measuring market power in bilateral oligopoly the wholesale market for beef econometric methods for assessing the degree of market power typically rely on a maintained hypothesis of price taking behavior on one side of the market or the other in the analysis of bilateral oligopoly however one would like to leave open the question of whether buyers or sellers or both behave competitively while allowing for the possible exercise of market power on either side in this paper we address the problem of measuring market power in bilateral oligopoly this requires that we first distinguish among three candidate equilibrium concepts bilateral price taking seller price taking and buyer price taking choosing among them comes down to a test of nonnested nonlinear simultaneous equation models our application to the u s wholesale market for beef characterized by high degrees of concentration among both sellers beef packers and buyers primarily retail grocery chains reveals seller price taking among the three candidates to be the most consistent with the data in particular the hypothesis of price taking conduct on both sides of the market can be rejected this is a conclusion that would not have been reached had we considered monopoly conduct by sellers as the only alternative to perfect competition

women as policy makers evidence from a randomized policy experiment in india this paper uses political reservations for women in india to study the impact of women s leadership on policy decisions since the mid 1990 s one third of village council head positions in india have been randomly reserved for a woman in these councils only women could be elected to the position of head village councils are responsible for the provision of many local public goods in rural areas using a dataset we collected on 265 village councils in west bengal and rajasthan we compare the type of public goods provided in reserved and unreserved village councils we show that the reservation of a council seat affects the types of public goods provided specifically leaders invest more in infrastructure that is directly relevant to the needs of their own genders

tourism demand forecasting models choice of appropriate variable to represent tourists cost of living abstract price is generally regarded as a major determinant of demand tourism has two price elements the cost of travel to the destination and the cost of living for tourists in the destination previous studies where econometric forecasting models have been developed for international tourism demand usually take the consumer price index in a country to be a proxy for the cost of tourism in that country owing to lack of appropriate data this article attempts to evaluate the performance of proxy variables compared with a specific tourists cost of living variable within the context of tourism demand forecasting models

why political reservations many countries are amending their political systems to set aside positions to groups such as women and racial or religious minorities that are perceived as being disadvantaged using evidence from india this article assesses the case for these reservations jel h4 o15 several countries have introduced procedures either explicit quotas or forms of gerrymandering to ensure political representation of disadvantaged groups such as women or ethnic minorities in 2001 quotas for women in parliaments were in force in more than 30 countries in india seats are reserved for historically disadvantaged groups scheduled castes or sc and scheduled tribes or st in federal or state legislative assemblies and for both historically disadvantaged groups and women at all levels of the panchayat system the system of decentralized decision making on the basis of evidence accumulated about the indian experience this paper reviews the case for reservation

effects of horizontal consolidation under bilateral imperfect competition between processors and retailers this article considers bilateral imperfect competition between processors and retailers to estimate the trade off between market power and cost efficiency the model is based on pricing rules from a firm s profit maximization and nests both oligopoly and oligopsony models an empirical analysis for us beef processors and retailers suggests that processors tend to exercise oligopsony market power in procuring cattle but they are unlikely to exercise market power on retailers when retailers and processors are considered as one integrated sector efficiency effects from the increased concentration in the us beef packing industry are slightly larger than market power effects when processors market power is considered separately from retailers market power the difference between cost saving and market power effects becomes greater the cost elasticity estimate 0 99 indicates that a further merger would result in little economies of scale in the future therefore although we find that efficiency effect

a micro analysis of business travel demand this study tests two hypothesis 1 that tax deductibility and the dual benefit nature of goods on the business pleasure borderline increases the demand for business travel and 2 that this dual benefit decreases price elasticity the study uses expenditure microdata and contrasts the behaviour of business travellers and pleasure travellers both groups are assumed to have indentical tastes but the expenditure behaviour of business travellers is modified by the role of the business trip as a factor of production the linear expenditure system les allocation model is applied to expenditures on individual goods at a particular tourist destination business travellers are shown to have higher expenditures than pleasure travellers for food lodging and local transportation minimum quantities estimated by the les are also higher for business travellers uncompensated price elasticities of business travellers are significantly smaller than that of pleasure travellers for local transportation clothing a

on the optimality of cost plus non uniform pricing in vertical control problems abstract this paper argues that cost plus non linear contracts are the general solution of the vertical control problem where there are multiple upstream firms one downstream firm and no uncertainty two part tariffs are only optimal if upstream firms have linear costs cost plus contracts are also shown to be a solution of the bilateral monopoly problem

subsidy and tuition policies in public higher education i introduction the much discussed and widely debated recent conditions in public higher education include expanding enrollments flat if not declining public appropriations per resident student and rapid increases in tuition rates 1 to many observers tuition policy in public higher education appears be explained as an attempt to set tuition at whatever level is necessary to compensate for shortfalls between public appropriations and instructional expenditures ehrenberg 2006 asserts that public higher education has been buffeted by a perfect storm in which state appropriations to public higher education institutions have failed to keep pace with per student expenditures in private higher education because of economic recession the priorities placed on alternative uses of state tax revenues such as elementary and secondary education medicaid welfare and criminal justice and efforts to reduce income and sales tax rates a considerable empirical literature examines the relationship between tuition in public higher education and state appropriations koshal and koshal 2000 identify a negative relationship between tuition and state appropriation a study of college costs and prices which is conducted by cunningham et al 2001 identifies an inverse association between tuition rates and annual budget appropriations but finds little evidence of a link between tuition and expenditures on instruction lowry 2001 treats state appropriations as exogenous in a resident tuition equation and discovers a significant negative relationship between state funding and tuition rizzo 2005 finds that increases in tuition are linked to declines in future levels of state funding which hints at a dynamic association rizzo and ehrenberg 2004 in one of the more extensive examination of the topic treat real state appropriations per student as an exogenous variable in their resident tuition equation and find that schools that receive higher state appropriations per student charge lower tuition though the elasticity is far from unity acknowledging the economic and demographic conditions of public higher education and the empirical literature linking appropriations and tuition raises a number of questions what activities are legislatures supporting when they allocate public funds to higher education what are the implied responsibilities for subsidizing residents versus nonresidents how are resident and nonresident tuition rates determined and what are the relationships among tuition rates resident and nonresident enrollments and state appropriations to higher education in particular there appears to be the need to develop a better understanding of the decision processes that determine both the public subsidy and the setting of tuition rates a goal of this article is to develop a conceptual framework for that process there is a widely held notion that residents should pay a lower tuition than nonresidents and as a result of a resident subsidy they do so in nearly all public universities one rationale for favorable treatment is that residents and their parents pay state taxes another claim which receives some support by groen 2004 is that residents are likely to remain in the state after graduation and thus contribute future tax revenues although the public subsidy to higher education is justified for these and many other economic development reasons some argue that the higher education subsidy is simply a payoff to special interest groups who influence legislatures and governors friedman 1968 and goldin and katz 1998 provide a general discussion of the objectives of subsidized higher education for whatever reasons resident students continue to receive a substantial publicfinanced subsidy while nonresidents pay close to full cost there are two basic arrangements for determining tuition rates in higher education 1 institutions determine tuition rates under the direction of an independent governing board and 2 state legislatures who are governed by statues and budget policies make tuition decisions

bad loans to good friends money politics and the developmental state in south korea why has the literature on asian development not addressed the issue of money politics in south korea how can we reconcile the view of an efficient developmental state in south korea before 1997 with reports of massive corruption and inefficiency in that same country in 1998 and 1999 politics is central to the answer in this study i make two arguments first money politics was extensive in south korea both during and after the high growth era second political not economic considerations dominated policymaking this study explains both past and present and compares the patterns of money politics in the early post independence era with those that arose after the democratic transition in 1987 while during the park era a balance of power between businessmen and politicians kept corruption from spinning out of control the transition to democracy altered the basic business state relationship allowing business to exert greater influence over policy decisions the political hypothesis advanced in this study suggests a new direction for our research about the developmental state

the impact of employment quotas on the economic lives of disadvantaged minorities in india abstract india has the world s biggest and arguably most aggressive employment based affirmative action policy for minorities this paper exploits the institutional features of a federally mandated employment quota policy to examine its causal impact on the economic lives of the two distinct minority groups scheduled castes and scheduled tribes my main finding is that a 1 percentage point increase in the employment quota for scheduled castes increases the likelihood of obtaining a salaried job by 0 6 percentage points for male scheduled caste members residing in the rural sector the employment quota policy has no impact for scheduled tribes contrary to popular notion i do not find evidence of elite capture among the scheduled castes the impact is concentrated among members who have completed less than secondary education consistent with the employment results i find that the policy improved the well being of scheduled castes members in rural areas who have completed less than secondary education finally the impact of the employment quota policy varies by state characteristics

breaking the caste barrier intergenerational mobility in india we contrast the intergenerational mobility rates of the historically disadvantaged scheduled castes and tribes sc st in india with the rest of the workforce in terms of their education attainment occupation choices and wages using survey data from successive rounds of the national sample survey between 1983 and 2005 we find that intergenerational education and income mobility rates of sc sts have converged to non sc st levels during this period moreover sc sts have matched non sc sts in occupation mobility rates we conclude that the last 20 years of structural changes in india have coincided with a breaking down of caste based barriers to socioeconomic mobility

income and the substitution pattern between domestic and international tourism demand this article analyses the role of income in the decision of participating in the tourism demand within 1 year the tourists who are participating can travel to domestic destinations only abroad destinations only or to both of them such a substitution pattern is modelled using a bivariate probit model the analysis is carried out to the regional level using a survey conducted in 15 european eu 15 countries in addition to the traditional socioeconomic variables the analysis adds new variables to the outbound tourism demand modelling such as the attributes of the place of residence the results show that tourism demand is income elastic however there are marked differences in the income elasticities of the probabilities of travelling domestically or abroad above certain income threshold the substitution pattern between destinations takes part the probability of travelling domestically only remains constant whereas the probability of travelling abroad keeps growing additionally the article prov

affirmative action in education evidence from engineering college admissions in india abstract this paper examines an affirmative action program for lower caste groups in engineering colleges in india we study both the targeting properties of the program and its implications for labor market outcomes we find that affirmative action successfully targets the financially disadvantaged the upper caste applicants that are displaced by affirmative action come from a richer economic background than the lower caste applicants that are displacing them targeting by caste however may lead to the exclusion of other disadvantaged groups for example caste based targeting reduces the overall number of females entering engineering colleges we find that despite poor entrance exam scores lower caste entrants obtain a positive return to admission our estimates however also suggest that these gains may come at an absolute cost because the income losses experienced by displaced upper caste applicants are larger than the income gains experienced by displacing lower caste students limited sample sizes in our preferred econometric specifications however prevent us from drawing strong conclusions from these labor market findings

holiday taking and income this paper is the first attempt to estimate the determinants of holiday taking across several countries to accomplish this a two stage estimation procedure is employed which enables incongruous income categories to be transformed into a single income variable it is found that in the mid 1980s there was a substantial similarity in the holiday taking behaviour of europeans the large national differences in holiday participation are explained by differences in income and demographic factors a remarkable regularity in the responsiveness of the probability of holiday taking to marginal changes in income is found

can mandated political representation increase policy influence for disadvantaged minorities theory and evidence from india accountable governments often fail to reflect the interests of disadvantaged minorities this paper exploits the institutional features of political reservation as practiced in indian states to examine the role of mandated political representation in providing disadvantaged groups influence over policy making ifind that political reservation has increased transfers to groups which benefit from the mandate this finding also suggests that complete policy commitment may be absent in democracies as is found in this case jel d72 d78 hl 1 h50

evaluating a simple method for estimating black white gaps in median wages racial differences in wage rates are important measures of economic inequality among races because for almost all individuals labor income constitutes the most important component of lifetime income as a consequence the prices at which individuals may sell their time provide vital infornation about the distribution of welfare and economic success however we only observe prices when market transactions occur and thus we only observe wage rates for individuals who are employed since the wages of employed workers are not randomly sampled from the distribution of potential wages it is difficult to draw inferences concerning racial gaps in potential wages from data on observed wage rates richard butler and james heckman 1977 raised this issue in the context of assessing the impact of government policies on racial income inequality charles brown 1984 james smith and finis welch 1989 and amitabh chandra 2000 also examine the extent of racial differences in participation rates and the impact of these differences on measures of racial wage and income gaps this topic remains salient in part because employment rates among working age black males remain significantly below corresponding rates for whites neal and johnson 1996 estimated racial gaps in median wages among men by imputing wages of zero for all men in a particular crosssection who report that they have not worked at all during the survey period under a specific assumption concerning the distribution of missing wages this procedure yields consistent estimates of the black white gap in median wages conditional on observed characteristics below we spell out this assumption and use panel data to investigate the extent to which it may be violated in cross section wage analyses our results suggest that imputing wages of zero for unemployed individuals may provide a reasonable way to estimate median wage regressions among men

affirmative action and labor markets affirmative action remains controversial the controversy extends from the original antidiscrimination legislation and its interpretation to estimates of affirmative action s effect on the labor market this paper provides a progress report on our recent efforts at detecting the effects of affirmative action on minority wages and employment although we find a substantial increase in wages for black men and black women over our sample period the timing of these wage changes is surprising most of the wage gains came prior to 1974 before the establishment of an effective monitoring structure for affirmative action indeed when the powers of the eeoc and ofcc are greatest the wage effects for young blacks are somewhat perverse using eeo 1 reports we find a major shift in black employment toward firms most vulnerable to the monitoring and potential sanctions of the affirmative action programs as with wages the shift in minority employment came prior to the expansion of the powers and budgets of the ee

will affirmative action policies eliminate negative stereotypes a key question concerning affirmative action is whether the labor market gains it brings to minorities can continue without it becoming a permanent fixture in the labor market the authors argue that this depends on how the policy affects employers beliefs about the productivity of minority workers they study the joint determination of employer beliefs and worker productivity in a model of statistical discrimination in job assignments the authors prove that even when identifiable groups are equally endowed ex ante affirmative action can bring about a situation in which employers correctly perceive the groups to be unequally productive ex post copyright 1993 by american economic association

understanding tourists economizing strategies during the global economic crisis abstract this paper explores how tourists from 165 regions of eu 27 countries cut back their tourism expenditure during the global economic crisis in 2009 cutbacks in tourism expenditure are divided into two mutually related decisions firstly whether or not the tourists decided to cut back on tourism expenditure because of the crisis and second which of six options they employed as their cut back strategy fewer holidays reduced length of stay cheaper means of transport cheaper accommodation travel closer to home or change the period of travel the econometric model used to address these kinds of simultaneous decisions is an adaptation of the heckman model within a generalized structural equations modelling approach this methodology controls for sample selection bias and correlations between equations this paper highlights patterns in cutback decisions that are associated with the socioeconomic characteristics of the household and the climate in the country of origin

consumer behaviour in greece an application of the almost ideal demand system this paper estimates the almost ideal demand system on greek data for the period 1960 1986 for seven commodity groups the results conform with earlier research findings that the homogeneity and symmetry restrictions of demand theory are broadly inconsistent with the data the imposition of the restrictions leads to substantial changes in the estimated elasticities in both the static and dynamic specifications the introduction of habit effects with lagged consumption supported statistically by the data led to plausible results leaving however the problem of rejection of homogeneity and symmetry intact

tests of restrictions in large demand systems abstract this paper compares some asymptotic tests of linear restrictions using exact results and monte carlo methods in systems which contain the same regressors in each equation it is found that under a variety of conditions a statistic suggested by deaton provides a better approximation to the true distribution in small sample situations than the wald likelihood ratio or lagrange multiplier tests

determining market power exertion between buyers and sellers empirical techniques commonly used in industrial organization to measure market power exertion typically assume imperfectly competitive behaviour by firms on only one side of the market firms on the other side are assumed to be perfectly competitive in this paper we extend traditional neio methods by developing a method to estimate market power exertion when firms on both sides have potential market power using monte carlo simulations we find that the model correctly estimates market power exercised by firms on either or both sides of a market and also correctly estimates firms technology parameters when applied to the us leaf tobacco market findings indicate that cigarette manufacturers exert some monopsony power in purchasing leaf tobacco while producers organized as a cartel exhibit no countervailing monopoly market power copyright 2000 john wiley sons ltd

black white earnings ratios since the civil rights act of 1964 the importance of labor market dropouts published median earnings of wage and salary workers by race and sex are based on distributions that exclude those without earnings and those not employed as wage and salary workers at the time of the survey it has been argued that the changing importance of these exclusions rather than any improvement in the distribution of offered wages for blacks accounts for the apparent increase in black white relative median earnings this paper presents a new method for correcting the published medians for such censoring the apparent improvement in relative earnings is reduced but not eliminated by the correction

the effects of itq management on fishermen s welfare when the processing sector is imperfectly competitive in this paper we use a general model of imperfect competition to predict welfare changes within an open access fishery after it transitions to individual transferable quota itq management although related research has explored the effects of market power in the harvesting sector on itq performance none has considered the implications of an imperfectly competitive processing sector addressing this question we find that although fishermen should expect to gain from itqs under perfect competition they may suffer welfare losses if the processing sector is imperfectly competitive

pricing solutions to the bilateral monopoly problem under uncertainty that uniform pricing solutions to the bilateral monopoly problem are sub optimal is well known see for example scherer 19 and waterson 22 over the years there has been considerable debate in the literature as to what constitutes a correct solution to the static bilateral monopoly problem under certainty this is usefully reviewed in machlup and taber 10 and blair kaserman and romano 3 as the latter paper points out the principal conclusion of this debate is that the solution must involve

a cure for discrimination affirmative action and the case of california s proposition 209 proposition 209 enacted in california in 1996 and made effective the following year ended state affirmative action programs not only in education but also for public employment and government contracting this paper uses cps data and triple difference techniques to take advantage of the natural experiment presented by this change in state law to gauge the labor market impacts of ending affirmative action programs employment among women and minorities dropped sharply a change that was nearly completely explained by a decline in participation rather than by increases in unemployment this decline suggests that either affirmative action programs in california had been inefficient or that they failed to create lasting change in prejudicial attitudes

climate in the region of origin and destination choice in outbound tourism demand abstract this paper describes the relationship between regional climate in the home area and the choice of taking holidays in the region of origin or abroad this decision is simultaneously estimated with a bivariate probit model the study combines the socioeconomic characteristics of european households with information on the region of residence such as climate which is defined according to a new annualized climate index the estimated probabilities are analysed using gis and nonparametric techniques the results of modelling support the hypothesis that the climate in the region of residence is a strong determinant of holiday destination choice they show that residents in regions with better climate indices have a higher probability of travelling domestically and a lower probability of travelling abroad

the effect of court ordered hiring quotas on the composition and quality of police arguably the most aggressive armative action program ever implemented in the united states was a series of court ordered racial hiring quotas imposed on municipal police departments my best estimate of the eect of court ordered armative action on workforce composition is a 14

an econometric study of tourism demand the aids model of us and european tourism in mediterranean countries the almost ideal demand system aids model was used to estimate tourism expenditure allocation by us and west european countries among a range of mediterranean destinations the approach has the advantage of an explicit basis in consumer expenditure theory and by modelling the changes in the budget shares of expenditure among destinations provides new information relative to that provided by the traditional single equation approach the estimated model was econometrically satisfactory although symmetry and homogeneity were rejected in line with the findings of past studies of consumer demand the expenditure elasticities demonstrated considerable differences in tourism demand preferences between origin countries and between traditional and newly developing destinations the own and cross price elasticities indicated the importance of effective prices in determining the allocation of expenditure among destinations

a pedagogical treatment of bilateral monopoly most economists are familiar with the concept of bilateral monopoly an upstream monopolist sells its output to a single downstream buyer that may also be a monopolist in its output market the theory of bilateral monopoly has a rich history that can be traced to the writings of cournot 10 and menger 31 over the 150 or so years that the problem has been under consideration however economists have offered a variety of solutions ranging from a completely determinate intermediate good price and output to a completely indeterminate solution within a specified range interestingly this historical divergence of opinion concerning the correct outcome under bilateral monopoly still persists a clear consensus has not yet emerged surprisingly this lack of unanimity exists despite the fact that bowley 5 provided the theoretically correct solution in 1928 2 even more surprising however is the apparent popularity of the incorrect solution a recent survey of the population of intermediate microeconomic texts on the authors bookshelves revealed that over 80 percent of the current treatments of this topic are in error 3 table i presents the results of that survey those authors who present a correct analysis of bilateral monopoly recognize that optimality requires joint profit maximization this leads them to the correct conclusion regarding the determinate quantity of the intermediate product exchanged of the five treatments we have classified
