the solution to the tullock rent seeking game when r 2 mixed strategy equilibria and mean dissipation rates in tullock s rent seeking model the probability a player wins the game depends on expenditures raised to the power r we show that a symmetric mixed strategy nash equilibrium exists when r 2 and that overdissipation of rents does not arise in any nash equilibrium we derive a tight lower bound on the level of rent dissipation that arises in a symmetric equilibrium when the strategy space is discrete and show that full rent dissipation occurs when the strategy space is continuous our results are shown to be consistent with recent experimental evidence on the dissipation of rents

nonlinear dynamics in deviations from the law of one price a broad based empirical study abstract in this paper we test empirically the validity of the law of one price using data for five major bilateral us dollar exchange rates and nine goods sectors during the recent floating exchange rate regime since the early 1970s using threshold autoregressive models we find strong evidence of nonlinear mean reversion in deviations from the law of one price with plausible convergence speeds consistent with theoretical arguments on international goods markets arbitrage under transactions costs and with an emerging strand of empirical literature these results contribute towards forming a consensus view in favor of discrete regime switching in deviations from the law of one price and the presence of differing nonzero transactions costs across a broad range of goods and countries

are asian real exchange rates stationary by applying the newly developed nonlinear stationary test advanced by kapetanios et al journal of econometrics 112 2003 359 in examining the stationary property of 11 asian real exchange rates this paper rejects unit root in 8 us dollar based and 6 japanese yen based rates whereas the augmented dickey fuller adf test has led to no rejection at all

the specification of the probability functions in tullock s rent seeking contest abstract in his model of a rent seeking contest tullock g 1980 efficient rent seeking in buchanan j m tollison r d tullock g eds toward a theory of the rent seeking society texas a and m university press college station pp 97 112 uses a simple concrete specification for the probability functions which determine the probability that a player wins the contest given the bids made by the players we discuss in general terms a set of conditions that can be imposed on probability functions in this game next we show that the specification chosen by tullock is the unique one that satisfies these conditions

environmental quality competition and eco labeling abstract a three stage game of investment environmental quality provision and price competition is developed to study the impact of green technology investment eco labeling in a duopoly model of vertical product differentiation the firms incentives to invest in green technologies depend on their relative cost structure when firms are identical with respect to fixed costs both firms will always invest but if one firm is more efficient in investing then the other firm may or may not invest depending on the level of unit cost of investment quality competition will be tighter when the low quality firm is more efficient and looser when the high quality firm is more efficient in investing socially optimal investment for both firms is always positive but lower than in the duopoly solution in the absence of environmental externalities the quality dispersion chosen by profit maximizing firms may be too high or too low while environmental externalities increase the possibility low quality dispersion that is too low within the market solution finally and importantly ecolabeling can be used as a means of reducing excessive investment and increasing environmental quality that is too low

stock markets banks and growth panel evidence this paper investigates the impact of stock markets and banks on economic growth using a panel data set for the period 1976 98 and applying recent gmm techniques developed for dynamic panels on balance we find that stock markets and banks positively influence economic growth and these findings are not due to potential biases induced by simultaneity omitted variables or unobserved country specific effects

nonlinear purchasing power parity under the gold standard 1 introductionrecent theoretical analysis of purchasing power deviations see e g dumas 1992 sercu uppal and van hull 1995 and o connell and wei 1997 demonstrates how transactions costs or the sunk costs of international arbitrage induce nonlinear adjustment of the real exchange rate to purchasing power parity ppp globally mean reverting this nonlinear process has the important property of exhibiting near unit root behavior for small deviations from ppp since small deviations from ppp are left uncorrected if they are not large enough to cover the transactions costs or the sunk costs of international arbitrage a parametric nonlinear model suggested by the theoretical literature that captures the nonlinear adjustment process in aggregate data is the exponential smooth transition autoregression model estar of ozaki 1985 a smooth rather than discrete adjustment mechanism is motivated by the theoretical analysis of dumas 1992 also as postulated by terasvirta 1994 and demonstrated theoretically by berka 2002 in aggregate data regime changes may be smooth rather than discrete given that heterogeneous agents do not act simultaneously even if they make dichotomous decisions 1 recent empirical work e g michael nobay and peel 1997 taylor peel and sarno 2001 peel and venetis 2002 has reported empirical results that suggest that the estar model provides a parsimonious fit into a variety of data sets particular for monthly data for the interwar and postwar floating period as well as for annual data spanning 200 years as reported in lothian and taylor 1996 in addition nonlinear impulse response functions derived from the estar models show that although the speed of adjustment for small shocks around equilibrium will be highly persistent larger shocks mean revert much faster than the glacial rates previously reported for linear models rogoff 1996 in this respect the estar models provide some solution to the ppp puzzle outlined in rogoff 1996 2the estar model can also provide an explanation of why ppp deviations analyzed from a linear perspective appear to be described by either a nonstationary integrated i 1 process or alternatively described by fractional processes see e g diebold husted and rush 1991 taylor peel and sarno 2001 and pippenger and goering 1993 show that the dickey fuller tests have low power against data simulated from an estar model michael nobay and peel 1997 and byers and peel 2003 show that data that is generated from an estar process can appear to exhibit the fractional property that this would be the case was an early conjecture by acosta and granger 1995 given that the estar model has a theoretical rationale whereas the fractional process is a relatively nonintuitive one the fractional property might reasonably be interpreted as a misleading linear property of ppp deviations granger and terasvirta 1999 whereas the empirical work employing estar models provides some explanation of the glacially slow adjustment speeds obtained in linear models there is one aspect of the empirical work that is worthy of further attention a second way of explaining the rogoff puzzle raised by rogoff himself 3 is to relax the assumption that the equilibrium real exchange rate is a constant see e g canzoneri cumby and diba 1996 and chinn and johnston 1996 theoretical models such as that of balassa 1964 and samuelson 1964 imply a nonconstant equilibrium in the real exchange rate if real productivity growth rates differ between countries 4 nonlinear models that incorporate proxies for these effects are found to parsimoniously fit post bretton woods data for the main real exchange rates see venetis paya and peel 2002 and paya venetis and peel 2003 naturally models that ignore this effect may generate misleading speeds of ppp adjustment to shocks in this regard the empirical results of hegwood and papell 2002 for the gold standard period are particularly interesting

the effects of exchange rate volatility on commodity trade between the united states and mexico author affiliation mohsen bahmani oskooee department of economics p o box 413 bolton hall 822 university of wisconsin milwaukee milwaukee wi 53201 usa bahmani uwm edu corresponding authorscott w hegerty department of economics p o box 413 university of wisconsin milwaukee milwaukee wi 53201 usa hegertys beloit edu acknowledgment we would like to thank our anonymous referees for their valuable comments any error however is ours 1 introductionwith the breakdown of the bretton woods system in 1973 real exchange rates began to fluctuate greatly as volatility increased exporters and importers could no longer be as certain of the real prices of their goods this increased risk would affect their expected profits and thus influence their decision to trade exchange rate uncertainty has been shown to have affected trade flows between countries and across sectors but it has had both positive and negative effects in different studies increased volatility has had important implications in assessing the costs and benefits of various exchange rate regimes as well as of exchange rate controls in this study we assess the effect of this volatility on trade between the united states and mexico based on the exports and imports of 102 industries from 1962 to 2004 and we find that it plays a role only for a small number of individual industries 1intuitively one might surmise that uncertainty toward the real price of traded goods may reduce trade flows as risk averse buyers and sellers face possible losses due to exchange rate fluctuations and thus choose not to partake in risky dealings on the other hand it has been hypothesized that exchange rate risk can actually increase trade flows as importers and exporters opt to increase the volume of trade to attain a certain income making up for a decrease in the per unit value of a good by increasing the number of units bought or sold the bulk of the literature points to the former conclusion as reviewed by mckenzie 1999 and more recently by bahmani oskooee and hegerty 2007 the trading relationship between mexico and the united states is an important one more than 70 of mexico s exports go to the united states likewise mexico is still the second largest market for u s exports after canada mexico has taken advantage of its relatively inexpensive labor to attract u s manufacturing firms and expand its exports mexico imports automobile parts from the united states for example and then exports completed automobiles assembly line factories known as maquiladoras have attracted much attention but with the growth of china and competition from its even less expensive labor this sector has actually declined in addition the united states is mexico s main trading partner for agricultural products thus the two countries share important trade flows across a wide variety of sectors table 1 shows a breakdown of mexico s top 15 export and import industries in order of largest to smallest dollar value or trade share of the 102 industries that we analyze in our study the rankings are given for the year 1980 in order to capture the preliberalization trade structure and for the year 2004 to capture flows in the years after mexico joined the general agreement on tarifs and trade gatt and the north american free trade agreement nafta 2table 1 top 15 industries by dollar value of trade table omitted see article image the most striking observation in table 1 is that the same manufacturing industries occupy top spots for both exports and imports road motor vehicles exports of which have grown in importance since 1980 were also the top mexican import in both 1980 and 2004 likewise such manufacturing industry categories as telecommunications apparatus other electrical machinery machinery and appliances non electrical and office machines make up a large part of both export and import flows

the black market exchange rate vs the official rate in testing ppp which rate fosters the adjustment process abstract in testing the purchasing power parity theory ppp researchers hardly pay attention to the speed with which the exchange rate adjusts to a change in relative prices in this paper we show that the speed of adjustment is faster when the black market exchange rate is used in testing the ppp as compared to the official exchange rate this could be another reason as to why central banks should unify the two rates

dissipation of contestable rents by small numbers of contenders the theory of rent seeking with its origins in the observations of gordon tullock 1967 or to use jagdish bhagwati s 1982 proposed term the theory of directly unproductive profit seeking activities is concerned with the potentially adverse effects on resource allocation of incentives to cap ture and defend artificially contrived rents and transfers the scope for so cial loss proposed by the theory derives from the relation between the value of a contestable prize and the value of the resources attracted into the con test to determine the beneficiary of the prize underlying this social loss is a specification of how rational behavior by optimizing agents links the value of the prize sought to the resources expended it has been traditional to assume competitive behavior in describing the activities of lobbying and influence seeking then if some further condi tions are satisfied l the total value of the resources expended precisely equals the value of the prize sought so dissipation is complete 2 conse quently the social cost associated with contestability of a rent can be in ferred from the value of the rent itself and the detailed and hard to come by information on individual outlays made in the course of the contest be comes unnecessary by basing their analyses on competitive dissipation contributors to the rent seeking literature see the review by robert tollison 1982 have been able to presume that the observed value of a contested rent is an exact measure of the associated social cost of monopoly power or regu lation similarly in the trade theoretic literature where the rights contested are to quota premia or revenues from trade taxes krueger 1974 bhagwati

free entry and efficient rent seeking this paper concerns rent seeking and the extent to which rents are dissipated under various circumstances gordon tullock s 1967 insight that expenditures made to capture an artificially created transfer represent a social waste suggested that the cost to the economy of monopoly and regulation is greater than the simple harberger 1954 deadweight loss indeed under tullock s original formulation and in the extensions of his work by krueger 1974 and posner 1975 rents are exactly dissipated at the social level 1 is spent to capture 1 so that the total welfare loss from such activities is equal to the harberger triangle plus the rectangle of monopoly profits

banking sector development and interest rate volatility in emerging economies over the last decades macroeconomic stability is said to be one of the major concerns of emerging economies financial sector as a core of macroeconomic stability has been under close consideration of policy makers the relationship between interest rate uncertainty and banking sector development as one of the most important indicators of financial sector development especially for emerging economies has not received enough attention in the literature perhaps this article is the most comprehensive study that investigates the relationship between interest rate uncertainty and banking sector development for a large group of emerging economies to do this the short run and long run models using a bounds testing approach to cointegration for 12 emerging economies over the period 1980 2011 have been developed estimated results from all models indicate that interest rate uncertainty has significant effect on banking sector development in both short run and long run phenomena in the majority of countries

purchasing power parity and country characteristics evidence from panel data tests abstract we examine long run purchasing power parity ppp using panel data methods to test for unit roots in us dollar real exchange rates of 84 countries we find stronger evidence of ppp in countries more open to trade closer to the united states with lower inflation and moderate nominal exchange rate volatility and with similar economic growth rates as the united states we also show that ppp holds for panels of european and latin american countries but not for african and asian countries our findings demonstrate that country characteristics can help explain both adherence to and deviations from long run ppp

influencing rent seeking contests this paper shows that a policy that uniformly increases contestants effort costs can lead to an increase in total effort in asymmetric settings this levels the playing field and therefore encourages weaker players who otherwise would have stayed out to enter paradoxically a contest designer whose only objective is to maximize total effort may thus wish to make rent seeking more difficult these results suggest that the often lamented bureaucratic red tape might in fact be a rational response to the problem of attracting lobbyists to participate in a contest

real exchange rate adjustment in european transition countries abstract in single equation tests real exchange rates show mean reversion for nine of 10 central and eastern european transition countries for the period january 1993 to december 2005 because of the shift from controlled to market economies and accompanying crises failed policy regimes and changes in exchange rate regimes unit root tests for transition countries often require allowance for structural changes accounting for structural breaks gives substantially faster mean reversion speeds than those found for major industrialized countries these fast adjustment speeds are plausible transition countries had perhaps 10 years to make unprecedented adjustments required for accession to the european union a number of papers have applied non linear models to the central and eastern european countries this paper investigates four non linear models and compares them with piece wise linear break models the break models appear superior in detecting mean reversion for the central and eastern european transition countries

purchasing power parity in less developed and transition economies a review paper abstract the concept of purchasing power parity ppp has been the subject of numerous studies many of which have been unable to prove conclusively this core principle of international finance although industrialized countries have received most of the attention studies that focus on less developed and transition economies have also attained mixed results this study surveys trends in this branch of the literature highlighting the econometric advances that have sought to solve this puzzle while pointing out that more needs to be done to address the reasons that might cause ppp not to hold

the design of rent seeking competitions in the standard tullock model of rent seeking as a noncooperative game aggregate expenditures by seekers can equal exceed or fall short of total rents depending on what is assumed about the number of seekers and the marginal return to a seeker s investment if the supply of an input into the rent seeking process is controlled by a politician who receives payment from seekers for it the indeterminacy of the process becomes a less serious problem he supplies it and designs the rent seeking game to maximize his wealth the author derives expressions for the number of seekers and the marginal return parameter which maximize the politician s wealth in one input and two input rent seeking processes

dynamic rent seeking games the present paper analyses rent seeking games in which competitors for a rent can act and react finitely or infinitely often it argues for an infinite move model as the most appropriate specification of a model of rent seeking dynamic equilibrium analysis of this game suggests that wasteful expenditures in rent seeking competitions are lower than previously studied static simultaneous move games predict journal of economic literature classification numbers d72 c73

financial liberalisation stockmarkets and economic development abstract during the 1980s and 1990s many developing countries dcs have been engaged in far reaching reforms of their financial systems liberalising them and making them more market oriented this liberalisation involving inter alia financial de repression has been inspired partly by the work of the mckinnon 1973 and shaw 1973 m s school this paper suggests that in addition to financial de repression there has been a major new element in the development of dc financial systems in recent years the establishment and fast expansion of stockmarkets these markets have played a key role in the internal as well as external financial liberalisation processes in leading dcs further the paper finds that the actual behaviour of these markets in many countries has led to outcomes which undermine the effects of the higher real interest rates arising from financial de repression

the choice of numeraire currency in panel tests of purchasing power parity we investigate the implications of the choice of numeraire currency on panel tests of purchasing power parity under the current regime of flexible exchange rates by conducting panel unit root tests with twenty one different base currencies we show that the conditions necessary for numeraire irrelevancy are not supported empirically and that the choice of numeraire currency can and does matter for ppp the evidence of ppp is stronger for european than for non european base currencies distance between the countries and volatility of the exchange rates are the most important determinants of the results

on cross country differences in the persistence of real exchange rates abstract previous findings of long run purchasing power parity come mainly from data for industrial countries raising the issue of whether the results suffer sample selection bias and exaggerate the general relevance of parity reversion this study uncovers substantial cross country heterogeneity in the persistence of deviations from parity the results show that it is more likely rather than less likely to find parity reversion for developing countries than industrial countries although some persistence variations may partly reflect country differences in structural characteristics such as inflation experience and government spending a considerable portion of those variations seems unaccounted for

real and nominal effective exchange rates of african countries during 1971q1 2012q4 one of the macro variables that are included in most models is the exchange rate overall performance of a country s exchange rate is measured by changes in nominal or real effective exchange rate reer these rates are constructed and published mostly for industrial countries by international organizations less developed countries have received little attention in this article the two rates are constructed for 21 african countries using quarterly data over the period 1971q1 2012q4 as an application we use the reers to show that even in africa the movements of the real effective rates follow a nonlinear path

purchasing power parity in developing countries multi period evidence under the current float abstract using panel unit root tests we examine purchasing power parity ppp for us dollar real exchange rates of developing countries during the current floating rate period since evidence of ppp may vary from period to period we examine the data for moving 10 year periods from 1976 85 up to 1990 99 we organize panels based on country characteristics influencing the validity of ppp those characteristics include openness inflation and the level and growth rate of per capita gdp although we find stronger evidence of ppp after 1980 our examination of panel data over 15 10 year periods yields only limited support for ppp

equity markets and growth cross country evidence on timing and outcomes 1980 1995 abstract the rapid expansion of organized equity exchanges in both emerging and developed markets has prompted policymakers to raise important questions about their macroeconomic impact yet the need to focus on recent data poses implementation difficulties for econometric studies of dynamic interactions between stock markets and economic performance in individual countries this paper overcomes some of these difficulties by applying recent developments in the analysis of panels with a small time dimension to estimate vector autoregressions for a set of 47 countries with annual data for 1980 1995 after describing recent theories on the role of stock markets in growth and considering a pure cross sectional empirical approach our panel vars show leading roles for stock market liquidity and the intensity of activity in traditional financial intermediaries on per capita output the findings underscore the potential gains associated with developing deep and liquid financial markets in an increasingly global economy

economic integration and political disintegration in a world of trade restrictions large countries enjoy economic benefits because political boundaries determine the size of the market under free trade and global markets even relatively small cultural linguistic or ethnic groups can benefit from forming small homogeneous political jurisdictions this paper provides a formal model of the relationship between openness and the equilibrium number and size of countries and successfully tests two implications of the model firstly the economic benefits of country size are mediated by the degree of openness to trade secondly the history of nation state creations and secessions is influenced by the trade regime

do real exchange rates follow a nonlinear mean reverting process in developing countries in an effort to fight relatively high inflation many developing countries try to manage their nominal exchange rates through official intervention in addition developing countries tend to have high transportation costs tariffs and nontariff barriers these factors are among the sources of generating nonlinearity in real exchange rates and hence some nonlinear adjustment toward purchasing power parity ppp in developing countries in this paper we employ monthly real effective exchange rate reer data of 88 developing countries and test the null of nonstationarity versus an alternative of linear stationarity by the means of a conventional unit root test and compare the results with those obtained from a new test in which the null is the same but the alternative hypothesis is nonlinear stationarity the latter test supports the ppp theory in more developing countries compared with the former test suggesting that nonlinear adjustment toward ppp in developing countries is an important phenomenon reported country characterizations indicate that reversion in reer occurs more often for high inflation countries and for countries with high flexibility in their exchange rates

financial market development and trade openness evidence from emerging economies international trade is said to be the engine of economic growth despite an enormous effort to explain this phenomenon the relationship between financial market development and trade openness and integration into the world economy is still an enigma this article investigates the relationship between financial market development and trade openness to do this we develop a long run and short run model a bounds testing approach to cointegration for 18 emerging economies over the period 1980 to 2011 estimates from all models show that financial market development including both the stock market and the banking sector has significant effect on trade openness in both short run and long run phenomena in the majority of countries despite many similarities among emerging economies additional evidence suggests that the link between either stock market development or banking sector development with trade openness works via each country s specific structure

rigging the lobbying process an application of the all pay auction textabstractin a world where a politician can explicitly auction off a prize to the high bidder the standard auction literature can be used to analyse political behavior the justice system however precludes politicians from explicitly selling the prize to the highest bidder thus politicians cannot let it become public knowledge that they are in the business of selling political favors an institution has emerged in political markets to overcome this constraint which are termed as lobbying lobbyists make implicit payments to the politician through campaign contributions if these up front payments were rebated to those failing to receive the prize it would be clear that the politician was selling favors this article has examined an interesting principle arising in all pay auctions this principle states that a politician wishing to maximize political rents may find it in his best interest to exclude certain lobbyists from participating in the lobbying process particularly lobbyists valuing most the political prize

interpreting real exchange rate movements in transition countries abstract real exchange rate movements in the transition economies during the initial transition period were unusually large by the standards of other economies and periods using cross sectional evidence this paper documents how real exchange rates were generally misaligned at the onset of the transition and how most of this misalignment was eliminated over a relatively short period turning to the time series dimension the paper shows that estimates from a consensus type single equation model of the real exchange rate are well behaved and provide a good fit for exchange rate movements in the early transition period the results highlight the role of productivity driven real exchange rate movements that can be interpreted as reflecting both the impact of the structural transformation process on productivity in the tradables sector per se and the effects of changes in tradables versus non tradables productivity furthermore the results show that the relationship between productivity and real exchange rates holds both when productivity is increasing and when it is falling

validity of purchasing power parity for selected latin american countries linear and non linear unit root tests abstract the aim of this study is to examine empirically the validity of ppp in the context of unit root tests based on linear and non linear models of the real effective exchange rate of argentina brazil chile colombia mexico peru and venezuela for this purpose we apply the harvey et al 2008 linearity test and the non linear unit root test kruse 2011 the results show that the series with linear characteristics are argentina brazil chile colombia and peru and those with non linear characteristics are mexico and venezuela the linear unit root tests indicate that the real effective exchange rate is stationary for chile and peru and the non linear unit root tests evidence that mexico is stationary in the period analyzed the results show support for the validity of ppp in only three of the seven countries

characterizing equilibrium rent seeking behavior a reply to tullock rent seeking contests can have different rules for designating the successful rent seeker we have investigated the case where the rule is that the successful rent seeker is the contender who has made the greatest outlay in the rentseeking quest hillman and samet this issue it is well known that for such contests there exists no nash equilibrium in pure strategies i e contenders choosing outlays as strategies we show however that there does exist a unique equilibrium in mixed strategies the equilibrium has the characteristic that the expected value of outlays made by the rival contenders equals the value of the prize being contested without regard for the number of contenders hence for any number of contenders rent dissipation is expecta

long run equilibrium and total expenditures in rent seeking a comment although corcoran is mathematically correct i believe his comment is not very helpful in order to discuss the matter in some detail the reader should consult table 7 1 from my original efficient rent seeking reproduced on page 92 1 this shows the equilibrium investment of each individual different numbers of individuals playing the game n and differing values of r table 7 2 also reproduced on page 93 shows the total investment

a general analysis of rent seeking games in this paper we reconsider the basic model of efficient rent seeking we stress the importance of the shape of the players reaction curve in order to understand the impact of the technology of rent seeking on the structure of the outcome of the game we give a complete characterization of the pure strategy equilibria moreover the possibility of preemption by a stakelberg leader is discussed according to the nature of the technology of rent seeking available to the agents

efficient rents 1 rent seeking behavior in the long run we have analyzed long run behavior in rent seeking under several conditions and behavioral hypotheses the question of interest is whether or not the long run expenditures will exactly equal the value of the rents our results depend on the type of competitive response which is assumed to exist in the long run and on the r value governing the probability of winning

read my lips but only if i was elected experimental evidence on the effects of electoral competition on promises shirking and trust abstract we experimentally test whether electoral competition reduces shirking behavior by office holders and increases citizens trust using a novel multi person investment game with voting we indeed find that elected office holders shirk less i e they back transfer more to citizens relative to investments than randomly appointed office holders surprisingly this effect is not driven by electoral competition inflating office holders promises instead elected office holders feel more committed to their promises than their randomly appointed counterparts elections initially also increase citizens trust because voters select candidates with the right kind of promises neither low nor non credibly high however over the course of the entire experiment we find no evidence that electoral competition increases citizens trust

orchestrating rent seeking contests contests have different sometimes quite complex organisational structures in particular while most of the existing literature focusses on simultaneous contests multistage contests are also quite frequently encountered this paper seeks to provide a rationale for the latter by endogenising the choice of a contest structure which is made by an organiser of a contest interested in maximising the efforts expended by the contenders

real exchange rates in small open oecd and transition economies comparing apples with oranges abstract we find that productivity gains in tradables cause an appreciation of the real exchange rate via both tradable and nontradable prices in the cee 5 and have no affect in the baltic countries while they lead to a depreciation of the real exchange rate of tradables in oecd economies that overcompensates the appreciation due to nontradable prices rising net foreign liabilities lead to a real appreciation in the baltic countries instead of the expected depreciation found in oecd and cee 5 countries these differences are due to the different impact of the fundamentals on the real exchange rate depending on the time horizon studied

a quantitative reassessment of the finance growth nexus evidence from a multivariate var abstract the long run relationship between financial development and economic growth is examined in a multivariate vector autoregression var framework using 10 sample countries difficulties surrounding the cross country regressions and bivariate time series studies are outlined the long run financial development and output relationships are identified in a cointegrating framework through tests of over identifying restrictions we find bi directional causality between financial development and economic growth in all the sample countries conclusions that stand distinct from those in the existing empirical literature we attribute our findings to i analysis of a higher dimensional system ii a new method of identifying the long run economic relationships and iii a new approach to long run causality testing

equilibrium exchange rates in transition economies taking stock of the issues in this paper we present an overview of a number of issues relating to the equilibrium exchange rates of transition economies of the former soviet bloc in particular we present a critical overview of the various methods available for calculating equilibrium exchange rates and discuss how useful they are likely to be for the transition economies amongst our findings is the result that the trend appreciation usually observed for the exchange rates of these economies is affected by factors other than the usual balassa samuelson effect such as the behaviour of the real exchange rate of the open sector and regulated prices we then consider three main sources of uncertainty relating to the implementation of an equilibrium exchange rate model namely differences in the theoretical underpinnings differences in the econometric estimation techniques and differences relating to the time series and cross sectional dimensions of the data the ensuing three dimensional space of real misalignments is probably a useful tool in determining the direction of a possible misalignment rather than its precise size copyright blackwell publishers ltd 2006

tullock s rent seeking contest with a minimum expenditure requirement we consider a rent seeking contest of the kind introduced by tullock 1980 in which two players compete for a monopoly rent we extend the contest by requiring that if a player puts forward an effort his expenditures must be larger than or equal to some minimum level we show that depending on the model parameters the number of nash equilibria of the extended model can be zero one two or four furthermore it turns out that the extent of rent dissipation in a nash equilibrium of the extended model can be larger than equal to or smaller than the extent of rent dissipation in the unique nash equilibrium of the original model

voluntary eco labeling and the price premium international environmental organizations propose voluntary eco labeling as a market incentive to promote industry to operate in an ecologically sustainable and environmentally friendly manner a microeconomic analysis questions whether voluntary eco labeling will cause producer profits in a competitive industry to decline and whether eco labeling will necessarily generate different prices for labeled and unlabeled product using wood product as an example results identify conditions that may exist when firms lose profits even under a voluntary system and where existing production constraints may lead to a single price regardless of labeling

the incidence of overdissipation in rent seeking contests tullock s analysis of rent seeking and overdissipation is reconsidered we show that while equilibrium strategies do not permit overdissipation in expectation for particular realizations of players mixed strategies the total amount spent competing for rents can exceed the value of the prize we also show that the cross sectional incidence of overdissipation in the perfectly discriminating contest ranges from 0 50 to 0 44 as the number of players increases from two to infinity thus even though the original analysis of overdissipation is flawed there are instances in which rent seekers spend more than the prize is worth

purchasing power parity under the gold standard 1 introduction long run purchasing power parity lrppp a mainstay of international economic theory has proved difficult to back up empirically many attempts have been made using various time series of data yet results continue to be mixed a standout exception to these mixed results is presented by diebold husted and rush 1991 whose work has been interpreted as very strong evidence of lrppp because of their across the board rejection of the unit root for a large sample of real exchange rates baillie 1996 p 51 cites diebold husted and rush as reestablishing purchasing power parity as a meaningful long run concept despite the substantial mixed results of other studies these mixed results are usually attributed to the power problems associated with standard unit root tests especially for small samples diebold husted and rush 1991 overcome these shortcomings by loosening the structure of the model to allow a longmemory process diebold husted and rush 1991 model real exchange rate behavior using autoregressive fractionally integrated moving average arfima models in doing so they reject the unit root for 16 real exchange rates from the gold standard era in favor of a fractionally integrated alternative hypothesis a long memory process is essentially a stationary one but where the autocorrelations take far longer to decay than the exponential rate associated with the autoregressive moving average arma class baillie 1996 p 6 this observation implies that purchasing power parity ppp holds but in some cases only in the extreme long run we agree with diebold husted and rush 1991 that the structure of standard unit root tests is overly restrictive however we offer a different solution to this problem from standard unit root tests one must conclude that either all deviations from ppp are permanent or all deviations dissipate over time however there is a third possibility that has both theoretical and empirical support unit root tests do not allow the possibility that while most deviations dissipate a few remain as permanent shocks real exchange rates may show substantial mean reversion but to a changing mean rather than to the constant ppp value this idea which we call quasi purchasing power parity qppp draws support from the balassasamuelson theory which asserts that productivity shocks can have permanent effects on real exchange rates samuelson 1994 p 202 criticizes economists who tried to use ppp as a guide even when substantive microeconomic changes had taken place between the previous putative equilibrium period and the new status quo he cites an example from the 1980s when the actual yen dollar exchange rate was 150 yen per dollar according to ppp the equilibrium exchange rate was 200 yen per dollar yet the rate proceeded to drop to 110 yen per dollar and below in qppp terms this situation would represent not a lack of mean reversion but evidence of an equilibrium that had shifted away from ppp this is a form of the penn effect whereby a rich country in comparison with a poor one will be estimated to be richer than it really is if you pretend that the simplified cassel version of purchasing power parity is correct samuelson 1994 p 201 we assert that this penn effect can occur not just between rich and poor countries but between any two countries if one of these countries is affected by a permanent external shock qppp also supports engel s 1996 p 1 proposition that the real exchange rate evolves as the sum of two processes a stationary but persistent component and a non stationary component it is generally held that while the exchange rate deviates from its long run equilibrium value in the short run it eventually converges to that equilibrium value in the long run the question then is what is that long run equilibrium value some argue it is the ppp level while others argue that there is a complex set of factors determining the long run value including such things as the relative labor productivities at home and abroad engel 1996 p

smooth structural breaks and the stationarity of the yen real exchange rates this article examines and solves an interesting paradox in the literature that the tests for purchasing power parity ppp based on the yen real exchange rates rers refute the ppp hypothesis more often than those with other major currency based rers and the evidence is sensitive to the sample period used using a new empirical methodology accounting for both nonlinearity and multiple smooth temporary breaks in the data we show that the puzzling finding is due to the failure to take into account the long but temporary large rise and fall in the yen rers the results illustrate that the yen rers in the post bretton woods period are likely mean reverting with linear or nonlinear adjustment toward large long swing type of infrequent smooth temporary changes around constant equilibrium values supporting the validity of ppp and resolving the paradox

monetization financial liberalization and economic development barter sector in 1954 55 the monetized sector contributed 69 to the net national product of india the share of the monetized sector increased to 78 6 of the net national product by 1974 75 during this period the explicit objective of monetary policy in india was to help accelerate the pace of economic development in an environment of reasonable price stability there are several versions of the financial liberalization hypothesis but the one put forward by ronald mckinnon is chosen here because of its succinctness and easy amenability to empirical verification 2 mckinnon s theory in essence deals with the effect of financial liberalization on the accumulation of capital through a policy of high real interest rates this formulation has been made operational by estimating the response of real demand for money balances and private investment to alternative rates of return under the implicit assumption that these are the only two alternative forms of assets held by the private sector 3 all this is predicated on the assumption that the effective limitation on the rate of real capital formation is the supply of real savings and not the inadequate willingness to invest most underdeveloped countries have a significant barter sector a reduction in the share of the barter sector can help to further accelerate the accumulation of capital in a barter system a good share of the factors of production is tied up in distribution away from production to achieve the double coincidence required in such a system with the

financial liberalization financial sector development and growth evidence from malaysia abstract the objective of this paper is to examine whether financial development leads to economic growth or vice versa in the small open economy of malaysia using time series data from 1960 to 2001 we conduct cointegration and causality tests to assess the finance growth link by taking the real interest rate and financial repression into account the empirical evidence suggests that financial liberalization through removing the repressionist policies has a favorable effect in stimulating financial sector development financial depth and economic development are positively related but contrary to the conventional findings our results support robinson s view that output growth leads to higher financial depth in the long run

eco labels trade and protectionism eco labels are suspected to serve protectionist purposes we analyze the choice between an environmental standard and a voluntary eco label scheme in a partial trade model with one domestic firm and one foreign firm the environmental standard will only apply to the domestic firm while both firms can adopt the eco label pollution is production related and domestic consumers demand products that are produced in an environmentally friendly way our results show that it may be optimal for the domestic government to introduce an eco label and get both firms to adopt the label instead of setting an environmental standard however to what extent this policy serves protectionist purposes is ambiguous in particular if the willingness to pay for green products is sufficient to cover the pollution abatement costs of the foreign firm foreign firm profit will increase while domestic firm profit will decrease compared to the outcome with a domestic environmental standard on the other hand if the willingness to pay for green products is insufficient the foreign firm would be better off with a domestic environmental standard

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

revisiting purchasing power parity in oecd this study revisits purchasing power parity theory ppp in the 34 oecd countries during january 1994 august 2013 we use a new panel stationary test with both sharp breaks and smooth shifts a novel approach to panel unit root testing proposed by bahmani oskooee et al 2014 the results indicate that the ppp holds in half of the 34 oecd countries these results indicate the importance of proper modelling of both sharp breaks and smooth shifts in real effective exchange rate series of oecd countries

testing ppp in the non linear star framework abstract we apply the standard adf test and a new test that incorporates non linearity in time series to the real effective exchange rates of 23 industrial countries the new test provides support for ppp in more countries than the adf test
