income inequality and growth does the relationship vary with the income level abstract for three different specifications of a cross country growth model the coefficient of initial income inequality is remarkably similar for high and low income countries contrary to some recent suggestions in the literature but varies markedly across models

price setting during low and high inflation evidence from mexico this paper provides new insight into the relationship between inflation and the setting of individual prices by examining a large data set of mexican consumer prices covering episodes of both low and high inflation when the annual rate of inflation is low below 10 15 the frequency of price changes comoves weakly with inflation because movements in the frequency of price decreases and increases partly offset each other in contrast the average magnitude of price changes correlates strongly with inflation because it is sensitive to movements in the relative shares of price increases and decreases when inflation rises beyond 10 15 few price decreases are observed and both the frequency and average magnitude are important determinants of inflation i show that a menu cost model with idiosyncratic technology shocks predicts the average frequency and magnitude of price changes well over a range of inflation similar to that experienced by mexico

inequality in the globalizing asia this article investigates the impact of globalization on the inequality of asia it is the first attempt to examine 11 asian countries panel data allowing nonlinearity between globalization and inequality from 1960 to 2003 with robustness check we also survey the literature on growth globalization and inequality and reflect their endogenous relationships to our article we found the significant turning point of globalization at which inequality starts decreasing as further globalization proceeds it will offer us policy implications for the ongoing process of globalization in the asian economies

development and inequality revisited three decades after the seminal article of kuznets 1955 and one decade after the empirical investigation of ahluwalia 1976b the relationship between income inequality and economic developement is still controversial this paper examines the above relationship within a time series cross section framework in a sample of countries which are representative of the non centrally planned economies of the world we use gdp per capita in real un international comparison project dollors as an indicator of a country s level of economic development the results lend support to the kuznets inverse u hypothesis although other factors relfecting the institutional setting of a country are found to affect income inequality significantly during the development process as well similar results are obtained if we exclude developed countries from the sample

inflation and welfare in a monetary economy it is in everyone s private interest to try to get someone else to hold non interest bearing cash and reserves but someone has to hold it all so these efforts must simply cancel out all of us spend several hours per year in this effort and employ thousands of talented and highly trained people to help us these person hours are simply thrown away wasted on a task that should not have to be performed at all

refitting the kuznets curve abstract using baltagi and li 2002 s semi parametric fixed effects regression estimator we investigate the existence of an aggregate kuznets curve in a sample of 113 countries over the 1960 2000 period our results show that misspecification of the functional form in a panel model with fixed effects and the failure to control for the endogeneity of income per capita can lead to dramatically different conclusions regarding the impact of economic development on inequality while we find observational evidence of an inverted u relationship between inequality and economic development this relationship does not seem to be causal once we account for endogeneity inequality appears to decrease monotonically with income per capita

energy conservation investment do consumers discount the future correctly we argue that the apparently high discount rates attributed to investors making energy conservation investments are not irrational or the result of some market failure rather they may result from an investor recognizing that many conservation investments entail substantial sunk costs in the presence of these costs and uncertainty over future conservation savings consumers should use a higher hurdle rate for investment than if there were no uncertainty simulations suggest that the hurdle rate should be about four times greater than the standard rate an implication of our model is that tax subsidies for the purchase of conservation capital are likely to be ineffective we discuss alternative policy approaches which are more likely to increase energy efficient investment namely mandatory efficiency standards and energy taxes

is inequality harmful for growth comment endogenous growth models have reignited interest in institutional and path dependencies in the economic growth process one reason for the interest in endogenous growth models is that they may explain why countries consistently grow at different rates in this vein it has been recently proposed that greater economic inequality reduces future economic growth an important paper in this literature is by torsten persson and guido tabellini 1994 who will be referred to as pt pt s model shows why it is reasonable to expect a negative relationship between inequality and future economic growth moreover their empirical evidence is consistent with their contention if pt s findings are robust to other data sets there would be important policy implications for example they imply that policy makers should not only be concerned with the distributional implications of government policies for political and social reasons but also because income distribution has long run effects on economic growth this indicates that greater u s income inequality since the early 1970 s may have resulted in lower subsequent economic growth however pt s results are somewhat fragile to various specifications suggesting that they should be replicated with different data sets and over different time periods pt p 617 with these implications in mind this study employs data from a panel of u s states to further explore the relationship between economic growth and income inequality in what follows section i summarizes pt s study and discusses how this comment extends their findings the empirical implementation and results in section ii directly examine the link between overall income inequality and growth section iii expands the analysis to alternative measures of income distribution and government policy one emphasis in section iii is the distinction between how the overall income distribution especially at the tails influences economic growth from how the relative well being of the median voter affects economic growth section iv provides some concluding discussion

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

menu costs and phillips curves this paper develops a model of a monetary economy in which individual firms are subject to idiosyncratic productivity shocks as well as general inflation sellers can change price only by incurring a real menu cost we calibrate this cost and the variance and autocorrelation of the idiosyncratic shock using a new u s data set of individual prices due to klenow and kryvtsov the prediction of the calibrated model for the effects of high inflation on the frequency of price changes accords well with international evidence from various studies the model is also used to conduct numerical experiments on the economy s response to various shocks in none of the simulations we conducted did monetary shocks induce large or persistent real responses

the small sample bias of the gini coefficient results and implications for empirical research the gini coefficient is a downward biased measure of inequality in small populations when income is generated by one of three common distributions the paper discusses the sources of bias and argues that this property is far more general this has implications for i the comparison of inequality among subsamples some of which may be small and ii the use of the gini in measuring firm size inequality in markets with a small number of firms the small sample bias has often led to misperceptions about trends in industry concentration a small sample adjustment results in a reduced bias which can no longer be signed this remaining bias rises with the dispersion and falls with increasing skewness of the distribution finally an empirical example illustrates the importance of using the adjusted gini in this example it is shown that controlling for market characteristics larger shipping cartels include a set of firms that is stochastically identical in terms of relative size to those of smaller shipp

revisiting external imbalances insights from sectoral accounts abstract this paper revisits the period of substantial widening of external imbalances in advanced economies in the run up to the global financial crisis and their adjustment since then we take a granular look at these imbalances through the lens of their domestic counterpart the net financial balance of the household sector the government non financial corporations and financial corporations our findings challenge the often claimed view that the household sector lies behind most of the dynamics of the current account in fact we show that it is non financial corporations and the government that account for the bulk of i the co movement with the standard set of fundamental covariates of the current account ii the external adjustment and expenditure reduction in the aftermath of the global financial crisis and iii the diverging dynamics during large and persistent current account imbalances these results emphasize that analyzing domestic sectoral balances can lead to a better empirical and theoretical understanding of global imbalances

the return of patrimonial capitalism a review of thomas piketty s capital in the twenty first century capital in the twenty first century by thomas piketty provides a unified theory of the functioning of the capitalist economy by linking theories of economic growth and functional and personal income distributions it argues based on the long run historical data series that the forces of economic divergence including rising income inequality tend to dominate in capitalism it regards the twentieth century as an exception to this rule and proposes policies that would make capitalism sustainable in the twenty first century jel d31 d33 e25 n10 n30 p16

growth of regional economy and income inequality county level evidence from florida usa the purpose of this paper is to find the homogeneous groups and growth factors of florida s counties through factor analysis and cluster analysis from data sets from 1979 and 2000 and to grasp the relationship between income inequality and growth by cluster using the derived growth factors the numbers of factors divided through factor analysis were three and six groups were obtained from cluster analysis 1 the theoretical background for choosing this particular value is that a factor must have a variance at least as large as that of a single standardized original variable county level evidence of this paper indicates that gi di and sin have a strong effect and are statistically significant to the growth rate results for income inequality by county and region indicate significant differences between counties including counties where agriculture accomplishes the primary main function therefore government should adopt the following policies minimum wage unemployment insurance local or state tax po

pareto and piketty the macroeconomics of top income and wealth inequality abstract since the early 2000s research by thomas piketty emmanuel saez and their coauthors has revolutionized our understanding of income and wealth inequality in this paper i highlight some of the key empirical facts from this research and comment on how they relate to macroeconomics and to economic theory more generally one of the key links between data and theory is the pareto distribution the paper describes simple mechanisms that give rise to pareto distributions for income and wealth and considers the economic forces that influence top inequality over time and across countries for example it is in this context that the role of the famous r g expression is best understood

regional income effects and renewable fuels increased usage of renewable energy sources in danish rural areas and its impact on regional incomes co2 emission is a worldwide problem and in the attempt to reduce these emissions renewable energy sources may be considered serious alternatives to the present usage of fossil fuels as part of a research programme financed by the danish energy agency data concerning the different heating technologies based on oil and wood fuels have been collected private and social costs are estimated and these economic data are used when analysing regional income effects of increased consumption of fuels e g wood locally produced the impacts on income and tax revenues are calculated from multiplier expressions constructed with rights to the measurement of local effects

income inequality and economic development evidence from the threshold regression model abstract using panel data we investigate the relationship between income inequality and economic development we employ a threshold regression model that allows for endogenous income thresholds and find strong evidence of a two regime split in our sample

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

intermediate goods and business cycles implications for productivity and welfare this paper presents an aggregate demand driven model of business cycles that provides a new explanation for the procyclicality of productivity and simultaneously predicts large welfare losses from monetary nonneutrality the key features of the model are an input output production structure imperfect competition countercyclical markups and for some results state dependent price rigidity true technical efficiency is procyclical even though production takes place with constant returns without technology shocks or technological externalities the paper has observable implications that distinguish it empirically from related work these implications are generally supported by data from u s manufacturing industries copyright 1995 by american economic association

do consumers discount the future correctly a market based valuation of residential fuel switching abstract dsm and energy efficiency options are generally evaluated using engineering oriented discounted cash flow procedures which value all cost and benefit streams using a single arbitrary discount rate usually the firm s weighted average cost of capital wacc the wacc based approach ignores financial risk and hence leads to unreliable results in a recent paper in this journal hassett and metcalf depart from this tradition they reflect financial risk by simulating the total variability of returns from energy saving investments their findings indicate that dsm projects are potentially risky suggesting that the net benefits must be discounted at significantly higher rates thus lowering their present values this paper presents a market based evaluation of a particular dsm option residential fuel switching using the capital asset pricing model capm under the capm approach a risk adjusted market based discount rate is estimated for each cost stream fuel maintenance and avoided outlays for electricity the market based results which reflect the systematic risk of each cost stream suggest that fuel switching is probably not cost effective because it is considerably more risky than indicated by a wacc based analysis this supports hassett and metcalf s conclusion that consumers who reject dsm projects are not necessarily acting irrationally

refitting the kuznets curve using a gender specific threshold model abstractprevious studies have reached mixed conclusions regarding the relationship between inequality and per capita income these studies however fail to consider gender differences in income inequality and how these may impact on the relationship between income inequality and per capita income using australian taxation statistics we derive three sets of gini coefficients i e female male and total for the period 1950 2013 we then examine the relationship between inequality and real per capita income and find that a gender specific threshold panel regression outperforms three other conventional models our findings suggest that one set of coefficients does not fit all in that the use of aggregate and constant coefficients may mask variations within and between gender inequality over time

a unified framework for monetary theory and policy analysis search theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential however tractable versions of these models typically make strong assumptions that render them ill suited for monetary policy analysis we propose a new framework based on explicit micro foundations within which macro policy can be studied the framework is analytically tractable and easily quantifiable we calibrate the model to standard observations and use it to measure the cost of inflation we find that going from 10 percent to 0 percent inflation is worth between 3 and 5 percent of consumption much higher than previous estimates

optimal lending contracts and firm dynamics we develop a general model of lending in the presence of endogenous borrowing constraints borrowing constraints arise because borrowers face limited liability and debt repayment cannot be perfectly enforced in the model the dynamics of debt are closely linked with the dynamics of borrowing constraints in fact borrowing constraints must satisfy a dynamic consistency requirement the value of outstanding debt restricts current access to short term capital but is itself determined by future access to credit this dynamic consistency is not guaranteed in models of exogenous borrowing constraints where the ability to raise short term capital is limited by some prespecified function of debt we characterize the optimal default free contract which minimizes borrowing constraints at all histories and derive implications for firm growth survival leverage and debt maturity the model is qualitatively consistent with stylized facts on the growth and survival of firms comparative statics with respect to technology and default constraints are derived borrowing constraints are an important determinant of firm growth and survival 1 such constraints may arise in connection to the financing of investment opportunities faced by firms or temporary liquidity needs such as those required to survive a recession this paper develops a theory of endogenous borrowing constraints and studies its implications for firm dynamics in our model debt is constrained by the firm s limited liability and option to default a lending contract specifies an initial loan size future financing and a repayment schedule the choice of these variables in turn determines future growth the firm s future borrowing capacity and its ability and willingness to repay hence borrowing constraints and firm dynamics are jointly determined we study this dynamic design problem our model builds on thomas and worral s 1994 model of foreign direct investment at time zero a risk neutral borrower firm or entrepreneur has a project which requires a fixed initial set up cost every period the project yields revenues that increase with the amount of 1 there is considerable evidence suggesting that financing constraints are important determinants of firm dynamics gertler and gilchrist 1994 argue that liquidity constraints may explain why small manufacturing firms respond more to a tightening of monetary policy than do larger manufacturing firms perez quiros and timmermann 2000 show that in recessions smaller firms are more sensitive to the worsening of credit market conditions as measured by higher interest rates and default premia evans and jovanovic 1989 show that the liquidity constraints are essential in the decision to become an entrepreneur fazzari hubbard and petersen 1988 among others view financial constraints as an explanation for the dynamic behaviour of aggregate investment and cabral and mata 1996 are able to fit reasonably well the size distribution of portuguese manufacturing firms by estimating a simple model of financing constraints for surveys see hubbard 1998 and stein 2003

evidence on the role of cash flow for investment abstract recent work in macroeconomics argues that imperfections in capital markets may lead to business cycle fluctuations by propagating relatively modest shocks evidence for such a mechanism also known as the financial accelerator consists largely of firm level studies showing that cash flow is an important predictor of investment but this evidence is often viewed with skepticism because cash flow is also a good indicator of investment opportunities in this paper we develop a framework for estimating the extent to which the predictive power of cash flow can be attributed to its role as a fundamental versus its role in alleviating credit frictions for firms with access to commercial paper and bond markets we find that the perfect capital markets model of investment can fully account for the role of cash flow for firms with only limited access to capital markets as indicated by lack of participation in public debt markets however investment appears to be excessively sensitive to fluctuations in cash flow these results thus clarify the role of cash flow in investment equations and provide support for the existence of a financial accelerator

the kuznets process and the inequality development relationship abstract in his classic paper on economic growth and income inequality kuznets discussed the process of population shift from traditional to modern activities as the basis for a theory of distributional change during the course of development in this paper we present a formalization of the kuznets process conduct a general analysis of distributional change under this process and derive the functional forms of and conditions for a turning point in the inequality development relationship for six commonly used indices of inequality the functional form appropriate to each index is then estimated using cross section data on 60 developing and developed countries finally some extensions to the initial formalization of the kuznets process are considered

regional economic impacts of biomass based energy service use a comparison across crops and technologies for east styria austria abstract biomass action plans in many european countries seek to expand biomass heat and fuel supply mainly to be supplied by peripheral agricultural regions we develop a two plus ten region energy focused computable general equilibrium cge model that acknowledges land competition in analysing the sub state local regional economic implications of such a strategy embedded within a global context our model is based on a full cost analysis of selected biomass technologies covering a range of agricultural and forestry crops as well as thermal insulation the local regional macroeconomic effects differ significantly across technologies and are governed by factors such as net labour intensity in crop production the high land intensity of agricultural biomass products crowds out conventional agriculture and thus lowers employment and drives up land prices and the consumer price index the regional economic results show that net employment effects are positive for all forestry based biomass energy and also show for which agriculture based biomass systems this is true even when accounting for land competition when regional consumer price development governs regional wages or when the agricultural sector is in strong enough competition to the international market positive employment and welfare impacts vanish fully for agriculture based bio energy

sticky prices and costly credit we develop a theory of money and credit as competing payment instruments then put it to work in applications agents use cash and credit because the former latter is subject to the inflation tax transaction costs frictions that make the choice of payment method interesting also imply equilibrium price dispersion we derive closed form solutions for money demand and show how to simultaneously account for the price change facts cash credit shares in micro data and money interest correlations in macro data the effects of inflation on welfare price dispersion and markups are discussed as are nonstationary equilibria with dynamics in the price distribution

is income inequality persistent evidence using panel stationarity tests 1870 2011 using data on inequality for 21 oecd countries over the period 1870 2011 this paper tests the piketty hypothesis that income inequality is likely to grow in the 21st century it is shown that the null hypothesis of trend stationarity of inequality cannot be rejected at conventional significance levels suggesting that shocks to income inequality are likely to be temporary

the risk free rate in heterogeneous agent incomplete insurance economies abstract why has the average real risk free interest rate been less than one percent the question is motivated by the failure of a class of calibrated representative agent economies to explain the average return to equity and risk free debt i construct an economy where agents experience uninsurable idiosyncratic endowment shocks and smooth consumption by holding a risk free asset i calibrate the economy and characterize equilibria computationally with a borrowing constraint of one year s income the resulting risk free rate is more than one percent below the rate in the comparable representative agent economy

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

welfare costs of inflation in a menu cost model recent years have seen substantial prog ress in our understanding of pricing decisions at the micro level access to large scale data sources on prices of individual products has given us rich information on how frequently prices change by what magnitude and how the aggregation of price changes in individual firms maps into aggregate inflation see among many others mark bils and peter j klenow 2005 these facts about price movements are a key input in recent quantitative models of the aggre gate effects of nominal rigidities e g mikhail golosov and robert e lucas 2007 in this paper we use both the new facts and the new quantitative models to revisit an old question namely that of quantifying the welfare benefits of low inflation our model includes two

financing of firms labor reallocation and the distributional role of monetary policy we analyze monetary policy in a heterogenous firms environment where cash con strained firms finance operations through external financing and cash unconstrained firms operate by using internal funds we show that firms respond differently to shocks expansionary monetary policy sharply increases the relative employment of the cash constrained firms while positive productivity shocks induce a rise in the relative employment of the cash unconstrained firms our analysis points to a clear role of monetary policy in reallocating resources across sectors that differ in their financing capabilities furthermore the predictions of our model match the empirical evidence implying that financially constrained firms react sharply to monetary policy shocks but are less cyclical than unconstrained firms following productivity shocks

capital and wealth in the twenty first century abstract in capital in the twenty first century thomas piketty uses the market value of tradable assets to measure both productive capital and wealth as a measure of wealth this is problematic because it ignores the value of human capital and transfer wealth which have grown enormously over the last 300 years thus the constancy of the wealth income ratio as portrayed in his data is an illusion further the types of wealth that he does not measure are more equally distributed than tradable assets the approach also incorrectly identifies capital gains due to reduced discount rates as increases in the capital stock
