occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

economics of a bottleneck abstract drawing on vickrey amer econ rev 59 251 261 1969 and subsequent literature this paper provides a thorough economic analysis of the simplest bottleneck model of road congestion with peak load demand in the morning rush hour a fixed number of identical individuals one per car must travel from home to work between which is a bottleneck of given capacity the costs of travel include queuing time and schedule delay time early or late for work the frequency distribution of departure times adjusts so that in equilibrium all individuals have the same travel costs the paper extends the previous literature by examining a coarse toll and solving for optimal capacities the application of congestion tolls can generate efficiency gains by altering the frequency distribution of departure times previous estimates of the efficiency gains from congestion tolling are likely to be substantially downward biased because they have ignored this effect

the ramsey problem for congestible facilities abstract in recent years a new set of models drawing on vickrey 1969 has been developed to analyze the economics of congestible facilities these models are structural in that they derive the cost function from consumers time of use decisions and the congestion technology standard models in contrast simply assume the general form of the cost function we apply the new approach to analyze the ramsey problem for a congestible facility and show that the solution generally entails cost inefficiency standard models have failed to reveal this result because they treat the cost function as completely determined by technology

uniform versus peak load pricing of a bottleneck with elastic demand abstract this paper considers commuting to work across a bottleneck such as a bridge or tunnel with elastic demand with no toll there is wasteful queueing the optimal peak load toll eliminates queueing and leaves total traffic unchanged the second best uniform toll cannot eliminate queueing but reduces total traffic the second best uniform toll may be larger or smaller than the maximum value of the optimal peak load toll

capture and ideology in the economic theory of politics the economic theory of regulation long ago put public interest theories of politics to rest these theories have correctly been viewed as normative wishings rather than explanations of real world phenomena they have been replaced by models of political behavior that are consistent with the rest of microeconomics anthony downs 1957 james buchanan and gordon tullock 1965 george stigler 1971 sam peltzman 1976 recently however debate has arisen over whether some version of a public interest theory of regulation will have to be readmitted to our thinking about actions and results in the political arena what is at issue is the empirical importance of the altruistic publicly interested goals of rational actors in determining legislative and regulatory outcomes james kau and paul rubin 1979 kalt 1981 peltzman 1982 this study assesses the nature and significance of publicly interested objectives in a particular instance of economic policymaking u s senate voting on coal strip mining regulations the existence of such objectives is of course no contradiction of the economic view of human behavior kenneth arrow 1972 gary becker 1974 and may well be rooted in genetic biological history becker 1976 jack hirshleifer 1978 generally however individuals altruistic publicly interested goals have been given little attention this reflects the judgment that such goals are so empirically unimportant as to allow the use of occam s razor in positive models or well founded apprehensions that these goals are unusually difficult to identify measure and analyze notwithstanding the latter problem we find that approaches which confine themselves to a view of political actors as narrowly egocentric maximizers explain and predict legislative outcomes poorly the tracking and dissecting of the determinants of voting on coal strip mining policy suggest that the economic theory of politics has been prematurely closed to a broader conception of political behavior

testing for liquidity constraints in euler equations with complementary data sources previous tests for liquidity constraints using consumption euler equations have frequently split the sample on the basis of wealth arguing that low wealth consumers are more likely to be constrained we propose alternative tests using different and more direct information on borrowing constraints obtained from the 1983 survey of consumer finances in a first stage we estimate probabilities of being constrained which are then utilized in a second sample the panel study of income dynamics to estimate switching regression models of the euler equation our estimates indicate stronger excess sensitivity associated with the possibility of liquidity constraints than the sample splitting approach

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

persistent media bias abstract the news media plays an essential role in society but surveys indicate that the public views the media as biased this paper presents a theory of media bias that originates with private information obtained by journalists through their investigations and persists despite profit maximizing news organizations and rivalry from other news organizations bias has two effects on the demand for news first rational individuals are more skeptical of potentially biased news and thus rely less on it in their decision making this skepticism reduces demand and leads the news organization to set a lower price for its publication the greater is the bias it tolerates lower quality news thus commands a lower price second bias makes certain stories more likely than others given their private information journalists may bias their stories if their career prospects can be advanced by being published on the front page news organizations can control bias by restricting the discretion allowed to journalists but granting discretion and tolerating bias can increase profits if it allows journalists to be hired at a lower wage bias is not driven from the market by a rival news organization nor by a news organization with an opposing bias and the profits of a high bias news organization can be higher than the profits of a low bias one moreover bias can be greater with competition than with a monopoly news organization if individuals collectively choose regulation in place of their individual decision making bias increases the expected stringency of regulation

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

income inequality financial development and macroeconomic fluctuations we examine the relationship between income inequality and variability in aggregate consumption growth in high income countries greater income inequality appears to be associated with more volatility in consumption growth whereas in lower income countries higher levels of income inequality tend to be associated with less volatility we present evidence that variability in real gdp growth is also related to income inequality in the same way our results suggest that the level of financial development may help to explain why the distribution of income affects the short run variability of consumption and output differently in high income countries than in low income countries

empirical determinants of corruption a sensitivity analysis many variables have been proposed by past studies as significant determinants of corruption this paper asks if their estimated impact on corruption is robust to alteration of the information set a global sensitivity analysis based on the leamer s extreme bounds analysis gives a clear answer five variables are robustly related to corruption corruption is lower in richer countries where democratic institutions have been preserved for a long continuous period and the population is mainly protestant corruption is instead higher where political instability is a major problem finally a country s colonial heritage appears to be a significant determinant of present corruption

who is credit constrained in the u s economy an important assumption of the life cycle model of consumption is the postulate of perfect capital markets this hypothesis has recently been challenged by substantial empirical evidence hall and mishkin 1982 using the panel study of income dynamics estimate that 20 percent of united states families are liquidity constrained mariger 1986 derives a life cycle model with endogenous liquidity constraints and using a cross section estimates this fraction to be 19 4 percent hubbard and judd 1986 simulate a model with a constraint on net worth which shows that with reasonable assumptions about preferences 19 0 percent of united states consumers are liquidity constrained the emerging consensus points therefore to a fraction of approximately 20 percent of the population behaving in a manner that is inconsistent with the pure life cycle model in addition hayashi 1985 and zeldes 1989 investigate the correlation among consumption wealth and income for various population groups and infer that liquidity constraints are more important for younger families with low levels of wealth and saving the main limitation of these studies is that in their data sets constrained consumers are not observable and have to be identified via indirect evidence thus there is as yet little firm evidence about the characteristics of the consumers who are likely to be credit constrained this paper adopts an approach that differs from previous tests for liquidity constraints because it makes use of data where constrained consumers are observable and explicitly links their existence to credit market imperfections and personal characteristics the data drawn from the 1983 survey of consumer finances scf and described in section ii provide information on individuals whose request for credit has been rejected by financial intermediaries in section iii a model is developed in which consumers and lenders behavior jointly determines the probability that a consumer is rationed in the credit market this probability is then

circulation versus advertiser appeal in the newspaper industry an empirical investigation advertising space is not a homogeneous commodity but something whose value depends on the characteristics of a newspaper s readership it is suggested in particular that the proportion of readers belonging to the more affluent social categories will exert a strong positive influence on advertising this paper investigates the circulation readership profile relation using a simple simultaneous equation framework the model is then estimated across a sample of british and irish daily and sunday newspapers using data collected from industry sources the paper then seeks to quantify the trade off between circulation and the proportion of high income readers copyright 1989 by blackwell publishing ltd

radio s impact on public spending if informed voters receive favorable policies then the invention of a new mass medium may affect government policies since it affects who is informed and who is not these ideas are developed in a voting model the model forms the basis for an empirical investigation of a major new deal relief program implemented in the middle of the expansion period of radio the main empirical finding is that u s counties with many radio listeners received more relief funds more funds were allocated to poor counties with high unemployment but controlling for these and other variables the effects of radio are large and highly significant

clubs local public goods and transportation models a synthesis abstract clubs local public goods and transportation models are analyzed within a unified model the emphasis is on the derivation of optimal allocation pricing and the size of the sharing group we derive the conditions under which optimal prices will yield surplus or deficit as well as those under which competitive provision will be efficient given heterogeneous tastes we prove that segregation according to tastes is generally efficient although several cases where this result does not hold are also discussed we show that the existing literature is unnecessarily restrictive and that the unified approach suggested here considerably extends the existing analysis of clubs local public goods and the transportation problems

a new data set measuring income inequality this article presents a new data set on inequality in the distribution of income the authors explain the criteria they applied in selecting data on gini coefficients and on individual quintile groups income shares comparison of the new data set with existing compilations reveals that the data assembled here represent an improvement in quality and a significant expansion in coverage although differences in the definition of the underlying data might still affect inter temporal and international comparability based on this new data set the authors do not find a systematic link between growth and changes in aggregate inequality they do find a strong positive relationship between growth and reduction of poverty

spillovers stratification and inequality this paper surveys some recent work which seeks to model persistent income inequality and explain such phenomena as ghetto formation and poverty traps the paper illustrates how a number of these models possess a common structure in which local spillover effects interact with income based stratification of neighborhoods to transmit parental economic status from generation to generation as such these models represent an extension of the macroeconomic literature on spillovers and coordination failures to economic environments which endogenize the interaction environments of individual agents the theoretical and empirical justifications of these spillover and stratification effects are discussed finally some empirical implications of these models are analyzed

the political economy of government responsiveness theory and evidence from india the determinants of government responsiveness to its citizens is a key issue in political economy here we develop a model based on the solution of political agency problems having a more informed an politically active electorate strengthens incentives for governments to be responsive this suggests that there is a role both for democratic institutions and the mass media in ensuring that the preferences of citizens are reflected in policy the ideas behind the model are tested on panel data from india we show that public food distribution and calamity relief expenditure are greater controlling for shocks where governments face greater electoral accountability and where newspaper circulation is highest

queues rations and market comparisons of outcomes for the poor and the rich this paper presents a positive comparison of the outcomes of several alternative allocation systems the queue system convertible and nonconvertible rations and the unhindered market to distribute the limited quantity of a deficit good among heterogeneous individuals the authors show that for the poor the ranking of systems from better to worse is convertible rations nonconvertible rations the queue system and nonintervention the rich are found to be better off under nonintervention than under other systems these and other results are notably robust not only to many parameters of the economy but also to certain types of commodity taxes and administrative costs copyright 1987 by american economic association

government control of the media abstract we present a formal model of government control of the media to illuminate variation in media freedom across countries and over time media bias is greater and state ownership of the media more likely when the government has a particular interest in mobilizing citizens to take actions that further some political objective but are not necessarily in citizens individual best interest however the distinction between state and private media is smaller large advertising markets reduce media bias in both state and private media but increase the incentive for the government to nationalize private media media bias in state and private media markets diverge as governments become more democratic whereas media bias in democracies and autocracies converge as positive externalities from mobilization increase

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

serial correlation and the fixed effects model this paper generalizes the durbin watson type statistics to test the ols residuals from the fixed effects model for serial independence also generalized are the tests proposed by sargan and bhargava for the hypothesis that the residuals form a random walk a method for efficient estimation of the parameters is also developed finally an earnings function is estimated using the michigan survey of income dynamics in order to illustrate the uses of the tests and the estimation procedures developed in this paper

externalities in economies with imperfect information and incomplete markets this paper presents a simple general framework for analyzing externalities in economies with incomplete markets and imperfect infonnation by identifying the pecuniary effects of these externalities that net out the paper simplifies the problem of determining when tax interventions are pareto improving the approach indicates that such tax interventions almost always exist and that equilibria in situations of imperfect information are rarely constrained pareto optima it can also lead to simple tests based on readily observable indicators of the efficacy of particular tax policies in situations involving adverse selection signaling moral hazard incomplete contingent claims markets and queue rationing equilibria traditional discussions of externalities have emphasized the distinction between technological externalities in which the action of one individual or firm directly affects the utility or profit ofanother and pecuniary externalities in which one individual s or firm s actions affect another only through effects on prices while the presence of technological externalities imply in general that a competitive equilibrium may not be pareto efficient pecuniary externalities hy themselves are not a source of inefficiency the fact that prices change has of course important consequences there are both distributional and allocational effects but the distribution effects net out gains for example hy firms whose prices increase are precisely offset by losses e g to individuals who must pay higher prices and there are no welfare losses from the allocation effects as long as the price changes involved are small if firms are maximizing profits and individuals are maximizing utility both facing prices that correctly refiect opportunity costs then standard envelope theorem arguments imply that changes in profits or utility induced by changes in allocations resulting from any small change in prices are negligible

is the media liberal an indirect test using news magazine circulation many critics allege that the us national news media is biased in favour of liberal causes and democratic candidates the lack of an objective measure of news content ensures that such charges remain controversial i consider an indirect test for media bias if the national news media do exhibit a liberal bias consumption should be higher in liberal media markets ceteris paribus i examine determinants of circulation of the three major weekly news magazines across the us and find that newsweek and time have higher circulation in liberal markets while us news has higher circulation in conservative markets the evidence is consistent with a liberal bias for time and newsweek while us news may be relatively conservative but still left of centre or absolutely conservative

media bias in china this paper examines whether and how market competition affected the political bias of government owned newspapers in china from 1981 to 2011 we measure media bias based on coverage of government mouthpiece content propaganda relative to commercial content we first find that a reform that forced newspaper exits reduced competition affected media bias by increasing product specialization with some papers focusing on propaganda and others on commercial content second lower level governments produce less biased content and launch commercial newspapers earlier eroding higher level governments political goals third bottom up competition intensifies the politico economic tradeoff leading to product proliferation and less audience exposure to propaganda

the influence of governance infrastructure and corporate governance on profit shifting in this article we develop a conceptual model to examine the influence of quality of country level governance infrastructure and corporate governance effectiveness on profit shifting we empirically test propositions derived from the model with a unique firm level data set and using multiple indicators of governance infrastructure quality and corporate governance mechanisms we estimate that on average about 6 of total pre tax income is shifted out of foreign owned firms in india we show that governance infrastructure that improves collective action and transparency in both the foreign and host country reduces shifting on the other hand secure property rights and efficient contracting in the foreign country increases shifting we also find that monitoring by foreign institutional investors restricts shifting

when can a news organization lead public opinion ideology versus market forces in decisions to make news do news organizations purposefullylead the public to support a particularideological agenda when debating thisquestion many analysts draw conclusionsfrom weak empirical evidence we introducea model that clarifies how a newsorganization s internal structure combineswith market forces to affect when it canlead public opinion we identify conditionsunder which liberal reporters orpolitically driven media magnates canachieve ideological goals we alsoilluminate important barriers that preventmany would be public opinion leaders fromever satisfying these conditions we showthat internal structure and market forcesare critical determinants of any newsorganization s power over public opinion

the market for news we investigate the market for news under two assumptions that readers hold beliefs which they like to see confirmed and that newspapers can slant stories toward these beliefs we show that on the topics where readers share common beliefs one should not expect accuracy even from competitive media competition results in lower prices but common slanting toward reader biases on topics where reader beliefs diverge such as politically divisive issues however newspapers segment the market and slant toward extreme positions yet in the aggregate a reader with access to all news sources could get an unbiased perspective generally speaking reader heterogeneity is more important for accuracy in media than competition per se

financial development unemployment volatility and sectoral dynamics abstract we document a negative and significant relationship between domestic financial development and unemployment volatility in developing and emerging economies demes and the absence of such relationship in advanced economies aes a business cycle labor search model with firm heterogeneity collateral constraints and interfirm input credit capital can quantitatively rationalize these facts greater financial development is associated with lower usage of input credit capital greater bank credit and greater capital accumulation all of which make firms more resilient in the presence of financial shocks firms increased shock resiliency stabilizes employment decisions ultimately leading to smoother unemployment fluctuations then by establishing explicit linkages between firms interfirm input credit acts as an important mechanism that fosters lower volatility across firms under greater financial development as such increases in financial development have a smaller impact in stabilizing unemployment in economies with higher average bank credit gdp ratios and less input credit usage which is the case of aes compared to economies with lower average bank credit gdp ratios and more input credit usage which is the case of demes

the craft of labormetrics using a wide array of examples from the literature and from original estimates the author examines the pitfalls that make good empirical research in labor economics at least as much craft as statistical technique among the subjects discussed are the appropriateness and cleanliness of data problems of extreme observations the validity of attempts to produce exogeneity using instrumental variables natural experiments and structural models and the treatment of selectivity and unobservable individual effects the author stresses the importance of testing empirical results to ensure that they make sense and of presenting them clearly and economically

local versus non local effects of chinese media and post earnings announcement drift abstract taking advantage of the institutional difference in capture between local and non local media in china we examined the association between media capture and post earnings announcement drift pead using both portfolio and regression analyses we found that for the same firms non local media coverage is negatively associated with pead however there is no association between local media coverage and pead except for non state owned firms given that in china non local media are less captured or more independent than local media the negative association observed for non local media coverage can be interpreted as an indication that media independence plays a role in reducing pead or improving informational efficiency in the stock market

who owns the media the authors examine patterns of media ownership in 97 countries around the world they find that almost universally the largest media firms are controlled by the government or by private families government ownership is more pervasive in broadcasting than in the printed media government ownership is generally associated with less press freedom fewer political and economic rights inferior governance and most conspicuously inferior social outcomes in education and health the adverse effects of government ownership on political and economic freedom are stronger for newspapers than for television the adverse effects of government ownership of the media do not appear to be restricted solely to instances of government monopoly the authors present a range of evidence on the adverse consequences of state ownership of the media state ownership of the media is often argued to be justified on behalf of the social needs of the disadvantaged but if their findings are correct increasing private ownership of the media through privatization or by encouraging the entry of privately owned media can advance a variety of political and economic goals especially those of meeting the social needs of the poor

the liberal media bias or customer preferences allegations of liberal bias against the national news media in the us remain very contentious conservative critics of the media argue biased news stems from liberal leaning journalists another explanation of alleged bias could be that liberals have a greater demand for news than moderates or conservatives so the media simply tailors its product to their customers i test whether liberals in the us have a greater demand for news by investigating the determinants of newspaper circulation across states and metropolitan areas i find mixed evidence for liberal demand circulation is higher in more liberal metropolitan areas but is independent of local political preferences across states

heterogeneity stratification and growth macroeconomic implications of community structure and school finance this paper examines how socioeconomic stratification and alternative systems of education finance affect inequality and growth agents interact through local public goods or externalities school funding neighborhood effects and economywide linkages complementary skills knowledge spillovers sorting families into homogeneous communities often minimizes the costs of existing heterogeneity but mixing reduces heterogeneity faster integration therefore tends to slow down growth in the short run yet raise it in the long run a move to state funding of education presents society with a similar intertemporal trade off local and global complementarities play major roles in determining the efficient social and educational structures copyright 1996 by american economic association

sunshine as disinfectant the effect of state freedom of information act laws on public corruption abstract we assess the effect of freedom of information act foia laws on public corruption in the united states specifically we investigate the impact of switching from a weak to a strong state level foia law on corruption convictions of state and local government officials the evidence suggests that strengthening foia laws has two offsetting effects reducing corruption and increasing the probability that corrupt acts are detected the conflation of these two effects led prior work to find little impact of foia on corruption we find that conviction rates approximately double after the switch which suggests an increase in detection probabilities however conviction rates decline from this new elevated level as the time since the switch from weak to strong foia increases this decline is consistent with officials reducing the rate at which they commit corrupt acts by about 20 these changes are more pronounced in states with more intense media coverage for those that had more substantial changes in their foia laws for foia laws which include strong liabilities for officials who contravene them for local officials and for more serious crimes conviction rates of federal officials who are not subject to the policy show no concomitant change

self selection and pareto efficient taxation abstract this paper analyses the set of pareto efficient tax structures the formulation of the problem as one of self selection not only shows more clearly the similarity between this problem and a number of other problems such as the optimal pricing of a monopolist which have recently been the subject of extensive research but also allows the derivation of a number of new results we establish i under fairly weak conditions randomization of tax structures is desirable ii if different individuals are not perfect substitutes for one another in production then the general equilibrium effects until now largely ignored in the literature of changes in the tax structure may be dominant in determining the optimal tax structure in particular if the relative wage of high ability and low ability individuals depends on the relative supplies of labor the optimal tax structure entails a negative marginal tax rate on the high ability individuals and a positive marginal tax rate on the low ability individuals the marnitude of which depends on the elasticity of substitution iii if individuals differ in their preferences pareto efficient taxation may entail negative marginal tax rates for high incomes while iv if wage income is stochastic the marginal tax rate at the upper end may be 100 our analysis thus makes clear that the main qualitative properties of the optimal tax structure to which earlier studies called attention are not robust to these attempts to make the theory more realistic
