to float or to fix evidence on the impact of exchange rate regimes on growth we study the relationship between exchange rate regimes and economic growth for a sample of 183 countries over the post bretton woods period using a new de facto classification of regimes based on the actual behavior of the relevant macroeconomic variables in contrast with previous studies we find that for developing countries less flexible exchange rate regimes are associated with slower growth as well as with greater output volatility for industrial countries regimes do not appear to have any significant impact on growth the results are robust to endogeneity corrections and a number of alternative specifications borrowed from the growth literature

estimating the impact of currency unions on trade solving the glick and rose puzzle does leaving a currency union reduce international trade this paper uses a historical approach to re examine the puzzling large apparent impact of currency unions on trade i find that the early time series estimates were driven by the gradual decaying of colonial trade ties and other major geopolitical factors including warfare communist takeovers and ethnic cleansing episodes my methodology which carries lessons for other uses of gravity equations in policy analysis yields point estimates of currency unions on trade that are not statistically distinct from zero

external discipline and financial stability abstract the paper examines the costs and benefits of external discipline dollarization foreign short term debt from the point of view of the stability of the financial system of an emergent ldc economy external discipline solves the time inconsistency problem of central bank policy to help banks in trouble but at the cost of excessive liquidation of projects the latter may be quite important when the danger of coordination failure of investors is large

assessment of public acceptance and willingness to pay for renewable energy sources in crete abstract the aim of this study is to analyse and to evaluate the citizens public acceptance and willingness to pay wtp for renewable energy sources res in crete for this purpose a contingent valuation study was conducted using a double bound dichotomous choice format to elicit people s wtp and factors affecting it residents of 1440 households all over crete were interviewed face to face major conclusions can be used as a basis for sustainable energy planning for policies and the formulation of awareness campaigns and for res investment programs and projects in order to prepare implementation conditions and enhance public acceptance of renewable energy investments and programmes mean wtp per household was found to be 16 33 to be paid quarterly as an additional charge on the electricity bill larger willingness to pay was reported by those with high family income and residence size those having a higher level of energy information and awareness concerning climatic change those who have invested in some energy saving measures and those who suffer from more electricity shortages than others

is the cfa franc zone an optimum currency area summary in this paper we explore the features of the cfa franc zone and compare them to those of the economic and monetary union emu by operationalizing the criteria for an optimum currency area a structural vector autoregression method is used in modeling national outputs as determined by global regional and country specific shocks we find that domestic outputs of the cfa franc zone countries are strongly influenced by country specific shocks while regional shocks are far more important in european countries that have joined the emu the results suggest that the cfa franc zone countries are structurally different from each other and thus are more likely to be subjected to asymmetric shocks they do not appear to form an optimum currency area and the monetary union may have been a costly arrangement for the member countries unless they are compensated with some other benefits

bilateral trade and the eurozone evidence from new member countries the question of whether and how much currency unions increase bilateral trade among their members has garnered much attention since rose s seminal article the answer is as pertinent now as ever for both the eurozone s existing and future members as the financial crisis shook the very foundations of the european monetary union emu and brought its shortcomings into the spotlight this paper analyses the issue using the gravity equation with country pair and time fixed effects for a sample of the four new members of the emu slovakia slovenia malta and cyprus which has to the author s knowledge not been studied thus far due to their recent joining and controls drawn from the european union this paper finds a positive relationship between joining the emu and trade with emu partners but not with non emu partners

monetary union price level convergence and inflation how close is europe to the usa abstract the pattern of price dispersion across european and us cities from 1990 to 2004 is documented there is a striking decline in dispersion for traded goods prices in europe most of which took place prior to the launch of the euro dispersion in the euro area is now quite close to that of the usa this evidence provides useful facts for future work assessing the importance of various developments in europe harmonization of tax rates convergence of incomes and labor costs liberalization of trade and factor markets and increased coherence of monetary policy

estimating the effects of free trade agreements on international trade flows using matching econometrics abstract this paper provides the first cross section estimates of long run treatment effects of free trade agreements on members bilateral international trade flows using nonparametric matching econometrics our nonparametric cross section estimates of ex post long run treatment effects are much more stable across years and have more economically plausible values than corresponding ols cross section estimates from typical gravity equations we provide plausible estimates of the long run effects of membership in the original european economic community eec and the central american common market cacm between 1960 and 2000 and the estimates confirm anecdotal reports of these agreements effectiveness

the impact of disaster on the strategic interaction between company and government a company allocates a resource between safety effort and production the government earns taxes on production the disaster probability is modeled as a contest between the disaster magnitude and the two players safety efforts the model illustrates that safety efforts are strategic substitutes and inverse u shaped in the disaster magnitude the company s safety effort increases and the government s safety effort decreases in taxation taxation can ameliorate companies free riding on governments safety efforts with sufficiently large production the government prefers and the company does not prefer raising taxation above 0 for the government an upper limit usually exists above which taxation cannot be profitably increased the model shows how both or no players exert safety efforts when the disaster magnitude is small and large respectively and how they free ride on each other s safety efforts when the disaster magnitude is intermediate the company free rides when the unit production cost is low so that the large profits outweigh the negative impact of the disaster with endogenized taxation determined by the government the tax rate decreases in the disaster magnitude the unit production cost the government s unit cost of safety effort and how the company is negatively affected by the disaster the tax rate increases in the company s resource and how the government is negatively affected by the disaster the tax rate is weakly u shaped in the company s unit safety effort the model is illustrated with numerical examples and with the oil spill disasters by bp in 2010 and by exxon valdez in 1989

the case of risk premia for risky jobs revisited abstract the empirical evidence concerning the existence of risk premia for risky jobs is contradictory some results support the existence of these premia while others do not this note provides a theoretical justification for these contradictory results in a fairly general model where firms and workers can effect the probability of a workplace accident

residential consumers in the cape peninsula s willingness to pay for premium priced green electricity a number of studies have explored the willingness i e stated willingness as opposed to actual willingness of consumers to pay a premium for green electricity in developed countries however little is known about how this translates into an emerging economy context this study investigates the level of willingness of residential households in south africa s cape peninsula to pay a premium for electricity from renewable energy it methodologically drew on recent contributions in the literature on norm motivated behaviour used to identify testable factors that could influence residential consumers willingness to pay wtp interestingly the study found a significant positive link between household income and wtp for green electricity contrary to the findings of some previous studies not only are higher income households more likely to pay a premium but typically they are also willing to pay a bigger premium it was also further established that the view that green electricity is reliable involvement in the recycling of waste and the belief that everyone should contribute to green electricity generation drive the wtp

friedman redux external adjustment and exchange rate flexibility milton friedman argued that flexible exchange rates facilitate external adjustment recent studies find surprisingly little robust evidence that they do we argue that this is because they use composite multilateral exchange rate regime classifications which often mask heterogeneous bilateral relationships between countries constructing a novel bilateral exchange rate regimes data set for 181 countries over 1980 2011 we find a statistically strong relationship between exchange rate flexibility and the speed of external adjustment our results are supported by several natural experiments of exogenous changes in bilateral exchange rate regimes and by monte carlo simulations which show that tests based on standard multilateral regime classifications tend to have low statistical power

multiple faces of preferential market access their causes and consequences this paper suggests an integrated approach to study selection into and consequences of five modes of preferential economic integration agreements peias goods trade agreements gtas services trade agreements stas double taxation treaties dtts bilateral investment treaties bits and currency unions as well as currency pegs cuas a detailed descriptive analysis reveals typical integration patterns with dtts and bits often being first steps towards deeper integration we consider the effects of peias on bilateral goods trade services trade and fdi and provide conclusive evidence that single and combined peias are associated with positive effects not only on single outcome but typically on all outcomes investment liberalization through dtts and bits seems to be particularly beneficial since concluding them alone or in any combination with other agreements encourages goods trade even more than the liberalization of goods trade per se peter egger and georg wamser

social costs from proximity to hydraulic fracturing in new york state the study reports data from an economic choice experiment to determine the likely welfare impacts of hydraulic fracturing in this case using natural gas extracted by hydraulic fracturing for household electricity data were collected from an internet survey of 515 residents of new york state the welfare analysis indicated that on average households incur a welfare loss from in state hydraulic fracturing as the source of their electricity the evidence suggests that households in shale counties bear more costs from hf electricity than households out of shale counties the average welfare loss is substantive estimated at 40 46 of average household electric bills in shale counties and 16 20 of bills in counties without shale the evidence also suggests that relative proximity to hf well sites also increases cost borne by households

financial integration gdp correlation and the endogeneity of optimum currency areas the paper analyses the relationship between trade financial integration and business cycle synchronization in the euro area the introduction of the euro has had a noticeable impact on european financial markets evidence that capital market integration exerts a positive effect on output correlation has two major implications first it corroborates the hypothesis of the endogeneity of optimum currency areas whereby after joining a monetary union countries better meet standard oca criteria second it provides european policy makers with yet another reason to pursue financial integration in the euro area and in prospective members as well

willingness to pay for renewable energy primary and discretionary choice of british households for micro generation technologies this paper documents the policy context of renewable energy production in the european union the research adopts a choice experiment approach to investigate households wtp for these renewable energy technologies in the uk the micro generation technologies comprise solar photovoltaic micro wind solar thermal heat pumps and biomass boilers and pellet stoves the study compares the results from conditional and mixed logit models which estimate the distribution of utility coefficients and then derives wtp values as a ratio of the attribute coefficient to the price coefficient with a model in which the wtp distribution is estimated directly from utility in the money space the results suggest that whilst renewable energy adoption is significantly valued by households this value is not sufficiently large for the vast majority of households to cover the higher capital costs of micro generation energy technologies

games of monetary and fiscal interactions in the emu abstract this paper constructs various models of the emu and ecb when member countries have different objectives voting in pursuit of national interest can yield moderate and stable inflation the metaphor of walsh type contracts implements a monetary policy rule that averages the member countries most preferred rules in a repeated relationship where a country suffering a large adverse shock can use political bargaining to subvert the ecb s commitment the optimal rule should incorporate some flexibility to forestall that finally freedom of national fiscal policies undermines the ecb s monetary commitment this may justify fiscal constraints like the stability and growth pact

out in the cold iceland s trade performance outside the european union and european monetary union although entering currency and customs unions involve both costs and benefits an increasing body of research is finding that the benefits in terms of international trade creation are remarkably large focusing simply on the european monetary union emu rather than the broad range of currency unions studied by other authors we find that the trade impact of emu is smaller but still substantial our findings suggest that the iceland s trade could increase by about 60 and that the trade to gdp ratio could rise by 12 percentage points should iceland join the european union and emu copyright 2006 oxford university press

capital market imperfections and the theory of optimum currency areas this paper studies how within and cross country capital market imperfections affect the welfare effects of forming a currency union the analysis considers a bank only world where intermediaries compete in cournot fashion and monitoring and state verification are costly the first part determines the credit market equilibrium and the optimal number of banks prior to joining the union the second part discusses the benefits from joining a currency union a competition effect is identified and related to the added monitoring costs that banks may incur when operating outside their home country through an argument akin to the brander krugman reciprocal dumping model of bilateral trade however in our framework whether joining a union raises welfare of the home country is ambiguous it depends on the relative strength of investment creation and intermediation diversion effects

trade integration and business cycle convergence is the relation robust across time and space in this paper we investigate the relationship between trade intensity and the business cycle correlation using a panel data set taken from 24 countries over the period 1959 2003 most previous studies did not account for the possibility that the business cycle correlation may be influenced by unobservable country pair specific effects our estimates using both fixed and random effects methodologies suggest that trade intensity and the business cycle correlation are positively related to one another however detailed investigation shows that this relationship exists mainly for the european countries

following germany s lead using international monetary linkages to estimate the effect of monetary policy on the economy abstract forward looking behavior on the part of the monetary authority makes it difficult to estimate the effect of monetary policy interventions on output we present instrumental variables estimates of the impact of interest rates on quarterly real output for several european countries using german interest rates as the instrument these estimates confirm a strong forward looking bias in least squares estimates that persists even conditional on standard controls for the history of the system due to the potential for correlation of output shocks across countries we interpret our estimates as lower bounds for the effect of monetary policy on real output

endogenous oca analysis and the early euro experience some have argued that the endogenous responses to the formation of a currency area are so strong that one need not worry about optimum currency area conditions ex ante we argue that this is much too strong a conclusion we draw on a number of recent studies to evaluate the endogeneity experiences of the eurozone in three major areas trade flows business cycle synchronisation and structural reforms to improve labour and product market flexibility simple before and after comparisons are insufficient for analysis of endogeneity the experiences of non euro western european economies suggest that broader trends also had considerable influence on trade and business cycle patterns while trade rose substantially within the eurozone it also rose with and among other european economies we argue that political economy considerations tend to dampen the magnitude of endogeneity efforts on structural reforms and that meeting conditions for entry may be a more powerful mechanism in this than are subsequent endogenous responses we also discuss a number of areas for further research

misperceived job hazards and welfare abstract bayesian workers produce chemicals hazardously in one sector of a two sector economy having one safe sector adopting an expected ex post welfare perspective we show workers misperceptions of hazards entail a classic externality we characterise chemicals competitive monopoly and socially efficient outputs assuming workers receive identical wage accident compensation contracts under each the value of information which induces workers to place greater stress on firms safety records or sharpens their priors and extend the standard monopoly welfare loss index for sufficient conditions for monopoly to be preferred to competition in chemicals and for size ranking monopoly and efficient chemical outputs

workers of the world unite franchise extensions and the threat of revolution in europe 1820 1938 abstract we test the hypothesis that the extension of the voting franchise in europe was related to the threat of revolution we contend that international diffusion of regime contention and information about revolutionary events happening in neighboring countries generate the necessary variation in the perceived threat of revolution using two samples of european countries covering the period from 1820 to 1938 we find robust evidence which is consistent with the threat of revolution hypothesis we also find some evidence that war triggered suffrage reform

the degree of openness and the cost of fixing exchange rate abstract fixing the exchange rate entails costs in terms of suboptimal output if nominal wages are sticky it is generally assumed that these costs decrease with the degree of openness we demonstrate that they are either non monotonic or increasing in openness

trade creation and diversion revisited accounting for model uncertainty and natural trading partner effects summary the effect of preferential trade agreements ptas on trade flows is subject to model uncertainty stemming from the diverse and even contradictory effects suggested by the theoretical pta literature the existing empirical literature has produced remarkably disparate results and the wide variety of empirical approaches reflects the uncertainty about the correct set of explanatory variables that ought to be included in the analysis to account for the model uncertainty that surrounds the validity of the competing pta theories we introduce bayesian model averaging bma to the pta literature statistical theory shows that bma successfully incorporates model uncertainty in linear regression analysis by minimizing the mean squared error and by generating predictive distributions with optimal predictive performance once model uncertainty is addressed as part of the empirical strategy we find strong evidence of trade creation trade diversion and open bloc effects our results are robust to a range of alternative empirical specifications proposed by the recent pta literature copyright 2010 john wiley sons ltd

optimal multiperiod contracts and the gain from enduring relationships under private information informational asymmetries can play a key role in explaining the existence and nature of multiperiod contracts in an illustrative risk sharing model even relatively short two period contracts can be mutually beneficial if there is private information though one period contracts suffice otherwise further contracts which are pareto optimal relative to the environment and the information structure are defined and partially characterized an example illustrates how otherwise inefficient intertemporal tie ins can be used optimally to mitigate incentive problems the obvious borrowing lending schemes are not private information pareto optimal in these period by period actions are not sufficiently constrained discounting affects the form of the optimal contract but none of these qualitative conclusions

currency unions and the real exchange rate abstract when the transmission mechanisms are different across member states real exchange rate shocks affect currency unions aggregate inflation output and welfare at the regional level the impact of real exchange rate movements is larger in smaller countries

one money one market the effect of common currencies on trade currency unions their dramatic effect on international trade a gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade the panel data bilateral observations for five years during 1970 90 covering 186 countries includes 300 observations in which both countries use the same currency i find a large positive effect of a currency union on international trade and a small negative effect of exchange rate volatility even after controlling for a host of features including the endogenous nature of the exchange rate regime these effects statistically significant imply that two countries sharing the same currency trade three times as much as they would with different currencies currency unions like the european emu may thus lead to a large increase in international trade with all that that entails andrew rose

did the euro common currency increase or decrease business cycle synchronization for its member countries we use two variants of markov switching models to assess changes in output synchronization since the creation of the euro out of eight eurozone countries investigated only one the netherlands has synchronization increased since euro adoption supporting the endogenous optimal currency area argument of frankel and rose however in three other cases business cycle synchronization actually fell since the euro s creation thus the endogeneity of the optimal currency area criteria can go both ways adopting a common currency may increase synchronization for nations ready for a common currency but it can lower synchronization for nations that are far from synchronized before monetary unification

households willingness to pay for safeguarding security of natural gas supply in electricity generation abstract security of energy supply is a major issue for all eu member states due to europe s increasing dependence on imported fossil fuel sources and the continuous rise in energy demand the latter is of particular importance in electricity sector given the continuously increasing use of gas for electricity generation in order to properly tackle with the problem concerted actions are required by the eu member states in several levels i e legislative political etc nevertheless these actions will come at an additional cost paid by the society either through increased electricity bills or through public financing for energy security investments thus such policies should be justified on the basis of cost benefit analysis towards this direction it may be necessary to take into account non market costs and benefits i e the value that consumers place on interruptions avoided in order to explore households perceptions and willingness to pay for securing gas supply for electricity production an empirical study was conducted by means of the contingent valuation method the results indicate that consumers are willing to pay a premium on their electricity bills in order to internalize the external costs of electricity production in terms of energy security which are caused from imported fuels

how much intraregional exchange rate variability could a currency union remove the case of asean 3 abstract a multilateral currency union removes intraregional exchange rates but not the union rate the pre union intraregional exchange rate variability is thus latent a two step procedure is developed to measure this the measured variables are used to model inflation and intraregional trade growth of individual union members counterfactual simulations of the union impact are carried out using the resulting models application to asean 3 shows that the intraregional variability mainly consists of short run exchange rate shocks that the variability significantly affects inflation and intraregional trade of major asean 3 members and that a union would reduce inflation and promote trade regionwide

i can hear my neighbors fracking the effect of natural gas production on housing values in tarrant county tx abstract in this study we estimate the effect of hydraulically fractured natural gas wells on residential real estate prices we exploit variation in distance to nearby gas wells in home sale prices to estimate this effect in contrast to previous studies we focus on a relatively densely populated area a section of the dallas ft worth arlington urban area using a dataset of 127 556 observations from tarrant county texas over the period 2005 2011 we find robust evidence that increased proximity to a well leads to reduced home sale prices existence of wells within 3500 ft of a property reduces property values by approximately 1 5 3 we demonstrate that the reduction seems to be driven by unconventional rather than conventional wells and that well construction causes an added 1 2 reduction in home value

long run growth and volatility which source really matters the aim of the article is to analyse the relationship between long run growth and business cycle volatility in particular the main purpose of this article is to identify which source of volatility is most detrimental to growth using cross country data from 1970 to 2000 and several indicators of volatility such as inflation exchange rate government expenditure output and investment volatility this article shows that although all these measures of volatility are remarkably harmful for growth business cycle investment volatility is the main source that hampers long run growth this relation is robust to different measures of business cycle and to different sub samples of countries

the european union the euro and equity market integration abstract we use industry valuation differentials across european countries to study the impact of membership in the european union as well as the eurozone on both economic and financial integration in integrated markets discount rates and expected growth opportunities should be similar within one industry irrespective of the country implying narrowing valuation differentials as countries become more integrated our analysis of the 1990 2007 period shows that membership in the eu significantly lowered discount rate and expected earnings growth differentials across countries in contrast the adoption of the euro was not associated with increased integration our results do not change when the sample is extended to include the recent crisis period

north south and distance in the gravity model abstract it is generally assumed that distance in the gravity model strictly reflects frictions impeding bilateral trade however distances north south could also reflect differences in factor endowment that provide opportunities for profitable trade this paper investigates the hypothesis that if we control for distance in the ordinary sense differences north south promote international trade the hypothesis receives ample support moreover the significance of differences north south survives a battery of robustness tests concerning period distinctions between differences in latitude north north north south and south south and controls for other measures of differences in factor endowment such as differences in per capita output and differences in average temperature rainfall and seasonal range in temperature the impact of differences north south on bilateral trade has also been falling this decline in turn might be partly responsible for the weakening of the influence of distance that has been occurring since world war ii this last hypothesis receives confirmation as well finally the paper examines the impact of internal distance and remoteness on trade since both variables are country specific this is done by studying their impact on the country fixed effects themselves in the earlier estimates internal distance turns out to have a far greater impact than remoteness by an order of 10

on the trade impact of nominal exchange rate volatility what is the effect of nominal exchange rate variability on trade i argue that the methods conventionally used to answer this perennial question are plagued by a variety of sources of systematic bias i propose a novel approach that simultaneously addresses all of these biases and present new estimates from a broad sample of countries from 1970 to 1997 the estimates indicate that nominal exchange rate variability has no significant impact on trade flows

winners and losers from the uro abstract using the synthetic control method this paper estimates the effect of having joined the monetary union on the income per capita of six early adopters of the euro our estimates suggest that while the income per capita of belgium france germany and italy would have been higher without the euro that of ireland would have been considerably lower in contrast the netherlands would have been as well off without the euro we show that these estimates are not contingent on our choice of baseline control groups growth predictors and pre treatment period in addition we use the insights from the literature on the economic determinants of the costs and benefits of monetary unions to explain our estimates we find that early euro adopters with a business cycle more synchronized to that of the union and more open to intra union trade or migration lost less or gained more from the euro a key role in increasing post euro income losses of union members has been played by the integration of capital markets

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

benefits from mutual restraint in a multilateral monetary union summary we show that monetary union can enhance price stability for its member countries even if none of them has a long history of stable prices and independent monetary policy as is the case in a number of monetary union initiatives among developing countries the positive effect obtains because the opportunistic objectives of one country s policy makers are kept in check at the union level by other members with disparate objectives we calibrate the model to evaluate the proposed monetary union in the east african community the empirical results show that the mutual restraint on monetary policy is an important determinant of the expected benefit from an eac monetary union

random preferences towards bioenergy environmental externalities a case study of woody biomass based electricity in the southern united states article i nfo this paper contrasts alternate methodological approaches of investigating public preferences the random parameter logit rpl where tastes and preferences of respondents are assumed to be heterogeneous and the conditional logit cl approach where tastes and preferences remain fixed for individuals we conducted a choice experiment to assess preferences for woody biomass based electricity in arkansas florida and virginia reduction of co2 emissions and improvement of forest habitat by decreasing risk of wildfires and pest outbreaks were presented to respondents as attributes of using green electricity the results indicate that heterogeneous preferences might be a better fit for assessing preferences for green electricity all levels of both attributes were positive contributors to welfare but they were no statistically significant respondents expressed a positive mean marginal willingness to pay wtp for each attribute level the total wtp for green electricity per kilowatt hour was 0 049 kwh or 40 5 per capita year 1 when converted into future total annual expenditures

distance language religion and the law of one price evidence from canada and nigeria we examine the impact of physical distance language and religion on law of one price lop deviations across interwar canadian and modern nigerian cities the data comprise monthly average retail prices for narrowly defined goods collected by national statistical agencies we find that differences in the fraction of the city population sharing a common language and religion have a significant impact on lop deviations the impact of language differences is consistent with a recently developed theory in which both trade costs and differences in signal noise ratios contribute to lop deviations

exchange rate regimes and international trade evidence from the classical gold standard era in this paper we show that the spread of the classical gold standard in the late nineteenth century increased international trade flows this positive effect was compounded whenever a group of countries formed a monetary union applying the gravity model of trade to more than 1 100 country pairs during the 1870 1910 period we find that two countries on gold would trade 60 percent more with each other than with countries on a different monetary standard moreover a monetary union would more than double bilateral trade flows our findings are relevant for current discussions on alternative monetary arrangements for the twenty first century

using choice experiments to value the environment this paper we outline the choice experiment approach to environmental valuation this approach has its roots in lancaster s characteristics theory of value in random utility theory and in experimental design we show how marginal values for the attributes of environmental assets such as forests and rivers can be estimated from pair wise choices as well as the value of the environmental asset as a whole these choice pairs are designed so as to allow efficient statistical estimation of the underlying utility function and to minimise required sample size choice experiments have important advantages over other environmental valuation methods such as contingent valuation and travel cost type models although many design issues remain unresolved applications to environmental issues have so far been relatively limited we illustrate the use of choice experiments with reference to a recent uk study on public preferences for alternative forest landscapes this study allows us to perform a convergent validity test on the choice experiment estimates of willingness to pay

the internationalization of inventive activity a gravity model using patent data this paper discusses the extent and the determinants of the internationalization of european inventive activity between 1990 and 2004 using an innovative method to treat the information contained in the european patent office s patstat database the observed level of internationalization of inventive activities while being rather low has steadily increased over time the amount of collaboration between actors residing in different countries is assessed by means of a gravity model as it is familiar in the literature on international trade the amount of bilateral collaboration is positively affected by the presence of a common language and a common border and by the common participation in the european union participation in the euro zone is also found to have a marginally negative effect international collaboration is negatively affected by distance with estimated elasticities that are significantly smaller than the ones that characterize international trade contrary to the rumors about the death of distance this effect has become stronger in recent years

predation reputation and entry deterrence abstract economists often argue that predatory practices are irrational since there exist cheaper or more certain means to gain or maintain a monopoly our gametheoretic equilibrium analysis suggests that if a firm is threatened by several potential entrants then predation may be rational against early entrants even if it is costly when viewed in isolation because it yields a reputation which deters other entrants asymmetric information plays a crucial role in our analysis since it provides the rationale for entrants to base their expectations of the firm s future behavior on its past actions the analysis also suggests methods to treat general reputational phenomena

incentive effects of workers compensation insurance abstract this paper uses micro level data from the current population survey to estimate the determinants of participation in state workers compensation programs in the united states the principal finding is that higher workers compensation benefits are associated with greater participation in the workers compensation program after accounting for a variety of covariates in addition the waiting period is found to have a substantial negative effect on program participation finally time series estimates based on the cross sectional model show that the growth in workers compensation claims in the 1970s corresponds reasonably well with the growth in real benefits in this time period

the effects of a natural gas boom on employment and income in colorado texas and wyoming improvements in technology have made it profitable to tap unconventional gas reservoirs in relatively impermeable shale and sandstone deposits which are spread throughout the u s mostly in rural areas proponents of gas drilling point to the activity s local economic benefits yet no empirical studies have systematically documented the magnitude or distribution of economic gains i estimate these gains for counties in colorado texas and wyoming three states where natural gas production expanded substantially since the late 1990s i find that a large increase in the value of gas production caused modest increases in employment wage and salary income and median household income the results suggest that each million dollars in gas production created 2 35 jobs in the county of production which led to an annualized increase in employment that was 1 5 of the pre boom level for the average gas boom county comparisons show that ex ante estimates of the number of jobs created by developing the fayetteville and marcellus shale gas formations may have been too large

emu enlargement stabilization costs and insurance mechanisms this paper considers the determinants of the macroeconomic costs of joining emu for the new eu member sates and compares them with those of the emu members specifically we investigate the business cycle correlation between the candidate s economy and that of the euro area as a whole and the ability of insurance mechanisms and fiscal policies to smooth income fluctuations the results suggest that emu membership would not be costly for some countries cyprus hungary and malta but for other countries it could have relevant costs at least in the short run for some of these countries business cycles are not yet well synchronized with the euro area s business cycle and risk sharing mechanisms do not provide enough insurance against shocks

the nonlinear impact of currency unions on bilateral trade abstract most gravity model specifications assume that a currency union varies the level of bilateral trade between members by a constant proportion we demonstrate that a common currency also alters the slope of the relationship between bilateral trade and member country gdps

economic effects of currency unions we develop a new instrumental variable iv approach to estimate the effects of different exchange rate regimes on bilateral outcomes the basic idea is that the characteristics of the exchange rate between two countries are partially related to the independent decisions of these countries to peg explicitly or de facto to a third currency notably that of a main anchor this component of the exchange rate regime can be used as an iv in regressions of bilateral outcomes we apply the methodology to study the economic effects of currency unions the likelihood that two countries independently adopt the currency of the same anchor country is used as an instrument for whether they share a common currency we find that sharing a common currency enhances trade increases price comovements and decreases the comovement of real gross domestic product shocks

fixed exchange rates and trade abstract a classic argument for a fixed exchange rate is its promotion of trade empirical support for this however is mixed while one branch of research consistently shows a small negative effect of exchange rate volatility on trade another more recent branch presents evidence of a large positive impact of currency unions on trade this paper helps resolve this disconnect our results which use a new data based classification of fixed exchange rate regimes show a large significant effect of a fixed exchange rate on bilateral trade between a base country and a country that pegs to it these results suggest an economically relevant role for exchange rate regimes in trade determination since a significant amount of world trade is conducted between countries with fixed exchange rates

should i stay or should i go an agent based setup for a trading and monetary union abstract the recent history of the european union eu suggests the importance of studying the conditions under which two or more countries can benefit from becoming part of a union of course this depends both on the economic characteristics of the involved countries and on the scope of the union i e the level of integration of markets regulations and institutional bodies this study tackles the topic from the angle of agent based computational economics by designing an open economy model inspired from the eu where countries can be part of a trade and monetary union we find that for similar countries it is always beneficial to be a member of a union although a lack of mobility frictions can cause a divergence between the two countries weakening the overall union performance even if countries have different productivity the performance of the union is in general better than the performance of the isolated countries the exception is when productivity gap and labor mobility are both high in this case a strong migration within the union can create economic distortions exacerbating the gap between the member states stronger fiscal integration helps reducing inequality between countries increasing the sustainability of the monetary union

a new world order explaining the international diffusion of the gold standard 1870 1913 abstract the gold standard gradually became an international monetary regime after 1870 similarly some nations in the european union are waiting to adopt the euro while others have joined immediately what explains the timing of exchange rate regime adoption to find out the international diffusion of the gold standard is analyzed duration analysis shows that network externalities operating through trade channels the desire to decrease borrowing costs on international capital markets and the level of development matter some evidence shows that the level of exchange rate volatility or inflationist agricultural interests did not matter for the timing of adoption

currency unions and trade how large is the treatment effect currency unions and trade what can the data say the impact of a common currency on trade can be grossly mismeasured if countries that belong to currency unions are systematically different from those that do not and if the relationship between trade and its observable determinants is complex i argue that such complications are plausible and likely to distort the empirical results of a recent economic policy paper by andrew rose issue 30 2000 pp 7 45 using techniques designed to be robust in this situation i find that the effects of common currency on international trade are considerably less dramatic and much less precisely estimated torsten persson i have always maintained that the measured effect of a single currency on trade appears implausibly large but i am not convinced by torsten persson s diagnosis and proposed solution i apply a variety of estimation techniques to a new larger data set where many more instances of currency union creation and abandonment make it possible to rely on time series as well as cross sectional evidence the results are similar to my earlier ones the effect of a single currency on trade is large andrew rose

trade costs 1870 2000 what has driven trade booms and trade busts in the past century and a half was it changes in global output or in the costs of international trade to address this question we derive a micro founded measure of aggregate bilateral trade costs based on a standard model of trade in differentiated goods these trade costs gauge the difference between observed bilateral trade and frictionless trade in terms of an implied markup on retail prices of foreign goods thus we are able to estimate the combined magnitude of tariffs transportation costs and all other macroeconomic frictions that impede interna tional trade but that are inherently difficult to observe we use this measure to examine the growth of global trade between 1870 and 1913 its retreat from 1921 to 1939 and its subsequent rise from 1950 to 2000 we find that trade cost declines explain roughly 55 percent of the pre world war i trade boom and 33 percent of the post world war ii trade boom while a precipi tous rise in trade costs explains the entire inter

on the distribution of exchange rate regime treatment effects on international trade abstract this paper provides evidence of heterogeneous treatment effects on trade for six different types of exchange rate regime transitions utilizing data on 218 643 country pair year observations all together previous research mainly focused on the currency union effect on trade and widely assumed that country pairs with identical observable characteristics receive the same effect we test the hypothesis of a homogeneous treatment effect empirically and find substantive statistical support for the presence of effect heterogeneity moreover we characterize the probability distribution of effect heterogeneity among observationally equivalent country pairs by way of a random coefficients model we estimate selected features of the empirical distributions of the treatment effects for each of the six different types of exchange rate regime transitions under two different sets of assumptions about the probability distribution of effect heterogeneity our findings suggest that the immediate effects on trade from switching to an exchange rate regime different from the one in the outset have wide waists and exhibit large positive extreme values we estimate the probability of two countries to experience an immediate positive effect on the growth of bilateral trade due to the adoption of any new exchange rate regime tighter or not to be approximately one half

reputations for safety market performance and policy remedies this paper examines the provision of industrial safety in a competitive labor market under the assumption that it takes time for workers to learn about changes in safety levels at a firm it is shown that safety will in general be underprovided and that in some cases government enforced workmen s compensation can bring improvements the results hold even though in equilibrium all workers are perfectly informed about the level of safety prevailing at each firm and each is free to move to any firm he likes

the mirage of exchange rate regimes for emerging market countries this paper argues that much of the debate on choosing an exchange rate regime misses the boat it begins by discussing the standard theory of choice between exchange rate regimes and then explores the weaknesses in this theory especially when it is applied to emerging market economies it then discusses a range of institutional traits that might predispose a country to favor either fixed or floating rates and then turns to the converse question of whether the choice of exchange rate regime may favor the development of certain desirable institutional traits the conclusion from the analysis is that the choice of exchange rate regime is likely to be of second order importance to the development of good fiscal financial and monetary institutions in producing macroeconomic success in emerging market countries this suggests that less attention should be focused on the general question whether a floating or a fixed exchange rate is preferable and more on these deeper institutional arrangements a focus on institutional reforms rather than on the exchange rate regime may encourage emerging market countries to be healthier and less prone to the crises that we have seen in recent years

the myth of decoupling the decoupling hypothesis is the idea that business cycles in emerging market economies have become more independent from business cycles in advanced economies in recent years decoupling essentially amounts to a structural break in the degree of business cycle interdependence between the two groups of economies and it can be tested as such we develop an innovative measure of business cycle interdependence based on the euclidean distance available at the annual frequency which allows for a proper test for a structural break in a graphical setup we also make use of a standard econometric test both approaches point to the same conclusion there has been no decoupling in recent years if anything the degree of business cycle interdependence has become stronger

disaggregated trade and disaggregated currency unions a ranking of common currency effects andrew rose has long argued that a common currency has a large effect on increasing trade recently rose has called into question the reliability of this conclusion as new techniques have emerged for estimating gravity equations this article uses the sector specific gravity model developed by anderson and yotov 2010a to investigate if disaggregated trade can provide a reliable estimate of a common currency s effect disaggregating trade alone is insufficient to obtain a reliable estimate of a currency union regardless of econometric technique when the effect of a common currency on trade is uniform across all unions disaggregating the universe of currency unions with individual effects provides a reliable ranking of currency unions independent of estimation method by the effect that each union s currency has on increasing trade these rankings differ across sectors

has the euro changed the business cycle abstract in contrast to the notion that the exchange rate regime is non neutral there is little evidence that emu has systematically changed the european business cycle in fact we find the volatility of macroeconomic variables largely unchanged before and after the introduction of the euro exceptions are a strong decline in real exchange rate volatility and a considerable increase in cross country correlations to account for this finding we develop a two country business cycle model which is able to replicate key features of european data in particular the model correctly predicts a limited effect of emu on standard business cycles statistics however further analysis reveals that the euro has changed the nature of the cycle through its impact on the transmission mechanism cross country spillovers have become relatively more domestic shocks relatively less important in accounting for economic fluctuations under emu this explains why there is little change in unconditional volatilities

a comparison of stated preference methods for environmental valuation this paper presents an empirical comparison of contingent valuation cvm and choice experiments which are used to value environmental quality changes both of these methods require individuals to state their preferences for environmental qualities however choice experiments differ from cvm in that environmental attributes are varied in an experimental design which requires respondents to make repeated choices between bundles of attributes the empirical application involved the effect of environmental quality changes arising from forest management practices on recreational moose hunting values significant differences were found between the values derived from the two methods however detailed examination of the implied choice behaviour suggested that respondents ignored substitute recreation areas in the cvm question restricting the choice experiment model to consider only the one site where quality was varied resulted in welfare estimates similar to the cvm model this highlights the importance of substitutes in environmental valuation and suggests that choice experiments may be more appropriate than cvm in some cases
