained that democracy is a luxury which comes at a price in terms of subsequent slower increases in national living standards however various recent cross section studies on economic growth have found evidence that lack of civil and political liberties is negatively correlated with economic growth using a new measure of democracy which is based upon the number of years that a country can be regarded as a democracy the robustness of this relationship is examined both direct and indirect effects of lack of democratic liberties are analysed our main conclusion is that the relationship between democracy and economic growth is not rubust

does democracy cause innovation an empirical test of the popper hypothesis abstract democratic countries produce higher levels of innovation than autocratic ones but does democratization itself lead to innovation growth either in the short or in the long run the existing literature has extensively examined the relationship between democracy and growth but seldom explored the effect of democracy on innovation which might be an important channel through which democracy contributes to economic growth this article aims to fill this gap and contribute to the long standing debate on the relationship between democracy and innovation by offering empirical evidence based on a data set covering 156 countries between 1964 and 2010 the results from the difference in differences method show that democracy itself has no direct positive effect on innovation measured with patent counts patent citations and patent originality

sticky price models of the business cycle can the contract multiplier solve the persistence problem we construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations these fluctuations include persistent movements in output along with the other defining features of business cycles like volatile investment and smooth consumption we assume that prices are exogenously sticky for a short time persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so we find that for a wide range of parameter values the amount of endogenous stickiness is small thus we find that in a standard quantitative model staggered price setting alone does not generate business cycle fluctuations

risk sharing on the labour market and second best wage rigidities the starting point of the analysis is that a significant proportion of the labour force is not covered by efficient labour contracts in particular the non existence of forward labour contracts limits the opportunity of efficient risk sharing through private arrangements among young labour suppliers and capital owners in such a context state dependent labour taxes and employment subsidies would be required to achieve ex ante pareto efficiency in the absence of employment subsidies a certain limited degree of downward wage rigidity is in general pareto superior to full wage flexibility at the second best optimum so defined productive efficiency is sacrificed in some states in order to achieve greater efficiency in risk sharing thus the unemployment associated with wage rigidity is inefficient though voluntary due to the levels of benefits and second best efficient a limited degree of wage discrimination by hiring date is typically part of the second best policy

do financial constraints hold back innovation and growth evidence on the role of public policy abstract this paper provides evidence that capital market imperfections hold back innovation and growth and that public policy can complement capital markets we deliver the evidence by studying the effects of government funding on the behavior of smes in finland by adapting the methodology recently proposed by rajan and zingales rajan r g zingales l 1998 financial dependence and growth american economic review 88 pp 559 587 to firm level data we show that government funding disproportionately helps firms from industries that are dependent on external finance we demonstrate that the result is economically significant and robust to a variety of tests

determinants of patent rights a cross national study abstract this paper presents an index of patent rights for 110 countries for the period 1960 1990 the index is used to examine what factors or characteristics of economies determine how strongly patent rights will be protected the evidence does indicate that more developed economies tend to provide stronger protection but the underlying factors which influence patent protection levels are the country s level of research and development r d activity market environment and international integration which are correlated with its level of development the results qualify however that r d activity influences patent protection levels after a nation s research sector reaches a critical size an implication of this is that to raise patent protection levels in weakly protecting countries it is important to foster a significant research base in those countries and thereby create incentives for protecting patent rights

social capital innovation and growth evidence from europe this paper investigates the interplay between social capital innovation and economic growth in the european union we identify innovation as an important mechanism that transforms social capital into economic growth in an empirical investigation of 102 european regions in the period 1990 2002 we show that higher innovation performance is conducive to economic growth and that social capital affects growth indirectly by fostering innovation our estimates suggest that there is only a limited role for a direct effect of social capital on economic growth

fiscal multipliers under an interest rate peg of deterministic versus stochastic duration this paper revisits the size of the fiscal multiplier the experiment is a fiscal expansion under the assumption of a pegged nominal rate of interest we demonstrate that a quantitatively important issue is the articulation of the exit from the policy experiment if the monetary fiscal expansion is stochastic with a mean duration of t periods the fiscal multiplier can be unboundedly large however if the monetary fiscal expansion is for a fixed t periods the multiplier is much smaller our explanation rests on a jensen s inequality type argument the deterministic multiplier is convex in duration and the stochastic multiplier is a weighted average of the deterministic multipliers the quantitative difference in the two multipliers also arises in a model with capital and in the baseline nonlinear model however the differences between the two is less pronounced in the nonlinear models

do national patent laws stimulate domestic innovation in a global patenting environment a cross country analysis of pharmaceutical patent protection 1978 2002 this paper evaluates the effects of patent protection on phar maceutical innovations for 26 countries that established pharmaceutical patent laws during 1978 2002 controlling for country characteristics through matched sampling techniques to establish two proper comparison sets among 92 sampled countries and through country pair fixed effects regressions this study yields robust results national patent protection alone does not stimulate domestic innovation as estimated by changes in citation weighted u s patent awards domestic r d and pharmaceutical industry exports however domestic innovation accelerates in countries with higher levels of economic development educational attainment and economic freedom additionally there appears to be an optimal level of intellectual property rights regulation above which further enhancement reduces innovative activities

liquidity assets and business cycles abstract the objective here is to evaluate the quantitative importance of financial frictions in business cycles the analysis shows that a negative financial shock can cause aggregate investment employment and consumption to fall with output despite this realistic comovement among macro quantities a negative financial shock generates an equity price boom as the shock tightens firms financing constraint this counterfactual response of the equity price is robust to a wide range of variations in how financial frictions are modeled and whether financial shocks affect asset liquidity or firms collateral constraints some possible resolutions to this puzzle are discussed

fiscal policy in an expectations driven liquidity trap we study the effects of fiscal policy interventions in a liquidity trap in a model with nominal rigidities and an interest rate rule in a liquidity trap caused by a self fulfilling state of low confidence higher government spending has deflationary effects that reduce the spending multiplier when the zero lower bound is binding instead cuts in marginal labor tax rates are inflationary and become more expansionary when the zero lower bound is binding these findings contradict popular views about the effects of fiscal policy in a liquidity trap

democratisation and growth this article challenges cross sectional findings that democracy has a negligible effect on growth we employ a new dataset of political transitions during the third wave of democratisation and examine the within effect of democratisation in countries that abandoned autocracy and consolidated representative institutions the panel estimates imply that on average democratisations are associated with a 1 increase in annual per capita growth the dynamic analysis reveals that while during the transition growth is slow in the medium and long run it stabilises at a higher level this evidence favours development theories of democratic rule and friedrich hayek 1960 s idea that the merits of democracy appear in the long run leading politicians and commentators have argued that democratisation will bring prosperity and growth into pariah and economically poorly performing countries 1 others however remain sceptical pointing to the mixed and inconclusive empirical evidence the old debate dating back to plato and aristotle on which political regime is socially and economically optimal arises again this debate is not purely academic and philosophical as it has important policy implications in the last thirty years the world has experienced an unprecedented move towards democratic institutions influential policy makers and scholars urge western authorities to foster democratic movements in totalitarian countries see the economist article philosophers and kings june 19th 2003 yet the question remains will democratisation bring economic growth to assess the average growth effect of a successful democratic transition we analyse the evolution of annual real per capita gdp growth before and after incidents of permanent democratic reform in the 1960 2003 period in our analysis we exploit a newly constructed dataset of permanent democratisations during the so called third wave of democratisation and the 1990s when many former socialist countries moved towards representative rule the panel results reveal new evidence that contrast with the previous mainly cross sectional work first conditioning on time invariant country characteristics and global shocks a permanent democratisation is associated with approximately a one half to one per cent increment in annual real per capita gdp growth second a dynamic j shaped effect emerges with considerable though not this article is a major revision of an earlier paper titled aristotle was right stable democracy fosters

can government purchases stimulate the economy this essay briefly reviews the state of knowledge about the government spending multiplier drawing on theoretical work aggregate empirical estimates from the united states as well as cross locality estimates i assess the likely range of multiplier values for the experiment most relevant to the stimulus package debate a temporary deficit financed increase in government purchases i conclude that the multiplier for this type of spending is probably between 0 8 and 1 5 jel e23 e62 h50

unequal uncertainties and uncertain inequalities an axiomatic approach abstract in this paper we provide an axiomatic characterization of social welfare functions for uncertain incomes our most general result is that a small number of reasonable assumptions regarding welfare orderings under uncertainty rule out pure ex ante as well as pure ex post evaluations any social welfare function that satisfies these axioms should lie strictly between the ex ante and the ex post evaluations of income distributions we also provide an axiomatic characterization of the weighted average of the minimum and the maximum of ex post and ex ante evaluations

let s agree that all dictatorships are equally bad this paper shows that a minimal degree of consideration for other people s well being enables society to agree that one social policy is the best i offer axioms that imply that this best policy maximizes a weighted sum of individual utilities the weight of each individual is the inverse of his or her maximal possible utility from social endowments the suggested policy is not sensitive to the choice of the von neumann morgenstern utilities the key axiom is that individuals agree that giving all the endowments always to one person is as bad as giving them to any other person

the political economy of development a cross national causality test of development democracy growth hypothesis the empirical investigation of the development democracy growth hypothesis estimates positive correlations and causal associations between development and democracy and democracy and growth among the preconditions for the emergence of democracy market and culture show strong and highly significant positive effects which are largely transmitted directly development affects democracy directly and indirectly via education and investment the positive causal association between democracy and growth is transmitted both directly and indirectly via labor and welfare accordingly the hypothesized compatibility between economic development and political democracy is confirmed while rejecting the trade off between political democracy and economic growth

the national system of innovation in historical perspective contrary to some recent work on so called globalisation this paper argues that national and regional systems of innovation remain an essential domain of economic analysis their importance derives from the networks of relationships which are necessary for any firm to innovate whilst external international connections are certainly of growing importance the influence of the national education system industrial relations technical and scientific institutions government policies cul tural traditions and many other national institutions is fundamental the historical examples of germany japan and the former ussr illustrate this point as well as the more recent contrast between east asian and latin american countries introduction the national system of friedrich list according to this author s recollections the first person to use the expression national system of innovation was bengt ake lundvall and he is also the editor of a highly original and thought provoking book 1992 on this subject however as he and his colleagues would be the first to agree and as lundvall himself points out the idea actually goes back at least to friedrich list s conception of the national system of political economy 1841 which might just as well have been called the national system of innovation the main concern of list was with the problem of germany overtaking england and for underdeveloped countries as germany then was in relation to england he advocated not only protection of infant industries but a broad range of policies designed to accelerate or to make possible industrialisation and economic growth most of these policies were concerned with learning about new technology and applying it the racialist and colonialist overtones of the book were in strong contrast to the inter nationalist cosmopolitan approach of the classical free trade economists and list s belief that holland and denmark should join the german bund and acquire german nationality because of their descent and whole character reads somewhat strangely in the european community of today nevertheless despite these unattractive features of his outlook he clearly anticipated many contemporary theories after reviewing the changing ideas of economists about development in the years since the second world war the world bank 1991 concludes that it is intangible investment in knowledge accumulation which is decisive rather than physical capital investment as was at one time believed pages 33 35 the report cites the new growth theory

is there a fiscal free lunch in a liquidity trap this paper uses a dsge model to examine the eects of an expansion in government spending in a liquidity trap the spending multiplier can be much larger than in the normal situation if the liquidity trap is very persistent and scal stimulus can be rapidly implemented moreover the budgetary costs may be minimal as the large response of output boosts tax revenues allowing for something close to a scal free lunch however we caution that the multiplier may be much smaller under plausible implementation lags for many types of public spending and or if the liquidity trap lasts less than two years in addition because the marginal impact of scal expansion decreases in the scale of the outlay it is crucial to distinguish between average and marginal multipliers

fiscal shocks and their consequences this paper investigates the response of hours worked and real wages to fiscal policy shocks in the post world war ii us we identify these shocks with exogenous changes in military purchases and argue that they lead to a persistent increase in government purchases and tax rates on capital and labor income and a persistent rise in aggregate hours worked as well as declines in real wages the shocks are also associated with short lived rises in aggregate investment and small movements in private consumption we describe and implement a methodology for assessing whether standard neoclassical models can account for the consequences of a fiscal policy shock simple versions of the neoclassical model can account for the qualitative effects of a fiscal shock once we allow for habit formation and investment adjustment costs the model can also account reasonably well for the quantitative effects of a fiscal shock

income and democracy existing studies establish a strong cross country correlation between income and democracy but do not control for factors that simultaneously affect both variables we show that controlling for such factors by including country fixed effects removes the statistical association between income per capita and vari ous measures of democracy we present instrumental variables estimates that also show no causal effect of income on democracy the cross country corre lation between income and democracy reflects a positive correlation between changes in income and democracy over the past 500 years this pattern is con sistent with the idea that societies embarked on divergent political economic development paths at certain critical junctures jel d7 e 1

new keynesian versus old keynesian government spending multipliers renewed interest in fiscal policy has increased the use of quantitative models to evaluate policy because of modelling uncertainty it is essential that policy evaluations be robust to alternative assumptions we find that models currently being used in practice to evaluate fiscal policy stimulus proposals are not robust government spending multipliers in an alternative empirically estimated and widely cited new keynesian model are much smaller than in these old keynesian models the estimated stimulus is extremely small with gdp and employment effects only one sixth as large and with private sector employment impacts likely to be even smaller we investigate the sensitivity of our findings with regard to the response of monetary policy the zero bound on nominal interest rates and the inclusion of an empirically relevant degree of rule of thumb behaviour in the new keynesian model in addition we relate our findings using estimated structural macroeconomic models to the recent literature using reduced form regression techniques
