consumption externalities and monetary policy with limited asset market participation this article explores the interaction between consumption externalities and limited asset market participation lamp in the standard new keynesian model we assess the performance of simple taylor type interest rate rules with respect to a equilibrium determinacy b the model s ability to simultaneously generate output and inflation volatility similar to the pre volcker era and c the model s response to a technology shock we find that when individual preferences are affected by average household consumption aggregate consumption externality stronger externalities increase the range of lamp for which multiple equilibria arise even if the policy rule satisfies the taylor principle the interaction of lamp and externalities can generate vast inflation output relative volatility in line with the one observed in the data in the 1970s according to our analysis consumption externalities also affect the responses of endogenous variables to total factor productivity shocks jel e4 e5

relative productivity and search unemployment in an open economy abstract using a panel of eighteen oecd countries we find empirically that the long run effects of higher productivity of tradables relative to non tradables vary across time space and stages of the business cycle more specifically our evidence reveals that elasticities of the relative wage and relative price of non tradables with respect to relative productivity of tradables increase over time our estimates also show that the fall in the relative wage is more pronounced whilst the appreciation in the relative price is less in countries where labor markets are more regulated and during periods of recession to rationalize the evidence we differentiate between labor mobility costs caused by job search efforts and hiring costs resulting from search frictions in the labor market in a two sector open economy model while time declining labor mobility costs can account for the time increasing effects of a productivity differential international differences in labor market regulation and variations of hiring costs across the business cycle respectively can rationalize the cross country and state dependent effects we estimate empirically finally labor market frictions have important implications for sectoral unemployment since labor mobility and hiring costs bias labor demand toward the traded sector which results in a greater decline in unemployment in tradables relative to unemployment in non tradables following higher relative productivity

a labor supply elasticity accord a dispute about the size of the aggregate labor supply elasticity has been fortified by a contentious aggregation theory used by real business cycle theorists the replacement of that aggregation theory with one more congenial to microeconomic observations opens possibilities for an accord about the aggregate labor supply elasticity the new aggregation theory drops features to which empirical microeconomists objected and replaces them with life cycle choices whether the new aggregation theory ultimately indicates a small or large macro labor supply elasticity will depend on how shocks and government institutions interact to put workers at interior solutions for career length

micro and macro elasticities in a life cycle model with taxes we build a life cycle model of labor supply that incorporates changes along both the intensive and extensive margin and use it to assess the consequences of changes in tax and transfer policies on equilibrium hours of work we find that changes in taxes have large aggregate effects on hours of work moreover we find that there is no inconsistency between this result and the empirical finding of small labor elasticities for prime age workers in our model micro and macro elasticities are effectively unrelated our model is also consistent with other cross country patterns

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

implications of increasing college attainment for aging in general equilibrium we develop an overlapping generations general equilibrium model of the u s economy with heterogeneous consumers who face idiosyncratic earnings and health risk to study the implications of increasing college attainment decreasing fertility and increasing longevity 2005 2100 while all three trends contribute to a higher old age dependency ratio increasing college attainment has different implications because it increases labor productivity decreasing fertility and increasing longevity require the government to increase the average labor tax rate from 33 5 to 47 1 percent increasing college attainment lowers the required tax increase by 12 0 percentage points the labor tax rate required to balance the government budget is higher under general equilibrium than in a small open economy with a constant interest rate because the reduction in the interest rate lowers capital income tax revenues

iceland s natural experiment in supply side economics the move to a pay as you earn income tax system in iceland in 1987 1988 made income earned in 1987 tax free using a sample of 9 274 individuals for the years 1986 1987 and 1988 we calculate the labour supply response of this change and find that total labour supply rose by 6 7 in 1987 over the average of 1986 and 1988 when we correct for entry in 1988 this consists of an 8 6 increase in weeks supplied by those already in the labour market in 1986 and a 1 9 decline due to entry exit the elasticity of weeks worked to the rise in after tax wages was 0 41 for men and 0 11 for women while the participation rate of women increased somewhat in our sample participation by men fell this abstract was borrowed from another version of this item

discretionary monetary and fiscal policy with endogenous sovereign risk abstract how does the presence of sovereign risk affect the conduct of public policy to answer this question this paper studies optimal monetary and fiscal policy without commitment for a model economy with nominal public debt and strategic sovereign default compared to an economy without the possibility of default economies with sovereign risk experience more volatile interest rates which impedes the government s ability to smooth tax rates across states risk of default also limits public debt accumulation reducing the government s incentive to use surprise inflation on average when calibrated to the united states the model predicts that a counterfactual increase in the average annual default probability from 0 to 1 lowers average inflation by 33 raises the standard deviation of inflation by 18 and increases the standard deviation of the labor income tax by 73 the transmission of exogenous shocks to real aggregate quantities is however almost unaffected by the possibility of default for example the presence of sovereign risk would increase the standard deviation of log real gdp by less than 1 in the experiment above similarly the welfare consequences of sovereign risk are found to be of negligible size as well

lack of divine coincidence in new keynesian models abstract the literature has long agreed that the divine coincidence holds in standard new keynesian models the monetary authority is able to simultaneously stabilize inflation and output gap in response to preference and technology shocks i show that the divine coincidence holds only when inflation is stabilized at exactly zero even small deviations from zero generate policy trade offs i demonstrate this result using the model s non linear equilibrium conditions to avoid biases from log linearization when the model is log linearized a non zero steady state level of inflation gives rise to what i call the endogenous trend inflation cost push shock in the new keynesian phillips curve

are micro and macro labor supply elasticities consistent a review of evidence on the intensive and extensive margins we evaluate whether state of the art macro models featuring indivisible labor are consistent with modern quasi experimental micro evidence by synthesizing evidence on both the intensive and extensive margins we find that micro estimates are consistent with macro estimates of the steady state hicksian elasticities relevant for cross country comparisons on both the extensive and intensive margins however micro estimates of intertemporal substitution frisch elasticities are an order of magnitude smaller than the values needed to explain business cycle fluctuations in aggregate hours by preferences the key puzzle to be resolved is why micro and macro estimates of the frisch extensive margin elasticity are so different

worktime regulations and spousal labor supply we study interdependencies in spousal labor supply by exploiting the design of the french workweek reduction which introduced exogenous variation in one s spouse s labor supply at constant earnings treated employees work on average two hours less per week husbands of treated women respond by reducing their labor supply by about half an hour consistent with substantial leisure complementarity and specifically cut the non usual component of their workweek leaving usual hours unchanged women s response to their husband s treatment is instead weak and rarely statistically significant possibly due to heavier constraints in the organization of their workweek

technical change wage inequality and taxes this paper considers the normative implications of technical change for tax policy design a task to talent assignment model of the labor market is embedded into an optimal tax problem technical change modifies equilibrium wage growth across talents and the substitutability of talents across tasks the overall optimal policy response is to reduce marginal income taxes on low to middle incomes while raising those on middle to high incomes the reform favors those in the middle of the income distribution reducing their average taxes while lowering transfers to those at the bottom jel d31 h21 h23 h24 j31 o33

the uncertainty multiplier and business cycles abstract i study a business cycle model where agents learn about the fundamentals by accumulating capital during recessions agents invest less and this generates noisier estimates of macroeconomic conditions and an increase in uncertainty the endogenous increase in aggregate uncertainty further reduces economic activity and thus gives rise to a multiplier effect that amplifies aggregate fluctuations to discipline learning dynamics i parametrize the model so that it matches not only standard business cycle moments but also survey data on macroeconomic forecasts i find that the uncertainty multiplier amplifies output standard deviation by 16

towards a micro founded theory of aggregate labour supply we build a heterogeneous agents life cycle model that captures a large number of salient features of individual male labour supply over the life cycle by education both along the intensive and extensive margins the model provides an aggregation theory of individual labour supply firmly grounded on individual level micro evidence and is used to study the aggregate labour supply responses to changes in the economic environment we find that the aggregate labour supply elasticity to a transitory wage shock is 1 75 with the extensive margin accounting for 62 of the response furthermore we find that the aggregate labour supply elasticity to a permanent compensated wage change is 0 44

unlocking the gates of paradise general equilibrium effects of information exchange abstract in a move to reduce bank secrecy and fight international tax evasion about 100 tax jurisdictions have so far committed to implement a new standard on the automatic exchange of information aeoi this paper examines the quantitative consequences of the aeoi for an onshore country using a neoclassical model with an offshore financial center our main findings are i the aeoi increases government revenues but reduces welfare ii welfare improves when using the aeoi revenues to reduce tax pressure or when including household wealth inequality iii government revenues increase further when accounting for a disclosure penalty cost these results depend on the general equilibrium effects absent from earlier papers on offshore financial centers

labor supply and the extensive margin forty years ago the french and british used to work more than the americans they now work less the aim of this paper is to provide a coher ent picture of these changes to do so we split the overall level of work activity into the number of individuals in work and the intensity of work supplied by those in work this reflects the dis tinction between whether to work and how much to work at the individual level this is referred to respectively as the extensive and intensive mar gin of labor supply the difference between the extensive and intensive margins has been highlighted in recent research attempting to resolve differ

optimal monetary policy with international trade in intermediate inputs abstract this paper examines optimal monetary policy in a two country new keynesian model with international trade in intermediate inputs we derive the loss function of a cooperative monetary policymaker and find that the optimal monetary policy must target intermediate goods price inflation rates final goods price inflation rates final goods output gaps and relative price gaps we use the welfare loss under the optimal monetary policy as a benchmark to evaluate the welfare implications of three taylor type monetary policy rules a main finding is that the degree of price stickiness at the stage of intermediate goods production is a key factor to determine which policy rule should be followed specifically when the degree of price stickiness at the stage of intermediate goods production is high the policymaker should follow intermediate goods ppi based taylor rule whereas cpi based taylor rule should be followed when the degree of price stickiness at the stage of intermediate goods production is intermediate or low

the aggregate implications of regional business cycles during the last recession and its aftermath aggregate price growth and aggregate nominal wage growth remained robust despite the high rate of unemployment we document that u s states with weaker labor markets experienced lower price growth lower nominal wage growth and lower real wage growth during the great recession given that reliable measures of local prices do not exist we create our own state price indices using scanner data from the nielsen retail scanner database the main innovation of the paper is the development of an econometric procedure that combines cross region data with aggregate time series data to infer the underlying shocks driving both aggregate and regional business cycles applying our procedure to the great recession we find that a combination of both demand and supply shocks are necessary to account for the joint dynamics of aggregate prices wages and employment during the 2007 2012 period in contrast we find that only demand shocks are needed to explain the cross region variation the results suggest that only using cross region variation to explain aggregate fluctuations is insufficient when shocks do not have a substantive regional component

the credit channel transmission mechanism and the nonlinear growth and welfare effects of inflation and taxes with the credit channel effect driven by the central bank s open market operations this paper s model easily gives rise to the nonlinear inflation growth nexus which is evidenced by a number of cross country empirical studies the threshold level of the inflation rate is found to be lower when tax rates are higher the presence of the credit channel effect also provides the rationale for setting positive and smaller than 1 tax rates on consumption labor income and capital income the optimal tax rates rise as the inflation target declines under a fiscal policy rule where labor and capital income taxes move proportionally to each other the optimal capital income tax rate could be higher than the optimal labor income tax rate under a sufficiently large central bank balance sheet the credit channel effect will be so weak that inflation and all kinds of taxes are growth and welfare repressing this provides a rationale for central banks that have implemented quantitative easing policies to shrink their balance sheets jel e58 e62 o42

labor supply in the past present and future a balanced growth perspective the absence of a trend in hours worked in the postwar united states is an exception across countries and historically hours fall steadily by a little below 0 5 per year are steadily falling hou

employment and hours over the business cycle abstract approximately one quarter of the adjustment in total hours of employment over the business cycle represents adjustments in hours while the remainder is explained by changes in employment real business cycle models characterize agents as either continuously adjusting their hours or making only labor force participation decisions about jobs with indivisible hours in this paper we extend the representative agent framework to allow for decisions on both participation and hours we calibrate and simulate a dynamic version of the model and show that it is better able to mimic some features of the aggregate data

asset pricing and the propagation of macroeconomic shocks this paper considers the implications of habit formation and financial frictions for the propagation of macroeconomic shocks in a model that is capable of matching asset pricing moments a short lived shock that destroys a small fraction of the economy s stock of pledgeable collateral generates a persistent recession a stock market crash and a flight to safety effect this novel mechanism creates a tight link between the asset pricing implications of macroeconomic models and their ability to propagate and amplify the effects of macroeconomic shocks

natural resources and economic growth a meta analysis summary an important question in development studies is how natural resources richness affects long term economic growth no consensus answer however has yet emerged with approximately 40 of empirical papers finding a negative effect 40 finding no effect and 20 finding a positive effect does the literature taken together imply the existence of the so called natural resource curse in a quantitative survey of 605 estimates reported in 43 studies we find that overall support for the resource curse hypothesis is weak when potential publication bias and method heterogeneity are taken into account our results also suggest that four aspects of study design are especially effective in explaining the differences in results across studies 1 controlling for institutional quality 2 controlling for the level of investment activity 3 distinguishing between different types of natural resources and 4 differentiating between resource dependence and abundance

welfare gains of bailouts in a sovereign default model abstract we examine the welfare effects of bailouts in economies exposed to sovereign default risk when a government of a small open economy requests a bailout from an international financial institution it receives a non defaultable loan of size g that comes with imposed debt limits the government endogenously asks for the bailout during recessions and repays it when the economy recovers hence the bailout acts as an imperfect state contingent asset that makes the economy better off the bailout duration is endogenous and increases with its size the bailout size creates non trivial tradeoffs between receiving a larger amount of relatively cheap resources precisely in times of need on the one hand and facing longer lasting financial constraints and accumulated interest payments on the other hand we characterize and quantify these tradeoffs and document that welfare gains of bailouts are hump shaped in the size of bailout loans

inattentive consumers and international business cycles this paper presents and studies the properties of a sticky information exchange rate model where consumers and producers update their information sets infrequently introducing inattentive consumers has important implications through a mechanism resembling the limited participation models exchange rate volatility observed in the data can be addressed for reasonable values of risk aversion the model generates more persistence in output consumption and employment which brings us closer to the data impulse responses to monetary shocks are hump shaped consistent with the empirical evidence forecast errors of inattentive consumers provide a channel to reduce the correlation of relative consumption and real exchange rate the decline in the correlation is quantitatively small for our benchmark model model generates a substantial amount of consumer forecast errors when producers are attentive and productivity shocks are persistent this specification results in a large decline of the correlation of real exchange rate and relative consumption due to consumer inattentiveness when trade elasticity is set to values at the low end of macro estimates or at higher values consistent with sectoral estimates the correlation is in the negative territory with inattentive consumers

do place based tax incentives create jobs abstract in this paper we evaluate the effectiveness of place based payroll taxes in stimulating local employment by exploiting a unique policy setting in norway where a system of geographically differentiated payroll taxes was suddenly abolished due to an eu regulation the reform was enforced independently of the regional labor market developments creating arguably exogenous variation in the payroll tax rates that firms in different local labor markets faced over time we find evidence of partial shifting of payroll tax increases on to worker wages as well as a significant decline in local employment these findings suggest that in settings with some degrees of wage rigidity place based payroll tax incentives can be effective in stimulating local employment

information acquisition and welfare we study information acquisition in a flexible framework with strategic complementarity or substitutability in actions and a rich set of externalities that are responsible for possible wedges between the equilibrium and the efficient acquisition of information first we relate the in efficiency in the acquisition of information to the in efficiency in the use of information and explain why efficiency in the use is no guarantee of efficiency in the acquisition next we show how the acquisition of private information affects the social value of public information i e the comparative statics of equilibrium welfare with respect to the quality of public information finally we illustrate the implications of the results in a monetary economy with price rigidities and dispersed information about productivity shocks

monetary policy tradeoffs between financial stability and price stability we analyze the impact of interest rate policy on financial stability in an environment where banks can experience runs on their short term liabilities forcing them to sell assets at fire sale prices

anticipated and unanticipated wage changes wage risk and intertemporal labor supply in this article i estimate how labor supply responds to anticipated wage growth unanticipated wage growth and wage risk using the 1989 93 panel section of the bank of italy survey of households income and wealth shiw which collects individual expectations of future wages the use of subjective expectations has several advantages first they provide information on the evolution and riskiness of future wages that the econometrician may never hope to observe moreover this avoids the need for specifying instruments for the growth rate of wages finally forecast errors can be directly controlled for thus avoiding inconsistency in short panels

the limits of inference with theory a review of wolpin 2013 this essay reviews kenneth i wolpin s 2013 monograph the limits of inference without theory which arose from lectures he presented at the cowles foundation in 2010 in honor of tjalling koopmans while i readily agree with wolpin s basic premise that empirical work that eschews the role of economic theory faces unnecessary self imposed limits relative to empirical work that embraces and tries to test and improve economic theory it is important to be aware that the use of economic theory is not a panacea i point out that there are also serious limits to inference with theory 1 there may be no truly structural policy invariant parameters a key assumption underpinning the structural econometric approach that wolpin and the cowles foundation have championed 2 there is a curse of dimensionality that makes it very difficult for us to elucidate the detailed implications of economic theo ries which is necessary to empirically implement and test these theories 3 there is an identification problem that makes it impossible to decide between competing theories without imposing ad hoc auxiliary assumptions such as parametric functional form assumptions and 4 there is a problem of multiplicity and indeterminacy of equilibria that limits the predictive empirical content of many economic theories i conclude that though these are very challenging problems i agree with wolpin and the cowles foundation that economists have far more to gain by trying to incorporate economic theory into empirical work and test and improve our theories than by rejecting theory and presuming that all interesting economic issues can be answered by well designed controlled randomized experiments and assuming that difficult questions of causality and evaluation of alternative hypothetical policies can be resolved by simply allowing the data to speak for itself jel b41 c18

optimal dynamic carbon taxes in a climate economy model with distortionary fiscal policy how should carbon be taxed as a part of fiscal policy the literature on optimal carbon pricing often abstracts from other taxes however when governments raise revenues with distortionary taxes carbon levies have fiscal impacts while they raise revenues directly they may shrink the bases of other taxes e g by decreasing employment this article theoretically characterizes and then quantifies optimal carbon taxes in a dynamic general equilibrium climate economy model with distortionary fiscal policy first this article establishes a novel theoretical relationship between the optimal taxation of carbon and of capital income this link arises because carbon emissions destroy natural capital they accumulate in the atmosphere and decrease future output consequently this article shows how the standard logic against capital income taxes extends to distortions on environmental capital investments second this article characterizes optimal climate policy in sub optimal fiscal settings where income taxes are constrained to remain at their observed levels third this article presents a detailed calibration that builds on the seminal dice approach but adds features essential for a setting with distortionary taxes such as a differentiation between climate change production impacts e g on agriculture and direct utility impacts e g on biodiversity existence value the central quantitative finding is that optimal carbon tax schedules are 8 24 lower when there are distortionary taxes compared to the setting with lump sum taxes considered in the literature

monetary policy trend inflation and unemployment volatility the literature has long agreed that the dmp model after diamond 1982 mortensen 1982 pissarides 1985 with search and matching frictions in the labor market can deliver large volatilities in labor market quantities consistent with empirical data only if there is at least some wage stickiness i show however that the model can deliver nontrivial volatilities without wage stickiness as long as it has price dispersion and nonzero long run inflation rates i find that by keeping inflation at a positive rate monetary policy may be accountable for the large standard deviations observed on labor market variables in addition the shimer 2005 puzzle disappears under monetary policy shocks

the distributional consequences of tax reforms under capital skill complementarity this paper analyses wage inequality and the welfare effects of changes in capital and labour income tax rates for different types of agents to achieve this we develop a model that allows for capital skill complementarity given non uniform distributions of asset holdings and labour skills we find that capital tax reductions lead to the highest aggregate welfare gains but are skill biased and thus increase inequality however our analysis also shows that the inequality effects of capital tax reductions are lower over the transition period compared with the long run

heterogeneous beliefs and housing market boom bust cycles abstract this paper presents a business cycle model capturing the stylized features of housing market boom bust cycles in developed countries the model implies that over optimism of mortgage borrowers generates housing market boom bust cycles if mortgage borrowers are credit constrained and savers do not share their optimism this result holds without price stickiness if price stickiness is introduced into the model then the model replicates a low policy interest rate during a housing boom as an endogenous reaction to a low inflation rate given a taylor rule thus monetary easing observed during housing booms are consistent with the presence of over optimism causing boom bust cycles

adjustment costs firm responses and micro vs macro labor supply elasticities evidence from danish tax records we show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms we develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs we present evidence supporting three predictions of this model by analyzing bunching at kinks using danish tax records first larger kinks generate larger taxable income elasticities second kinks that apply to a larger group of workers generate larger elasticities third the distribution of job offers is tailored to match workers aggregate tax preferences in equilibrium our results suggest that macro elasticities may be substantially larger than the estimates obtained using standard microeconometric methods

wages youth employment and school enrollment recent evidence from increases in world oil prices we exploit variation in wage growth induced by increases in world oil prices to estimate the elasticity of young men s labor market participation and school enrollment with respect to after tax wages our main finding is that in the aggregate increased wages have a dual impact they tend to reduce at least temporarily young men s full time university enrollment rates but bring back into the labor market some young men who were neither enrolled in school nor employed contrary to previous research we find little evidence that young men with no high school diploma now leave school in response to increased wages

inflation default and sovereign debt the role of denomination and ownership abstract emerging market governments hold mixed debt portfolios they borrow at home and abroad in both nominal and real terms this paper incorporates such a mixed debt structure into a theory of sovereign debt default and inflation the government optimally uses both default and inflation to balance its budget the portfolio structure affects the relative benefits of inflation default and incentives to accumulate debt a calibrated version of the model can account for key features of the mexican economy we use the model to study if portfolio shifts away from purely real and external debt contributed to emerging market disinflation in the mid 1990s we find that the answer depends on the distinction between ownership and denomination increasingly nominal debt is inflationary if held abroad but lowers inflation if held at home

german wage moderation and european imbalances feeding the global var with theory german labor market reforms in the 1990s and 2000s are generally believed to have driven the large increase in the dispersion of current account balances in the euro area we investigate this hypothesis quantitatively we develop a 3 region open economy new keynesian model with search and matching frictions from which we derive robust sign restrictions for wage bargaining and matching efficiency shocks which we term wage moderation shocks we impose these restrictions on a global var consisting of germany and 8 emu countries to identify a wage moderation shock in germany our results show that although the german current account was significantly affected by wage moderation shocks their contribution to european current account imbalances was negligible we conclude that the german labor market reforms cannot be the lone driver of european imbalances

external financing and the role of financial frictions over the business cycle measurement and theory we examine the quantitative importance of financial market shocks in accounting for business cycle fluctuations we emphasize the role financial markets play in reallocating funds from cash rich low productivity firms to cash poor high productivity firms using evidence on financial flows at the firm level we find that for publicly traded firms in compustat almost all investment is financed internally however using an alternative data source amadeus we find that most investment by privately held firms is financed through borrowing motivated by these observations we build a quantitative model featuring publicly and privately held firms that face collateral constraints and idiosyncratic risk over productivity as well as non financial linkages in our calibrated model we find that a shock to the collateral constraints which generates a one standard deviation decline in the debt to asset ratio leads to a 0 5 decline in aggregate output on impact roughly comparable to the effect of a one standard deviation shock to aggregate productivity in a standard real business cycle model in this sense we find that disturbances in financial markets are a promising source of business cycle fluctuations when non financial linkages across firms are sufficiently strong

identifying laffer bounds a sufficient statistics approach with an application to germany we derive a simple sufficient statistics test for whether a nonlinear tax transfer system is second best pareto efficient if it is not then it is beyond the top of the laffer curve and there exists a tax cut that is self financing the test depends on the income distribution extensive and intensive labor supply elasticities and income effect parameters a tax transfer system is likely to be inefficient if marginal tax rates are quickly falling in income we apply this test to the german tax transfer system and we find that the structure of effective marginal tax rates is likely to be inefficient in the region where transfers are phased out

liquidity shocks business cycles and asset prices abstract in the aftermath of the great recession macro models that feature financing constraints have attracted increasing attention among these kiyotaki et al 2012 is a prominent example in this paper we investigate whether the liquidity shocks and financial frictions proposed by kiyotaki et al 2012 can improve the asset pricing predictions of the frictionless rbc model we study the quantitative business cycle and asset pricing properties in an economy in which agents feature recursive preferences are subject to a liquidity constraint and suffer liquidity shocks we find that the model predicts highly nonlinear time variation and levels of risk premia which are driven by endogenous fluctuations in equity prices however the model fails to account for a basic fact periods of scarce liquidity are associated with high asset prices and low expected returns

pension reform and labor supply abstract we exploit a comprehensive restructuring of the early retirement system in norway in 2011 to examine labor supply responses to increases in work incentives and actuarially neutral reductions in the age of first access to pension benefits we find that increasing the returns to work is a powerful policy the removal of an earnings test implying a doubling of the average net take home wage led to an increase in average labor supply by 7 h per week 30 at age 63 and by 8 h 46 at age 64 the responses primarily came at the extensive margin in contrast reducing the access age has almost no effect on labor supply in our setting with actuarially fair work incentives

self employment in the developing world summary this paper analyzes heterogeneity among the self employed in 74 developing countries representing two thirds of the population of the developing world after profiling how worker characteristics vary by employment status it classifies self employed workers outside agriculture as successful or unsuccessful entrepreneurs based on two measures of success whether the worker is an employer and whether the worker resides in a non poor household four main findings emerge first jobs exhibit a clear pecking order with household income and worker education highest for employers followed by wage and salaried employees non agricultural own account workers non agricultural unpaid family workers and finally agricultural workers second a substantial minority of own account workers reside in non poor households suggesting that their profits are often a secondary source of household income third as per capita income increases across countries the structure of employment shifts rapidly first out of agriculture into unsuccessful non agricultural self employment and then mainly into non agricultural wage employment finally roughly one third of the unsuccessful entrepreneurs share similar characteristics with their successful counterparts suggesting they have the potential to be successful but face constraints to growth the authors conclude that although interventions such as access to credit can benefit a substantial portion of the self employed effectively targeting the minority of self employed with higher growth potential is important particularly in low income contexts the results also highlight the potential benefits of policies that facilitate shifts in the nature of work first from agricultural labor into non agricultural self employment and then into wage and salaried jobs

methods versus substance measuring the effects of technology shocks abstract calibration and modern bayesian estimation methods for a neoclassical stochastic growth model are applied to make the case that the identification of key parameters rather than quantitative methodologies per se is responsible for empirical findings for concreteness the model is used to measure the contributions of technology shocks to the business cycle fluctuations of hours worked and output along the way new insights are provided in the parameter identification associated with likelihood based estimation the sensitivity of likelihood based estimation to the choice of structural shocks is assessed and bayesian model averaging is used to aggregate findings obtained from different dsge model specifications
