union coverage and profitability among u s firms this paper utilizes unique survey data on labor union coverage at the firm level to examine union effects on the profitability of 705 u s companies during the 1970s market value and earnings are estimated to be about 10 15 percent lower in an average unionized company than in a nonunion company following extensive control for firm and industry characteristics deleterious union effects on firm profitability are sizable throughout the 1972 80 period but vary considerably across industries the relatively poor profit performance of unionized companies may help explain the recent decline in u s union membership the author thanks the w e upjohn institute for employment research for financial support elizabeth gregory for assistance with the union coverage survey zvi griliches for providing access to the rd donald deere terry seaks and anonymous referees for helpful suggestions and seminar participants at connecticut florida state harvard texas a m and william and mary for comments on earlier versions of this research

the impact of fiscal policy on profits i introduction a large number of policy making decisions rely on the key issue of the impact of fiscal policy on the economy therefore it is not surprising that the effect of fiscal policy on macroeconomic aggregates has been extensively studied in the empirical literature 1 several authors starting with blanchard and perotti 2002 have attempted to estimate the effect of government spending shocks on output and other variables in the context of structural var models see perotti 2008 for a survey this interest has been renewed since the 2008 2009 recession given the unprecedented size of fiscal packages worldwide barro and redlick 2009 hall 2009 an important part of this literature focuses on the theoretical and empirical investigation of the fiscal policy transmission channels theories of fiscal policy transmission differ in their implications regarding the response of different macroeconomic variables to government spending shocks for example the neoclassical model predicts a negative impact of government spending on real wages and consumption while this prediction is challenged by new keynesian models to that end an important branch of empirical literature on fiscal multipliers has investigated the transmission channels of fiscal policy by looking mainly at the response of private consumption and real wages 2 this paper deals with an important but relatively under investigated channel of fiscal policy transmission which is the effect of fiscal policy on profits as pointed out by hall 2009 the impact of fiscal shocks on the markup of price over marginal cost is important for understanding the functioning of the fiscal multiplier in the purely neoclassical general equilibrium model a rise in government spending produces a negative wealth effect the labor supply curve shifts outward and real wages and consumption fall this implies that the output multiplier will be well below unity a keynesian type fiscal multiplier implying a large positive output effect and positive responses of private consumption and real wages to increased government spending relies on a negative response of the markup of price over marginal cost to an increase in economic activity the intuition is that a decrease in the price marginal cost markup in response to higher government spending allows a rise in wages or at least a smaller reduction in wages compared with the case when the markup is constant a rise in wages would then imply that households will substitute away from leisure and into consumption therefore if the markup is countercyclical conditional on government spending shocks sizeable output multipliers of fiscal spending are consistent with existing empirical evidence that fiscal shocks are not related to strong decreases in real wages or consumption blanchard and perotti 2002 fatas and mihov 2001 gall david lopez salid and valles 2007 perotti 2005 2008 in general a new keynesian model with sticky prices implies a countercyclical markup ratio as input prices rise in a boom while output prices stay constant however for understanding the fiscal policy transmission the key factor is markup and not price stickiness itself as a countercyclical markup could also be implied by models with flexible prices when the desired markup changes in response to a shock 3 a model which assigns a central role to markups for fiscal policy transmission has been presented by ravn schmitt grohe and uribe 2007 assuming that demand has a price inelastic component that is a function of deep habits a government spending shock that leads to a positive output response increases the share of the price elastic component of demand causing a rise in the overall demand elasticity and a corresponding decline in the optimal markup 4 thus for a sufficient decline in the markup the resulting rise in wages induces households to substitute away from leisure and into consumption thereby more than offsetting the negative wealth effect of government spending predicted by the neoclassical model

on identification of bayesian dsge models this article is concerned with local identification of individual parameters of dynamic stochastic general equilibrium dsge models estimated by bayesian methods identification is often judged by a comparison of the posterior distribution of a parameter with its prior however these can differ even when the parameter is not identified instead we propose two bayesian indicators of identification the first follows a suggestion by poirier of comparing the posterior density of the parameter of interest with the posterior expectation of its prior conditional on the remaining parameters the second examines the rate at which the posterior precision of the parameter gets updated with the sample size using data simulated at the parameter point of interest for an increasing sequence of sample sizes t for identified parameters the posterior precision increases at rate t for parameters that are either unidentified or are weakly identified the posterior precision may get updated but its rate of update wi

pricing in a customer market in standard pricing models movements in demand are partially offset by price responses in a customer market however price markups may decrease with high demand thus price may magnify rather than stabilize demand movements i consider a monopolist selling a good of which first time consumers are uncertain repeat customers know that the product works the monopolist trades the objectives of exploiting past customers and attracting new ones in a period with many new potential customers the monopolist gives more weight to attracting and lowers its markup last i examine some evidence on whether expansions are periods with disproportionately many new customers

does my contribution to your crowdfunding project matter abstract in this study we consider the dynamics of crowdfunding project support over time we propose that people support crowdfunding projects financially when they believe that their contribution will make an impact because perceptions of impact are positively related to goal proximity we predict that support for a crowdfunding project will increase as the project funding approaches its target goal in addition because motivation decreases after a goal is attained we further predict that crowdfunding contributions will significantly decrease after the target goal is reached we find strong support for these hypotheses from a large scale field study involving kickstarter furthermore we show that several factors related to the expected impact moderate the effects of goal proximity that is the positive effect of goal proximity on project support is accentuated if the project is nearing its funding deadline if the target goal is relatively small or if the project has limited early support

the economics of small business finance the roles of private equity and debt markets in the financial growth cycle abstract this article examines the economics of financing small business in private equity and debt markets firms are viewed through a financial growth cycle paradigm in which different capital structures are optimal at different points in the cycle we show the sources of small business finance and how capital structure varies with firm size and age the interconnectedness of small firm finance is discussed along with the impact of the macroeconomic environment we also analyze a number of research and policy issues review the literature and suggest topics for future research

tax structure and growth are some taxes better than others using pooled cross sectional data from 23 oecd countries between1965 and 1990 i find evidence that the tax structure affectseconomic growth specifically the proportion of tax revenueraised by taxing personal income has a negative correlation witheconomic growth this result is robust to a rigorous sensitivityanalysis where i control for other plausible growth determinantsin a systematic manner also there is some empirical evidencethat tax progressivity measured in terms of the long run incomeelasticity of tax revenue is associated with low economicgrowth

growth income inequality and fiscal policy what are the relevant trade offs we develop an endogenous growth model with elastic labor supply in which agents differ in their initial endowments of physical capital in this context the growth rate and the distribution of income are jointly determined we then examine the distributional impact of different ways of financing an investment subsidy policies aimed at increasing the growth rate result in a more unequal distribution of pre tax income consistent with the positive correlation between income inequality and growth observed in the recent empirical literature however there is no conflict between efficiency and equity if inequality is measured in terms of the distribution of welfare

a little bit more evidence on the natural rate hypothesis from the u k abstract the evidence for the neutrality of anticipated changes in monetary policy in the u k over the period 1963q1 1982q1 is examined breaks in the stochastic process generating the money stock are used to identify the model the results are generally unfavourable to the proposition that only unanticipated money matters

cyclical effects of government s employment and goods purchases distinguishing between the goods purchase and employee compensation components of government spending is important shocks to government goods purchases and shocks to government employment have the opposite effects on private output private employment and private investment moreover with this distinction in place quantitative analysis reveals that government spending is no longer a significant driving source of the u s business cycle on the contrary the components of government spending are procyclical in the u s data primarily because of their positive responses to the output fluctuations generated by technology shocks copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

political business cycles 40 years after nordhaus the aim of this article is to survey the huge literature that has emerged in the last four decades following nordhaus s rev econ stud 42 2 169 190 1975 publication on political business cycles pbcs i first propose some developments in history of thought to examine the context in which this ground breaking contribution saw the light of the day i also present a simplified version of nordhaus s model to highlight his key results i detail some early critiques of this model and the fields of investigations to which they gave birth i then focus on the institutional context and examine its influence on pbcs the actual research agenda finally i derive some paths for future research

determinacy and identification with taylor rules the new keynesian taylor rule theory of inflation determination relies on explosive dynamics by raising interest rates in response to inflation the fed induces ever larger inflation unless inflation jumps to one particular value on each date however economics does not rule out explosive inflation so inflation remains indeterminate attempts to fix this problem assume that the government will choose to blow up the economy if alternative equilibria emerge by following policies we usually consider impossible the taylor rule is not identified without unrealistic assumptions thus taylor rule regressions do not show that the fed moved from passive to active policy in 1980

crowdfunding and innovation entrepreneurs have started relying on crowdfunding to fund their investments this paper surveys the literature linking crowdfunding with innovation in entrepreneurial firms two distinct areas are discussed first crowdfunding has the potential to foster innovation by offering new sources of capital to innovation driven firms and thereby reduce the funding gap for innovative startups second crowdfunding offers a way for the crowd to participate in the innovation process by providing feedback to the entrepreneur this feedback can take various forms including providing ideas on the development of the product during and after the campaign in the spirit of crowdsourcing and providing valuable information on the future demand for the new product

does anticipated aggregate demand policy matter further econometric results a heated debate has arisen over what modigliani has dubbed the macro rational expections mre hypothesis this hypothesis embodies two component hypotheses 1 rational expectations and 2 short run neutrality i e that anticipated changes in aggregate demand will have already been taken into account in economic agents behavior and will thus evoke no output or employment response together these component hypotheses imply that deterministic feedback policy rules will have no effect on business cycle fluctuations the irrelevance of these types of policy rules is inconsistent with much previous macro theorizing as well as with the views of policymakers it is thus an extremely controversial proposition which requires a wide range of empirical research this paper is a sequel to a previous paper by the author that paper developed a methodology for testing the mre hypothesis and found that anticipated money growth does matter to the business cycle this paper extends the analyses to cases where the rate of nominal gnp growth or the inflation rate rather than money growth is the aggregate demand variable the empirical results are also negative on the mre hypothesis and its corresponding policy ineffectiveness proposition this abstract was borrowed from another version of this item

the effect of fiscal performance on local government election results in israel 1989 1998 abstract we discuss the circumstances under which voters in local elections will reward fiscal responsibility and suggest that such circumstances evolved in israel in the mid 1990s we present empirical evidence that indeed fiscal performance of mayors substantially affected their reelection probability in the 1998 campaign but not in the 1989 and 1993 campaigns changes in the political environment enforcement of audit and financial reporting requirements tougher imposition of hard budget constraints and the development of local media are proposed as explanations the hypotheses that the fiscal variables reflect the income level at the locality or the mayor s success in extracting resources from the central government are tested and rejected

forming priors for dsge models and how it affects the assessment of nominal rigidities abstract we discuss prior elicitation for the parameters of dynamic stochastic general equilibrium dsge models and provide a method for constructing prior distributions for a subset of these parameters from beliefs about steady state relationships and second moments of the endogenous variables the empirical application documents how the specification of the prior distribution affects our assessment of the relative importance of price and wage rigidities in a new keynesian dsge model

testing for indeterminacy an application to u s monetary policy reply this paper considers a prototypical new keynesian model in which the equilibrium is undetermined if monetary policy is passive the likelihood based estimation of dynamic equilibrium models is extended to allow for indeterminacies and sunspot fluctuations we construct posterior weights for the determinacy and indeterminacy region of the parameter space and estimates for the propagation of fundamental and sunspot shocks according to the estimated model u s monetary policy post 1982 is consistent with determinacy whereas the pre volcker policy is not we find that before 1979 indeterminacy substantially altered the propagation of shocks

outside enterpreneurial capital this article investigates factors that affect rejection rates in applications for outside finance among different types of investors banks venture capital funds leasing firms factoring firms trade customers and suppliers partners and working shareholders private individuals and other sources taking into account the non randomness in a firm s decision to seek outside finance the data support the traditional pecking order theory further the data indicate that firms seeking capital are typically able to secure their requisite financing from at least one of the different available sources however external finance is often not available in the form that a firm would like this article engages with four interrelated empirical questions first what are the characteristics of privately held entrepreneurial firms that seek external outside finance and what drives the request for capital from the different potential sources of external finance banks venture capitalists private individuals leasing factoring suppliers customers partners working shareholders among other sources second what are the factors that lead to rejection or acceptance of requests for external finance given this non randomness in the types of firms that seek external finance in the spirit of heckman 1976 1979 third as various forms of financing are far from being perfect substitutes are there differences in the ability of firms to obtain capital from the different available sources fourth can firms obtain all of their desired capital from the different available sources even if it is not in the form they would like it is widely recognised that the decision to seek external finance and the type of financing sought is related to information asymmetries faced by investors regarding the entrepreneurial firm s quality see for example jensen and meckling 1976 1 where

opportunistic politicians and fiscal outcomes the curious case of vorarlberg using a unique set of electoral rules present in the austrian state of vorarlberg we explore the question ofwhether direct election of the mayor affects the size of local governments using difference in differences estimation and propensity score matching we find evidence that direct elections of the mayor are associated with less expenditure on public administration and public personnel and higher expenditure in the visible categories of spending i e transportation infrastructure and economic subsidies to firms and individuals

a critique of the proposed tests of the natural rate rational expectations hypothesis the failure of the governments of most industrialised countries over the past decade to deal successfully with the problems of rising unemployment and high and often accelerating rates of price and wage inflation has revived interest in the pre keynesian macro economics of sound money and has renewed the controversy of the 1930 s over what governments should or should not do if they wish to achieve full employment with reasonable price stability in democratic societies keynesian economics has come under attack both by those who primarily oppose interventionist policies on ideological grounds and by the so called new classical macro economists who adhere to the natural rate of unemployment hypothesis nrh advanced by phelps i967 and friedman i 968 and the hypothesis of rational formation of expectations reh originally due to muth i96i armed with this joint natural rate rational expectations nr re hypothesis the new classical macro economists have argued that in a world capable of being represented by linear or log linear relations with a unique and stable equilibrium and no information discrepancy between the government and the private sector no government macro economic policy whether monetary or fiscal no matter how ingeniously formulated and how effectively implemented can have any systematic or lasting impact upon the level of output or the rate of unemployment 2 clearly this fundamental policy

on the ineffectiveness of tax policy in altering long run growth harberger s superneutrality conjecture abstract in 1964 harberger conjectured that although theory predicts that changes in tax rates affect investment and growth in the long run in practice tax policy is an ineffective instrument to influence growth this paper provides theoretical and empirical evidence in favor of this view the growth effects of tax policy in the class of endogenous growth models driven by human capital accumulation are examined and numerical simulations of these models confirm the results harberger predicted cross country panel regressions estimated using a new method for measuring effective tax rates produce significant investment effects from taxes that are consistent with negligible growth effects these results are robust to the introduction of other growth determinants

testing the endogenous growth model public expenditure taxation and growth over the long run endogenous growth models such as barro 1990 predict that government expenditure and taxation will have both temporary and permanent effects on growth we test this prediction using panels of annual and period averaged data for oecd countries during 1970 95 isolating long run from short run fiscal effects our results strongly support the endogenous growth model and suggest that long run fiscal effects are not fully captured by period averaging and static panel methods unlike previous investigations our estimates are free from biases associated with incomplete specification of the government budget constraint and do not appear to result from endogeneity of fiscal or investment variables jel classification h30 o40 validation du modele de croissance endogene depenses publiques fiscalite et croissance a long terme des modeles de croissance endogene comme celui de barro 1990 predisent que depenses gouvernementales et fiscalite vont avoir des effets temporaires et permanents sur la croissance on met cette prevision au test a l aide de donnees annuelles et pour certaines moyennes couvrant des sous periodes pour les pays de l ocde 1970 95 dans le but de departager les effets a court et a long terme les resultats valident fortement le modele de croissance endogene et suggerent que les effets fiscaux a long terme ne sont pas pleinement captures par des methodes utilisant des moyennes ou des methodes statiques contrairement aux resultats d enquetes anterieures les resultats proposes ne souffrent pas de distorsions attribuables a une specification incomplete de la contrainte budgetaire du gouvernement et ne semblent pas etre l effet d echo de l endogeneite des variables fiscales et de l investissement

contemporary topics in finance a collection of literature surveys finance plays a critical function in economies and continues to evolve in practice complemented by research policy and regulation the articles in this special issue provide up to date reviews of contemporary topics in finance unconventional monetary policy implicit bank guarantees and financial fraud are in various ways associated with rethinks stimulated by the global financial crisis the topics of inflation risk premia finance and productivity angel investing venture capital relationship lending and microfinance have benefitted from increased research associated with more data and use in practice the final two topics of crowdfunding and crypto currencies are the products of recent technological developments

what s in a picture evidence of discrimination from prosper com abstract we find evidence of significant racial disparities in a new type of credit market known as peer to peer lending loan listings with blacks in the attached picture are 25 to 35 percent less likely to receive funding than those of whites with similar credit profiles despite the higher average interest rates charged to blacks lenders making such loans earn a lower net return compared to loans made to whites with similar credit profiles because blacks have higher relative default rates these results provide insight into whether the discrimination we find is taste based or statistical

is the growth of small firms constrained by internal finance this paper examines the long standing theory that the growth of small firms is often constrained by the quantity of internal finance under plausible assumptions when financing constraints are binding an additional dollar of internal finance should generate slightly more than an additional dollar of growth in assets this quantitative prediction should not hold for the relatively small number of firms which access external equity we test these predictions with a panel of more than 1 600 small firms and find that the growth of most firms is constrained by internal finance our results have implications for several different research literatures including models of firm growth

running for office again evidence from portuguese municipal elections using a data set that covers all portuguese mainland municipalities for the period 1979 2005 this study performs an empirical analysis of the economic determinants of mayors decisions to run for another term in office the literature on the subject is mainly centered on the united states and as far as we know there are no papers addressing the economic factors influencing those choices

how optimal is us monetary policy using a small scale microfounded dsge model with markov switching in shock variances and policy parameters we show that the data preferred description of us monetary policy is a time consistent targeting rule with a marked increase in conservatism after the 1970s however the fed lost its conservatism temporarily in the aftermath of the 1987 stock market crash and again following the 2000 dot com crash and has not subsequently regained it the high inflation of the 1970s would have been avoided had the fed been able to commit even without the appointment of paul volcker or the reduction in shock volatilities

evaluating the information matrix in linearized dsge models abstract in this note we show how the stochastic general equilibrium dsge models can be evaluated analytically the result is useful for the estimation and identification analysis of such models

monopolistic competition as a foundation for keynesian macroeconomic models a general equilibrium macroeconomic model based on monopolistic competition is presented the model exhibits a traditional multiplier in the short run but due to free entry the multiplier disappears in the long run by construction all agents are fully rational the keynesian results are a consequence of the assumption of monopolistic competition which creates a divergence between optimal private behavior and optimal social behavior

the effect of entrepreneurial rhetoric on microlending investment an examination of the warm glow effect microlending provides a valuable alternative to traditional financing for entrepreneurs in impoverished countries drawing from theory on political rhetoric and the concept of warm glow giving we examine characteristics of entrepreneurial narratives that are related to how quickly entrepreneurs receive funding using a sample of 6051 narratives from entrepreneurs in developing countries we demonstrate that narratives higher in language indicating blame and present concern lead to more rapid funding while narratives higher in accomplishment tenacity and variety lead to slower funding our findings suggest that the presentation of investment profiles should be carefully managed to maximize funding likelihood

weak instrument robust tests in gmm and the new keynesian phillips curve we discuss weak instrument robust statistics in gmm for testing hypotheses on the full parameter vector or on subsets of the parameters we use these test procedures to reexamine the evidence on the new keynesian phillips curve model we find that u s postwar data are consistent with the view that inflation dynamics are predominantly forward looking but we cannot rule out the presence of considerable backward looking dynamics moreover the phillips curve has become flatter recently and this is an important factor contributing to its weak identification

introduction funding gaps theoretical and empirical foundations of government policies to plug alleged business funding gaps are highly controversial but rarely subject to wide ranging in depth debate this symposium from major scholars in the field provides a counterbalance topics addressed cover the theory of lending under asymmetric information its implications for overlending relationship lending as a market solution to information asymmetries government emulation of private sector decision making to eliminate underprovision of high tech equity and theoretically based empirical work testing for funding deficiencies in the high tech sector despite the very different and potentially contradictory contributions the result is surprisingly a set of mutually agreed policy conclusions

price level determinacy with an interest rate policy rule and rational expectations abstract this paper reconsiders a result obtained by sargent and wallace namely that price level indeterminacy obtains in their model if the monetary authorities adopt a feedback rule for the interest rate rather than the money stock it is shown that the indeterminacy vanishes if the interest rate rule is chosen so as to have a desired effect on the expected quantity of money demanded this holds even if considerable weight is given in the choice of a rule to the aim of smoothing interest rate fluctuations

the identification of rational expectations models under structural neutrality abstract this note shows that in the structural neutrality version of the linear rational expectations model the parameters measuring the strength of response to unanticipated shocks cannot be identified in the absence of restrictions on the covariance properties of the structural disturbances the consequences of this result for the commonly used two step estimation method are explored

fiscal policy and reelection in brazilian municipalities this paper uses a new panel of more than 2 000 brazilian municipalities over 13 years to analyze the influence of public expenditures on the probability of mayors reelec tion we examine brazilian municipal elections from 1988 to 2000 using a logit fixed effects model the results suggest that mayors who spend more during their terms of office increase the probability of their own reelection or of a successor of the same political party in par ticular higher capital spending over the years preceding elections and current expenditures in election years are beneficial to brazilian incumbent mayors

fiscal deficits and growth in developing countries this paper examines the relation between fiscal deficits and growth for a panel of 45 developing countries based on a consistent treatment of the government budget constraint it finds evidence of a threshold effect at a level of the deficit around 1 5 of gdp while there appears to be a growth payoff to reducing deficits to this level this effect disappears or reverses itself for further fiscal contraction the magnitude of this payoff but not its general character necessarily depends on how changes in the deficit are financed through changes in borrowing or seigniorage and on how the change in the deficit is accommodated elsewhere in the budget we also find evidence of interaction effects between deficits and debt stocks with high debt stocks exacerbating the adverse consequences of high deficits

a quarterly model of unanticipated monetary growth output and the price level in the u k 1963 1978 abstract this paper develops and estimates using quarterly data from 1963 to 1978 a three equation model of the u k economy in which output is affected only by unanticipated monetary growth whereas the price level is influenced by both anticipated and unanticipated changes in the money supply expectations of monetary growth are assumed to be muth rational the model was estimated using efficient procedures and tests of the over identifying restrictions were favourable to the model specification in particular anticipated monetary growth was found to have no significant effect on output

the persistence of shocks to profitability in this study we use data for 1981 through 1994 on a large sample of u s companies to examine the persistence of incremental industry corporate parent and business specific effects on profitability our results indicate that the incremental effects of industry on profitability persist longer than the incremental effects of the corporate parent and of the specific business changes in industry structure have a more persistent impact on profitability than do changes in firm structure

measuring prior sensitivity and prior informativeness in large bayesian models abstract in large bayesian models such as modern dsge models it is difficult to assess how much the prior affects the results this paper derives measures of prior sensitivity and prior informativeness that account for the high dimensional interaction between prior and likelihood information the basis for both measures is the derivative matrix of the posterior mean with respect to the prior mean which is easily obtained from markov chain monte carlo output we illustrate the approach by examining posterior results in the small model of lubik and schorfheide 2004 and the large model of smets and wouters 2007

bayesian estimation of dsge models identification using a diagnostic indicator koop pesaran and smith 2013 suggest a simple diagnostic indicator for the bayesian estimation of the parameters of a dsge model they show that if a parameter is well identioed the precision of the posterior should improve as the artiocial data size t increases and the indicator checks the speed at which precision improves as it does not require any additional programming a researcher just needs to generate artiocial data and estimate the model with increasing sample size t we apply this indicator to the benchmark smets and woutersi 2007 dsge model of the us economy and suggest how to implement this indicator on dsge models

fragmented fiscal policy abstract this paper explores on a panel of 19 oecd countries the role of fragmentation in determining fiscal outcomes over the 1970 95 period we first define the notion of fragmentation of fiscal policy making as the degree to which the costs of a dollar of aggregate expenditure are internalized by individual decision makers empirically this notion has two key logical components the number of decision makers and the rules of the game or the budget process in turn the number of decision makers can refer to the number of parties in a coalition or the number of ministers in the cabinet we test all these determinants against each other and against perhaps the oldest explanation of all ideology we show that cabinet size and to a lesser degree coalition size and ideology are significant and robust determinants of fiscal outcomes in particular transfers are the budget items most affected by these factors

fiscal policy multipliers the role of monopolistic competition scale economies and intertemporal substitution in labour supply a dynamic macroeconomic model of monopolistic competition is developed for the closed economy forward looking consumers demand differentiated goods supply labour and save part of their income in the form of shares producers manufacture the differentiated goods by using labour and capital we study the short run transition and long run effects of fiscal policy comparisons with the new classical case of perfect competition are made simple expressions far multipliers are derived the sensitivity of the multipliers for diversity preference and ethier productivity effects intratemporal and intertemporal substitution effects and markup effects under free and restricted entry are also studied

an integrated view of tests of rationality market efficiency and the short run neutrality of monetary policy abstract this paper analyzes an important class of models in which expectations play an important role topics included in the analysis are tests of 1 rationality of forecasts in either market or survey data 2 capital market efficiency 3 the short run neutrality of monetary policy and 4 granger causality in macroeconometric models the common elements of these tests are highlighted in particular cross equation tests for rationality or the short run neutrality of money are shown to be equivalent to more common regression tests in the literature these results demonstrate that the exact specification of the relevant information set used in rational forecasts is not necessary for the cross equation tests to have desirable asymptotic properties also discussed are the conditions for identification of coefficients and testability of hypotheses

transparency political polarization and political budget cycles in oecd countries we investigate the effects of fiscal transparency and political polarization on the prevalence of electoral cycles in fiscal balance while some recent political economy literature on electoral cycles identifies such cycles mainly in weak and recent democracies in contrast we show conditioning on a new index of institutional fiscal transparency that electoral cycles in fiscal balance are a feature of many advanced industrialized economies using a sample of 19 oecd countries in the 1990s we identify a persistent pattern of electoral cycles in low er transparency countries while no such cycles can be observed in high er transparency countries furthermore we find in accordance with recent theory that electoral cycles are larger in politically more polarized countries

identifying the new keynesian phillips curve phillips curves are central to discussions of inflation dynamics and monetary policy the hybrid new keynesian phillips curve nkpc describes how past inflation expected future inflation and a measure of real aggregate demand drive the current inflation rate this paper studies the potential weak identification of the nkpc under generalized method of moments and traces this syndrome to a lack of higher order dynamics in exogenous variables we employ analytic methods to understand the economics of the nkpc identification problem in the canonical three equation new keynesian model we revisit the empirical evidence for the usa the uk and canada by constructing tests and confidence intervals based on the anderson and rubin 1949 statistic which is robust to weak identification we also apply the guggenberger and smith 2008 lm test to the underlying nkpc pricing parameters both tests yield little evidence of forward looking inflation dynamics copyright 2008 john wiley sons ltd

imperfect competition and the fiscal multiplier the impact of fiscal policy in an economy with a monopolistic output market but a perfectly competitive labor market is examined both in the short run with a fixed number of firms and in the long run with free entry the main innovation of the paper is the generality of the assumptions about preferences and technology which enable the authors to examine the robustness of the relationship between the degree of monopoly and the fiscal multiplier found by r startz 1989 n g mankiw 1988 and h d dixon 1987 the specific results of these papers are found to rest on two assumptions constant returns and cobb douglas preferences copyright 1996 by the editors of the scandinavian journal of economics

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

total factor productivity measurement and human capital in oecd countries abstract this paper analyses the total factor productivity tfp evolution in oecd countries by breaking down productivity gains into technical change and efficiency change to avoid biases malmquist indices of productivity including human capital are estimated the results indicate that in fact the inclusion of human capital has a significant effect on the accurate measurement of tfp

identification issues in forward looking models estimated by gmm with an application to the phillips curve limited information methods are commonly used to estimate forward looking models with rational expectations such as the new keynesian phillips curve of gal and gertler 1999 in this paper we address issues of identiflcation that have been overlooked due to the incompleteness of the single equation formulation we show that problems of weak instruments may arise depending on the properties of the exogenous variables and that they are empirically relevant we also uncover a link between identiflcation and dynamic mis speciflcation and examine the lack of power of hansen s 1982 j test to detect invalid over identifying restrictions with regards to the new phillips curve we flnd that problems of identiflcation cannot be ruled out and they deserve further attention

crowdfunding and regional entrepreneurial investment an application of the crowdberkeley database abstract crowdfunding platforms enable individuals to solicit small investments donations or loans over the internet from a wide variety of funders they have emerged as a new and potentially important source of funds for entrepreneurial and philanthropic initiatives we build and present three databases for public use including kickstarter kiva and crowdrise and link regional measures of kickstarter to entrepreneurial ventures listed in crunchbase we find that kickstarter projects in a region correlate with increased angel investing activity even after instrumenting with projects that should not be of interest to investors the paper describes scraping tools database schema descriptive statistics dashboards access for research and policy use and general reflections on building open databases for the research community

risk aversion and wealth evidence from person to person lending portfolios we estimate risk aversion from investors financial decisions in a person to person lending platform we develop a method that obtains a risk aversion parameter from each portfolio choice since the same individuals invest repeatedly we construct a panel data set that we use to disentangle heterogeneity in attitudes toward risk across investors from the elasticity of risk aversion to changes in wealth we find that wealthier investors are more risk averse in the cross section and that investors become more risk averse after a negative housing wealth shock thus investors exhibit preferences consistent with decreasing relative risk aversion and habit formation data as supplemental material are available at http dx doi org 10 1287 mnsc 2015 2317 this paper was accepted by amit seru finance

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

an empirical assessment of optimal monetary policy in the euro area we estimate a new keynesian dsge model for the euro area under alternative descriptions of monetary policy discretion commitment or a simple rule after allowing for markov switching in policy maker preferences and shock volatilities this reveals that there have been several changes in euro area policy making with a strengthening of the anti inflation stance in the early years of the erm which was then lost around the time of german reunification and only recovered following the turmoil in the erm in 1992 the ecb does not appear to have been any more conservative as aggregate euro area policy was under bundesbank leadership the estimates also suggest that the most appropriate description of policy is that of discretion with no evidence of commitment in the euro area as a result although both good luck and good policy played a role in the moderation of inflation and output volatility in the euro area the welfare gains would have been substantially higher had policy makers been able to commit adopting a flexible price level target would lead to outcomes close to commitment

news and financial intermediation in aggregate fluctuations an important disconnect in the news view of fluctuations is the lack of consistent evidence suggestive of significant macroeconomic effects of news shocks findings from estimated dsge models that in theory allow news shocks to matter quantitatively suggest that they do not this disconnect can be resolved once we augment a dsge model with a financial channel that provides amplification to news shocks our results suggest that news shocks to the future growth prospects of the economy are significant drivers of u s fluctuations explaining as much as 50 and 37 of the variance in hours worked and output respectively in cyclical frequencies

does anticipated monetary policy matter an econometric investigation a heated debate has arisen over the policy ineffectiveness proposition associate with the work of lucas sargent and wallace it postulates that anticipated aggregate demand policy will have no effect on business cycle fluctuations so that one deterministic feedback policy rule is as good as any other from the point of view of stabilizing the economy this paper develops a methodology for empirically analyzing rational expectations models displaying this neutrality result and then applies it to the important question of whether anticipated monetary policy matters to the business cycle

the superiority of contingent rules over fixed rules in models with rational expectations the paper investigates the robustness of the proposition that in stochastic models contingent or feddback rules dominate fiped or openloop rules four arguments in favour of fixed rules are considere 1 the presence of an incompetent op malevolent policy maker 2 a trade off between flexibility and simplicity or credibility 3 the new classical proposition that only unanticipated stabilization policy has real effects 4 the time inconsistency of optimal plans in non causal models that is models in which the current state of the economy depends on expectations of future states the main conclusion is that the rational expectations revolution represented by arguments 3 and 4 does not affect the potential superiority of time inconsistent closed loop policies over time inconsistent open loop policies the case against conditionality in the design of policy must therefore rest on argument 1 or 2 which predate the new classical macroeconomics

local identification in dsge models abstract the issue of identification arises whenever structural models are estimated lack of identification means that the empirical implications of some model parameters are either undetectable or indistinguishable from the implications of other parameters therefore identifiability must be verified prior to estimation this paper provides a simple method for conducting local identification analysis in linearized dsge models estimated in both full and limited information settings in addition to establishing which parameters are locally identified and which are not researchers can determine whether the identification failures are due to data limitations such as lack of observations for some variables or whether they are intrinsic to the structure of the model the methodology is illustrated using a medium scale dsge model

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

identification of dsge models the effect of higher order approximation and pruning abstract this paper shows how to check rank criteria for a local identification of nonlinear dsge models given higher order approximations and pruning this approach imposes additional restrictions on higher order moments and polyspectra which can be used to identify parameters that are unidentified in a first order approximation the identification procedures are demonstrated by means of the kim 2003 and the an and schorfheide 2007 models both models are identifiable with a second order approximation furthermore analytical derivatives of unconditional moments cumulants and corresponding polyspectra up to fourth order are derived for the pruned state space

the computational experiment an econometric tool an economic experiment consists of the act of placing people in an environment desired by the experimenter who then records the time paths of their economic behavior performing experiments that use actual people at the level of national economies is obviously not practical but constructing a model economy and computing the economic behavior of the model s people is such experiments are termed computational this essay specifies the steps in designing a computational experiment to address some well posed quantitative question the authors emphasize that the computational experiment is an econometric tool used in the task of deriving the quantitative implications of theory

are elections debt brakes evidence from french municipalities we show that voters are fiscal conservatives although in the long run only while the average over the mandate level of debt has a negative impact on the probability of reelection pre election debt accumulation by incumbents increases their probability of reelection as the negative impact becomes larger as the debt level becomes higher it compensates for the short run effect elections thus appear as a disciplining device even if a weak one

fiscal conservatism in a new democracy sophisticated versus naive voters abstract we use data from gubernatorial elections in brazil to test the electoral reactions of sophisticated and naive voters to fiscal surpluses our results complement brender and drazen brender adi and drazen a 2005b how do budget deficits and economic growth affect reelection prospects evidence from a large cross section of countries nber working paper 11862 national bureau of economic research cambridge massachusetts we find no evidence of fiscal illusion while in some cases a fiscal surplus may actually increase the probability of reelection

unanticipated monetary growth output and the price level u k 1946 1977 abstract this paper develops and estimates using annual data from 1946 1977 a three equation model of the u k economy in which output is affected only by unanticipated monetary growth whereas the price level is influenced by both anticipated and unanticipated changes in money supply expectations of monetary growth are assumed to be muth rational the model was estimated using efficient procedures and tests of the over identifying restrictions were generally favourable to model specification some features of the price equation are unsatisfactory and the results in this section must be considered tentative

opportunistic political cycles test in a young democracy setting this paper tests the theory of opportunistic cycles in a decade old democracy russia finds strong evidence of cycles and provides an explanation for why previous literature often found weaker evidence using regional monthly panel data we find that 1 the budget cycle is sizable and short lived public spending shifts toward direct monetary transfers to voters 2 the magnitude of the cycle decreases with democracy government transparency media freedom voter awareness and over time and 3 preelectoral manipulation increases incumbents chances for reelection the short length of the cycle explains underestimation of its size by previous literature because of low frequency data used in previous studies

the composition of public expenditure and economic growth abstract noting that the literature has focused on the link between the level of public expenditure and growth we derive conditions under which a change in the composition of expenditure leads to a higher steady state growth rate of the economy the conditions depend not just on the physical productivity of the different components of public expenditure but also on the initial shares using data from 43 developing countries over 20 years we show that an increase in the share of current expenditure has positive and statistically significant growth effects by contrast the relationship between the capital component of public expenditure and per capita growth is negative thus seemingly productive expenditures when used in excess could become unproductive these results imply that developing country governments have been misallocating public expenditures in favor of capital expenditures at the expense of current expenditures

access to finance for innovative smes since the financial crisis in the wake of the 2008 financial crisis there has been increased focus on access to finance for small firms research from before the crisis suggested that it was harder for innovative firms to access finance yet no research has considered the differential effect of the crisis on innovative firms this paper addresses this gap using a dataset of over 10 000 uk sme employers we find that innovative firms are more likely to be turned down for finance than other firms and this worsened significantly in the crisis however regressions controlling for a host of firm characteristics show that the worsening in general credit conditions has been more pronounced for non innovative firms with the exception of absolute credit rationing which still remains more severe for innovative firms the results suggest that there are two issues in the financial system the first is a structural problem which restricts access to finance for innovative firms the second is a cyclical problem has been caused by the financial crisis and has impacted relatively more severely on non innovative firms

identification of new keynesian phillips curves from a global perspective this paper is concerned with the estimation of new keynesian phillips curves nkpc and focuses on two issues the weak instrument problem and the characterization of the steady states it proposes some solutions from a global perspective using a global vector autoregressive gvar model steady states are estimated as long horizon expectations and valid instruments are constructed from the global variables as weighted averages the proposed estimation strategy is illustrated using estimates of the nkpc for eight developed industrial countries the gvar generates global factors that are valid instruments and help alleviate the weak instrument problem the steady states also reflect global influences and any long run theoretical relationships that might prevail within and across countries in the global economy the gvar measure of the steady state performed better than the hp measure and the use of foreign instruments substantially increased the precision of the estimates of the output coefficient
