status in markets this project tests for the effect of social status in a laboratory experimental market we consider a special box design market in which a vertical overlap in supply and demand ensure that there are multiple equilibrium prices we manipulate the relative social status of our subjects by awarding high status to a subset of the group based on one of two procedures in the first a subject s score on a trivia quiz determines his or her status in another subjects are assigned randomly to a higher status or lower status group in both treatments we find that average prices are higher in markets where higher status sellers face lowerstatus buyers and lower when buyers have higher status than sellers across all sessions the higher status side of the market captures a greater share of the surplus earning significantly more than their lower status counterparts

non monetary incentives and opportunistic behavior evidence from a laboratory public good game this study reports data from a laboratory experiment that investigates the incentive effect of three distinct social communication schemes on free riding behavior we use performance based approval and disapproval ratings and a linear public good game to address the above issues the treatments vary in terms of subjects opportunities to anonymously assign 1 only the approval ratings to other group members 2 only the disapproval ratings to other group members and 3 either the approval or the disapproval ratings to other group members but not both to the same group member after they play a standard linear public good game despite the nash prediction of zero individual contribution in all three treatments the data show that the disapproval points generate significantly higher contribution than the approval points the treatment in which subjects could communicate either the approval or the disapproval points produces the highest level of contribution we discuss the implications that these findings may have for efficient design of organizations jel d03 h41 c72 c92

peer pressure and partnerships partnerships and profit sharing are often claimed to motivate workers by giving them a share of the pie but in organizations of any significant size the free rider effects would seem to choke off

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

the role of warnings in regulation keeping control with less punishment abstract regulatory agencies frequently present violators with warnings not pursuing prosecution if the violation ceases upon receipt of the warning we show how such warnings may help regulators to keep control prosecution is costly for the regulator and insufficient prosecution efforts yield low penalties thus with a limited regulatory budget threats of harsh sanctions are credible only if the number of violators is low this produces multiple nash equilibria if firms may make mistakes the economy can accidentally switch from one equilibrium to another warnings reduce substantially the probability of such accidental switches from the full compliance to the no compliance equilibrium

some international evidence on the quantity theory of money this paper develops a two equation model of money interest rates and inflation based on the simple quantity theory an d fisher s hypothesis about nominal interest rates the model has both within equation and cross equation restrictions that are tested on long run average cross country data covering the period 1962 88 the major finding is that the restrictions cannot be easily rejected and this suggests that the behavior of interest rates and inflation in a major part of the postwar period can be understood in terms of classical monetary forces copyright 1993 by ohio state university press

nonmonetary sanctions and rewards in an experimental coordination game abstract a growing body of experimental research documents that nonmonetary sanctions and rewards may be important instruments for enforcing efficient behavior this study contributes to this literature by reporting results from a laboratory experiment the experiment is designed to test whether nonmonetary sanctions or rewards alone can yield the optimal level of efficiency in a game with pareto ranked equilibria performance based disapproval and approval ratings assigned by group members are used as proxies for nonmonetary sanction and reward respectively although these ratings are costless and payoff neutral results show that expression of disapproval facilitates coordination on the most efficient equilibrium in contrast statement of approval induces subjects to converge towards the most inefficient outcome we conclude that induced approval and disapproval ratings have asymmetric behavioral effects on coordination

who talks with whom the role of repeated interactions in decentralized forest governance summary this article suggests that efforts to study decentralization outcomes would benefit from widening the unit of analysis from the local government administration to the local governance system many individual local governments especially in developing countries lack the human and physical resources to be effective governors by themselves it is thus useful to recognize the linkages between different governance actors the empirical analysis based on observations in bolivia s forestry sector finds that the degree of connectivity between the actors in a municipal governance system helps explain why some systems are more effective than others 2003 elsevier ltd all rights reserved

incomplete information strengthens the effectiveness of social approval we present a theoretical model of a public good game in which the expression of social approval induces pro social behavior using a laboratory experiment with earned heterogeneous endowments we test our model the main hypothesis is that the expression of social approval increases cooperative behavior even if reputation building is impossible we vary the information available and investigate how this affects the expression of social approval and individual contributions the expression of social approval significantly increases contributions however the increase is smaller if additional information is provided suggesting that social approval is more effective if subjects receive a noisy signal about others contributions jel c72 c91 d71 d83

purchasing power parity in the long run a test of the dollar pound exchange rate 1890 1978 this paper tests the purchasing power parity ppp hypothesis by analyzing t he long run tendency of the dollar pound exchange rate using data sin ce 1890 two different models are considered 1 a na ive model and 2 a modified monetary model the conditions of propor tionality and symmetry cannot be rejected when using the naive model the final results using the monetary model however indicate that t he existence of permanent deviations from ppp cannot be ruled out copyright 1987 by ohio state university press

agricultural policy market barriers and deforestation the case of mexico s southern yucatan summary this paper examines the linkages between agricultural policies and deforestation in a development frontier of southern mexico focusing on support programs targeted at buffering farmers from structural reforms we argue that local barriers to market participation condition the responsiveness of farmers to program incentives thereby constituting a key channel through which agricultural policies impact the environment an econometric model parameterizes the influence of two programs procampo and alianza para el campo on cultivation consistent with an economic environment characterized by market barriers results suggest that program support even when decoupled from production decisions significantly determines land use and deforestation

equilibrium relationships between money and other economic variables central to the quantity theory of money are a number of important propositions about the long run equilibrium effects of changes in the nominal stock of money on other economic variables a standard way of testing these propositions is to use quarterly or annual data explicitly model the lag structure and then derive the long run solution of the model from the empirical estimates an alternative is to use some type of smoothing procedure to approximate positions of equilibrium and then to use these transformed data directly in testing hypotheses the national bureau technique of averaging data over reference cycle phases is one such method robert lucas s application of fourier transforms in two illustrations of the quantity theory of money 1980 is another and john geweke s method 1982 of frequency decomposition is a third an entirely different way of approaching the problem is to use cross country average rather than time series data as the basic units of observation the advantage according to lucas is that since the two quantity theoretic laws that he examines are obtained as characteristics of steady states or limiting distributions of theoretical models the ideal experiment for testing them would be a comparison of long term average behavior across economies with different monetary policies but similar in other respects p 1006 in this paper i conduct such an experiment the data that i use are for 20 oecd countries over the period 1956 80 the specific relationships that i examine are those between money and the price level money and real income money and interest rates and money and exchange rates in the main the data accord well with the quantity theoretic model classical neutrality holds there is evidence of a fisher effect albeit a less than complete effect on interest rates finally the data are consistent with long run purchasing power parity and hence correspondingly with a long run monetary approach to exchange rate determination

the effects of structural adjustment on deforestation and forest degradation in lowland bolivia bolivia s structural adjustment policies initiated in 1985 increased poverty among certain groups but this did not lead to widespread migration to the agricultural frontier nor did adjustment greatly affect the average area planted in annual crops by small lowland farmers structural adjustment contributed to large scale forest clearing for soybean production for export and to a lesser extent forest degradation by lumber companies the economic benefits generated by soybean and timber expansion may have outweighed the environmental costs but alternative policies might have reduced those costs and improved the distribution of the benefits

flexible exchange rates prices and the role of news lessons from the 1970s recent experience with flexible exchange rate systems has led to renewed interest in the operation of foreign exchange markets as reflected in many recent studies of the principal determinants of exchange rates the 1970s witnessed the dramatic alteration of the international monetary system from a regime of pegged exchange rates which prevailed for about a quarter of a century since the bretton woods conference into a regime of flexible though managed rates as a consequence of the emergence of the new legal and economic system traders national governments and international organisations were confronted with new economic problems choices and instruments during the 1970s ex change rates fluctuated widely and inflation rates accelerated the international monetary system had to accommodate extraordinarily large oil related shocks which affected trade flows in goods and assets huge oil payments had to be recycled uncertainties concerning future developments in international politics reached new heights and the prospects for the world economy got gloomier these developments placed unprecedented pressures on the markets for foreign exchange as well as on other asset markets they were associated with a large slide in the value of the us dollar and resulted in speeding up the creation of new institutions like the european monetary system which provided the formal framework for the management of exchange rates among members

real exchange rates under the gold standard purchasing power parity is one of the most important equilibrium conditions in international macroeconomics empirically it is also one of the most hotly contested numerous recent studies for example have sought to determine the validity of purchasing power parity using data from the post bretton woods float and have reached different conclusions we assert that most such studies are flawed for two reasons first the post 1973 data contain by definition only a very limited amount of the low frequency information relevant for examination of long run parity second the dynamic econometric techniques used to model deviations from parity are typically quite crude with respect to admissible low frequency dynamics both deficiencies are rectified in the present paper with dramatic results we construct a new data set of 16 real exchange rates covering more than a century of the classic gold standard period and we study deviations from parity using long memory models that allow for subtle forms of mean

arima and cointegration tests of ppp under fixed and flexible exchange rate regimes real exchange rates between the united states and its major trading partners were calculated for the bretton woods and flexible exchange rate periods unit root tests indicate that purchasing power parity performed poorly in both periods tests for cointegration reveal limited instances in which it is possible to estimate the deviations from ppp as an error correcting model the estimated error correcting models indicate that foreign but not u s prices responded to deviations from ppp frenkel s 1981b finding that purchasing power parity ppp worked better during the 1920s than the 1970s caused considerable controversy for example davutyan and pippenger 1985 contend that the socalled collapse of ppp is a result of an increase in the relative importance of real versus monetary shocks they argue that the 1970s as opposed to the 1920s was characterized by real supply shocks and the international coordination of monetary policies the argument is that ppp did not fail rather there was an increase in the volatility of those factors giving rise to deviations from ppp hakkio 1984 reestimated ppp over the 1920s and 1970s using cross country tests i e sure estimates to improve the efficiency of his estimates he was able to support the hypothesis that ppp worked better in the 1970s than in the 1920s on the other hand papers by adler and lehman 1983 dornbusch 1980 frenkel 1981a junge 1985 and krugman 1978 report findings contrary to the ppp hypothesis moreover kenen and rodrik 1986 find that the volatility of real exchange rates has increased throughout the flexible rate period this paper tries to shed some light on the importance and persistence of the observed deviations from purchasing power parity under alternative exchange rate systems while it is interesting to compare ppp in the 1920s versus the 1970s it is equally useful to compare the 1960s versus the 1970s and 1980s if real supply shocks and lack of monetary coordination are characteristic of the latter period ppp should perform better in the 1960s to illustrate the issues involved consider the following econometric model of relative purchasing power

multi country evidence on the behavior of purchasing power parity under the current float abstract using panel data for the united states and 22 other oecd countries for the current float this paper presents evidence that despite substantial short term perturbations purchasing power parity actually performed much better than commonly believed average rates of growth of real exchange rates over long horizons bear little relationship either to average rates of growth of nominal exchange rates or to average inflation differentials thus implying a close to one to one relation between average rates of growth of nominal exchange rates and average inflation differentials panel data variants of standard unit root tests suggest that the real exchange rates of these countries can be characterized as mean reverting

structural adjustment and peasant agriculture in bolivia abstract this article examines how small farmers and their subsistence economy have fared under the policy reforms implemented since 1985 in bolivia the main post reform obstacles to increases in small farmer productivity and income are identified the analysis focuses on the comparison of incen tives and policies before and after the introduction of the new economic policy of 1985

poverty alleviation and tropical forests what scope for synergies abstract this paper explores the state of the art of the two way causal links between poverty alleviation and natural tropical forests microimpacts of rising poverty can increase or slow forest loss at the macrolevel poverty also has an ambiguous effect but it is probable that higher income stimulates forest loss by raising demand for agricultural land the second question is what potential forest led development has to alleviate a country s poverty in terms of producer benefits consumer benefits and economy wide employment natural forests widely serve as safety nets for the rural poor but it proves difficult to raise producer benefits significantly urban consumer benefits from forest an important target for pro poor agricultural innovation are limited and seldom favor the poor absorption of poor unskilled labor is low in forestry which tends to be capital intensive natural forests may thus lack comparative advantage for poverty alleviation there are few win win synergies between natural forests and national poverty reduction which may help to explain why the loss of tropical forests is ongoing this may have important implications for our understanding of sustainable forest development and for the design of both conservation and poverty alleviation strategies

nominal exchange rate regimes and the real exchange rate abstract two assumptions about the real exchange rate are common in the literature on international finance 1 the real exchange rate is a random walk 2 the time series properties of the real exchange rate depend on the nominal exchange rate regime this paper presents evidence that indicates that the random walk behavior of the real exchange rate is only a characteristic of the post world war ii period moreover our findings also suggest that what is crucial to the real exchange rate behavior is the particular historical period rather than the nominal exchange rate arrangement

macroeconomic change competitiveness and timber production a five country comparison summary this study analyzes how long run macroeconomic fluctuations have affected timber production levels in five tropical oil producing countries gabon cameroon papua new guinea png venezuela and ecuador the core hypothesis is that oil booms foreign borrowing and other major foreign exchange inflows slow down timber harvesting these inflows cause dutch disease depressing the price competitiveness of timber exports and other trade exposed sectors a qualitative examination of long run trends in the five countries is combined with simple econometrics the findings confirm a strong impact of competitiveness on logging substantial real currency devaluation can greatly accelerate timber exports yet in middle income countries with strongly expanding domestic timber markets ecuador cameroon venezuela home market demand also rises much with urban incomes and population when full or partial import protection occurs this translates into rising domestic production the relative weight of these two potentially significant factors varies widely so policies to influence extraction levels need to be tailored accordingly

no excuses for good behavior volunteering and the social environment abstract we study the effect of the social environment on the quantity and quality of voluntary labor contributions by extending benabou and tirole s 2006 image signaling framework we derive theoretical predictions on time volunteered given 1 the availability of excuses to stop volunteering and 2 the presence of an authority figure we test these predictions in an experiment where laboratory subjects are directly involved in a local nonprofit operation we find that in the absence of excuses to stop volunteering subjects volunteer longer without working less productively this increase is partially driven by subjects reluctance to be the first to stop volunteering the presence of an authority figure has little impact but the presence of peers has a positive and significant impact

rank as an inherent incentive evidence from a field experiment abstract money is the prime incentive considered in economic models however recent evidence indicates that people are also greatly concerned about their social rankings is this solely because rank brings tangible benefits or because in addition people have an inherent preference for high rank this paper deployed a field experiment that provides evidence for an inherent preference in the experiment vietnamese students enrolled in an english course performed significantly better on the official standardized international final test when they were told their rankings on practice tests than when they were not this result held even when this ranking information could not be reliably communicated thus severely attenuating the potential to bring tangible or status benefits

forest sustainability and the free trade of forest products cases from southeast asia abstract this paper introduces the theoretical arguments for and against trade liberalization of forest products considering forest sustainability and reports on the recent circumstances of three countries in southeast asia the philippines thailand and indonesia trade liberalization raises concerns about the negative effects on forest sustainability both in log importing countries that have already cut a large portion of their natural forests by commercial logging and now face a pressing need for reforestation and in forest product exporting countries that still have large areas of natural forest and enjoy export competitiveness in forest products

understanding the empirical literature on purchasing power parity the post bretton woods era abstract this paper argues that the empirical failure of statistical tests of ppp in post bretton woods data is largely due to the low power of the tests employed this result is demonstrated using monte carlo experiments on the size and power of different testing procedures a new procedure based on horvath and watson econometric theory 11 pp 984 1014 1995 has greater power than previous approaches using the horvath watson procedure we find moderate evidence in favor of ppp in the post bretton woods era

self confidence and personal motivation the maintenance and enhancement of self esteem has always been identified as a fundamental human impulse philosophers writers educators and of course psychologists have all emphasized the crucial role played by self image in motivation affect and social interactions the aim of this chapter is to bring these concerns into the realm of economic analysis and show that this has important implications for how agents process information and make decisions conversely the tools of economic modelling can help shed light on a number of apparently irrational behaviours documented by psychologists

an empirical examination of long run purchasing power parity using cointegration techniques this paper presents an empirical analysis of long run purchasing power parity ppp for five major exchange rates using recently developed econometric techniques on the cointegration of economic time series our empirical results are extremely unfavourable to the ppp hypothesis as a long run equilibrium condition even with an allowance made for measurement error and or tranportation costs in particular we are unable to reject the hypothesis of non cointegration of the exchange rate and relative prices for any of the countries concerned far from finding a stable long run proportionality between exchange rates and relative prices our results therefore suggest that they tend to drift apart without bound
