booming sector economic activity in paraguay 1973 86 a case of dutch disease the primary purpose of this study is to investigate the applicability of the dutch disease model as a means of explaining the changing sectoral composition of output for paraguay in the period 1973 86 the consequences of booming sector activity for 1 the distribution of income as it affects wages and 2 the in stability of export earnings for paraguay are examined the dutch disease model predicts that the consequences of booming activity will include a contraction of non booming sector activity as well as a real appreciation of the exchange rate these outcomes are tested in several single and multiple equation estimable models for the case of paraguay

bridging the gap between laboratory experiments and naturally occurring markets an inferred valuation method abstract several recent studies have found important differences between behavior in the laboratory and the field we explore two possible causes for the divergence social concerns and unfamiliarity with the traded good consistent with our conceptual model we find that people overstated their preferences for relatively familiar goods with normative attributes and understated their preferences for a relatively unfamiliar good with low normative motivations in the laboratory as compared to the field we also find that for goods with a normative dimension a new method we refer to as inferred valuation has the potential to narrow the lab field gap in some cases willingness to pay obtained from a conventional valuation elicitation method is more than twice the value from the new inferred valuation approach

does altruism undermine existence value abstract the debate over the use of contingent valuation for existence values or passive use values has failed to explore the validity of motives for such values one potential motive altruism has conflicting implications for benefit cost analysis depending on whether the altruist is paternalistic this paper constructs models of three types of altruism and shows how benefit cost analysis responds to each type of altruism how damage assessment and restoration depend on each type and the implications of a population of heterogeneous altruists

the skewness of commodity futures returns abstract this article studies the relation between the skewness of commodity futures returns and expected returns a trading strategy that takes long positions in commodity futures with the most negative skew and shorts those with the most positive skew generates significant excess returns that remain after controlling for exposure to well known risk factors a tradeable skewness factor explains the cross section of commodity futures returns beyond exposures to standard risk premia the impact that skewness has on future returns is explained by investors preferences for skewness under cumulative prospect theory and selective hedging practices

absorbing a windfall of foreign exchange dutch disease dynamics abstract the permanent income rule is seldom the optimal response to a windfall of foreign exchange such as that from a resource discovery absorptive capacity constraints require domestic investment and investment in structures requires non traded inputs the supply of which is constrained by the initial capital stock this particularly when combined with intra sectoral capital immobility delays adjustment and creates short run dutch disease symptoms as the real exchange rate sharply appreciates and overshoots its long run value optimal revenue management requires investing in the domestic non traded goods sector and a slow build up of consumption accumulation of foreign assets adjusts to accommodate the time paths of domestic consumption and investment

external disturbances and the independence of monetary policy under the crawling peg in colombia abstract this study examines the impact of external economic disturbances and the independence of monetary policy in colombia a five equation econometric model is estimated the results indicate that external occurrences have had a significant impact on colombian prices and output contrary to the assumptions of the monetary approach to the balance of payments a substantial portion of foreign reserve flows were sterilized and the short run balance of payments offset to domestic credit expansion was less than complete

dutch disease economics and the colombian export boom abstract dutch disease models predict a primary export boom may result in deindustrialization due to an appreciating real exchange rate this paper examines the effects on the colombian economy of large increases in foreign exchange earnings from coffee and illegal drug exports as predicted by dutch disease models the relative price of nontraded goods rose and the real exchange rate appreciated once the boom was over both were slow to return to previous levels nontraded sectors are shown to have increased their growth rates during the boom years while traded goods experienced slower growth non coffee exports also grew more slowly econometric estimation shows that the real exchange rate was sensitive to the price of coffee and fiscal expansion that sectoral production adjusts to the exchange rate and level of absorption as predicted and that non coffee exports respond to changes in the real exchange rate and foreign demand the paper concludes with a discussion of economic policy in response to the export boom

macroeconomic policy in an oil exporting economy with foreign exchange controls the sudden and sharp increases in oil prices during the past decade and the discovery and extraction of oil in the north sea have recently contributed to a renewal of interest in the macroeconomic problems of oil exporting countries in general and those of industrialized and semi industrialized oilexporting countries such as the uk and mexico in particular the economic implications of the north sea oil revenues for the british economy have been hotly debated by forsyth and kay 1980 1981 worswick 1980 barker 1981 corden 1981 and byatt et al 1982 the effects of oil and gas revenues on the economies of canada mexico the netherlands norway and the uk have also been the subject of analysis and discussion in barker and brailovsky 1981 despite their important contribution these studies fall short of formulating a comprehensive theoretical framework for the study of macroeconomic policy in oil exporting countries in general the resurgence of interest in the macroeconomics of oil exporting economies and the lack of a satisfactory theoretical framework emphasize the need for the explicit introduction of an oil sector into macroeconomic models of the open economy the more recent studies by buiter and purvis 1983 eastwood and venables 1982 corden and neary 1982 and neary and purvis 1982 have gone some way towards meeting this need but they are better suited to the study of macroeconomic policy in developed oil exporting countries such as the united kingdom where highly developed financial markets already exist 1 without exception all these studies assume that the economy under consideration operates with a floating exchange rate and that the private capital is internationally mobile they also invariably ignore the short term and the long term financial repercussions of changes in oil income that operate via the government budget constraint and the asset position of the private sector these assumptions are however inappropriate for most oil exporting countries in the middle east africa and latin america the purpose of this paper is to examine the short run and long run macroeconomic consequences of an increase in oil revenues in an oil exporting country characterized by strict foreign exchange controls on private capital flows we attempt to do this in the context of a keynesian underemployment model of the type analysed for example by turnovsky and kaspura 1974 branson 1976 and argy and salop 1979 but with domestic prices set according to a mark up rule along the lines advocated for example by fetherston and godley 1978 1981 unlike argy and salop but in line with other recent contributions to the macroeconomic theory of open economies the present paper explicitly allows for the existence of the government budget constraint and analyses the macroeconomic effects of changes in oil revenues both in the short run when

the economic effects of windfall gains in export earnings 1975 1978 abstract this paper reviews the effects of recent dramatic increases in beverage prices 1975 1978 on a sample of countries that are highly dependent on these commodities in most countries the increase in producer prices was restricted allowing substantial sums to accrue to the central government and the commodity organizations the countercyclical impact of fiscal policy was often limited by the rise in development spending this policy stance and the lack of monetary restraint contributed to a substantial rise in imports consequently in many of the sample countries the external reserve position in 1978 was little better than before the windfall gain

an inferred valuation method although estimates of people s values for public goods are often needed to conduct cost benefit analysis existing value elicitation methods are prone to a number of well documented biases we argue that some of these biases result because people derive utility from the act of saying they are willing to pay for a good to counteract this phenomenon we consider an approach that asks people to predict or infer others values for a good instead of asking people to state their own value both a conceptual model and results from a laboratory experiment lend support for the new approach

the value of mortality risk reductions pure altruism a confounder this paper examines public valuations of mortality risk reductions we set up a theoretical framework that allows for altruistic preferences and subsequently test theoretical predictions through the design of a discrete choice experiment by varying the tax scenario uniform versus individual tax the experimental design allows us to verify whether pure altruistic preferences are present and the underlying causes we find evidence of negative pure altruism under a coercive uniform tax system respondents lower their willingness to pay possibly to ensure that they are not forcing others to pay at a level that corresponds to their own higher valuations this hypothesis is supported by the observation that respondents perceive other individuals valuations to be lower than their own our results suggest that public valuations of mortality risk reductions may underestimate the true societal value because respondents are considering other individuals welfare and wrongfully perceive other people s valuations to be low

is hypothetical bias a universal phenomenon a multinational investigation a concern with the contingent valuation method cvm is the finding that hypothetical and real statements of value often differ we test whether hypothetical bias broadly defined is independent of location by comparing real and hypothetical votes on a dichotomous choice referendum in china france indiana kansas and niger we find significant differences in hypothetical bias across locations and reject the hypothesis that hypothetical bias is independent of location as opposed to the typical finding reported in the literature subjects in niger significantly understated their willingness to pay in the hypothetical referendum

what experimental protocol influence disparities between actual and hypothetical stated values preferences elicited in hypothetical settings have recently come underscrutiny causing estimates from the contingent valuation method to bechallenged due to perceived hypothetical bias given that the receivedliterature derives value estimates using heterogeneous experimentaltechniques understanding the effects of important design parameters onthe magnitude of hypothetical bias is invaluable in this paper we addressthis issue statistically by using a meta analysis to examine data from 29experimental studies our empirical findings suggest that on averagesubjects overstate their preferences by a factor of about 3 in hypotheticalsettings and that the degree of over revelation is influenced by thedistinction between willingness to pay and willingness to accept publicversus private goods and several elicitation methods

the truth the whole truth and nothing but the truth a multiple country test of an oath script hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation the general criticism is that survey responses reflect how people would like to behave rather than how they actually behave in our study of climate change and carbon emissions reductions based on the increasing bulk of evidence from psychology and economics regarding the effects of making promises we investigate the effect of an oath script in a contingent valuation survey the survey was conducted in sweden and china and its results indicate that an oath script has significant effects on respondent behavior in answering willingness to pay wtp questions in both countries the shares of zero wtp responses and extremely high wtp responses decrease when an oath script is used resulting in lower variance furthermore the conditional wtp decreases in the chinese but not in the swedish sample we also find that the effect of the oath script is not generally dependent on respondent characteristics and the few differences we observe vary with the countries

electricity as a traded good abstract electric power has traditionally been classified as a non traded good produced and consumed within the country of origin more recently electricity has been traded across national borders and in certain cases viz bhutan has been the dominant export in other situations it is used to repay debts owed to neighboring countries this paper investigates the role of electricity as the primary export analyzes its valuation and then goes on to evaluate the impact on the terms of trade we conclude that in the medium term the electric power exporting economy would be better off developing its manufacturing sector to diversify its exposure and to protect its trade interests the case of bhutanese hydro electricity exports to india is studied and the change in trade advantage with every increase in power tariff is ascertained it is found that a 1 26 annual increase in non food consumer prices is correlated with a 1 increase in electricity export tariff while the causality from electric power tariff to indian manufactures prices is not established statistically a change in manufactures prices feeding back into consumer prices in bhutan is statistically significant suggestions are offered for bhutan to reduce dependence on indian imports and to diversify its export market exposure

industrial policy and exchange rate scepticism the aim of the present paper is to put in historical perspective the development thinking on the relationship between industrial and exchange rate policies the first section focuses on the thought of the so called pioneers of development economics specifically their preference for protectionism and their belated recognition that an exchange rate policy could act as a substitute to it in the second one we analyze the exchange rate skepticism that arises out of the theories that identify a foreign constraint to growth in addition to the one revealed by the pioneers the third section briefly complements the previous discussion with reference to macroeconomic formulations that allow for short run contractionary effects of a devaluation reinforcing the skepticism in question in the fourth section we discuss the revival of development thinking in the 1980s and its discussion about east asian trajectories a literature that placed great emphasis on industrial policy finally in the fifth section we discuss the new historical facts and the new development macroeconomics models that are putting an end to exchange rate skepticism

elicitation formats and the wta wtp gap a study of climate neutral foods we conduct a field valuation experiment where we vary the valuation method contingent valuation vs inferred valuation as well as the payment format dichotomous choice vs payment card willingness to accept and willingness to pay valuations are elicited in a within subjects design for foods with climate neutral labels we find a similar gap for valuations elicited with the contingent or the inferred valuation method however we also find that the gap can be muted by using a payment card elicitation format

market microstructure and securities values evidence from the tel aviv stock exchange abstract this paper examines the value effects of improvements in the trading mechanism selected stocks on the tel aviv stock exchange were transferred gradually from a daily call auction to a mechanism where the call auction was followed by iterated continuous trading sessions this event was associated with a positive and permanent price appreciation the cumulative average market adjusted return over a period that started five days prior to the announcement and ended 30 days after the stocks started trading by the new method was approximately 5 5 in addition we find positive liquidity externalities spillovers across related stocks and improvements in the value discovery process due to the improved trading method finally there was a positive association between liquidity gains and price appreciation

winning isn t everything corruption in sumo wrestling although the theoretical literature on corruption is well developed empirical work in this area has lagged because it has proven difficult to isolate corrupt behavior in the data in this paper we look for evidence of corruption in an unlikely place the highest echelons of japanese sumo wrestling this paper provides strong statistical evidence documenting match rigging in sumo wrestling a non linearity in the incentive structure of promotion leads to gains from trade between wrestlers on the margin for achieving a winning record and their opponents we show that wrestlers win a disproportionate share of the matches when they are on the margin increased effort can not explain the findings winning on the bubble is more frequent when the two competitors have met often in the past success on the bubble tends to rise over the course of a wrestler s career but declines in his last year consistent with the game theoretic predictions wrestlers who are victorious when on the bubble lose more frequently than would be expected the next time they meet that opponent suggesting that part of the payment for throwing a match is future payment in kind systematic differences across wrestling stables suggest that the stables play a role in facilitating the corruption in times of increased media scrutiny the match rigging disappears this abstract was borrowed from another version of this item

booming sector and de industrialisation in a small open economy this paper presents a theoretical analysis of the dutch disease the phenomenon whereby a boom in one traded goods sector squeezes porfitability in other traded goods sectors both by directly bi

neoclassical theory versus prospect theory evidence from the marketplace several experimental studies have provided evidence that suggest indifference curves have a kink around the current endowment level these results which clearly contradict closely held economic doctrines have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory e g prospect theory which invokes psychological effects this paper pits neoclassical theory against prospect theory by investigating data drawn from more than 375 subjects actively participating in a well functioning marketplace the pattern of results suggests that prospect theory adequately organizes behavior among inexperienced consumers but consumers with intense market experience behave largely in accordance with neoclassical predictions moreover the data are consistent with the notion that consumers learn to overcome the endowment effect in situations beyond specific problems they have previously encountered this transference of behavior across domains has important implications in both a positive and normative sense

the varieties of resource experience natural resource export structures and the political economy of economic growth many oil mineral and plantation crop based economies experienced a substantial deceleration in growth following the commodity boom and bust of the 1970s and early 1980s this article illustrates how countries dependent on point source natural resources those extracted from a narrow geographic or economic base such as oil and minerals and plantation crops are predisposed to heightened economic and social divisions and weakened institutional capacity this in turn impedes their ability to respond effectively to shocks which previous studies have shown to be essential for sustaining rising levels of prosperity analysis of data on classifications of export structure controlling for a wide array of other potential determinants of governance shows that point source and coffee and cocoa exporting countries do relatively poorly across an array of governance indicators these governance effects are not associated simply with being a natural resource exporter countries with natural resource exports that are diffuse relying primarily on livestock and agricultural produce from small family farms do not show the same strong effects and have had more robust growth recoveries

coffee money and inflation in colombia abstract the purpose of this paper is to analyse the relationship between coffee money inflation and international competitiveness in colombia the basic hypothesis being investigated is that higher lower prices of coffee will tend to result through the accumulation of international reserves in higher lower inflation in turn this higher inflation will generate for a given rate of devaluation of the nominal exchange rate a reduction of the real exchange rate with the consequent loss of competitiveness in the non coffee tradable goods sector a dutch disease type of model is developed to discuss analytically the relationship between coffee prices money creation and competitiveness in the short and long run empirical results for 1952 1980 are presented these results support the hypothesis that there has been a positive relationship between the price of coffee money creation and inflation in colombia

the short run impact of fluctuating primary commodity prices on three developing economies columbia ivory coast and kenya abstract computable general equilibrium models are used to study the short run impact of fluctuating primary commodity prices on the economies of columbia ivory coast and kenya the results indicate that these economies are destabilized by primary commodity price fluctuations unless governments act to hold real domestic absorption constant to achieve this however would require foreign exchange reserves in excess of the level normally available to these governments for the purpose of stabilizing domestic economic activity

pairs trading of chinese and international commodities we investigate the profitability of a pairs trading strategy using chinese and international commodity futures contracts covering the period january 2004 to february 2018 we use a time series appr

prosocial behavior and incentives evidence from field experiments in rural mexico and tanzania abstract incentive based schemes for natural resource conservation are based on the premise that offering payments to groups of land users will motivate them to organize collectively to provide environmental services in contrast research from behavioral economics shows that introducing monetary incentives can undermine collective action that is motivated by social norms in such a case payment could have perverse impacts in view of this dichotomy we conducted choice and field experiments in rural mexico and tanzania to test the response of prosocial behavior to incentives the field experiments involved voluntary participation in real communal tasks under different incentive structures findings suggest that payments help raise participation where people are otherwise uninterested but that participation in communal tasks can be high irrespective of the incentive if social norms favoring participation are present in tanzania high individual payments do not undermine participation although they appear to reduce people s satisfaction from the task relative to when there is no payment in mexico group payments made through village authorities yield lower participation where people distrust leaders challenges to conducting field experiments in our research settings limit what we can conclude from our work but the findings raise important points and suggest areas for further research

external shocks and adjustment in a mineral dependent economy a short run model for zambia abstract standard dutch disease analyses would suggest that mineral price declines reverse the effects of mineral booms in particular that the real depreciation caused by the fall in export prices helps revive the traded sectors notably manufacturing zambia s experience however shows that the sectoral impacts of external shocks are much more complex to investigate the tradeoffs inherent in economic adjustment policies including those currently advocated by the international monetary fund imf we use a multisector general equilibrium model the study shows that policies even those directed at a specific sector have indirect but not necessarily benign effects on the rest of the country

resource boom wages and unemployment theory and evidence from the norwegian petroleum experience the effects of norwegian petroleum activities on nominal wages and the rate of unemployment are analyzed in this paper the theoretical model is based on standard theory of segmented labor markets increased nominal wages in the petroleum sector will unambiguously increase the wage level and the rate of unemployment increased petroleum employment will under realistic assumptions also raise the wage level the effect on the rate of unemployment in this case is ambiguous the empirical model is embedded in reduced forms of the theoretical model and the estimated parameters are consistent with the theoretical results

capturing the risk premium of commodity futures the role of hedging pressure abstract we construct long short factor mimicking portfolios that capture the hedging pressure risk premium of commodity futures we consider single sorts based on the open interests of hedgers or speculators as well as double sorts based on both positions the long short hedging pressure portfolios are priced cross sectionally and present sharpe ratios that systematically exceed those of long only benchmarks further tests show that the hedging pressure risk premiums rise with the volatility of commodity futures markets and that the predictive power of hedging pressure over cross sectional commodity futures returns is different from the previously documented forecasting power of past returns and the slope of the term structure

natural disasters and labor markets abstract while it is clear that natural disasters have serious welfare consequences for affected populations less is known about how local labor markets in low income countries adjust to such large shocks combining data from the indonesia family life survey the desinventar database the u s geological survey and district level employment indicators this paper explores how a large earthquake in indonesia affected labor market outcomes in particular the evolution of wages across sectors i find that the earthquake had a positive effect on wage growth for workers who were employed in the agricultural sector at baseline i propose two mechanisms for this result a higher growth rate of the price of rice and a downward shift in the supply of workers in the agricultural sector i show that evidence mainly supports the latter labor shifted out of the agricultural sector into the construction sector raising the marginal product of labor in agriculture

dynamic hypothetical bias in discrete choice experiments evidence from measuring the impact of corporate social responsibility on consumers demand abstract this paper is aimed at studying the dynamics of consumers preferences for corporate social responsibility the data come from both a discrete choice experiment dce and a field experiment conducted in a real market setting the results show that in a static setting first month predictions of a standard dce study and real market shares are statistically similar for the various profiles of corporate social responsibility however as time evolves real market shares present some dynamic patterns that are not mirrored by the standard dce predictions the overall conclusion is that differences between real market behavior and dce data can be attributed to the lack of learning experience or adaptation in dce surveys rather than to the hypothetical nature of the experiments

theft gift giving and trustworthiness honesty is its own reward in rural paraguay in developing countries lacking legal enforcement villagers may use implicit contracts to minimize crime i construct a dynamic limited commitment model in which a thief cannot commit to forego stealing but is induced to steal less by the promise of future gifts combining survey data on production theft gifts and trust with experiments measuring trustworthiness i provide supporting evidence farmers living near more relatives or with plots that are difficult to steal from give fewer gifts and trust more and those living near more relatives also experience less theft giving increases when trust is lower and the threat of theft is greater

commodity currencies and the real exchange rate abstract this paper shows that a change in the terms of trade of a commodity exporting country could cause the relative price of nontraded goods to rise or fall depending on the strength of income and substitution effects

taxing tourism and subsidizing non tourism a welfare enhancing solution to dutch disease abstract using a combined analysis of a general equilibrium and a partial equilibrium this study models the impacts of a combined policy tool based on taxing tourism and subsidizing non tourism in a tourism dependent destination the results suggest that such a policy tool while widely discussed in economics literature may not be suitable for a tourism destination as it might have adverse effects on local welfare
