testing for asymmetric information in insurance markets the first goal of this paper is to provide a simple and general test of the presence of asymmetric information in contractual relationships within a competitive context we also argue that insurance data are particularly well suited to such empirical investigations to illustrate this claim we use data on contracts and accidents to investigate the extent of asymmetric information in the french market for automobile insurance using various parametric and nonparametric methods we find no evidence for the presence of asymmetric information in this market

flexible demand systems with serially correlated errors fat and oil consumption in the united states a flexible demand system proposed by lewbel is used to estimate u s fat and oil demand from 1950 to 1986 results suggest that the lewbel model outperforms the translog and aids and that correction for serial correlation is important findings also suggest that price and income effects together with increasing public health concerns primarily determine u s fat and oil demand

the effect of income and food programs on dietary quality a seemingly unrelated regression analysis with error components this article employs new food guide pyramid servings data to measure how food intake is affected by income and two food programs the analysis uses a maximum likelihood estimator that combines the seemingly unrelated regression and one way error component models to account for two types of intrahousehold correlations participation in the food stamp program is associated with higher intake of meats added sugars and total fats participation in the special supplemental nutrition program for women infants and children is associated with lower intake of added sugars

effects of food prices and consumer income on nutrient availability economic factors such as food prices and consumer income affect food choices with consequences for the availability of nutrients a new research model is developed to estimate how the availability of 28 nutrients would change as consumers alter their food purchases in response to changes in food prices and income through the interdependent food demand relationships

stigler becker versus myers briggs why preference based explanations are scientifically meaningful and empirically important abstract economists typically object to preference based explanations of human behavior differences in preferences explain everything and therefore nothing but this argument is only correct assuming that no empirical evidence exists to discipline preference based explanations in fact over the past decade personality psychologists have produced a robust collection of stylized facts about human preferences while preferences are empirically quite stable they are far from identical and have proven predictive power for economically interesting variables the empirical challenge for future research is to jointly estimate the impact of preferences and constraints to obtain unbiased measures of their relative importance

industrial determinants of anti dumping in brazil protection competition and performance an analysis with binary dependent variable and panel data abstract this article investigates how sectorial characteristics determine the probability of industries receiving an anti dumping ad duty delving into the economic literature on the political economy of protection market competition and trade reform in brazil by focusing on when the ad was granted the article concentrates on the objective economic motivations for an industry to claim protection and which are instrumental to the decision of the trade defense authority the empirical strategy involves a panel of 93 industrial sectors from 1996 to 2007 to create four groups of explanatory variables collective action competition economic performance factors of production trade coefficients reflecting their structural characteristics market competition economic performance and political mobilization the econometric specifications apply binary dependent variable models logit with cluster robust and population averaged error correction the results show that structure of trade imports volume and tariffs economic performance productivity and investments and factor content labor and natural resources influence the probability of the ad political economy characteristics captured by interactive terms are also influential in determining the measure

does antidumping use contribute to trade liberalization in developing countries some supporters of antidumping have argued that this procedure serves as a kind of safety valve for protectionist pressure in this paper we investigate whether there is empirical evidence that the use of antidumping actions has contributed to ongoing tariff reductions over the period 1988 to 2004 in a sample of 23 developing countries some of which have become aggressive users of antidumping in recent years the evidence is not supportive of the safety valve argument for these countries instead evidence suggests that past use of antidumping may have led to less rather than more trade liberalization

entrepreneurship social mobility and income redistribution in south india development economists have been preoccupied with the problem of increasing the size of the gnp pie to the relative neglect of its distribution despite the recent disenchantment with the viewpoint that all classes share in the benefits of industrial growth empirical data on the distribution of income business opportunity and economic power are in short supply many of the studies on entrepreneurship and economic development when they are not apologetics for ruthless capitalist exploitation as paul baran suggests extol the achievements of the capitalist entrepreneur without examining class origins and monopoly advantage joseph schumpeter sees entrepreneurs irrespective of class origin as heroic figures with the dream and will to found a private kingdom to conquer adversity to achieve success for its own sake and to experience the joy of creation for gustav papanek 1967 the private entrepreneur who is frugal diligent far sighted remarkably able and willing to take political risks is in large part responsible for the success of pakistan in achieving rapid industrialization

maintaining and testing separability in demand systems we derive a general elasticity representation of the necessary and sufficient conditions for direct weak separability of the utility function parametric restrictions required to implement the separability conditions are presented for three common demand systems the almost ideal translog and rotterdam our empirical application uses the rotterdam model to test a few separable structures within a complete u s demand system emphasizing food commodities results based on size corrected likelihood ratio tests provide support for commonly used separability assumptions about food and meat demand

nesting the aids and translog demand systems this paper shows that there exists a relatively simple demand model that is consistent with utility maximization and has nested within it both the almost ideal demand system and translog models this model is exactly aggregated then estimated using aggregate u s demand data the results are used to test the relative adequacy of the almost ideal demand system and translog models copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the producer welfare effects of trade liberalization when goods are perishable and habit forming the case of asparagus asparagus is a perishable highly seasonal crop we find that out of season imports of asparagus caused habit formation that increased demand in the u s growing seasons we find that habit effects offset about 64 of the welfare losses to u s asparagus producers from increased mexican imports under nafta and all of the u s producer welfare losses from increased peruvian imports under the andean trade preference act we estimate that the u s producer welfare losses from nafta are less than the annualized value of market loss assistance provided them in the 2008 farm bill jel classifications d12 f130 q17 q18

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

macro economic determinants of antidumping a comparative analysis of developed and developing countries abstract this study examines how macro factors influence the use of antidumping in developed and developing countries a panel data analysis of 99 countries over 1980 2000 reinforces the view that the primary jurisdiction for the antidumping law is really more political than economic furthermore it suggests that once the wto is fully enforced the use of antidumping will spread among developing countries not only due to greater liberalization pressures but also as many countries would like to create an antidumping ability so as to counter its use against them this may reverse the trade gains that liberalization may ensure to them this paper thus calls for the granting of the special and differential treatment to developing countries in this provision finally based on its findings the paper argues that future negotiations should be directed toward revising safeguard rules and replacing antidumping by this new clause

genetic variation in financial decision making individuals differ in how they construct their investment portfolios yet empirical models of portfolio risk typically account only for a small portion of the cross sectional variance this paper asks whether genetic variation can explain some of these individual differences following a major pension reform swedish adults had to form a portfolio from a large menu of funds we match data on these investment decisions with the swedish twin registry and find that approximately 25 of individual variation in portfolio risk is due to genetic variation we also find that these results extend to several other aspects of financial decision making

aggregation flexible forms and estimation of food consumption parameters reply grouping schemes commodity aggregation and the choice of functional specification significantly influence the results of empirical demand studies this article assesses the importance of these factors for estimating aggregate food consumption parameters a flexible food demand model that nests alternative specifications is estimated using u s data foods are aggregated based on a new grouping scheme adopted from the dietary guidelines for americans nutrient intake elasticities with respect to food prices and expenditure are calculated the influence of socioeconomic variables on consumption and nutrient intake is analyzed price income and demographic effects are found to be highly significant our findings are invariant to the choice of functional form

the political economy of administered protection trade restrictions are hardly ever voted directly by congress though the threat of direct congressional action is frequently present pressure for protection is usually applied through the major instruments for the administrative regulation of imports the antidumping and countervailing duty procedures and the escape clause mechanism in this paper we will examine these instruments for the administrative regulation of imports the form of the paper is not novel a theory of how these mechanisms work is developed then operational implications of this theory are deduced and tested over the record of countervailing duty antidumping and escape clause cases decided from 1975 through 1979 this is the period over which the trade act of 1974 was in force because the nature of these mechanisms is relatively unfamiliar a relatively large amount of institutional information is provided

rules or politics an empirical analysis of itc anti dumping decisions this research analyzes the international trade commission s anti dumping decisions from 1980 to 1986 the results suggest that commissioners use criteria consistent with the instructions set forth in u s legislation the analysis also indicates that political variables help predict commissioner decisions petitions involving senate oversight committee members constituencies may be systematically favored in the process evidence of possible bias toward less developed country exports is presented as well the methodology also yields estimates of commissioner specific fixed effects

an examination of personality in occupational outcomes antagonistic managers careless workers and extraverted salespeople abstractthis article investigates the role of personality in the sorting of individuals between a number of occupations allowing for an extensive array of conditioning variables the focus is an examination of the relationship between occupational outcomes and personality using the five factor model we estimate a multinomial logit model using a panel data set from the household income and labour dynamics in australia hilda survey human capital variables are found to exhibit strong credentialism effects and there is evidence for some small dynasty hysteresis personality effects are found to be significant relatively large and persistent across all occupations the personality effects are strong enough to rival that of various education credentials these personality effects include but are not limited to managers being less agreeable and more antagonistic labourers being less conscientiousness and salespeople being more extraverted

cumulation and itc decision making the sum of the parts is greater than the whole in 1984 congress amended the antidumping and countervailing duty laws man dating that the international trade commission itc cumulate imports across countries when determining injury we estimate that cumulation increases the probability of an affirmative injury determination by 20 to 30 percent and has changed the itc s decision from negative to affirmative for about one third of cumulated cases we also show that the protective effect of cumulation increases as the number of countries involved increases holding import market share constant that is cumulated imports have a super additive effect on itc decision making

an empirical examination of information barriers to trade in insurance this paper uses direct evidence to evaluate whether asymmetric information is a barrier to trade in the largest market for private insurance in the world life insurance we report several findings that seem difficult to reconcile with the conventional theory of insurance under asymmetric information we conjecture that sellers may know their costs of production better than consumers in this market as in those for most other products

are all tastes constant and identical abstract george stigler and gary becker have attempted to eliminate the concepts of changing preferences and varying preferences across individuals from economic theory by postulating a household production function hpf stigler and becker reinterpret changing tastes as changes in the constraints used to produce utility from commodities the postulated changes in the hpf however are no less arbitrary than assertions of changing or different preferences and add no explanatory power furthermore problems of addiction taste change and weakness of will do not fit the constant tastes praradigm very well the stigler becker approach also involves infinite regress problems a change in the demand for x can be interpreted as an increase in x s ability to produce z where z is the true object of desire but how are we to explain a change in the demand for z

industry rent seeking and the filing of unfair trade complaints abstract this paper adopts a rent seeking framework to explain the incidence of antidumping and countervailing duty complaints brought to the u s international trade commission and the department of commerce tobit analysis on all 3 digit sic industries is employed to examine the relationship between the frequency of unfair trade complaints and such factors as industry concentration unionization capital intensity and levels and or changes in employment price cost margins and import penetration large capital intensive industries particularly those facing employment losses and rising import shares are found to be most likely to file complaints protection of quasi rents accruing to capital and labor rather than protection of monopoly returns appears to be the primary impetus behind the filing of unfair trade complaints

an analysis of factors influencing the anti dumping behaviour in india the use of anti dumping measures as a trade protection tool has increased phenomenally during the last decade one significant aspect of this new trend is the increasing involvement of developing countries india is one such country which has emerged as a very frequent user of anti dumping measures surpassing even the traditional users it had initiated more than 300 anti dumping cases by the end of 2002 03 many of these cases are against developing countries most of the cases are concentrated in narrow range product groups like chemicals and petrochemicals iron and steel pharmaceuticals and textiles this study examines india s experience with anti dumping measures the main objective of the study is to identify the factors which might have influenced the anti dumping behaviour in india discussion of these factors shows that imports have increased considerably this is particularly true for a number of developing countries facing dumping charges in india at the same time many of the domestic producers of the like products have performed poorly during the last decade such trends may instigate the import competing industries to seek anti dumping protection and may also influence the authority to provide that however the results of our statistical exercise show that although imports and performance of the domestic industry might have influenced the initiation of anti dumping cases these factors did not seem to significantly influence the final decision of the authority the results rather indicated a tendency on the part of the authority to provide anti dumping protection to industries which are characterised by a large number of firms

anti dumping a growing problem in international trade this paper discusses the issue of anti dumping ad proliferation ad is used more frequently by more countries and against more products than ever in its history i review ad filing patterns with an emphasis on the scope of countries and industries seeking protection recent trends suggest that the widespread embrace of ad protection makes the prospect for ad reform increasingly unlikely ad is no longer being used solely by high income developed countries it is increasingly being used by middle income and even lower income countries new users have chosen to use ad very intensively per dollar of imports the new users have filed ad cases up to 15 20 times more frequently than the traditional ad users such as the us and eu the evolving set of ad users complicates ad negotiations in the near term strong opposition by the us and eu makes reform a highly unlikely outcome in the longer run rising use of ad against the us and eu could conceivably weaken their support for ad yet the same trends that might finally cause the us and eu to realise ad is a failed policy will likely make reform impossible

human capital vs signalling explanations of wages increases wages by directly increasing the worker s productivity this learning explanation is usually associated with human capital theory however it seems unlikely that learning explains all the wage differences associated with schooling and work history better educated workers are not a random sample of workers they have lower propensities to quit or to be absent are less likely to smoke drink or use illicit drugs and are generally healthier it is unlikely that employers make full use of differences in propensities to quit or to be absent or sick when hiring workers these characteristics are often not directly observed and the americans with disabilities act precludes firms from using either poor health or the likelihood of future sickness as a hiring criterion unless it is directly related to job performance however if low levels of education are associated with these unfavorable employee characteristics and employers are allowed to take education into account when hiring workers we would expect employers to favor better educated workers as a means of reducing their costs of sickness and job turnover in turn students will take these hiring criteria into account when deciding how long to stay in school students will choose a length of schooling to signal their ability to employers and employers will demand a minimum level of schooling

a non nested test of the aids vs the translog demand system abstract a non nested test is used to examine the relative explanatory power of the aids and translog demand system empirical results based on chinese urban household data suggest that these two demand systems are not significantly different in explanatory power and elasticity estimates

anti dumping protection in a liberalising country mexico s anti dumping policy and practice the use of anti dumping policy has been steadily growing in recent decades and so has the theoretical and empirical literature on anti dumping however while developing countries as a whole have become at least as active as the traditional anti dumping regimes the usa the eu canada and australia the literature is almost exclusively concerned with the latter group this article gives an overview of anti dumping policy and practice in mexico one of the leading new anti dumping regimes it assesses how anti dumping has expanded since the country began liberalising trade in the mid 1980s and discusses how the policy has been applied in a protectionist way that is not dissimilar to policy practice in the traditional user countries

analysis of india s policy reforms he process of major economic reforms undertaken in the indian economy has now completed six years of implementation the economy has entered into a new phase of development directed towards becoming globally competitive through opening up to trade foreign investment and technology inflows the unilateral reforms of the trade and domestic policies of india along with reforms of the tax regime since 1991 represent a significant departure from the policy framework of the previous four decades and are important to the future course of the indian economy there is an ongoing debate in india regarding the likely impacts of sectoral reforms on output employment and other variables that affect the economic wellbeing of the country s population it thus becomes important to evaluate the effects of such policy reforms on factor prices output and trade along with inter sectoral movement of resources viz land labour and capital to address these issues we use a 34 sector computable general equilibrium cge model for india though such ex ante analysis may not be replicated ex post due to various macroeconomic and other factors that our model does not capture the positive results nevertheless go a long way in establishing the credibility of the reforms process we hope therefore that our analysis will provide a more solid underpinning for the ongoing policy debate the paper proceeds as follows the policy relevance of our research is outlined in section 2 in section 3 we elaborate briefly the essential features of the india cge model the various policy scenarios are discussed in section 4 and the results are presented in section 5 in section 6 we report on the sensitivity of the model to changes in some of its essential parameters our findings are summarised in section 7

nobel lecture the economic way of looking at behavior an important step in extending the traditional theory of individual rational choice to analyze social issues beyond those usually considered by economists is to incorporate into the theory a much richer class of attitudes preferences and calculations while this approach to behavior builds on an expanded theory of individual choice it is not mainly concerned with individuals it uses theory at the micro level as a powerful tool to derive implications at the group or macro level the lecture describes the approach and illustrates it with examples drawn from my past and current work
