institutional constraints and deforestation an application to mexico 1 introduction in many tropical regions a key factor influencing deforestation is thought to be the lack of effective property rights and other institutional structures controlling access to and use of forests 1 where such institutions exist they limit access to and conversion of forest land thus acting as a deterrent to deforestation in the absence of formal ownership rules traditional common property regimes in some forested regions have also proven to be effective in controlling the open access deforestation problem gibson 2001 larson and bromley 1990 richards 1997 in short formal and informal institutions can influence the process of forest loss by imposing increased costs of conversion on farmers who clear forest land this article is concerned with analyzing the role of formal and informal institutions as constraints on the conversion of forest land to agriculture in developing countries the perspective on institutions adopted here follows the approach of north 1990 who defines institutions as humanly devised constraints that shape human interaction and that affect the performance of the economy by their effect on the costs of exchange and production in analyzing the relation between institutional constraints and the amount of forest land converted for use by smallholders this article makes several contributions first it demonstrates that if institutions raise the costs of land conversion then it is possible to utilize an agricultural household model to formalize the resulting impacts on the amount of converted land used by all farming households moreover the equilibrium level of land cleared will differ under conditions of no institutional constraints that is the pure open access situation compared to c onditions where effective institutions exist to control land conversion because institutions raise the cost of land clearing more land should be converted under pure open access 2 this in turn implies that the existence of institutional constraints prevents the adjustment of the stock of converted land to the long run equilibrium desired by agricultural households which is the amount of land that could be cleared under open access a dynamic panel analysis is therefore employed to test the hypothesis that the presence of institutions to control agricultural conversion can significantly affect deforestation the model of land expansion is applied to the case of mexico in the pre nafta north american free trade agreement reform era 1960 85 during this period the existence of ejido or communal land ownership for the vast majority of forest land meant that strong institutional controls may have restricted the rate of adjustment in the amount of new land converted and thus limited agricultural expansion sarukhan and larson 2001 the analysis also has direct relevance for the post nafta period particularly because the 1992 land reforms sanction changes in the traditional ejido land ownership structure ii a pure open access model of forest land conversion the following model of forest conversion is based on an approach similar to that of cropper et al 1999 lopez 1997 1998a and panayotou and sungsuwan 1994 assume that the economic behavior of all j rural smallholder households in the agricultural sector of a developing country can be summarized by the behavior of a representative jth household although the representative household is utility maximizing it is a price taker in both input and output markets farm and off farm labor of the household are assumed to be perfect substitutes such that the opportunity cost of the household s time i e its wage rate is exogenously determined the household s behavior is therefore recursive in the sense that the production decisions are made first and then the consumption decisions singh et al 1986 in any time period t let the profit function of the representative agricultural household s production decisions be defined as 1 max pi p w w

property rights externalities and resource degradation locating the tragedy abstract resource degradation in the third world is largely driven by the demands of farm households for fuelwood and land for agriculture since resources are often controlled through indigenous systems of property the tragedy of the commons has been used to explain resource degradation as a result private property is suggested as a solution to resource degradation a dynamic model capable of examining household incentives for resource use under private and common property is developed results of the model reject the conventional wisdom that gives rise to the presumed optimality of private individual property in natural resources and the correlated indictment of group management regimes

international trade and renewable resources under asymmetries of resource abundance and resource management this paper examines the interaction between relative resource abundance and resource management regimes in determining trade patterns and gains from trade in a two country model with a renewable resource a model developed by brander and taylor brander ja taylor ms 1997b resour energy econ 19 267 297 is extended it is shown that relative resource abundance determines trade patterns if resource abundance is similar in both countries and the relative demand for the resource good is moderate or if resource abundance is sufficiently different and the relative demand is not so high otherwise a difference in resource management regimes determines trade patterns even under an open access regime the resource scarce country gains from trade unless resource abundance is similar and the relative demand is low

frontiers and sustainable economic development exploiting new resource frontiers such as agricultural land and mineral reserves is a fundamental feature of economic development in poor economies yet frontier based development is symptomatic of a pattern of economy wide resource exploitation in developing economies that a generates little additional economic rents and b what rents are generated are not being reinvested in other sectors such development is inherently unsustainable the following paper explains this phenomenon and provides evidence that long run expansion of agricultural land and oil and natural gas proved reserves across poor economies is associated with lower levels of real income per capita the paper proposes a frontier expansion hypothesis to explain why the structural economic dependence of these economies on frontier land expansion and resource exploitation is not conducive to sustained long run growth the key to sustainable economic development in poor economies will be improving the economic integration between frontier and other sectors of the economy targeting policies to improved resource management in frontier areas and overcoming problems of corruption and rent seeking in resource sectors

the impact of unemployment insurance on job search evidence from google search data job search is a key choice variable in theories of labor markets but is difficult to measure directly we develop a job search activity index based on google search data the google job search index gjsi we validate the gjsi with both survey and web based measures of job search unlike those measures the gjsi is high frequency geographically precise and available in real time we demonstrate the gjsi s utility by using it to study the effects of unemployment insurance policy changes between 2008 and 2014 we find no evidence of an economically meaningful effect of these changes on aggregate search

constrainedly fair job assignments under minimum wages a number of jobs are to be assigned to a greater number of workers while having to abide by the law of minimum wages firms must determine who should be assigned which job and at what salary in such situations fair envy free allocations usually fail to exist to cope with this situation this paper proposes a new concept of fairness called constrained fairness among the set of constrainedly fair allocations the so called constrainedly fair and minimal allocations are of particular interest the reason for this is that the salaries are not only compatible with the minimum wages they are also optimal from the standpoint of cost minimizing firms and the assignment of jobs is efficient from the viewpoint of workers a convergent dynamic procedure that identifies constrainedly fair and minimal allocations is proposed furthermore strategic properties of the mechanism are derived and two notions of efficiency are evaluated

optimal farm size in an uncertain land market the case of kyrgyz republic this article applies a real options model to the problem of land development making use of the 1998 2001 kyrgyz household budget survey we show that when the hypothesis of decreasing return to scale holds the relation between the threshold value of revenue per hectare and the amount of land cultivated is positive in addition the relation between the threshold and the amount of land owned is positive in the case of continuous supply of land and negative when there is discontinuous supply of land the direct consequence is that in the first case smaller farms will be more willing to rent land and exercise the option where in the second case larger farms will exercise first the results suggest three main conclusions i the combination of uncertainty and irreversibility is an important factor in land development decisions ii farmer behavior is consistent with the continuous profit maximization model and iii farming unit revenue tends to be positively related to farm size once uncertainty is properly accounted for

deforestation and the rule of law in a cross section of countries relationships between deforestation and population pressure income growth and insecure property rights are examined with data from 120 countries insecure property rights are hypothesized to arise from two sources government instability or inability to enforce ownership and an absence of government accountability the former source is captured by measures of general lawlessness such as guerrilla warfare revolution and frequent constitutional change the latter is proxied by variables indicating the type of government executive frequency of political purges and the existence of an elected legislature general support is indicated for the property rights hypothesis and for the effects of population growth

are unemployment and out of the labor force behaviorally distinct labor force states this paper tests the hypothesis that the classifications unemployed and out of the labor force are behaviorally meaningless distinctions this hypothesis is rejected distinct behavioral equations govern transitions from out of the labor force to employment and from unemployment to employment the evidence reported in this paper is broadly consistent with versions of search theory in which unemployment is a state that facilitates the job search process in an appendix we demonstrate that log concavity of the wage offer distribution implies that the exit rate from unemployment is an increasing function of the rate of arrival of job offers

housing markets with indivisibilities abstract a model of a rental housing market in which houses are treated as indivisible commodities is presented a recursive equation that determines a competitive equilibrium is provided and it is argued that this competitive equilibrium is representative of the set of all competitive equilibria using this representative equilibrium several propositions on comparative statics are considered that have to do with how the competitive rents change when certain parameters of the model change

the general equilibrium impacts of unemployment insurance evidence from a large online job board abstract during the great recession u s unemployment benefits were extended by up to 73 weeks theory predicts that extensions increase unemployment by discouraging job search a partial equilibrium effect using data from the large job board careerbuilder com i find that a 10 increase in benefit duration decreased state level job applications by 1 but had no robust effect on job vacancies job seekers thus faced reduced competition for jobs a general equilibrium effect calibration implies that the general equilibrium effect reduces the impact of unemployment insurance on unemployment by 39

environmental externalities in traditional agriculture and the impact of trade liberalization the case of ghana abstract this paper provides a framework for the evaluation of trade policies that explicitly considers the effects of such policies on the environmental resources biomass in doing this we estimate the effects of biomass as a factor of agricultural production and test the hypothesis that farmers efficiently exploit biomass a resource held in common property the main findings are i biomass is an important factor of production in ghanian agriculture ii the biomass resource is exploited beyond the socially optimal level iii a deepening of trade liberalization is likely to induce further losses of biomass and deforestation and iv national income is likely to fall in response to further trade liberalization

job search and unemployment insurance new evidence from time use data article i nfo this paper provides new evidence on job search intensity of the unemployed in the u s modeling job search intensity as time allocated to job search activities the major findings are 1 the average u s unemployed worker devotes about 41 min to job search on weekdays which is substantially more than their european counterparts 2 workers who expect to be recalled by their previous employer search substantially less than the average unemployed worker 3 across the 50 states and d c job search is inversely related to the generosity of unemployment benefits with an elasticity between 1 6 and 2 2 4 job search intensity for those eligible for unemployment insurance ui increases prior to benefit exhaustion and 5 time devoted to job search is fairly constant regardless of unemployment duration for those who are ineligible for ui

price quantity strategic market games this paper is yet another in a rapidly growing series e g 2 11 on strategic approaches to economic equilibrium our aim here is to make precise the remark implicitly due to bertrand 1 or 10 ch 4 5 that if the agents in an economy use price setting strategies then the strategic nash equilibria will in fact be walrasian and this without any assumption of a large number of small agents however in our models not only prices but also quantities are set by the agents thus it might actually be more appropriate to call them bertrand cournot types of models we begin with a standard walras exchange economy with a finite number of traders and commodities this is recast as a game in strategic form in essentially two different ways there is a trading post for each commodity to which traders send contingent statements about how much they wish to buy and sell and at what prices in model 1 the trading point is determined by the intersection of the aggregate supply and demand curves in model 2 trade takes place so as to meet as many contingent statements as possible each buyer whose orders are filled pays the price he quoted using a fiat money which can be borrowed costlessly and limitlessly but after trade is over there is a settlement of accounts and a penalty is levied on those who are bankrupt no attempt is made to model the penalty in any detail it is simply described in the form of a disutility but this in turn may be imagined to stem from confiscation of assets see remark 5 or the necessity of procuring highly priced loans etc call a noncooperative equilibrium active if it turns out that no trader is isolated i e trapped as the sole buyer or seller at some trading post then our results may be described as follows in model 1 the active2 n e of the game coincide with the c e of the market furthermore there is a subset of tight active n e which also coincide with the c e and each n e in this subset is strong

estimating labor supply and production decisions of self employed farm producers abstract this paper proposes a model oriented towards integrating farm households production and consumption decisions into a unified theoretical and econometric framework it is argued that in contrast with other forms of economic organization farm households utility and profit maximization decisions are not likely to be independent econometric estimation of a farm household model using canadian data suggests that utility and profit maximizing decisions are not indeed independent and moreover that there are significant gains in explanatory power and efficiency by estimating the consumption and production equations jointly

links between economic liberalization and rural resource degradation in the developing regions this paper examines evidence of the effects of economic liberalization and globalization on rural resource degradation in developing countries the principal resource effects of concern are processes of land use change leading to forestland conversion degradation and deforestation the main trends in globalization of interest are trade liberalization and economy wide reforms in developing countries that have opened up the agroindustrial sectors thus increasing their export orientation such reforms have clearly spurred agroindustrialization rural development and economic growth but there is also concern that there may be direct and indirect impacts on rural resource degradation the direct impacts may occur as increased agricultural activity leads to conversion of forests and increased land degradation from unsustainable production methods however there may also be indirect effects if agroindustrial development displaces landless near landless and rural poor generally who then migrate to marginal agricultural lands and forest frontier regions this paper explores these direct and indirect effects of globalization and agroindustrialization on rural resource degradation both generally plus through examining case study evidence the paper focuses in particular on the examples of structural adjustment trade liberalization and agricultural development in ghana and maize sector liberalization in mexico under north american free trade agreement nafta

the impact of the potential duration of unemployment benefits on the duration of unemployment abstract this paper examines the impact of the potential duration of unemployment insurance ui benefits on unemployment in the united states first we use a large sample of household heads to examine differences in the unemployment spell distributions of ui recipients and nonrecipients sharp increases in the escape rate from unemployment both through recalls and new job acceptances are apparent for ui recipients around the time of benefits exhaustion such increases are not apparent at similar points of spell duration for nonrecipients second our analysis of accurate administrative data from 12 states indicates that a one week increase in potential benefit duration increases the average duration of the unemployment spells of ui recipients by 0 16 to 0 20 weeks

deforestation and development in a small open economy abstract our economy faces world prices and starts with a large endowment of land in forest and a small endowment of land in agriculture clearing of forested land yields marketable timber and a unit of land for agriculture early the high price of agricultural land drives the clearing process later the profit from marketing timber from the cleared land drives the process dates of phase transitions are endogenous we also set out a submodel of perpetual cyclic clearing and reforesting and show that it when cyclical harvesting regrowing is optimal the extent of clearing can be relatively large

examining the externality of unemployment insurance on children s educational achievement i exploit differences in the generosity of unemployment insurance ui benefits across states and over time to investigate the link between ui and children s academic achievement estimates show that a 1 increase in maximum weekly ui benefits reduces the probability that a child repeats a grade by around 0 03 percentage points the effect is concentrated among children of low and middle income families this paper s findings which are the first in the literature to show evidence of a positive effect of ui on children s educational outcomes provide insight into the role of ui in the human capital accumulation of children jel i20 i38 j65

natural resources agriculture and property rights abstract the study explores empirically forest resource and soil quality degradation under different property rights regimes in a subsistence agriculture framework the quantitative analysis is a direct test of the theoretical hypothesis of larson and bromley 1990 larson b bromley d 1990 property rights externalities and resource degradation locating the tragedy journal of development economics 33 2 that common property and private property rights may lead to similar incentives for resource protection a household model is formulated and applied empirically with data from indonesia to test rates of forest biomass and soil quality degradation under private and common property rights results show that the two regimes may equal each other by including bequest value sensitivity analysis is conducted by changing model parameters

unemployment insurance recall expectations and unemployment outcomes this paper empirically examines the importance of explicitly accounting for the layoff rehire process in the analysis of unemployment outcomes in the united states we find that the spells of individuals who initially expect to be recalled account for much more of the unemployment of unemployment insurance ui recipients than do spells actually ending in recall our results indicate that the recall and new job escape rates from unemployment have quite different time patterns and are often affected in opposite ways by explanatory variables we also find that the probability of leaving unemployment both through recalls and new job finding increases greatly around the time that ui benefits lapse over the past fifteen years many studies have empirically analyzed the determinants of individual unemployment spell durations in the united states much of this literature has used a job search framework in which the unemployed are viewed as permanently displaced workers who are unattached to jobs the possibility of recall to a former job a process not requiring search has been omitted from explicit consideration in the majority of these studies 2 an explicit treatment of the layoff rehire process is necessary for a proper understanding of the determinants of unemployment durations and of the impacts of unemployment policies in the united states for at least three reasons first temporary layoffs in which workers are often rehired by their original employers are a quantitatively quite important feature of the u s labor market 3 second expectations concerning the likelihood of recall are likely to affect the responses of employers and unemployed workers to labor market interventions such as reemployment bonuses and subsidies

large indivisibles an analysis with respect to price equilibrium and fairness an exchange economy is considered in which there are a finite number of individuals the same number of indivisibles and a fixed amount of a divisible good each individual consumes exactly one of the indivisibles and a certain quantity of the divisible good the existence of prices corresponding to pareto efficient allocations is proved it is also shown that this economy possesses fair allocations income fair allocations coalition fair allocations and pareto efficient egalitarian equivalent allocations in this study the effect of including large indivisibles in an exchange economy will be analyzed the analysis will be carried out with respect to the existence of price equilibrium and with respect to the existence of different forms of fairness the economy consists of a finite number of individuals the same number of indivisibles and a fixed amount of a divisible good it is assumed that each individual consumes exactly one of the indivisibles and some quantity of the divisible good we may interpret the indivisibles as being professions or houses the relationship between price equilibrium and a pareto efficient allocation is well known and proved in a number of cases under different assumptions about preferences and commodities for a standard economy see e g debreu 5 in case of nonconvexities which may also describe a certain type of indivisibility we may have an exact relationship in economies with a continuum of individuals see e g hildenbrand 11 but otherwise an approximate relationship obtains the degree of approximation depends on the degree of nonconvexities in preferences and not on the number of individuals see e g arrow and hahn 1 we will prove the existence of prices characterizing a pareto efficient allocation in a case where the indivisibles play an essential role and where approximate results would be too approximate the indivisibles may be considered large for the individual compared to his total consumption the theory of fairness has developed considerably during the seventies different kinds of concepts of fairness have been introduced and analyzed see daniel 41 foley 81 pazner and schmeidler 121 and schmeidler and vind 141 among others normally these authors have considered models with divisible goods or an infinite number of individuals for exchange economies the existence of fair allocations an envy free and pareto efficient allocation has been proved in

agricultural expansion and deforestation modelling the impact of population market forces and property rights abstract this paper compares four different modelling approaches to agricultural expansion and deforestation and explores the implications of assumptions about the household objectives the labour market and the property rights regime a major distinction is made between population and market based explanations many of the popular policy prescriptions are based on the population approach assuming subsistence behaviour and limited market integration within a more realistic particularly for the long term effects market approach well intentioned policies such as agricultural intensification programmes may boost deforestation many forest frontier contexts are also characterized by forest clearing giving farmers land rights deforestation becomes an investment to the farmer and a title establishment strategy land titling and credit programmes may therefore increase deforestation

environmental degradation in developing countries households and the reverse environmental kuznets curve abstract we propose an alternative explanation for the inverted u shape relationship between income and environmental degradation in developing countries production and consumption patterns of rural households are the main cause of environmental damage with a conventional household model we demonstrate that the so called environmental kuznets curve may arise when the restrictive assumption of a set of perfect markets for factors and commodities is relaxed depending on the criterion or indicator that is used to represent environmental pressure however we demonstrate that the reverse may also hold this finding highlights the importance of selecting the appropriate dependent variable in regression analyses

labor market effects of unemployment insurance design with the emergence of the great recession unemployment insurance ui is once again at the heart of the policy debate in this paper we review the recent theoretical and empirical evidence on the labor market effects of ui design we also discuss policy issues related to ui design including the structure of benefits the role of liquidity constraints and the pros and cons of a ui system in which the generosity of ui benefits is varying over the business cycle finally we identify potential areas of future research

economic growth and environmental degradation the environmental kuznets curve and sustainable development abstract in this paper we critically examine the concept of the environmental kuznets curve ekc it proposes that there is an inverted u shape relation between environmental degradation and income per capita so that eventually growth reduces the environmental impact of economic activity the concept is dependent on a model of the economy in which there is no feedback from the quality of the environment to production possibilities and in which trade has a neutral effect on environmental degradation the actual violation of these assumptions gives rise to fundamental problems in estimating the parameters of an ekc the paper identifies other econometric problems with estimates of the ekc and reviews a number of empirical studies the inference from some such ekc estimates that further development will reduce environmental degradation is dependent on the assumption that world per capita income is normally distributed when in fact median income is far below mean income we carry out simulations combining ekc estimates from the literature with world bank forecasts for economic growth for individual countries aggregating over countries to derive the global impact within the horizon of the bank s forecast 2025 global emissions of so 2 continue to increase forest loss stabilizes before the end of the period but tropical deforestation continues at a constant rate throughout the period

on the job search and wage dispersion new evidence from time use data this paper provides new evidence on time devoted to job search by the employed in the u s i find that search effort decreases with the current wage with an elasticity between 0 7 and 1 3

the interaction of population growth and environmental quality an important question for policy is whether holding constant per capita income and other relevant factors population pressures have a significant effect upon environmental degradation the authors examine the effect of population pressures upon deforestation in 64 developing countries in an attempt to provide relevant empirical findings data on deforestation were drawn from the food and agriculture organizations production yearbook results suggest that a relationship exists between per capita income and deforestation and that for africa rural population density shifts the relationship upward the increase in the rate of deforestation levels off as income increases the rate of growth in per capita income also has a significant negative impact upon deforestation although the magnitude of the effect is small the authors close in stressing that reducing the rate of population growth is not necessarily the best way to reduce the rate of deforestation deforestation in developing countries is really a problem of market failure since property rights are often neither defined nor enforced there is essentially no private cost of deforestation with no long term stake in the land people have no incentive to use land efficiently this situation must be addressed in conjunction with the problems of poverty and population growth

can welfare abuse be welfare improving abstract i analyze quantitatively a model of labor search with unemployment insurance ui savings voluntary quits and various labor attachment requirements in particular i study welfare consequences of a powerful reform giving ui entitlement to workers quitting their jobs voluntarily in order to search for another one results of the model calibrated to the us labor market show that there may be significant welfare gains associated with pursuing a generous entitlement policy for quitters as compared to the us status quo moreover i employ the assumption of monetary search costs and show that it can explain the empirically documented unemployed worker search behavior finally by inducing different unemployment benefit eligibility requirements the model identifies a concrete policy that could help us understand differences in the unemployment rate match quality and income inequality between the us and europe

peasant household behaviour with missing markets some paradoxes explained a model of peasant household behavior under varying degrees of household specific food and labor market failures is constructed to show that these structural features can explain several well known patterns of peasant response which have often been attributed to peculiar motives presumed specific to peasants the model explains sluggish response to cash crops prices and high instability in perceived food and labor scarcities the key role of manufactured consumer goods prices in stimulating peasants effort in cash crops production the effectiveness of taxation as opposed to incentives in stimulating cash crops production and the key role of technological change in food production to enhance cash crop production results are obtained analytically in the case of one market failure and by numerical simulation with more than one

changing political regimes and tropical deforestation expansion of agriculture is a main cause of tropical deforestation government policies and weak property rights contribute to this process by encouraging landowners and landless to accelerate land clearing using panel data common to previous studies we add the dimension of new political regimes democratic and non democratic and investigate how the rate of agricultural land expansion in tropical countries depends on the nature and persistence of each regime we find that both new autocratic and democratic regimes have accelerated the expansion of agricultural land thus yielding support to some of the findings in the earlier literature interesting differences emerge between regions with the impact being most pronounced in latin america we interpret these results mainly in the context of increasing tenure and ownership insecurity which in turn is driven by the tendency of new regimes to implement land reforms as a form of social and economic policy or voter payback the argument is developed more formally using a simple competitive land use model that incorporates political regime dependent confiscation risk and agricultural subsidy policy

the economics of tropical forest land use options tropical deforestation is generally characterized as conversion of forest land to alternative uses notably agriculture this would suggest the need for rational decision making concerning the optimal allocation of tropical forest land between competing uses the following paper explores this problem by devising rules for determining optimal land use allocation between timber and agriculture at the stand and forest levels a complementary intertemporal model for optimal allocation of forest land to agricultural conversion at the forest level is also developed and used to derive a demand relationship for agricultural conversion which is then approximated through empirical estimation

unemployment insurance take up rates in an equilibrium search model abstract from 1989 to 2012 on average 23 of those eligible for unemployment insurance ui benefits in the us did not collect them to understand the implications of these unclaimed benefits we develop a directed search model with an endogenous ui take up rate in equilibrium ui collectors have longer unemployment durations relative to non collectors the difference results from two forces a consumption effect and a private information effect as ui collection histories are unobservable we characterize both effects analytically and quantitatively with an endogenous take up rate the unemployment rate and average duration of unemployment respond significantly slower to changes in the ui benefit level relative to the standard model with a 100 take up rate the private information effect on non collector job finding rates plays an important role in this result

time use during the great recession using data from the american time use survey between 2003 and 2010 we document that home production absorbs roughly 30 percent of foregone market work hours at business cycle frequencies leisure absorbs roughly 50 percent of foregone market work hours with sleeping and television watching accounting for most of this increase we document significant increases in time spent on shopping child care education and health job search absorbs between 2 and 6 percent of foregone market work hours we discuss the implications of our results for business cycle models with home production and non separable preferences jel codes d13 e32 j22

moral hazard vs liquidity and optimal unemployment insurance this paper presents new evidence on why unemployment insurance ui benefits affect search behavior and develops a simple method of calculating the welfare gains from ui using this evidence i show that 60 percent of the increase in unemployment durations caused by ui benefits is due to a liquidity effect rather than distortions on marginal incentives to search moral hazard by combining two empirical strategies first i find that increases in benefits have much larger effects on durations for liquidity constrained households second lump sum severance payments increase durations substantially among constrained households i derive a formula for the optimal benefit level that depends only on the reduced form liquidity and moral hazard elasticities the formula implies that the optimal ui benefit level exceeds 50 percent of the wage the exact identification approach to welfare analysis proposed here yields robust optimal policy results because it does not require structural estimation of primitives

the spike at benefit exhaustion leaving the unemployment system or starting a new job in this paper we review the literature on the spike in unemployment exit rates around benefit exhaustion and present new evidence based on administrative data for a large sample of job losers in austria we find that the way unemployment spells are measured has a large effect on the magnitude of the spike at exhaustion both in existing studies and in our austrian data spikes are typically much smaller when spell length is defined by the time to next job than when it is defined by the time spent on the unemployment system in austria the exit rate from registered unemployment rises by over 200 at the expiration of benefits while the hazard rate of re employment rises by only 20 the difference between the two measures arises because many individuals leave the unemployment register immediately after their benefits expire without returning to work the modest spike in re employment rates implies that most job seekers do not wait until their ui benefits are exhausted to return to work fewer than 1 of jobless spells have an ending date that is manipulated to coincide with the expiration of ui benefits this abstract was borrowed from another version of this item

poverty policies and deforestation the case of mexico this study examines the determinants and policy implications of deforestation in mexico and includes a brief review of the relevant empirical literature and a description of the theoretical model land use patterns and socioeconomic and physiogeographic factors are determinants data were obtained from digital maps of land use and soils and the 1990 population and 1991 agricultural censuses a simple 2 period equation formalizes the relationship between deforestation and poverty government policies and local land tenure in period 1 representative producers in municipalities have 4 options in allocating labor time wage generation agricultural production deforestation on land without clear property rights and investment in technology during period 2 the options are to farm on available land and deforested areas or work in the wage sector findings reveal that 1 communal land tenure ownership by the ejido did not increase deforestation 2 pricing that favors maize production which is very land intensive increased deforestation and technical assistance reduced deforestation and 3 poverty was related to higher rates of deforestation prices were the most important immediate factor in unsustainable resource use but other factors had an impact the government policy mix did not support sustainable development reduced subsidies would benefit the environment the government should provide safety nets to increase the level of rural investment and reduce poverty and should improve land productivity with technical inputs trade liberalization and elimination of subsidies should be sensitive to the poors need for real wages

job search by employed and unemployed youth analysis of data from the new youth cohort of the national longitudinal survey yields evidence that young unemployed job seekers chose higher levels of search effort as measured by number of methods used and time spent per method and lower reservation wages relative to offered wages than did comparable employed job seekers in 1981 these differences in search choices at least partly explain differences in search outcomes between the two groups unemployed searchers apparently were more likely than employed searchers to gain new employment and the wages they obtained were slightly lower the author argues that the greater search effort by unemployed job seekers is due to the higher costs of search they bear because of foregone earnings

reprint of the general equilibrium impacts of unemployment insurance evidence from a large online job board abstract during the great recession u s unemployment benefits were extended by up to 73 weeks theory predicts that extensions increase unemployment by discouraging job search a partial equilibrium effect using data from the large job board careerbuilder com i find that a 10 increase in benefit duration decreased state level job applications by 1 but had no robust effect on job vacancies job seekers thus faced reduced competition for jobs a general equilibrium effect calibration implies that the general equilibrium effect reduces the impact of unemployment insurance on unemployment by 39

household composition labor markets and labor demand testing for separation in agricultural household models this paper tests the separation of farm labor supply and labor demand decisions using the observation that household composition is an important determinant of farm labor use with nonseparation after assessing the conditions under which the test has power against several alternatives an empirical model is developed to test the proposition that farm employment is independent of family composition the model is estimated on a data set from rural java the null hypothesis that farm labor allocation decisions are independent of household structure is not rejected the results are robust to different specifications of the labor demand function copyright 1992 by the econometric society

unemployment insurance and cigarette smoking abstract we provide evidence for the causal relationship between unemployment insurance ui and individuals smoking behavior using the 1995 2011 current population survey tobacco use supplement data our identification relies on the exploitation of the exogenous variations of the maximum ui weekly benefits across states and over years instead of focusing on all unemployed people we concentrate on those who are eligible for ui benefits we find that when the maximum ui weekly benefit level increases by 100 smoking cessation increases by approximately 2 9 percentage points among the ui eligible unemployed the results are robust to various model specifications we also explore the mechanism and find suggestive evidence that the increase in the maximum ui weekly benefit leads to a decrease in the probability of over work of the respective spouse moreover the unemployed who are less educated are more responsive to the increasing ui benefits

agricultural intensification common property resources and the farm household this paper evaluates the impact of agricultural price and intensification policies for common property resources and welfare of rural communities in developing countries in doing so we develop a new model for the farm household that has analytical advantages over the traditional one and that has significant potential for empirical application the major findings are technical assistance that increase productivity of land intensive agricultural outputs cereals livestock etc cause degradation of the communal resources and may cause immiserization policies that increase the prices of these goods cause identical effects by contrast similar policies applied to labor intensive outputs vegetables tubers etc contribute to improve the common resources and to increase the welfare of the rural communities

duration dependence and labor market conditions evidence from a field experiment this article studies the role of employer behavior in generating negative duration dependence the adverse effect of a longer unemployment spell by sending fictitious resumes to real job postings in 100 u s cities our results indicate that the likelihood of receiving a callback for an interview significantly decreases with the length of a worker s unemployment spell with the majority of this decline occurring during the first eight months we explore how this effect varies with local labor market conditions and find that duration de pendence is stronger when the local labor market is tighter this result is consistent with the prediction of a broad class of screening models in which employers use the unemployment spell length as a signal of unobserved productivity and recognize that this signal is less informative in weak labor markets jel code j64

a quantitative analysis of unemployment benefit extensions abstract extensions of unemployment insurance ui benefits have been implemented in response to the great recession this paper measures the effect of these extensions on the unemployment rate using a calibrated structural model featuring job search and consumption saving decisions skill depreciation and ui eligibility the ongoing ui benefit extensions are found to have raised the unemployment rate by 1 4 percentage points which is about 30 of the observed increase since 2007 moreover the contribution of the ui benefit extensions to the elevated unemployment rate increased during 2009 2011 while the number of vacancies recovered the successive extensions kept search intensity down

training and search during unemployment displaced workers often experience large losses in earnings even a long time after reemployment training programs during unemployment mitigate these losses but also affect the unemployed s willingness to search this paper analyzes how mandatory training programs affect the optimal design of unemployment insurance and how the training intensity should evolve during the unemployment spell the introduction of training reverses the optimal consumption dynamics during the unemployment spell and makes it optimal to incentivize the long term unemployed to find employment despite the depreciation of their human capital targeting training programs towards the long term unemployed however is optimal only if the fall in human capital upon displacement is small relative to the depreciation during unemployment

shopping externalities and self fulfilling unemployment fluctuations we propose a novel theory of self fulfilling fluctuations in the labor market a firm employing an additional worker generates positive externalities on other firms because employed workers have more income to spend and have less time to shop for low prices than unemployed workers we quantify these shopping externalities and show that they are sufficiently strong to create s complementarities in the employment decisions of different firms and to generate multiple rational expectations equilibria equilibria differ with respect to agents rational expectations about future unemployment we show that negative shocks to agents expectations lead to fluctuations in vacancies unemployment labor productivity and the stock market that closely resemble those observed in the us during the great recession

the existence and computation of competitive equilibria in markets with an indivisible commodity abstract this paper considers an exchange economy called a generalized assignment market in which sellers and buyers trade one indivisible commodity possibly with product differentiation for a perfectly divisible commodity the existence of a competitive equilibrium in this economy is proved using kakutani s fixed point theorem this existence theorem is applied to a production economy in which sellers are formulated as producers with convex cost functions two examples of housing markets are provided and their competitive equilibria are numerically calculated

land use and income diversification comparing traditional and colonist populations in the brazilian amazon this article compares and analyzes land use and income diversification among two distinct groups of farmers in the brazilian amazon recent colonists in ouro preto do oeste rondonia and traditional long term residents along the tapajos river para we investigate the hypothesis that farmers who diversify their cash income sources clear less forest on an annual basis and we compare these livelihood choices across colonist and traditional populations in particular we develop a conceptual model based on the household production framework and use econometric models to identify determinants of diversification and forest clearing we find that diversification of agricultural cash crops is negatively correlated with forest clearing by colonists providing limited evidence for the hypothesis other significant covariates of diversification and forest clearing include cash income levels stage in family life cycle cattle ownership and chemical inputs differences in these variables and differences in household response to these variables explain variation in diversification and forest clearing across the two populations

unemployment at risk the policy determinants of labour market exposure to economic shocks this paper examines the vulnerability of labour markets to adverse economic shocks we define labour market exposure as the cumulated amount of excess unemployment generated by a shock before unemployment returns to steady state we use a panel of 19 countries covering the period 1985 2010 to assess the influence of labour market policies on labour market exposure which is also calculated country by country we find that less generous unemployment insurance more active labour market policies or a lower minimum wage imply a trade off between average unemployment and labour market exposure as they help low skilled workers to get out of unemployment at the cost of increased vulnerability to adverse shocks on the other hand reducing the tax wedge is conducive to both lower steady state unemployment and labour market exposure alain de serres and fabrice murtin

deforestation and agricultural productivity in the cote d ivoire an optimal control model is used to determine the optimal steady state forest stock in the cote d ivoire this stock is shown to increase with increases in the forestry returns relative to those in agriculture technological progress in agriculture and increases in the social discount rate serve to lower the optimal steady state forest stock based on an estimated aggregate yield function the optimal forest stock is shown to be most sensitive to changes in the social rate of discount assuming current 1985 technology deforestation appears socially optimal only for values of the discount rate greater than 8

virtual land use and agricultural trade estimating environmental and socio economic impacts abstract liberalization has caused an increase in the global trade of goods and services in particular the value and physical volume of agricultural goods traded have largely increased as the environmental and social consequences of trade are complex they are rarely included in the national and international agricultural policies one reason is that there is a lack of concepts and methods for assessing the environmental and social impacts of trade policies in this paper we develop a method for quantifying and assessing the land use hidden in the export and import of agricultural goods for the case of switzerland for our analysis we focus on arable crops the first methodological step of our research illustrates the spatial relationship of switzerland with countries all over the world through the import and export of land use for arable crops the second step links this spatial dimension with a qualitative assessment of the environmental and socio economic impacts of agricultural land use we applied the method to the case of wheat cultivation within switzerland and import to switzerland the major problem we were confronted with was the availability of data which had both to be reliable and available for the countries wheat is imported from the results show that the calculation of land use is credible in spite of the problems related with data availability the assessment results for each indicator are in agreement with the current situation in the respective countries in addition the aggregation seems to accurately reflect the countries agricultural polices the developed method is used to estimate the overall environmental and socio economic impacts of an increase in wheat imports to switzerland we argue that this method could be applied for anticipating potential impacts of trade agreements still further research is required for fine tuning of the utility functions including a weighting procedure in the aggregation procedure for practical applications important aspects like water shortage should enlarge our limited set of indicators in addition the average impact on a country level was assessed to refine that different agricultural systems ranging from intensive to extensive to organic should be considered beyond our scope was to analyze impacts due to other life cycle stages than the agricultural production for informed decision however information on the whole life cycle of agricultural products is required

rebound effects in agricultural land and soil management review and analytical framework abstract increasing the efficiency of production is the basis for decoupling economic growth from resource consumption in agriculture more efficient use of natural resources is at the heart of sustainable intensification however technical improvements do not directly translate into resource savings because producers and consumers adapt their behaviour to such improvements often resulting in a rebound effect where part or all of the potential resource savings are offset in extreme cases increases in efficiency may even result in higher instead of lower resource consumption the jevons paradox rebound effects are particularly complex in agricultural land and soil management where multiple resources are used simultaneously and efficiency gains aim to lower the need for farmland water energy nutrients pesticides and greenhouse gas emissions in this context quantification of rebound effects is a prerequisite for generating realistic scenarios of global food provision and for advancing the debate on land sparing versus land sharing however studies that provide an overview of rebound effects related to the resources used in agriculture or guidelines for assessing potential rebound effects from future innovations are lacking this paper contributes to closing this gap by reviewing the current state of knowledge and developing a framework for a structured appraisal of rebound effects as a test case the proposed framework is applied to emerging technologies and practices in agricultural soil management in germany the literature review revealed substantial evidence of rebound effects or even jevons paradox with regard to efficiency increases in land productivity and irrigation water use by contrast there were few studies addressing rebound effects from efficiency increases in fertilizer use pesticide application agricultural energy use and greenhouse gas emissions while rebound effects are by definition caused by behavioural adaptations of humans in agriculture also natural adaptations occur such as resistance of pests to certain pesticides future studies should consider extending the definition of rebound effects to such natural adaptations the test case revealed the potential for direct and indirect economic rebound effects of a number of emerging technologies and practices such as improved irrigation technologies which increase water productivity and may thereby contribute to increases in irrigated areas and total water use the results of this study indicated that rebound effects must be assessed to achieve realistic estimates of resource savings from efficiency improvements and to enable informed policy choices the framework developed in this paper is the first to facilitate such assessments

employment risk and job seeker performance using detailed labor recruitment data in combination with randomized variation in individuals outside job opportunities i show that providing job certainty during recruitment leads to substantial job seeker performance gains job seeker performance is highest and effort lowest among those assigned to receive a guaranteed outside job offer where employment risk is eliminated while performance is lowest and effort highest among those receiving no chance of an outside job offer performance among those assigned uncertain outside job offers consistently lies between the two extremes i conjecture that the pattern of results is most consistent with stress induced performance reductions attributable to job uncertainty i rule out several other competing theories

amenity benefits and the optimal allocation of land agricultural land often yields sig nificant amenity benefits that may not be re flected in the prevailing allocation of land be tween agricultural and nonagricultural uses this paper introduces a simple supply demand model that incorporates these benefits in the de termination of optimal land allocation three stage least squares and county level data are used to estimate the supply and demand param eters these estimates confirm the plausibility of the conceptual model results from the con tingent valuation literature illustrate the extent of underallocation of land to agriculture due to existing institutional conditions some correc tive measures and their distributional effects are discussed and quantified jel q24

building sectoral job search indices for the united states abstract this study investigates job search activity in the united states by constructing a set of sectoral job search activity indices based on internet search volumes the indices are positively associated with countercyclical labour market measures including unemployment and layoff rates but are negatively associated with procyclical measures overall our evidence supports previous empirical findings job search intensity is countercyclical which contradicts the theoretical model s prediction

explaining a miracle intensification and the transition towards sustainable small scale agriculture in dryland machakos and kitui districts kenya abstract the transition to sustainable agriculture in tropical small scale farming has been discussed intensively since boserup published her theory on the role of population pressure as a leading factor bosemp s work challenged the malthusian approach to rural transformation recent evidence supports the boserup theory as applied to machakos district kenya this paper aims to establish how much of terracing is directly explained by population density increases as opposed to other district and village level variables by using a retrospective multivariate analysis in machakos and kitui districts kenya the findings suggest that variables such as the distance to major urban markets and the windfall profits from the coffee boom in the late 1970s are at least as important in explaining the investment in the quality of land in machakos and kitui districts

applications and interviews firms recruiting decisions in a frictional labour market i develop a directed search model to study the recruitment decisions of firms competing for workers who ex post differ in two dimensions 1 their match productivity and 2 their probability of accepting a job offer endogenously determined by their choice of application portfolio to attract these workers firms post a recruiting intensity and a hiring standard in addition to terms of trade a higher recruiting intensity is costly but allows the firm to select more applicants for an interview which reveals their productivity the hiring standard solves the tradeoff between immediate hiring and waiting for a potentially better match in the future i characterize equilibrium and find that various outcomes including uniqueness of equilibrium and the cyclicality of recruiting intensity crucially depend on firms recruiting cost and workers search cost calibration of the model to the u s labour market indicates a continuum of equilibria given selection of a particular equilibrium hiring standards are countercyclical while recruiting intensity is procyclical the calibrated model creates more amplification than a standard model without intensive margins and gives rise to procyclical match efficiency when viewed through the lens of a cobb douglas matching function

is it socially efficient to impose job search requirements on unemployed benefit claimants with hyperbolic preferences dellavigna and paserman 2005 and paserman 2008 have shown that imposing job search requirements on sophisticated unemployed benefit claimants with hyperbolic time preferences is pareto improving in that it raises welfare for the unemployed by limiting harmful procrastination and for employees since the enhanced search boosts the job finding rate thereby reducing the contributions required for the funding of benefits this paper demonstrates that the range of pareto improvements is much reduced if the analysis takes into account the fact that benefit claimants may not comply with the requirements especially if the monitoring technology displays imperfections induced by caseworker discretion or measurement error

the strategy structure of two sided matching markets we study two sided markets in which agents are buyers and sellers or firms and workers or men and women the agents are to form partnerships which provide them with satisfaction and at the same time make monetary transfers e g salaries or dowries the core of this market game is shown to have a particularly nice structure so that precise answers can be given to questions concerning comparative statics and manipulability the idea of using walrasian equilibrium as a mechanism for making allocations with desirable properties of fairness and efficiency has been studied extensively the scheme involves having agents specify their supply and demand functions the competitive equilibria are then calculated and allocations are made accordingly in general this procedure may run into two difficulties first nonuniqueness if there are several equilibria there may be no fair way to decide which one should be implemented and second manipulability if there is only one equilibrium an informed agent may be able to influence it by suitably falsifying his demand data however as we will show here using the walrasian mechanism does work remarkably well for a certain class of important markets these are the matching markets of our title and they include markets for single items like houses where it is assumed that traders do not wish to acquire more than one item they also include labor markets in which it is desired to match workers with jobs at suitable salaries academic markets in which students are to be assigned to educational institutions marriage markets where men and women are matched through negotiating of dowries it turns out that in these markets both the problems of nonuniqueness and manipulability can be resolved in a

trade tragedy and the commons we develop a theory of resource management where the degree to which coun tries escape the tragedy of the commons and hence the de facto property rights regime is endogenously determined three forces determine success or failure in resource management the regulator s enforcement power the extent of har vesting capacity and the ability of the resource to generate competitive returns without being extinguished the model can explain heterogeneity across coun tries and resources in the effectiveness of resource management and it predicts that changes in prices population and technology can cause transitions to better or worse management regimes jel p14 q21 q22 q23 q32 many of the world s major renewable resource stocks are in a state of decline this is true for capture fisheries for forests in developing countries and for many measures of the biosphere s health other renewable resources including many species of wildlife marine mammals and coral reefs are also under threat while poverty and government corruption are surely respon sible for some of this record particular emphasis is often placed on the potentially damaging role played by international trade this emphasis is not surprising given that natural resource products are a key export for much of the developing world and property rights over renewable resources are both difficult to define and poorly enforced but property rights are not an immutable country characteristic such as weather mineral deposits or topography they are instead market institutions developed to facilitate transactions and protect scarce resources consequently changes in prices technology and other effects of market integration may alter the de facto property rights regime and lead to impacts quite dif ferent from those predicted by existing analyses the purpose of this paper is to examine renew able resource use within a framework where the enforcement of property rights and hence the efficacy of resource management is endogenously determined we develop a theory where an existing government regulates the use of a renewable resource by a set of agents who have a right to harvest the resource could be a fishery forest stock aquifer etc and we assume it is local and therefore contained within one country the govern ment sets rules limiting harvests but agents may cheat on these allocations and risk punishment property rights are endogenous in this framework because the government must account for agents incentive to cheat as a result the effective protection for the resource or what we refer to as the de facto property rights regime may be far from perfect even though property rights would be perfectly enforced if there was no monitoring problem

time use emotional well being and unemployment evidence from longitudinal data how do unemployed individuals allocate and experience their time how does their time use and emotional experience change once they find a job this article provides new evidence on the time use and emotional well being of unemployed and employed individuals in the united states using longitudinal data from a survey of unemployed workers in new jersey we find evidence that the time spent on home production activities drops sharply at the time of reemployment with the magnitude of the shift in line with previous research using cross sectional time use surveys burda and hamermesh 2010 krueger and mueller forthcoming 1 leisure activities also decrease at the time of reemployment though somewhat less than in cross sectional time use data partly because those finding a job were spending more time on job search activities in the weeks prior to reemployment we also investigate the relationship between unemployment and emotional well being in connection with time use despite the fact that the unemployed spend relatively more time in leisure related activities we find that the unemployed enjoy these activities to a lesser degree

planning timber production with evolving prices and costs the traditional faustmann solution to the timber harvesting problem was developed for an environment in which prices costs and technology were constant recent contributions recognizing the evolution of economic institutions have developed solutions to optimal harvesting problems under a variety of more realistic assumptions nautiyal and fowler 1980 show that the socially desirable rotation in a monopolistic situation is longer than that which maximizes the monopolist s present worth but is shorter than the atomistic rotation p 213 heaps and neher 1979 derive the optimal rotation when the rate of harvest is constrained bare and waggener 1980 investigate the value of timberland when timber prices change using a traditional faustmann model murphy fortson and bethune 1977 deal with an imperfect capital market one problem not addressed by recent contributions concerns the violation of the assumption of constant price and cost functions for timber production this assumption clearly does not hold stumpage prices exhibit substantial short run fluctuations and systematic long run trends for southern pine and douglas fir two species that are potential crops for timber plantations historical evidence demonstrates that stumpage prices relative to other price have grown steadily for the period 1913 1978 the ratio of southern pine stumpage price to prices paid by farmers increased at a 4 annual rate while the same ratio for douglas fir increased at an annual rate of 5 7 1 for douglas fir and southern pine forecasts of prices and costs based on his

skill accumulation in the market and at home abstract an evolving outside option is introduced into a stochastic directed search model with skill loss during non employment using multi spell data from the sipp i show that average reemployment wages are only mildly sensitive to unemployment duration while the job finding probability is highly sensitive to duration with evidence of true duration dependence in both variables though untargeted the model produces a quantitatively accurate decline in the job finding probability and starting wage improving over a model with a fixed outside option the addition of aggregate shocks leads to an nonlinear response of the unemployment and participation rates during and after recessions with more severe recessions resulting in stronger hysteresis

optimal life cycle unemployment insurance we argue that us welfare would rise if unemployment insurance were to be increased for young workers and decreased for old this is because young workers have little means to smooth consumption during unemployment and want jobs to accumulate high return human capital so unemployment insurance is highly valuable to them while the induced moral hazard problem is mild we consider a life cycle model with unemployment risk and endogenous search eort that we calibrate to match us labor market institutions we nd that allowing unemployment replacement rates and other government transfers to decline with age yields sizeable welfare gains which amount to around two thirds of the gains attained under the constrained optimal scheme for unemployment insurance over the life cycle

worker search effort as an amplification mechanism abstract it is well known that the diamond mortensen pissarides model exhibits a strong trade off between cyclical unemployment fluctuations and the size of rents to employment introducing endogenous job search effort reduces the strength of the trade off while bringing the model closer to the data ignoring worker search effort leads to a large upward bias in the elasticity of matches with respect to vacancies merging the american time use survey and the current population survey new evidence in support of procyclical search effort is presented average search effort of the unemployed is subject to cyclical composition biases

incentive compatibility in a market with indivisible goods abstract in a market in which each trader s initial endowment is one unit of an indivisible good there exists an incentive compatible procedure for reaching a competitive allocation this contrasts with some recent results for similar problems

does unemployment insurance crowd out home production abstract in this paper we study the interaction between self insurance and public insurance in particular we provide evidence on a negative correlation between unemployment insurance benefits and home production using the american time use survey atus and the state level unemployment insurance data of the u s the empirical results suggest that moving to a two times more generous state would decrease time spent on home production about 22 for the unemployed then we pursue a quantitative assessment of this empirical finding using a dynamic competitive equilibrium model in which households do home production as well as market production the model is able to generate the empirical facts regarding the unemployment benefits and home production the fact that unemployment insurance benefits crowd out home production is interpreted as a substitution between the two insurance mechanisms against loss of earnings during unemployment spells

the causes of tropical deforestation in ecuador a statistical analysis abstract this paper reports a statistical analysis of the causes of agricultural colonization and land clearing in eastern ecuador the results bolster many of the arguments that have been made about the social forces driving tropical deforestation in general the prospect of capturing agricultural rents stimulates settlement of tree covered hinterlands accordingly the presence of roads and urban centers attracts rural settlement colonists also prefer to go where soils are suitable for crop or livestock production all else remaining the same in addition to being a function of population pressure the extent of land clearing is shown to be a consequence of tenure insecurity these results suggest that institutional reform is needed to encourage conservation of tropical forests

how do financial resources affect the timing of retirement after a job separation this study examines working people between the ages of 50 and 70 years old and the conditions that lead them to decide to retire or not after they experience a job separation based on data from the survey of income and program participation the author finds that among individuals whose jobless spells end in retirement most decide to retire within a year after separation the availability of resources such as social security retirement benefits high net worth and income from defined benefit pensions appear to encourage more rapid labor force exit and retirement rather than supporting job seekers during a long search perhaps surprisingly no correlation between retirement and the unemployment rate occurs but unemployment insurance benefits do delay retirement these results suggest little tolerance for long job searches regardless of labor market prospects and indicate that those who can afford to retire will do so rather quickly

delayed collection of unemployment insurance in recessions contrary to assumptions in the unemployment insurance ui literature this paper argues that unemployed workers do not always lose uncollected ui benefits when they start a new job instead they may postpone the collection of leftover benefits to future unemployment spells further using cross time and cross state variations in ui policies the paper finds empirical evidence that allowing unemployed workers to delay the collection of benefits increases their incentives to find a job during recessions when wages are low job separation rates are high and ui benefits are extended i quantify the effects of the policy of allowing delayed collection of benefits on aggregate unemployment by introducing endogenous search effort benefit eligibility and wage indexed benefits into a standard search and matching framework the model demonstrates how the policy increases the future value of employment even though more generous ui benefits in general reduce the net value of employment using a calibrated model i find that allowing delayed benefit collection raises the proportion of unemployed workers receiving benefits and reduces the unemployment rate during 2009 2012

the lot of the unemployed a time use perspective this paper provides new evidence on time use and subjective well being of employed and unemployed individuals in 14 countries we devote particular attention to characterizing and modeling job search intensity measured by the amount of time devoted to searching for a new job job search intensity varies considerably across countries and is higher in countries that have higher wage dispersion we also examine the relationship between unemployment benefits and job search

the beveridge curve a survey important progress has been made in economists understanding of the beveridge curve from its measurement to its expression in canonical labor market models yet enduring puzzles remain chief among these are the empirical role of vacancies in the recruitment process the amplitude comovement and persistence of cyclical unemployment vacancy dynamics and the sources of lateral shifts in the beveridge curve the synthesis of these themes identifies several priorities for ongoing research including the role of entry costs into vacancy creation in shaping beveridge dynamics the cyclicality of search intensity both off and on the job and its relation to participation and job to job transitions the theory and measurement of mismatch and the sources of hysteresis in unemployment flows
