the consequences of legal minimum wages in honduras summary minimum wage policies are implemented in most developing countries so understanding their consequences is critical to determine their effectiveness this paper quantifies the labor market and poverty effects of honduran minimum wages from 2005 to 2012 using 13 household surveys as repeated cross sections i estimate the net effects of minimum wage hikes using variation from annual reforms to multiple minimum wages a 60 increase and changes in the number of minimum wage categories evidence shows that employers are partially complying with minimum wage laws and respond to hikes by increasing their level of non compliance higher minimum wages reduce covered formal employment and increase uncovered informal employment formal sector wages increase but greater labor supply in the informal sector leads to a negative net effect on wages this last result is often empirically ambiguous although consistent with the dual sector minimum wage model i find no evidence that minimum wages reduce extreme or moderate poverty

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

renewable energy expansion in the chilean power market a dynamic general equilibrium modeling approach to determine co2 emission baselines abstract over the last decade a high dependency on carbon intensive fuels in the chilean power sector has led to environmental concerns particularly regarding rapid growth in co2 emissions more recently the power sector has experienced significant structural changes with a rapid expansion of renewables in the energy matrix and this trend is expected to cause significant variations in future co2 emission baseline scenarios to investigate the economy wide impact of renewable energy expansions in chile s energy mix this research based on a computable general equilibrium cge model examines different co2 emission baseline scenarios however because traditional cge modeling approaches cannot capture the impact of a sector s recent structural changes we present a step by step approach to incorporate different energy matrices from an external engineering bottom up model into the cge model the results indicate that the business as usual bau scenario in which structural changes are not considered significantly overstates expected emissions conversely considering structural changes in our cge model shows chile advancing towards its declared nationally determined contribution ndc to reduce greenhouse gas emissions furthermore the methodology implemented in the study has the advantage of being a simple integrated approach that is coherent with current modeling capacities in many developing contexts

can labor market policies reduce deaths of despair do minimum wages and the earned income tax credit eitc mitigate rising deaths of despair we leverage state variation in these policies over time to estimate event study and difference in differences models of deaths due to drug overdose suicide and alcohol related causes our causal models find no significant effects on drug or alcohol related mortality but do find significant reductions in non drug suicides a 10 percent minimum wage increase reduces non drug suicides among low educated adults by 2 7 percent and the comparable eitc figure is 3 0 percent placebo tests and event study models support our causal research design increasing both policies by 10 percent would likely prevent a combined total of more than 700 suicides each year

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

no spurious welfare gains from taxation a further argument for the equivalent variation abstract among all measures based on money metric compensation functions solely the excess burden based on the equivalent variation always correctly identifies the excess burden of a specific tax to be positive this provides a new argument for the use of the equivalent variation when measuring the welfare effects of a price change

the dual structure of incomplete demand systems integrability of incomplete demand systems is discussed the concepts of weak integrability quasi expenditure function quasi indirect utility function and quasi utility function are defined their relationships to the expenditure function indirect utility function and utility function are developed the dual structure of the quasi functions permits exact welfare analysis and reveals the conditional preference structure for the commodities of interest new results relating the uniqueness and exactness of consumer s surplus to the structure of the expenditure and indirect utility functions are obtained

transition towards a low carbon economy a computable general equilibrium analysis for poland in the transition to sustainable economic structures the european union assumes a leading role with its climate and energy package which sets ambitious greenhouse gas emission reduction targets by 2020 among eu member states poland with its heavy energy system reliance on coal is particularly worried on the pending trade offs between emission regulation and economic growth in our computable general equilibrium analysis of the eu climate and energy package we show that economic adjustment cost for poland hinge crucially on restrictions to where flexibility of emission abatement revenue recycling and technological options in the power system we conclude that more comprehensive flexibility provisions at the eu level and a diligent policy implementation at the national level could achieve the transition towards a low carbon economy at little cost thereby broadening societal support

did unilateral divorce laws raise divorce rates a reconciliation and new results application of the coase theorem to marital bargaining suggests that shifting from a consent divorce regime to no fault unilateral divorce laws should not affect divorce rates each iteration of the empirical literature examining the evolution of divorce rates across us states has yielded different conclusions about the effects of divorce law liberalization i show that these results reflect a failure to jointly consider both the political endogeneity of these divorce laws and the dynamic response of divorce rates to a shock to the political regime taking explicit account of the dynamic response of divorce rates to the policy shock i find that liberalized divorce laws caused a discernible rise in divorce rates for about a decade but that this increase was substantially reversed over the next decade that said this increase explains very little of the rise in the divorce rate over the past half century both administrative data on the flow of new divorces and measures of the stock of divorcees from the census support this conclusion these results are suggestive of spouses bargaining within marriage with an eye to their partner s divorce threat

the minimum wage in formal and informal sectors evidence from an inflation shock abstract i estimate the effect of the minimum wage on formal wages informal wages and employment in colombia i exploit an unexpected increase in the real minimum wage during 1999 my analysis combines unconditional quantile regressions with a differences in differences design i find evidence of wage responses for wages close to the minimum wage the increases are present in both the informal and formal sectors and are larger in the formal one wages around the minimum increase by around 3 percent in the formal sector for a 10 percentage points larger minimum wage incidence and by around 1 percent in the informal sector these increases are smaller than those implied by full compliance to minimum wage policy but positive for some unaffected workers this suggests employers partially comply with the minimum wage and use it as a reference i find slight negative employment effects on the informal sector but not on the formal sector the effects in the informal sector are not driven by cross sectoral effects the results suggest the minimum wage has a direct impact on the informal labor market although they may not apply to minimum wage changes in other countries or contexts or to larger minimum wage increases

exact welfare measurement for producers under uncertainty many useful results have been derived for different characterizations of uncertainty in the theory of the firm for example sandmo batra and ullah pope and kramer blair however the limited literature available on producer welfare measurement under uncertainty pope chavas and just pope and chavas just hueth and schmitz is pessimistic about the possibilities for deriving exact welfare measures from ex ante supply functions the only exception is pope and chavas who derive error bounds for the use of producer s surplus as an approximation for true welfare change that are analogous to willig s bounds for consumer s surplus as an approximation of compensating or equivalent variation however these results are presumably subject to the same shortcomings noted by hausman and amended by haveman gabay and andreoni for willig s error bounds even though compensating or equivalent variation is approximated well a poor approximation of deadweight loss may result pope chavas and just show that the ex ante supply function derived from an uncertainty model is generally not sufficient for determining true welfare change except in the special case of constant absolute risk aversion because decisions depend on the firm s wealth for nonneutral risk preferences a parameter price change induces a wealth effect in addition to an ordinary output effect thus for exact welfare measurement under price uncertainty the unobservable compensated constant expected utility supply function is needed newbery and stiglitz among others have shown that the area above an expected supply function is generally not a valid welfare measure

development of the electricity environmental policy cge model gtap e powers a case of the carbon tax in south africa abstract a new carbon price mechanism with full emission coverage is developed within the framework of a global computable general equilibrium model gtap e powers to enhance the capacity and accuracy for climate change and energy policy assessment the model developed is then used to examine the potential impacts of the carbon tax in south africa results show that incorporation of non co2 emissions in the model significantly alters the results of which the economy of south africa experiences higher costs compared to the case that only has co2 emissions when more sectors are included in the policy it also puts higher costs on the economy as higher levels of emissions are subject to the carbon tax results also show that south africa only experiences small tradeoffs from introducing the carbon tax in all scenarios that is with a tax rate of 9 15 the country is able to reduce its emission levels by 12 25 15 6 at the costs of real gdp reduction by 1 17 1 59 fossil based industrial sectors are particularly worst off while clean and renewable energy sectors strongly expand their production the results indicate that south africa is likely to move to a low carbon and sustainable economy with such a policy

modeling recreation demand in a poisson system of equations an analysis of the impact of international exchange rates we extend count data travel cost modeling by developing a utility theoretic system of semilogarithmic recreation demand equations the restrictions required to make the system utility theoretic are applied during estimation the model is applied to individual wilderness recreation trips in a system of four canadian wilderness parks the resulting demand system is used to examine the impacts of changing u s canadian currency exchange rates on participation and welfare of u s recreationists

an introduction to the wage curve en conomists and policymakers are interested in understanding the forces that determine the level of unemployment and the level of wages this paper describes an empirical discovery made with the help of international microeconometric evidence covering more than a dozen nations about a link between these two variables the connection can be portrayed on a graph with the level of unemployment on the horizontal axis and the level of wages on the vertical axis then the wage curve as shown in figure 1 is a downwardsloping locus this relationship tells us that holding others things constant if a region has a rise in unemployment in a particular year those who live there will have a fall in their wages in that year what does this curve mean how in a field where fully controlled experiments are almost impossible could there be any convincing scientific basis for this wage curve what is the relationship between the wage curve and a phillips curve other than that the curve of figure 1 looks like a phillips curve with the vertical axis mislabeled how does the wage curve fit into existing economic knowledge and is the empirical finding consistent with competitive theory this paper sketches answers to these kinds of questions the discussion draws on our book the wage curve blanchflower and oswald 1994 where the points raised here are investigated more fully it also rests upon work done by other economists whose work is listed in the paper and the bibliography

the effects of energy price technology and disaster shocks on china s energy environment economy system abstract this paper constructs a dynamic stochastic general equilibrium dsge model to analyze the effects of energy price technology and disaster shocks on china s energy environment economy 3e system it also studies stylized facts as well as co integration and error correction dynamic analyses of this system the disaster shock is modeled as a two state markov switching process the results show that both technology and energy price shocks increase the ratio of environmental investment to gdp the improvement in technology and rising energy prices helps to reduce co2 pollution and improve economic restructuring among the three kinds of shocks technology shock is the most important the robustness of the model is tested through statistical methods

on the microeconomic foundations of linear demand for differentiated products abstract this paper provides a thorough exploration of the microeconomic foundations for the multi variate linear demand function for differentiated products which is widely used in industrial organization the setting is the standard representative consumer with a quasi linear utility function a key finding is that strict concavity of the quadratic utility function is critical for the demand system to be well defined otherwise the true demand function may be quite complex multi valued non linear and income dependent we uncover failures of duality relationships between substitute products and complementary products as well as the incompatibility between high levels of complementarity and concavity the two good case emerges as a special case with strong but non robust properties a key implication is that all conclusions derived in applied economic models via the use of linear demand that does not satisfy the law of demand ought to be regarded with some suspicion

getting handcuffs on an octopus theoretical work on minimum wage policy emphasizes labor market dynamics but the resulting implications for worker mobility remain largely untested the authors show that in the teenage labor market higher minimum wage standards reduce worker flows and increase job stability furthermore they find that the employment effects of a relatively higher minimum wage vary considerably across markets with different levels of turnover and labor market tightness results help to explain the small effects of minimum wage standards on employment commonly found in the aggregate data and are consistent with labor market models that involve search frictions

evaluation of nonmarket goods recovering unconditional preferences a new approach is proposed for the evaluation of nonmarket goods starting from a complete or incomplete conditional demand system for market goods which is observable and depends on nonmarket goods this information is not sufficient to recover the underlying preference ordering of the representative consumer the central idea is to employ additional marginal willingness to pay functions for the nonmarket goods since they can be estimated either together with the demand system or in a separate step they are less arbitrary than the assumptions or hypotheses usually made if the entire system is weakly integrable the underlying ordering and appropriate welfare measures can be derived in this article i investigate the relationship between conditional and unconditional demand systems present sufficient conditions for weak integrability and demonstrate the practicability of the procedure proposed by means of three examples

non price equilibria for non marketed goods abstract as part of the resources for the future frontiers of environmental economics collection of papers we consider the problem of general equilibrium feedback effects in non price space as they relate to non market valuation our overall objective is to examine the extent to which non price equilibria arising from both simple and complex sorting behavior can be empirically modeled and the resulting differences in partial and general equilibrium welfare measures quantified after motivating the problem in general we consider the specific context of congestion in recreation demand applications which we classify as the outcome of a simple sorting equilibrium using both econometric and computable general equilibrium cge models we examine the conceptual and computational challenges associated with this class of problems and present findings on promising solution avenues we demonstrate the relevance of accounting for congestion effects in recreation demand with an application to lake visits in iowa our econometric and cge results confirm that for some plausible counterfactual scenarios substantial differences exist between partial and general equilibrium welfare estimates we conclude the paper by describing tasks that are needed to move forward research in this area

industry dynamics and the minimum wage a putty clay approach we document two new findings about the industry level response to minimum wage hikes first restaurant exit and entry both rise following a hike second there is no change in employment among continuing restaurants we develop a model of industry dynamics based on putty clay technology that is consistent with these findings in the model continuing restaurants cannot change employment and thus industry level adjustment occurs gradually through exit of labor intensive restaurants and entry of capital intensive restaurants interestingly the putty clay model matches the small estimated short run disemployment effect of the minimum wage found in other studies but produces a larger long run disemployment effect

duality theory for variable costs in joint production duality methods for incomplete systems of consumer demand equations are adapted to the dual structure of variable cost functions in joint production this allows identification of necessary and sufficient restrictions on technology and cost so that con ditional factor demands can be written as functions of input prices fixed inputs and cost these are observable when variable inputs are chosen and committed to production hence the identified restrictions allow ex ante conditional demands to be studied using observable data this class of production technologies is consistent with all von neu mann morgenstern utility functions when ex post production and or output prices are un certain

the calibration of incomplete demand systems in quantitative analysis an easily implemented and flexible calibration technique for partial demand systems is introduced combining recent developments in incomplete demand systems and a set of restrictions conditioned on the available elasticity estimates the technique accommodates various degrees of knowledge on cross price elasticities satisfies curvature restrictions and allows the recovery of an exact welfare measure for policy analysis the technique is illustrated with a partial demand system for food consumption in korea for different states of knowledge on cross price effects the consumer welfare impact of food and agricultural trade liberalization is measured

non joint technologies the hypothesis of non jointness in input quantities separate production functions is well known and it plays an important role in many areas of economics in this paper we define three additional forms of non jointness which have received little or no attention in the literature and which might be relevant for the firm as well as for the representation of the aggregate technology we characterize all forms of non jointness in terms of variable profit and joint cost functions this yields a number of restrictions which are all testable empirically the assumption that production is non joint in input quantities separate production functions inputs allocated between the different production processes plays a crucial role in many areas of economic theory we need only think of international trade theory public finance macroeconomics growth theory or traded non traded good models of international finance in fact it is safe to say that more often than not production is assumed non joint in input quantities in multiple output models little work has been done to test the empirical validity of the assumption of non jointness in input quantities samuelson 1966 studies the characterization of non joint technologies in terms of the transformation function as pointed out by hall 1973 however samuelson s results do not seem very useful for econometric work hall studies the characterization of non jointness in input quantities in terms of the joint cost function this leads to a number of restrictions which can easily be imposed or tested for and which were used in empirical work by burgess 1976 and by kohli 1981 lau 1972 1978 finally characterizes non jointness in input quantities in terms of the profit function besides non jointness in input quantities lau also examines the case of non jointness in output quantities when an input can be cracked into several outputs in this paper we define two additional cases of non jointness and we characterize them in terms of the joint cost function and the variable or normalized restricted profit function the new forms of non jointness that we define may be useful to describe technologies at the level of the firm and may be even more so at the aggregate level some may be useful concepts in other areas of economics as well such as consumer theory by distinguishing between the various forms of non jointness one obtains a number of testable restrictions on the corresponding joint cost or variable profit functions

measuring angling quality in count data models of recreational fishing a non nested test of three approaches this paper develops a methodology for investigating different specifications of angling quality in recreational demand models the methodology is used to compare three alternative specifications of the relationship between angling demand and site quality the site quality alternatives include chemical concentrations biological stress indices based on the chemicals and catch per unit effort the three alternatives are differentiated using a likelihood ratio non nested testing procedure

estimating social welfare using count data models an application to long run recreation demand under conditions of endogenous stratification and truncation this paper develops a negative binomial model of recreation demand that corrects for both truncation and endogenous stratification this approach recovers the demand associated with the general population not just the users of the site this model demonstrates the importance of the joint nature of the population s latent demand for trips and the consumer surplus associated with those trips the empirical results provide an estimate of the willingness to pay by washington state residents for hiking opportunities in the cascade mountain range these results are used to forecast total trips and willingness to pay over the next forty years copyright 1995 by mit press

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 structure of constant elasticity demand models the demand model with constant price and income elasticities has been used extensively in applied agricultural economics this paper analyzes the structure of incomplete systems of constant elasticity demand functions it is demonstrated that there is a duality theory for incomplete demand systems that is analogous to the duality theory for complete systems this theory permits the recovery of that portion of the direct and indirect preferences pertaining to the goods of interest and we can calculate exact welfare measures for changes in income and in the prices of these goods for an incomplete system of constant elasticity demands the slutsky symmetry restrictions for integrability are presented and the implied structure of the direct and indirect preferences with respect to the prices and goods of interest is derived

the effect of minimum wages on employment a factor model approach this paper resolves issues in the minimum wage employment debate by using factor model econometric methods to address concerns related to unobserved heterogeneity recent work has shown that the negative effects of minimum wages on employment found using traditional methods are sensitive to the inclusion of controls for regional heterogeneity and selection of states that experience minimum wage hikes leaving the two sides of the debate in disagreement about the appropriate approach factor model methods are an ideal solution for this disagreement as they allow for the presence of multiple unobserved common factors which can be correlated with the regressors these methods provide a more exible way of addressing concerns related to unobserved heterogeneity and are robust to critiques from either side of the debate the factor model estimators produce minimum wage employment elasticities that are much smaller than the traditional ols results and are not statistically different from zero these results hold for many specications and two datasets that have been used in the minimum wage employment literature a simulation shows that unobserved common factors can explain the different estimates seen across methodologies in the literature

compensating variation consumer s surplus and welfare the compensating variation was defined by j r hicks 1942 as the amount one would have to deduct from a person s income to make him just as well off after a change in prices and income as he had been in the initial situation if the compensating variation is positive the individual is better off under the new situation since the compensating variation furnishes a uniquely defined numerical cardinal indicator of welfare improvement it provides an implicit ranking of alternative prospective situations not only relative to the initial situation but also relative to each other in practice this appears to be how this and other tools of cost benefit analysis are actually used one is interested in knowing not only whether a particular bridge or a particular excise tax will lead to an improvement in welfare but which out of a set of alternative bridges or alternative tax systems will improve welfare the most 1 in this paper we analyze conditions under which the compensating variation can be validly used in this generalized sense these turn out to be precisely the same as conditions previously derived see our 1976 paper for the valid use of consumer s surplus as a welfare measure in our final section we analyze the problem of deriving the generalized equivalent and compensating variations either exactly or approximately from observable demand functions by means of generalizations of or alternatives to consumer s surplus

measuring recreation values with multiple destination trips traditional travel cost analysis has either ignored multiple destination trips or arbitrarily allocated trip costs across visited sites in this paper combinations of multiple destinations are treated as unique sites and incorporated into a demand system empirical demand functions for multiple destination trips that include bryce national park are estimated consumer surplus calculations for single destination and multiple destination trips are compared

supply demand and technology in a multiproduct industry texas field crops the purpose of this paper is to examine the structure of agricultural production for six texas field crops cotton grain sorghum wheat corn rice and hay which account for nearly 95 of recent field crop value specific objectives are to a test the structure of technology to determine i if output and input utilization choices for individual products are independent of production decisions about other outputs and ii if products and or inputs can be consistently aggregated b estimate a coherent set of interrelated supply functions for the six commodities and input demand functions for fertilizer and hired labor because the empirical focus of this paper is specific to one state the results will be of limited value for interpreting specific production relationships elsewhere however the problem is of common interest in production agriculture and the techniques used demonstrate an important application of dual modeling

do state minimum wages affect the incarceration rate because of historically unprecedented increases in the prison population since the late 1970s the united states has the highest incarceration rate in the world using becker s 1968 framework on crime this study investigates the causal relationship between incarceration rates and state minimum wages our identification strategy consists of a state level fixed effects model and autor and dorn s 2013 two stage least squares 2sls approach using the historical local industry structure we predict the change in employment shares of manual task intensive occupations and use those as an instrument for state minimum wages the fixed effects and 2sls estimates suggest that a one dollar increase in state minimum wage leads to approximately 12 25 fewer incarcerations per 100 000 state residents estimates of the heterogeneous impacts by race and gender indicate that the aggregate impact of state minimum wages is entirely driven by men

a cost approach to economic analysis under state contingent production uncertainty this article explores the economics of input decision under production uncertainty the article develops a methodology to specify and estimate cost minimizing input decisions under a state contingent technology the analysis is applied to time series data on u s agriculture it finds strong empirical evidence that expected output alone does not provide an appropriate representation of production uncertainty the results provide empirical support for an output cubical technology this indicates that an ex post analysis of stochastic technology appears appropriate the analysis also provides evidence that the cost of facing production risk has declined in u s agriculture over the last few decades copyright 2008 oxford university press

non competitive market behaviour in the international coking coal market in this paper a primal dual programming model of international coking coal trade is constructed to test for non competitive market behaviour world trade in 1996 is simulated under perfect competition and various non competitive market structures statistical tests are used to compare simulated trade flows with actual data assuming cournot nash behaviour an all consumer oligopsony market structure is preferred to alternative models under an all consumer oligopsony world coking coal prices and trade are lower than under perfect competition under an oligopsonistic structure welfare gains from productivity increases in australian coal mines might largely accrue to coal buyers

application of computable general equilibrium cge to climate change mitigation policy a systematic review abstract with the growing literature related to climate change mitigation measures and policy interventions a systematic review of the application of computable general equilibrium cge model is inevitable therefore this article aims to characterise the relevant studies define a comparative framework to identify the current state of the art and the gaps in applied general equilibrium models firstly the systematic review found a total of 301 research articles from scopus and web of science databases and finally analysed 154 articles based on inclusion and exclusion criteria from 67 refereed journals the review analysis found that application of cge model is very vital in addressing climate change mitigation issues at the national regional and global levels however china attracted the most substantial research interests followed by the usa india and australia among others which are in line with their share of greenhouse gas emissions in the world most of the research themes focus on the carbon tax emission reduction target emission trading renewable energy energy efficiency and carbon capture and storage as primary drivers of low carbon economy nevertheless there is a trend of employing more static cge model compared to the dynamic cge although application of the latter has a limitation of providing right inputs to the macroeconomic policy finally research directions and gaps envision other complementary models such as dynamic stochastic general equilibrium dsge and agent based model abm for proper policy interventions

on measuring the value of a nonmarket good using market data we use line integral theory to lay out in a more general theoretical framework the conditions under which it is possible to measure with market data the welfare effects of a change in a nonmarket good we present in detail a numerical method of measuring the value of nonmarket goods using market data under either weak neutrality or weak complementarity our numerical method is more flexible than the existing analytical method because it can be used with any well behaved marshallian demand function and can be used even when the willig condition does not hold

estimation of multicrop production functions this paper considers whether separability or nonjointness is the better approach for attaining tractability for multicrop production function estimation characteristics of agricultural production associated with allocated inputs physical constraints and output determination imply sufficient nonjointness for estimation whereas separability is less plausible the paper also addresses estimation of production functions with allocated inputs where allocations are not observed and demonstrates a proposed approach by way of example

spatially uneven development and low carbon transitions insights from urban and regional planning the ageing of existing energy system infrastructure the threat of climate change and uncertainty in the movement of energy prices have resulted in a widespread agreement on the need for a transition to a low carbon energy system yet the nature of this transition i e what when how and where and its socio economic outcomes at different scales are not well understood the interdependence of the energy sector and economic growth has been mostly studied at the national level via some general equilibrium or econometric models whilst sub national studies at community or urban levels mostly focus on the governance of transitions hence we suggest that a regional perspective to energy policy and research promises to integrate these two approaches by providing a more robust and comprehensive understanding of the implications of low carbon transitions as well as contributing to the development of more effective policies by building on recent ideas on geographical aspects of energy transitions this article offers insights on the changing relationship between the spatial organisation of economic activities and energy systems and identifies tools and methods from urban and regional planning to help with the delivery of efficient and equitable policy outcomes

tax uncertainty and business activity abstract we investigate the extent to which uncertainties about tax policies affect business activities we develop a statewide tax uncertainty measure tu measure and show that it captures state corporate tax uncertainty by comparing adjacent counties across state borders we show that increasing tax uncertainty by one standard deviation a 30 increase in the tu measure leads to a 0 17 point per year decrease in the growth rate of establishments over two years the result holds after conducting a variety of robustness checks and is not likely to be driven by general state policy uncertainties

effects of the minimum wage on employment dynamics the voluminous literature on minimum wages offers little consensus on the extent to which a wage floor impacts employment we argue that the minimum wage will impact employment over time through changes in growth rather than an immediate drop in relative employment levels we show that commonly used specifications in this literature especially those that include state specific time trends will not accurately capture these effects using three separate state panels of administrative employment data we find that the minimum wage reduces job growth over a period of several years this finding is supported using several empirical specifications

the minimum wage and the great recession evidence of effects on the employment and income trajectories of low skilled workers abstract we estimate the minimum wage s effects on low skilled individuals employment and income trajectories following the great recession our approach exploits two dimensions of the data we analyze first we compare individuals in states that were fully bound by the 2007 to 2009 increases in the federal minimum wage to individuals in states that were not second we use variation in the minimum wage s bite across skill groups to separate our samples into target and within state control groups using the 2008 panel of the survey of income and program participation we find that binding minimum wage increases had significant negative effects on the employment and income growth of targeted workers although there are important limitations to our research designs our estimates are robust to adopting a range of alternative strategies to construct our analysis samples and to account for variation in the great recession s underlying severity across states in aggregate our estimates suggest that this period s minimum wage increases reduced aggregate employment rates by at least half of a percentage point in states that were bound by the federal minimum wage increases because our estimates are large relative to what one would infer from past research we emphasize the relevance of the historical episode we analyze

the costs of compliance a cge assessment of canada s policy options under the kyoto protocol canada has committed itself under the kyoto protocol to reduce greenhouse gas emissions between 2008 and 2012 on average by six per cent from the base 1990 level as of 2009 however canada s greenhouse gas emissions are far above its 1990 level which calls for stringent short term policy measures if canada is to meet its legally binding commitment this paper uses a multi region multi commodity static general equilibrium model to quantify the economic impacts of alternative compliance strategies for canada in the context of climate policies undertaken by other kyoto parties the numerical results confirm fears by canadian policymakers of substantial economic adjustment costs should canada fulfill its kyoto commitments solely through domestic action however a rigorous use of the project based cdm on top of international emissions trading could allow canada to live up to its international climate policy commitment at politically much more tolerable costs

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

welfare and distribution effects of water pricing policies in this paper distribution and welfare effects of changes in block price systems are evaluated a method is discussed to determine for a marshallian demand function equivalent variation in case of a block price system the method is applied to compare for the metropolitan region of sao paulo alternative pricing policies on the basis of their demand welfare and distribution effects of changing water prices results show that there is a trade off between average welfare and income distribution a pro poor price system may result in lower average welfare than a flat price system but in higher individual welfare for the poor moreover there is a trade off between revenues for the water company and income distribution even though pro poor price systems may not be as good for average welfare as flat price systems their direct effects on poverty are important introducing pro poor price systems however may have financial consequences for the water companies

alternative models of recreational off highway vehicle site demand a controversial recreation activity is off highway vehicle use off highway vehicle use is controversial because it is incompatible with most other activities and is extremely hard on natural eco systems this study estimates utility theoretic incomplete demand systems for four off highway vehicle sites since two sets of restrictions are equally consistent with utility theory both are imposed and the best fitting restrictions are identified using voung s non nested testing scheme the demand system is modeled using both poisson and negative binomial ii distributions data are provided by a survey conducted at four recreational off highway vehicle ohv sites in western north carolina

the eu 20 20 2020 targets an overview of the emf22 assessment three computable general equilibrium models are used to estimate the economic implications of a stylized version of eu climate policy if implemented at the lowest possible cost the 20 emissions reduction would lead to a welfare loss of 0 5 2 0 by 2020 second best policies increase costs a policy with two carbon prices one for the ets one for the non ets could increase costs by up to 50 a policy with 28 carbon prices one for the ets one each for each member state could increase costs by another 40 the renewables standard could raise the costs of emissions reduction by 90 overall the inefficiencies in policy lead to a cost that is 100 125 too high the models differ greatly in the detail of their results the ets non ets split may have a negligible impact on welfare while the renewables standard may even improve welfare the models agree however that the distortions introduced by total eu package imply a substantial welfare loss over and above the costs needed to meet the climate target the marginal total and excess costs reported here are notably higher than those in the impact assessment of the european commission

cost functions under production uncertainty we characterize the cost functions which would be consistent with expected utility maximization when production is uncertain it is not generally possible assuming risk aversion to use only expected output as the constraint in a cost minimization problem in some leading cases cost functions consistent with expected utility maximization are particularly useful because they are devoid of risk preferences

further results on willingness to pay for nonmarket goods abstract some implications of substitution relationships between private and public goods for measuring the value of changes in nonmarket goods such as environmental quality are explored if a market good is hicks neutral to quality for some price vector the total value of discrete changes in quality consisting of both use and nonuse value can be measured from empirical demand coefficients a plausible motivation for neutrality is developed in the contexts of specifying incomplete demand systems for weak complements to quality and measuring nonuse value when the consumption of weak complements is held at zero previous results on bounding marginal willingness to pay for nonmarket goods are also strengthened

a reconsideration of the sugar sweetened beverage tax in a household production model abstract we study the impact of a hypothetical tax on sugar sweetened beverages ssbs on the u s households nutrients purchase welfare change and health benefit differently from the traditional approach food at home fah is here defined as a home good instead of a market good and consumers demands derived under the assumption that households maximize utility subject to both a money and a time constraint the model is estimated by using an incomplete approximate exact affine stone index easi demand system on a data set built by merging the u s consumer expenditure and time use surveys results show that a ssb tax would be much more effective in decreasing household nutrients purchase than it would appear by estimating a model neglecting time costs in home food production due to a lesser compensation of calories from increasing fah consumption a tax induced 38 increase in ssb price is predicted to decrease the per capita energy purchase by 41 kcal day

minimum wage policy with optimal taxes and unemployment abstract using a search model i derive a formula that links the welfare gains from the minimum wage to its effect on low skilled labor force participation and employment this formula shows that the minimum wage is welfare improving if pushing the low skilled labor market tightness downwards brings it closer to its efficient level i estimate the causal effect of the minimum wage on low skilled labor force participation and employment using federal and state minimum wage variation i discuss the policy implications of my estimates when viewed through the lens of the marginal welfare gain formula

empirical specification requirements for two constraint models of recreation choice two constraint models are common in recreation demand analysis because of the important role time can play in consumer choices two versions of roy s identity hold for these models and imply coefficient restrictions on empirical demand functions the two constraint restrictions are fully observable and can be expressed in a form analogous to the slutsky hicks equations in single constraint consumer models empirical specifications that use full prices and full budgets can be consistent with the two constraint models when the marginal value of time is either exogenous or endogenous but models with full prices and money income alone are not copyright 2001 oxford university press

revisiting the minimum wage employment debate throwing out the baby with the bathwater we revisit the minimum wage employment debate which is as old as the department of labor in particular we assess new studies claiming that the standard panel data approach used in much of the new minimum wage research is flawed because it fails to account for spatial heterogeneity these new studies use research designs intended to control for this heterogeneity and conclude that minimum wages in the united states have not reduced employment we explore the ability of these research designs to isolate reliable identifying information and test the untested assumptions in this new research about the construction of better control groups our evidence points to serious problems with these research designs we conclude that the evidence still shows that minimum wages pose a tradeoff of higher wages for some against job losses for others and that policymakers need to bear this tradeoff in mind when making decisions about increasing the minimum wage

integrability of incomplete systems of demand functions the problem of integrating back from an incomplete set of demand functions to a utility function is considered conditions permitting local integrability are analogous to those which arise in local integrability theorems for complete systems but the analysis of the global integrability of incomplete systems differs markedly from that of complete systems

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

the effect of minimum wages on low wage jobs we estimate the eect of minimum wages on low wage jobs using 138 prominent state level minimum wage changes between 1979 and 2016 in the u s using a dierence in dierences approach we first estimate the eect of the minimum wage increase on employment changes by wage bins throughout the hourly wage distribution we then focus on the bottom part of the wage distribution and compare the number of excess jobs paying at or slightly above the new minimum wage to the missing jobs paying below it to infer the employment eect we find that the overall number of low wage jobs remained essentially unchanged over the five years following the increase at the same time the direct eect of the minimum wage on average earnings was amplified by modest wage spillovers at the bottom of the wage distribution our estimates by detailed demographic groups show that the lack of job loss is not explained by labor labor substitution at the bottom of the wage distribution we also find no evidence of disemployment when we consider higher levels of minimum wages however we do find some evidence of reduced employment in tradable sectors we also show how decomposing the overall employment eect by wage bins allows a transparent way of assessing the plausibility of estimates

can minimum wages cause a big push evidence from indonesia big push models suggest that local product demand can create multiple labor market equilibria one featuring high wages formalization and high demand and one with low wages informality and low demand i demonstrate that minimum wages may coordinate development at the high wage equilibrium using data from 1990s indonesia where minimum wages increased in a varied way i develop a difference in spatial differences estimator which weakens the common trend assumption of difference in differences estimation reveals strong trends in support of a big push formal employment increases and informal employment decreases in response to the minimum wage local product demand also increases and this formalization occurs only in the non tradable industrializable industries suggested by the model while employment in tradable and non industrializable industries also conforms to model predictions

match bias in wage gap estimates due to earnings imputation about 30 of workers in the current population survey have earnings imputed wage gap estimates are biased toward zero when the attribute being studied e g union status is not a criterion used to match donors to nonrespondents an expression for match bias is derived in which attenuation equals the sum of match error rates attenuation can be approximated by the proportion with imputed earnings union wage gap estimates with match bias removed are presented for 1973 2001 estimates for recent years are biased downward 5 percentage points bias in gap estimates accompanying other non match criteria public sector industry etc is examined

minimum wage shocks employment flows and labor market frictions we provide the first estimates of the effects of minimum wages on employment flows in the u s labor market identifying the impact using policy discontinuities at state borders we find that minimum wages have a sizable negative effect on employment flows but not stocks separations and accessions fall among affected workers we interpret our findings using a job ladder model in which minimum wage increases can reduce job to job transitions we find that a standard calibration of the model generates predicted relative magnitudes of the employment stock and flow elasticities that are very close to our reduced form estimates

world crude oil and natural gas a demand and supply model abstract this paper examines world markets for crude oil and natural gas over the period 1918 1999 it analyzes the time series properties of output and prices and estimates demand and supply elasticities during 1918 1973 and 1973 1999 oil and gas prices were stable during the first period they became volatile afterwards reflecting deep changes in the market structure following the oil shock in 1973 demand price elasticities were too low however demand income elasticities were high supply price elasticities were also too low the elasticity estimates help to explain the market power of the oil producers and price volatility in response to shocks and corroborate elasticity estimates in energy studies
