understanding severance pay determination mandates bargaining and unions while most of the literature on employment protection has focused on governmentmandated severance pay it has recently been documented that a substantial share of severance payments derives from private contracts or collective agreements this paper studies the determination of these payments we analyze the problem of joint bargaining over wages and severance payments and examine the impact of unions on these choices to do so we use a search and matching model with risk averse workers in which we assume that workers may be unionized and that bargaining is over wages and severance pay bargaining results in levels of severance pay providing full insurance which depend on the generosity of unemployment benets and on the job nding rate unions opt for higher levels of severance pay given that their higher wage demands imply reduced job creation calibrated to 8 european economies the model predicts bargained levels of severance pay which are close to those found in reality

efficient methods of measuring welfare change and compensated income in terms of ordinary demand functions a utility maximizing consumer with a completely known system of ordinary demand functions q h p c is considered let p qo and p q be two arbitrary equilibrium situations the problem is to evaluate in which of the situations the utility is higher without knowing the utility function revealed preference theory tells that the ordinary demand functions which are in principle observable contain enough information to solve the problem remaining difficulties are therefore mainly computational we present how the compensated income c i c p qo and the compensated demand h p cl1 are calculated with arbitrary accuracy using only the ordinary demand system our two efficient algorithms also have interesting interpretations in terms of index numbers and consumer surplus measures

labor protection laws and bank loan contracting abstractthis paper examines the impact of labor regulations that restrict firms flexibility to adjust labor resources on the cost of corporate bank loans using within country variation in employment protection legislation across 25 countries i find that increases in employment protection lead to higher loan spreads tighter nonprice loan contract terms and more diffuse loan ownership structure the effects of labor regulations are greater in industries with a higher rate of labor turnover and among borrowers with a higher probability of default these results suggest that rigidities imposed by labor regulations have a significant impact on firms cost of capital

a hedonic travel cost analysis for valuation of multiple components of site quality the recreation value of forest management abstract one benefit of managing forests is that one can alter the qualities of sites the value of changing site qualities however is generally not known this paper develops a formal hedonic travel cost model which can be used to estimate the value of both marginal and non marginal changes to sites the approach accommodates multiple simultaneous changes in site characteristics estimating this model using a set of permits from wilderness areas leads to revealed preference estimates of the recreational value of clear cuts old growth and nine other wilderness attributes

energy consumption and the influencing factors in china a nonlinear perspective abstract different from many studies on energy kuznets curve this paper does not directly consider income factor but conducts a nonlinear study on per capita primary energy consumption and electricity consumption in china whose economic development is considered investment driven in which government macroeconomic policies especially government expenditure plays a very important role in particular this paper attempts to compare the different impacts of government expenditures and the other influencing factors on energy consumption based on the results of the threshold regression in the future with the further development of the economy the driving force of labor population growth will slow down comparing with primary energy the relationship between electricity consumption and its influencing factors will change later and the difference in the effects of the influencing factors is mainly reflected in the formation of capital stock investment and the development of urbanization government expenditure on private goods may not be always as inefficient in energy consumption and cleaner production as previously thought in the literature meanwhile the growth of government expenditure on public goods will become a powerful driving factor which indicates that the government needs to assess its overall impact on energy consumption and energy efficiency when participating in the provision of public goods the paper also found that when studying the issue of energy consumption and regional differences in china the geographic classification of eastern central and western regions may not be appropriate grouping according to energy consumption levels may be one of the better options and the distribution of energy consumption levels in china s provinces is consistent with the distribution of government expenditure levels the estimation results also provide us with important policy implications the government expenditure in education is of great importance and it can produce a strong energy saving effect through technological progress

a utility consistent combined discrete choice and count data model assessing recreational use losses due to natural resource damage abstract a two stage budgeting approach can often be taken when analyzing consumer choice situations in this paper we examine the particular situation where a consumer makes purchases of a discrete commodity of which there are a number of brands in the first stage the consumer decides how many purchases to make in the second stage the consumer decides how to allocate these purchases across brands our econometric approach to this type of situation uses a utility consistent combined discrete choice and count data model the second stage which is specified as a multinomial choice model produces a price index for the commodity which is used to estimate the first stage which is specified as a count data model we apply the model to recreational demand behavior in alaska in order to estimate the welfare losses suffered by recreational users due to the exxon valdez oil spill these results may provide useful input to government agencies attempting to estimate the appropriate level of taxes fines or regulations for deterring damage to the environment

chile the unbearable burden of inequality summary chile has been cited as a successful case of development relatively fast economic growth over almost two decades has been accompanied by a significant reduction in absolute poverty however persistent economic growth and a mostly pro poor structure of public expenditures have not been sufficient to reduce inequality in one of the most unequal countries in the world we show that the key factors explaining this persistent inequality have been a low level of fiscal expenditures caused by low tax revenues that have not permitted enough public investment in human capital and knowledge generation and diffusion

political economy of public policies insights from distortions to agricultural and food markets the agricultural and food sector is an ideal case for investigating the political economy of public policies many of the policy developments in this sector since the 1950s have been sudden and transformational while others have been gradual but persistent this paper reviews and synthesizes the literature on trends and fluctuations in market distortions and the political economy explanations that have been advanced based on a rich global data set covering a half century of evidence on commodities countries and policy instruments the paper identifies hypotheses that have been explored in the literature on the extent of market distortions and the conditions under which reform may be feasible

site aggregation in a random utility model of recreation random utility models are commonly used to model the choice among a set of alternatives often due to data or computational constraints the analyst must use aggregated alternatives to estimate the model these aggregates are defined by averaging characteristics of alternatives over prespecified groups in this analysis we demonstrate that unless some very restrictive conditions hold the use of aggregated alternatives will lead to biased results then using a data set of recreational fishing in wisconsin we show the effects that this bias can have on the results estimated from the model

a repeated nested logit model of atlantic salmon fishing participation and site choice for atlantic salmon fishing are modeled in the context of a repeated three level nested logit model consumer s surplus measures are derived for different levels of species availability in the penobscot river the most important salmon river in new england for comparison six other travel cost models are estimated these include restrictive cases of the nested logit model a partial demand model and two single site demand models comparisons across these models indicate the importance of modeling the participation decision including income effects and of adopting a nested logit structure rather than a single level logit structure

the effects of fiscal policy on co2 emissions evidence from the u s a abstract this paper examines the effects of fiscal policy on co2 emissions using vector autoregressions on u s quarterly data from 1973 to 2013 in particular we analyze the short and mid term interactions between fiscal policy and emissions by using sign restrictions to identify the policy shocks we construct the impulse responses to linear combinations of fiscal shocks corresponding to the scenarios of deficit financed spending and deficit financed tax cuts to consider possible variations of the effect of fiscal policy according to the sources of pollution we distinguish between production and consumption generated co2 emissions the results point out that the implementation of expansionary fiscal spending provides an alleviating effect on emissions from both sources of the pollutant whereas deficit financed tax cuts are associated with an increase on consumption generated co2 emissions the exact pattern of the effects depends on the source of emissions the scenario of fiscal policy that is implemented and the functional class of government expenditure being increased

estimating the precision of welfare measures abstract three methods for constructing standard deviation and or confidence intervals for welfare estimates have been employed in the recreation demand literature a taylor s series approximation the bootstrap and a method proposed by krinsky and robb this paper presents the results of two sets of simulation experiments designed to examine the accuracy of these methods the first simulation examines the methods accuracy in estimating the standard deviation of welfare estimates the second simulation examines the accuracy of the methods in constructing confidence intervals

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

on measuring the benefits of lower transport costs despite large amounts invested in rural roads in developing countries little is known about their benefits this paper derives an expression for the willingness to pay for a reduction in transport costs from the canonical agricultural household model and uses it to estimate the benefits of a hypothetical road project estimation is based on novel cross sectional data collected in a small region of madagascar with enormous yet plausibly exogenous variation in transport cost a road that essentially eliminated transport costs in the study area would boost the incomes of the remotest households those facing transport costs of about usd 75 ton by nearly half mostly by raising non farm earnings this benefit estimate is contrasted to one based on a hedonic approach

the welfare effects of environmental taxation on a green market where consumers emit a pollutant this paper examines the welfare impact of emission taxes and subsidies in a green market where consumers emit a pollutant through their usage of products produced by duopolists for this purpose we employ a discrete continuous model including both consumer choice and usage of an environmentally differentiated product in a utility consistent framework the findings indicate that an emission tax is always welfare dominant over a subsidy on consumer purchases of the clean product because of its contribution to a reduction in environmental damage it does this by both inducing firms to improve the environmental qualities of their products and by constraining consumer usage of these products

competition and cooperation in corporate governance the effects of labor institutions on blockholder effectiveness in 23 european countries we provide an analysis of the costs and benefits of blockholding in europe where it is a dominant but certainly not universal corporate governance strategy for shareholders of publicly listed firms we find that the effectiveness of blockholding is conditioned by the specific labor institutions that distinguish european countries from the rest of the world and that these institutional effects involve both competition and cooperation between blockholders and collective labor interests we also find that relational blockholders are better able to cope with or benefit from these institutional effects than arm s length blockholders empirically we use advanced meta analytic methods on a total sample of 748 569 firm year observations derived from 162 studies covering 23 european countries

aid supplies over time addressing heterogeneity trends and dynamics summary what determines how much foreign aid donors provide existing answers to this question point to a complex range of influences however the tasks of distinguishing between long and short run factors as well as differences between donors have not been adequately addressed taking advantage of data spanning nearly 50 years this paper uses panel cointegration techniques to consider these issues the analysis provides clear evidence for heterogeneity both between donors and over time bandwagon effects and a growing influence of security considerations in aid provision domestic macroeconomic shocks have a moderate but delayed effect on aid disbursements

exact consumer s surplus and deadweight loss consumer s surplus is a widely used tool in applied welfare economics both economic theorists and cost benefit analysis often use consumer s surplus despite its somewhat dubious reputation the basic idea is to evaluate the value to a consumer or his willingness to pay for a change in price of a good from say pricep to pricep because price changes affect consumer welfare an evaluation of this effect is often a key input to public policy decisions yet consumer s surplus is probably the most controversial of widely used economic concepts both paul samuelson and ian little conclude that the economics profession would be better off without it it is my feeling of the situation that substantial agreement exists on the correct quantities to be measured the amount the consumer would pay or would need to be paid to be just as well off after the price change as he was before the price change the quantities correspond to john hicks compensating variation measures an alternative measure which takes ex post price change utility as the basis of comparison is hicks equivalent variation the controversy arises in the measurement of these quantities the usual measurement procedure is to use the area to the left of the marshallian market demand curve between two price levels jules dupuit originated this measure of welfare change and alfred marshall and hicks derived appropriate conditions for its use the primary condition for the area to the left of the demand curve to correspond to the compensating variation is to have constant marginal utility of income marshall gave this condition and if it holds the same quantity will be derived as the area to the left of the compensated hicksian demand curve this area to the left of the compensated demand curve is exactly what the compensating variation and equivalent variation measure thus the constant marginal utility of income is a sufficient condition for marshallian consumer s surplus to be equal to hicks consumer s surplus in this case arnold harberger s plea to use the welfare triangle as one half times the product of the price change times the quantity change to measure deadweight loss corresponds to the correct theoretical amount of welfare change in a recent paper robert willig derives bounds for the percentage difference between the correct measure of either the compensating or equivalent variation and the marshallian measure derived form the market demand curve his bounds which depend on the income elasticity of demand for the single good in the region of price change being considered as well as the proportion of the consumer s income spent on the good demonstrate that the marshallian consumer s surplus is often a good approximation to hicks consumer s surplus the fact that the proportion of the consumer s income spent matters as well as the income elasticity was first pointed out by harold hotelling willig contends that the approximation error will be less than the errors involved in estimating the demand curve thus he hopes to remove the need for apology that applied economists often need to give to theorists who remark on the inappropriateness of using marshallian consumer s surplus to measure welfare change however in this paper i show that for the case primarily considered by willig of a single price change which is also the situation in which consumer s surplus is often used in applied work no approximation is necessary professor of economics massachusetts institute of technology and research associate national bureau of economic research i would like to thank peter diamond erwin diewert daniel mcfadden robert merton robert solow hal varian joel yellin and the referees for help and comments research support from the national science foundation is acknowledged the reason that we still have two rather than one of samuelson s six measures of consumer s surplus arises from an index number problem of the correct basis for the welfare comparison i will give both measures but plan to concentrate on the compensating variation

the hedonic travel cost model a view from the trenches accessible to them consequently it is reasonable to expect that economic models of these decisions will recognize the role of recreation sites characteristics for individual demands and that they will allow for the possibility that the individual s optimal choices may not involve interior solutions in all the available recreation sites in response to these expectations the recent literature has seen a number of innovations in recreation demand models one of these models is based on a fundamen

welfare measurement in the household production framework the household production approach to consumer behavior developed from the work of gary becker william gorman and kelvin lancaster has considerable descriptive appeal in modelling the decisions of households the approach derives from the observation that households frequently purchase market goods that do not yield utility directly but are combined to produce commodity service flows which the household values thus observed behavior is determined by household production technology as well as by tastes the advantage of this distinction is that we can pose reasonable hypotheses about characteristics of technology though we rarely possess useful a priori information regarding tastes the putative advantages of the household production approach are questioned on empirical and conceptual grounds by robert pollak and michael wachter 1975 they show that jointness in production or nonconstant returns to scale cause implicit commodity prices to depend on both tastes and technology raising serious econometric difficulties in the estimation of commodity demand functions in addition since commodity prices become functions of the commodity bundle consumed the analogy to traditional demand theory breaks down joint production occurs when a good enters several production processes simultaneously or equivalently when a good in one production process also enters directly into the individual s utility function the most common example is time which provides the context for all production processes and is often associated with the production of several commodities simultaneously since joint production in the household is likely to be pervasive the critique by pollak and wachter cannot be ignored in response to the comment by william barnett pollak and wachter 1977 suggest dispensing with the notion of commodity prices and treating the demand for commodities as a function of goods prices this approach confounds tastes and technology but it eliminates the troublesome concept of commodity prices as parameters when in fact they are likely to be endogenous in this paper we show that results from positive analysis such as the critique by pollak and wachter have implications for the use of the household production framework for welfare analysis the household production function approach has had considerable appeal for measuring welfare effects of public actions in the environmental and natural resource areas gardner brown john charbonneau and michael hay elizabeth wilman yet traditional approaches to welfare measurement are frequently inapplicable we argue that welfare measurement in this framework is complicated by the difficulties of unravelling tastes and technology we extend pollak and wachter s results by demonstrating that marshallian demand functions for commodities cannot be uniquely defined thus marshallian functions cannot be used to derive exact compensated functions in the manner of jerry hausman and of george mckenzie and i f pearce nor can compensating and equivalent variation measures be bounded by marshallian consumer s surplus estimates following robert willig in fact duality results that normally allow us to move between marshallian and hicksian functions are not assistant and associate professors respectively department of agricultural and resource economics university of maryland college park md 20742 this paper is scientific article no a3404 contribution no 6476 of the maryland agricultural experiment station we wish to thank darrell hueth james opaluch v kerry smith and elizabeth wilman for comments on an earlier draft

what s the use welfare estimates from revealed preference models when weak complementarity does not hold abstract in this paper we consider the theoretical and empirical ramifications of welfare measurement in revealed preference models when weak complementarity does not hold in the context of a kuhn tucker model of recreation demand we show that while it is possible to estimate preferences that do not appear to exhibit weak complementarity the calculation of welfare measurements from these models requires a cardinal interpretation of preferences that cannot be tested furthermore we reiterate the under appreciated fact that even traditional use value estimates require a cardinal restriction on preferences that while often intuitive also cannot be tested we demonstrate empirically that the choice of restrictions can have significant ramifications as use value estimates can vary based on the assumed preference structure

valuing product attributes using single market data a comparison of hedonic and discrete choice approaches this paper compares via simulation the perfor mance of the multinomial logit and hedonic models in esti mating consumer preferences for product attributes we as cribe preferences over the attributes of houses to a population of consumers and by having them bid for a set of houses calculate equilibrium prices the resulting data are used to estimate the two models we find that the gradient of a linear box cox hedonic price function estimates marginal attribute bids at least as well as a linear logit model although the difference between the two is small when some variables are not observed or are replaced by proxies the logit model however outperforms the he donic model in valuing non marginal attribute changes this is true when the researcher knows the true form of consumers utility functions and when the utility function must be approx irnated

evaluating the performance of alternative municipal water tariff designs quantifying the tradeoffs between equity economic efficiency and cost recovery the design of municipal water tariffs requires balancing multiple criteria such as financial self sufficiency for the service provider equity among customers and economic efficiency for society a modeling framework is developed for analyzing how alternative municipal water tariff designs affect these three criteria it is then applied to a hypothetical community in which a municipal water utility provides metered piped water and wastewater services to 5 000 households we analyze how the shift from a uniform volumetric tariff to different increasing block tariff ibt designs affects households water use and water bills and how these changes in turn affect measures of equity and economic efficiency for two different financial self sufficiency targets we calculate how changes in assumptions about 1 the correlation between household income and water use and 2 households response to average or marginal prices affect the tariffs performance in terms of these three criteria the results show that ibts perform poorly in terms of targeting subsidies to low income households regardless of the magnitude of financial subsidies that a utility receives from high level government when cost recovery is low the distribution of subsidies under ibts is even worse if the correlation between water use and household income is high ibts introduce price distortions that induce economic efficiency losses but we show that these welfare losses are relatively small especially when households respond to average prices

the effects of government spending on deforestation due to agricultural land expansion and co2 related emissions this paper examines the effect of changes in government spending level and composition on deforestation due to agricultural land expansion and related carbon dioxide emissions our theoretical model shows an unintended consequence from increased government spending and widening social safety nets in developing countries where agricultural land expansion significantly affects forest cover there is an increase in deforestation and carbon dioxide emissions from land use change our empirical tests show that an increase in total government spending significantly increases forest land clearing for agricultural production in the short run leading to more carbon dioxide emissions however there is no long run statistically significant effect on the steady state forest cover and carbon dioxide emissions

employment protection and industry innovation we examine the impact of the strictness of employment protection legislation epl on innovation intensity to this purpose we use a panel of annual data from organisation for economic co operation and development countries and analyze the variation of innovation intensity within country between industries our estimates indicate that stricter epl led to significantly lower innovation intensity in industries with higher job layoff propensity our findings are robust to additional industry covariates and other labor market institutions that may affect innovation performance and industry job layoff propensity

the benefits of in kind government programs abstract in this paper i present a methodology to calculate the benefits of in kind programs such as public housing which restrict consumption of some goods to the levels offered by the government most previous studies begin with an a priori specification of the direct utility function i begin with the ordinary demand function and then integrate demand to recover the indirect utility function and the expenditure function i argue that this approach gives additional flexibility in choosing a functional form which best describes the data i then use this methodology to estimate the benefits of the u s government s section 8 housing program

work arrangements and firm innovation is there any relationship this study investigates the relationship between labour market flexibility proxied by the proportion of workers with different contractual arrangements and other indicators of flexible work relations and firms innovative ability as measured by the percentage of new products in total sales on the one hand more flexibility e g a higher labour turnover might be favourable to a firm s innovation potential aside from having potential wage savings a larger inflow of new personnel may enrich the pool of firm innovative ideas on the other hand higher work flexibility may also have some drawbacks a permanently high turnover rate may diminish social cohesion and trust and increase the probability of opportunistic behaviour results suggest that internal flexibility is positively associated with innovation for both high tech and low tech firms especially for high tech firms however greater external flexibility might hinder innovation copyright oxford university press

should governments stop subsidies to private goods evidence from rural latin america abstract this paper empirically documents the effects of subsidizing private goods to the detriment of the government s supply of public goods we use a new data set from the rural sector in fifteen latin american countries over the period 1985 2001 collected using a methodology that allows us to separate government subsidies to private goods from expenditures in the provision of public goods the econometric evidence shows that the government s decision to subsidize either private or public goods has dramatic consequences for economic development reducing the share of subsidies to private goods or equivalently increasing the share of public goods in the government s budget has ceteris paribus a large and significant positive impact on rural per capita income reduces certain undesirable environmental effects associated with output expansion and contributes to poverty reduction

why has europe become environmentally cleaner decomposing the roles of fiscal trade and environmental policies this paper examines the role of fiscal policy trade and energy taxes on environmental quality in europe using disaggregated data at the monitoring station level for the 12 richest european countries spanning the period from 1995 to 2008 our estimations show that fiscal policies and energy taxes are important determinants of pollution through various mechanisms we find that increasing the share of fiscal spending in gdp and shifting the emphasis towards spending in public goods and against non social subsidies significantly lower the concentrations of sulfur dioxide and ozone but not nitrogen dioxide at the same time energy taxes reduce nitrogen dioxide concentrations but have no effect on ozone and sulfur dioxide finally trade openness has a direct effect on sulfur dioxide but no effect on nitrogen dioxide or ozone our estimates account for time varying unobserved heterogeneity

the effect of government expenditure on the environment an empirical investigation abstract this paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980 2000 we estimate both the direct and indirect effects of government spending on pollution the indirect effect in particular operates through the impact of government spending on income and the subsequent effect of the income level on pollution to take into account the dynamic nature and the potential endogeneity in the relationships examined appropriate econometric methods are used for so2 government spending is estimated to have a negative direct impact on per capita emissions while the direct effect is insignificant on co2 pollution the indirect effect on so2 is negative for low income levels and becomes positive as income increases while it remains negative for co2 for the most part of the sample range the resultant total effects follow the patterns of the indirect effects which dominate their respective direct ones for each pollutant policy implications from the results vary depending on the income level of the considered countries

markets and the measurement of value consumer s surplus and the hicksian measures of compensating and equivalent variation have a long history in empirical economic analysis however at both the theoretical and the empirical level economists psychologists and public choice theorists have not been able to reach a significant consensus regarding the usefulness of these measures economic theorists have only recently dissected the differences which exist between alternative welfare measures in a systematic and transparent fashion in willig 1976 hausman 1981 and takayama 1984 the role of income in determining the correct theoretical measurements of compensating and equivalent variations was exposed during this same period of time theoretical results obtained by the psychologists kahneman and tversky 1979 indicated that the fundamental structure of preferences upon which the theoretical economic results are based is flawed the so called prospect theory of decision developed by these authors indicated that measured of welfare based upon payment will differ from measures of welfare based upon compensation because of the fact that individuals will value losses at a greater marginal rate than gains this difference was then predicted to dominate any income effect important in the economist s model finally this period recorded the emergence of many demand revealing processes which provide individuals with appropriate incentives to accurately reveal their preferences as summarized in coursey and schulze 1986 one interpretation of the literature on incentive compatibility suggests a set of well defined guidelines for improving both the accuracy and validity of compensating and equivalent variation measures these differences in professional preferences regarding what is important in improving the accuracy of economic welfare measurements led john

welfare losses due to market power hicksian versus marshallian measurement this paper warns against the use of marshallian welfare loss in applied analysis of market power we show how to compute the hicksian deadweight loss from an ordinary demand then from an experiment using real data on twenty one sectors of the french food industry we find that the marshallian deadweight loss poorly approximates the exact hicksian measure hence it is advisable to use the latter in applied welfare analysis copyright 2001 oxford university press

employment protection and labor productivity abstract current theoretical predictions of how employment protection affects firm productivity are ambiguous in this paper i study the effect of employment protection rules on labor productivity using swedish register data a reform of employment protection rules in 2001 enabled small firms with fewer than eleven employees to exempt two workers from the seniority rules i treat this reform as a natural experiment my results indicate that increased labor market flexibility increases labor productivity this increase is explained by total factor productivity and capital intensity rather than the educational level of workers

estimating recreation preferences using hedonic travel cost and random utility models over the last decade several authors have questioned the validity of the hedonic travel cost model arguing instead that the random utility model is a superior method for valuing recrea tional site attributes this paper demonstrates that the two methods emanate from a similar utility theoretic framework yet in practice these methods differ in the assumptions made in their appli cation constraining the underlying utility functions to be consistent both models are applied to the valuation of recreational site attributes in the southeastern united states the way in which each method estimates preferences for site attributes is shown to depend critically on the method and the functional form of the underlying utility function micro economic theory began as an attempt to describe predict and value the demand and supply of consumption goods quality was largely ignored in initial theoretical treatises goods were assumed to be homogeneous over the last two decades however economists have started to address quality within the theory of demand environmental economists have extended the theory further to value the quality of recreational sites an important component of land management two distinct approaches for incorporating quality into recreational analyses have emerged the hedonic travel cost method htc and the discrete choice random utility methods rum the hedonic method views site attributes as though they were individual goods which are bundled together in a single purchase the random utility model treats quality as an index which is estimated by examining a discrete choice of alternative sites facing a consumer because the mathematical derivations for the hedonic rosen 1974 and random utility models mcfadden 1978 are quite different many practitioners do not recognize that both models are based on a common utility theoretic foundation in the first section of this paper we show how the hedonic and random utility methods are consistent with the same utility framework

thirty years of agricultural growth in brazil crop performance regional profile and recent policy review the postwar economic growth of brazil has received much attention in specialized and general literature on development structural change associated with rapid and sustained industrialization with strong backward linkages into intermediate capital goods sectors has been the focus of much of this work the costs benefits and distortions growing out of this secular process of economic growth have been documented highlighting the unusual performance of the brazilian economy among the middle income developing countries finally the important shift in policy regimes from import substitution in the 1950s to export substitution beginning in the late 1960s has been analyzed adding a rich base of data and results with which to evaluate the brazilian performance and test various hypotheses concerning the impact of selected policy parameters on efficiency growth and distribution 2 however until recently less attention has been devoted to a review of the performance of the agricultural sector within this scenario of rapid change and growth 3 this becomes important in interpreting trends in income distribution in the 1970s this article is directed toward filling this gap in part through reviewing the empirical record on the aggregate and regional performances of output area and yield of the cropproducing sector of brazilian agriculture over the 30 year period 195080 this is possible through the extensive time series on crop output in metric tons area in hectares and physical yields generated by the annual crop reporting series of the brazilian institute of geography and statistics fibge a series that accounts for 98 of all crop output in brazil during this period

the political economy of policies for smallholder agriculture summary as the experience of the 20th century has shown implementing policies that increase agricultural productivity among smallholders is a particularly promising strategy to achieve pro poor growth however history also reveals major political challenges to adopting this strategy the paper compares the experience of asian countries that were able to launch a smallholder based green revolution with the experience of african countries that are still struggling with this goal it then reviews the political economy literature to identify the factors that account for these divergent experiences finally the paper develops a conceptual framework to guide empirical research to close the knowledge gaps identified by the review

job security provisions and employment european countries have enacted various job security provisions over the last 30 years employers are required to pay workers on separation or to give advance notice of termination in anything less than a perfectly functioning market there are effects of the provisions on employment incumbents are more likely to retain their jobs but new workers are less likely to be hired an examination of the european data suggests that severance pay requirements reduce employment

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

on the gains of committing to inefficient production lobbying and low land productivity in latin america abstract we present a new explanation and empirical evidence showing that rural subsidies to large farmers tend to be associated with low land productivity and excessive deforestation we develop a lobbying model where wealthy farmers trade bribes or political contributions to government politicians in exchange for subsidies farmers are able to tilt the terms of the bargaining game with policy makers in their favor by pre committing to an inefficient choice of semi fixed inputs government proneness to accept political contributions or bribes and its willingness to provide subsidies cause farmers to adopt inefficient modes of production as a mechanism to capture such subsidies our predictions are consistent with stylized facts on land use in latin america and suggest that subsidy schemes have been counterproductive distorting and constraining development and triggering excessive depletion of natural resources we validate some of the predictions of the model through econometric analyses using a new data set for nine countries in latin america

the taxation of drivers and the choice of car fuel type in this paper the choice of the car fuel type is studied in the dutch situation three types are important gasoline diesel and lpg with 80 of the cars using gasoline incentives for using diesel or lpg are provided by the tax system that implies higher fixed cost but lower variable cost for users of these fuel types we start by studying fuel type choice on the basis of a logit model and move on to estimate demand functions for kilometres driven for social purposes while correcting for the possible selectivity bias we find that diesel and lpg are in general regarded as inferior alternatives but that monetary incentives are sufficiently strong to overcome this hurdle for drivers with a large demand for kilometres we also find that there are significant effects of the lower variable cost for diesel and lpg drivers on their demand for kilometres the conclusions are confirmed by estimation of a structural model in which fuel type choice and demand for kilometres are consistently explained on the basis of one set of preferences and unobserved heterogeneity is taken into account

temporary jobs institutions and wage inequality within education groups in central eastern europe summary in this paper we investigate the drivers of wage inequality within education groups in central eastern european countries by employing eu silc microdata before 2007 and after 2012 the crisis our main focus is on the variability of temporary permanent workers wage gap and on the role of institutions labor market deregulation union density and wage coordination in shaping the gap across education groups and along the wage distribution results obtained by means of ols and quantile regression methods confirm that holding a temporary position corresponds to a statistically significant negative wage gap with respect to permanent jobs especially for low paid jobs and tertiary educated workers the impact of institutional settings on the wage gap varies remarkably across education groups and wage levels and strongly depends on the macroeconomic conditions labor market deregulation and weaker minimum wage provisions reduce the wage gap this could be related to the fact the these institutional features reduce the duality on the labor market triggering a downward convergence of permanent wages toward the lowest level of the temporary employed especially in the context of labor reallocation and declining wages typical of recession stronger wage setting institutions on the contrary seem to reinforce duality in the labor market although to different extents depending on the group of workers and on the part of the wage distribution concerned

the effect of common sources of regression error on benefit estimates discussions of the sources of error in recreation demand analysis are common in the existing literature the most traditional line of thought e g gum and martin considers the error component in predicting the individual s recreation behavior to arise from unmeasured socioeconomic factors others e g hanemann attribute at least some of this error to fundamental randomness in human behavior applied statisticians e g hiett and worrall on the other hand suggest that recall of annual number of recreational trips i e the quantity demanded is subject to substantial error still others e g brown et al have argued that recall of explanatory variables such as travel expenses contains error despite the discussion of potential error sources there is no work which relates the sources of error in the demand relationship with benefit measurement 1 of practical importance in recreational demand estimation is whether error assumptions have an influence on welfare measures since it is for public policy decision purposes that recreational demand estimation is usually undertaken will the estimated consumer surplus derived from demand analysis be independent of the assumed source of the error in the regression the purpose of this paper is to explore how the assumptions about sources of error influence estimates of recreation benefits a discussion of the various sources of error in de

approximating compensated income from ordinary demand functions abstract this paper proposes a re versible s econd or der t aylor resort approximation to compensated income from ordinary demand functions resort yields the malmquist vartia m v algorithm as a first order case using the slutsky equation resort obtains the substitution matrix and checks it for symmetry and negative semi definiteness to validate compensated income this validation procedure is an improvement over m v

combining farrell frontier and hedonic travel cost models for valuing estuarine quality a 1992 survey of tennessee anglers was used to determine who is fishing and how often the species they fish for and how anglers perceive the regulatory structure the results are based on telephone interviews with 450 active licensed an glers nearly 81 of the anglers visited a tennessee reservoir in 1992 while 41 fished warm water streams 28 farm ponds and 22 trout streams over 60 pre ferred separate regulations for reservoirs active reservoir fishermen were more likely to support individual regulations the participants were evenly split on whether a proposed regulation which has public support should be imposed even if the manage ment agency does not feel the fishery would benefit eighty percent of the anglers indicated that existing fishing regulations were not complicated proc annu conf southeast assoc fish and wildl agencies 47 767 774 proper administration of fishery resources requires management authorities to have knowledge of the angler population served by the management agency specifically authorities should be aware of the type and intensity of angler activi ties and understand angler preferences concerning existing and proposed management alternatives to the degree that certain types of fishermen are less likely to support management policies authorities should target educational pro grams specifically at non supportiv e anglers to gain greater public support for biologically viable management strategies this study uses data gathered from a survey of tennessee anglers to deter mine who is fishing and how often the species they are targeting and how anglers perceive the regulatory structure we report the demographic factors of anglers which exhibit statistically significant relationships to angler support for the current

expenditure function estimates of the efficiency and distributive impact of indirect taxes in the united kingdom abstract this paper uses the expenditure function to consider the efficiency and distributional impact of indirect taxes in the united kingdom estimates of the parameters of the linear expenditure system of demand equations are employed to measure the compensating variation and equivalent variation costs of taxes on households in different income groups in addition distributional weights are used to consider the overall impact of different taxes and tax changes on social welfare finally we consider other types of demand system estimates which might be used in this kind of exercise

a consistent semiparametric estimation of the consumer surplus distribution abstract in this paper we examine the consequences of demand function heterogeneity for the estimation of the consumer surplus in particular we show that given a linear demand function with random coefficients one can consistently estimate the consumer surplus distribution without making parametric assumptions about the coefficient distribution the approach is illustrated using data on gasoline consumption

linear demand functions in theory and practice abstract integrability conditions for an incomplete system of linear demand functions are considered the parameter restrictions consistent with integrability are identified and the structure of the conditional preference map is obtained it is found that the conditional preferences for a set of linear demand functions are either quadratic or leontief from a translated origin welfare analysis with linear demand models is also considered

a pareto improving minimum wage this paper shows that a graduated minimum wage in contrast to a constant minimum wage can provide a strict pareto improvement over what can be achieved with an optimal income tax the reason is that a graduated minimum wage requires high productivity workers to work more to earn the same income as low productivity workers which makes it more difficult for the former to mimic the latter in effect a graduated minimum wage allows the low productivity workers to benefit from second degree price discrimination which increases their income

environmental food taxes and inequalities simulation of a meat tax in sweden abstract this paper investigates the distributional effect of an environmental tax on meat in sweden if such a tax was to be introduced welfare effects are measured as compensation variation cv for multiple price changes where hicksian cross price elasticities household expenditures and price changes are included in the calculations results show that taxes on meat are almost neutral over households when expenditures on meat are used as welfare indicators and regressive if income is used this can be explained by the households similar shares of total expenditures on meat the households with the smallest income levels need to be compensated with 904 sek per person and year equivalent to euro 86 6 per year in the year 2009 exchange rate to feel that utility is not lowered if taxes on meat are introduced and the households with the highest income levels need to be compensated with 1141 sek euro 109 3 per person and year for the year 2009 these compensations correspond to 0 74 and 0 78 of total expenditures for the low and high income group respectively when instead comparing the compensation with income levels the effects correspond to 0 99 for the households with the smallest income levels and to 0 51 for the households with the largest income

institutions and firms adjustments measuring the impact of courts delays on job flows and productivity abstractnot only is labor market rigidity the result of legislative provisions but it is determined by the institutional framework at large we argue that courts delays in settling labor disputes affect the strictness of employment protection legislation by increasing the expected firing costs we exploit the variation in the length of labor trials across italian judicial districts and the fact that the italian legislation regarding firing prescribes different firing regimes for firms above the 15 employee threshold and provide evidence on the impact of courts delays on job reallocation and firms productivity we show that in judicial districts with longer trials the rate of job turnover is significantly lower this occurs through lower rates of job destruction and to a lesser extent job creation we also find a detrimental impact of courts delays on the labor productivity of firms above the 15 employee threshold the effect is stronger in sectors with higher flexibility requirements

welfare improving employment protection this paper derives new results on the welfare effects of employment protection using data from 17 oecd countries we show that there exists an inverse u shape relationship between employment protection and economic growth using a simple theoretical model with non contractible specific investments we show that over some range increasing employment protection does indeed raise welfare we also show that the optimal level of employment protection depends on other labour market features such as the bargaining power of workers and the existence of wage rigidities like the minimum wage

returns to investment in education a global update the author updates compilations of rate of return estimates to investment in education published since 1985 and discusses methodological issues surrounding those estimates some key patterns among the three main levels of education primary education continues to exhibit the highest social profitability in all world regions private returns are considerably higher than social returns because of the public subsidization of education the degree of public subsidy increases with the level of education which is regressive social and private returns at all levels generally decline by the level of a country s per capita income overall the returns to female education are higher than those to male education but at individual levels of education the pattern is more mixed the returns to the academic secondary school track are higher than the vocational track since unit cost of vocational education is much higher and the returns for those who work in the private competitive sector of the economy are higher than in the public noncompetitive sector and the returns in the self employment unregulated sector of the economy are higher than in the dependent employment sector controversies in the literature are discussed in the light of the new evidence the undisputable and universal positive correlation between education and earnings can be interpreted in many ways the causation issue on whether education really affects earnings can be answered only with experimental data generated by randomly exposing different people to various amounts of education given the fact that moral and pragmatic considerations prevent the generation of such pure data researchers have to make do with indirect inferences or natural experiments some have been attempted the author looks at the research on overeducation or surplus schooling the conclusions reinforce earlier patterns they confirm that primary education continues to be the number one investment priority in developing countries they also show that educating females is marginally more profitable than educating males that the academic secondary school curriculum is a better investment than the technical vocational tract and that the returns to education obey the same rules as investment in conventional capital that is they decline as investment is expanded
