unemployment and effort at work we measure the sensitivity of work effort to local labour market conditions using self reported non work at the workplace in the american time use survey atus 2003 12 non work at work is quantitatively significant and varies positively with local unemployment but in opposite directions at the extensive and intensive margins the fraction of workers reporting positive values declines with unemployment while time spent in non work conditional on any such time rises with unemployment the results speak to issues of labour hoarding efficiency wages and the cyclicality of labour productivity we also demonstrate a relationship between the incidence of non work and unemployment benefits in state data linked to the atus there are also pronounced occupational differences in the incidence and intensity of non work

welfare improving adverse selection in credit markets a model of simultaneous adverse selection and moral hazard in a competitive credit market is developed and used to show that aggregate borrower welfare may be higher in the combined case than in the moral hazard only case adverse selection can be welfare improving because in the pooling equilibrium of the combined model high quality borrowers cross subsidize low quality borrowers the cross subsidization reduces the overall moral hazard effort effects and the resulting gain in welfare may more than offset the welfare loss stemming from distorted investment choices the analysis focuses on pooling equilibria because model structure precludes separating equilibria

the role of interest rate taxes in credit markets with divisible projects and asymmetric information this paper assumes that entrepreneurs have divisible projects with random payoffs however managerial skill is unobservable to outsiders projects are assumed to be financed through debt a pooling equilibrium is shown to exist in which good and bad entrepreneurs sell debt at the same price if both types of entrepreneur have a positive probability of bankruptcy project scale will be too large this provides a prima facie case for raising interest rates and hence the cost of capital through taxation if in equilibrium only the poor entrepreneurs go bankrupt there is an outlying possibility that interest rates are too low and a subsidy is called for

business borrowing and control a theory of entrepreneurial types a formal model of the bank borrowing decision by the small firm is provided to explain why some entrepreneurs borrow and others do not and why some businesses grow and others remain stationary over long periods loan capital is productive and increases the firm s revenue but brings the business under the control of the bank profits generated by borrowing are a good increasing owner utility whereas control is a bad reducing it the consequent tradeoff between borrowing and control implies that the business optimum will involve borrowing less than the amount that maximises profits if owner control aversion is strong enough equilibrium may involve a corner solution with the business being entirely self funding the above result holds under conditions of symmetric information and zero credit rationing dynamic analysis distinguishes one group of entrepreneurs movers whose preferences towards control evolve through time and their control aversion diminishes from another group stayers whose preferences remain stationary for the movers borrowing increases over time up to a profit maximising optimum whereas for the stayers independence of control is maintained but at the expense of non growth

imperfect information and the theory of government intervention in farm credit markets this paper describes some possible economic motivations for government intervention in farm credit markets these motivations are made possible by explicit departures from the perfect information and complete market assumptions that underlie both the neoclassical competitive paradigm and the fundamental theorems of welfare economics to be more precise the analysis focuses on three types of asymmetric information between farmers and prospective outside investors both of whom are assumed to be risk neutral arguably the three informational asymmetries examined here represent natural departures from perfect markets in that unlike the unencumbered neoclassical model each elicits farmers optimal use of debt contracts rather than equity instruments or other contractual forms to raise investment capital despite their consistency with observed contractual choices all three of the models analyzed below yield free market equilibria that diverge from first best perfect information outcomes given the inefficiency of these market equilibria the key question raised and discussed here is can government improve upon the derived competitive outcomes and if so how despite the enormity of the credit rationing literature only a few extant studies address this question in models that are consistent with debt contracts among them are demeza and webb 1987 1988 1989 and innes 1988 which focus on the third type of informational asymmetry considered below the other two information structures posited in this paper have been studied in several analyses of credit markets but with attention focused on positive attributes of the unfettered competitive equilibrium rather than on prospective implications for welfare enhancing government intervention in what follows th s literature is surveyed and for the first two information structures some new policy results a e presented a critical discussion of the paper s limitations concludes the article

data watch the american time use survey we discuss the new american time use survey atus an on going household survey of roughly 1 200 americans per month 1 800 per month in the first year 2003 that collects time diaries as well as demographic interview information from respondents who had recently been in the current population survey the characteristics of the data are presented as are caveats and concerns that one might have about them a number of novel uses of the atus in economic research including in the areas of macroeconomics national income accounting labor economics and others are proposed to illustrate the magnitude of this new survey s possible applications

the nonprofit sector and industry performance abstract despite the importance of nonprofit industries in the economy little analysis has been conducted as to whether the behavior of such industries differs from that of for profit industries extending previous firm level analyses we propose a neoclassical theory with an endogenous nonprofit sector our analysis implies that nonprofit firms have a competitive advantage over for profit firms so that marginal changes in the industry operate through the for profit sector as such marginal industry behavior is identical to that of a for profit industry and nonprofit regulations may have a limited impact or even no impact on overall industry performance our theory has the methodological advantage that standard for profit analysis applies directly to nonprofit firms because they can be analyzed as for profit firms with lower costs we discuss aspects of the empirical literature that test this theory of nonprofit activity

why do governments use closed ended subsidies to support entrepreneurial investment abstract public assistance programs for entrepreneurial investment often consist of closed ended subsidies this paper shows that this instrument may be superior to open ended subsidies if capital markets are characterized by problems of asymmetric information

learning by doing and learning from others human capital and technical change in agriculture household level panel data from a nationally representative sample of rural indian households describing the adoption and profitability of high yielding seed varieties hyvs associated with the green revolution are used to test the implications of a model incorporating learning by doing and learning spillovers the estimates indicate that i imperfect knowledge about the management of the new seeds was a significant barrier to adoption ii this barrier diminished as farmer experience with the new technologies increased iii own experience and neighbors experience with hyvs significantly increased hyv profitability and iv farmers do not fully incorporate the village returns to learning in making adoption decisions

impacts of subsidized hybrid seed on indicators of economic well being among smallholder maize growers in zambia we test the hypotheses that subsidies on hybrid seed change maize production total household income the severity of poverty and relative deprivation among smallholder maize growers in zambia the analysis contributes to the literature by measuring the quantitative effects of seed as compared to fertilizer subsidies on indicators of household well being rather than input demand we apply a combination of econometric approaches to a nationally representative balanced panel of smallholder maize growing households and invoke the chain rule to generate quantitative estimates of impacts per kilogram of subsidized seed our findings demonstrate that in the initial years of the program subsidized seed enhanced the well being of smallholder maize growers according to each indicator but by small magnitudes simple calculations suggest high private and social benefit cost ratios when benefits are measured in terms of household income although magnitudes are sensitive to seed price and administrative costs

credit market efficiency and tax policy in the presence of screening costs after establishing the existence of capital market equilibrium in the presence of asymmetric information and screening costs this paper examines tax policies designed to correct the attendant externalities when projects differ in expected returns it is shown to be ambiguous whether costly private screening weakens or strengthens the case for an interest income tax however when projects differ only in riskiness as in the model of stiglitz and weiss screening opportunities cause the efficiency case for tax intervention to disappear

markets and pro poor agricultural growth insights from livelihood and informal rural economy models in malawi this article presents the development of a set of programming models describing the major features of different rural livelihoods and of the informal rural economy they together make up in malawi the models allow for differentiated responses by different household types to change and for the partial equilibrium effects of consequent supply demand and price adjustments in labor and grain markets the models provide insights into the relations between own farm and nonown farm activities in different households livelihoods and in the informal rural economy as a whole and are used to investigate possible impacts of increasing cash crop prices and of a more open rural economy impacts of these changes on the poor are found to be critically dependent upon supply and demand elasticities in labor and grain markets but the poor could potentially suffer significant losses from increased openness of the local economy leading to increased expenditure by less poor households on imported goods and services

cyclical variation in labor hours and productivity using the atus we examine monthly variation in weekly work hours using data for 2003 10 from the current population survey cps on hours worker from the current employment survey ces on hours job and from the american time use survey atus on both the atus data minimize recall difficulties and constrain hours of work to accord with total available time the atus hours worker are less cyclical than the cps series but the hours job are more cyclical than the ces series we present alternative estimates of productivity based on atus data and find that it is more pro cyclical than other productivity measures

zambia s input subsidy programs over the last decade subsidies for fertilizer and hybrid maize seed have re emerged as a cornerstone of the government of the republic of zambia s grz s agricultural development and poverty reduction strategies this article reviews the farmer input support programme fisp and other grz input subsidy programs since structural adjustment it then synthesizes existing and presents new empirical evidence on the programs targeting outcomes and effects results suggest that although 73 of smallholder households cultivate less than 2 hectares of land and that these households constitute 78 of the smallholder farms below the us 1 25 capita day poverty line the majority 55 of fisp fertilizer goes to households that cultivate larger areas other factors constant wealthier households receive more subsidized inputs subsidized fertilizer promotes maize intensification and extensification at the expense of fallow land but an additional kg of subsidized fertilizer only raises maize output by 1 88 kg on average as a result of low maize fertilizer response rates poor targeting crowding out and diversion of fertilizer intended for the program financial benefit cost ratios for fisp fertilizer are well below one the article concludes with recommended reforms to fisp including that it be downsized and the savings invested in known drivers of pro poor agricultural growth

too much investment a problem of asymmetric information this paper shows that under plausible assumptions the inability of lenders to discover all of the relevant characteristics of borrowers results in investment in excess of the socially efficient level raising the rate of interest above the free market level will restore optimality this conflicts with generally held views and is contrasted with the stiglitz weiss model it is shown that the assumptions which yield overinvestment support debt as the equilibrium method of finance however under the stiglitz weiss assumptions used to derive an underinvestment result equity is shown to be the equilibrium method of finance

disrupting demand for commercial seed input subsidies in malawi and zambia summary this study uses nationally representative household level panel data from malawi and zambia to identify the determinants of subsidized maize seed and fertilizer receipt and to estimate how input subsidies affect households commercial purchases of improved maize seed varieties in both countries we find that households in areas where the ruling party won the last presidential election acquire significantly more subsidized inputs than other households results also indicate that each additional kilogram of subsidized maize seed acquired by a household reduces its commercial improved maize seed purchases by 0 58 kg in malawi and by 0 49 kg in zambia on average

the effect of household wealth on the adoption of improved maize varieties in zambia abstract production and price risks that could render input use unprofitable sometimes prevent rural households from benefiting from input technological change the household s ability to cope with such risks and hence benefit from input technological change is often positively related to its wealth or stock of productive assets empirical evidence however suggests a non linear relationship between wealth and adoption of new agricultural technologies so that within a rural community households on the lower wealth continuum behave differently from those on the higher level using farm level data collected from 300 randomly selected households in three districts of zambia in 2004 2005 crop season this paper first stratifies households into poorly and well endowed households based on their access to productive assets and estimates separate double hurdle models for the adoption of improved high yielding maize ihym varieties for each group the results show that factors influencing the adoption and use intensity of ihym varieties differ between the two groups this draws attention to the need for recommending wealth group specific interventions to increase the adoption and use intensity of such varieties and their subsequent impacts on food security and general livelihoods of the households the explicit testing for the possibility that differences in household wealth affect the way in which other variables influence adoption decisions is the paper s unique contribution to the adoption literature

adverse selection investment and profit taxation abstract this article introduces government revenue requirements and attendant taxation into a financial market model with informed borrowers entrepreneurs and uninformed lenders it finds that 1 in general an allocationally neutral proportional profit tax yields an equilibrium which is constrained inefficient despite the constrained efficiency of the no tax equilibrium 2 many constrained efficient allocations can only be supported by a profit tax regime which depends on the entrepreneur s investment choice and thus which is tantamount to direct intervention in the financial market and 3 some first best allocations can be supported by an investment invariant tax regime which includes a proportional profit tax and a positive fixed transfer

signaling in credit markets in this paper we show that under a variety of alternative assumptions about the private information of loan applicants a competitive market for loans is characterized by screening banks separate out loan risks by offering higher loans at higher interest rates depending on the nature of the informational asymmetry it may be that applicants with less risky projects select larger rather than smaller loans comparative statics implications are also examined in particular we explore the effects of an increase in banks cost of funds on average loan quality

investment and government intervention in credit markets when there is asymmetric information abstract this paper models private firm investment choices and government credit policy in an entrepreneurial firm financial market wherein firm owners have better information about the quality of their return distributions than do external financiers the analysis shows that despite the absence of an informational advantage the government can often increase social welfare by offering subsidized debt contracts however the paper also finds that some common credit subsidy policies including loan guarantees and government backing of targeted lending institutions yield constrained inefficient outcomes in general

do input subsidy programs crowd in or crowd out commercial market development modeling fertilizer demand in a two channel marketing system many governments in developing countries distribute fertilizer at subsidized prices in an effort to stimulate small farmers agricultural productivity and food security prior fertilizer demand studies have largely failed to account for the effects of government programs on farmers commercial purchases using a double hurdle model and nationally representative rural household panel data in zambia we distinguish between these sources and measure the contemporaneous crowding in and crowding out effects of government input programs on commercial fertilizer sales where the private sector is relatively active and average wealth is higher areas seemingly more likely to be targeted by government programs results indicate that subsidies have substantially crowded out the private sector in some cases to the point that such programs could actually lower overall fertilizer use on the other hand in poorer areas where the private sector is relatively inactive subsidies help to generate demand and crowd in private sector retailers empirical studies explicitly modeling farmers fertilizer purchase behavior within a dual marketing framework can provide important insights for agricultural policy discussions in developing countries

are business startups debt rationed using a large random sample of u k start ups and a rich data set the paper demonstrates that human capital is the true determinant of survival and that the correlation between financial capital and survival is spurious provision of finance is demand driven with banks supplying funds elastically and business requests governing take up firms self select for funds on the basis of the human capital endowments of the proprietors with better businesses more likely to borrow a reason why others have seemingly identified start up debt gaps may be the failure to test a sufficiently rich empirical model copyright 1996 by royal economic society

unemployment market work and household production time diary data from four countries suggest that differences in market time between the unemployed and employed represent additional leisure not increased household production in areas where unemployment is cyclically high however reduced market work is offset by additional home production

productivity and the labor market comovement over the business cycle the productivity driven mortensen pissarides model predicts that labor productivity dened as the ratio of output to employment is strongly correlated with employment unemployment vacancies and wages whereas these correlations were argued to be much weaker in the data especially since the mid 1980s we rst document that the size of these discrepancies between the data and the model becomes substantially smaller if employment data from the current population survey is used in measuring productivity instead of the commonly used employment data from the current employment statistics second we show that incorporating time to build and a stochastic value of home production helps reconcile the quantitative performance of the model with the data with stochastic productivity being the key determinant of the business cycle dynamics of the model
