black market exchange rate and the productivity bias hypothesis abstract previous studies that tested the productivity bias hypothesis employed the official nominal exchange rate in constructing the real rate hence in testing the productivity bias hypothesis in this paper we show that if official real exchange rate does not support the productivity bias hypothesis the real black market rate does this conjecture is tested by using data from chile colombia and costa rica

the great recession and the bulimia of us consumers deep causes and possible ways out this paper focuses on the apparent bulimia of us consumers and its role in the recent crisis we seek to show how various characteristics of american society and the us economy are related to this phenomenon we illustrate some structural features of the us economy and public policies that may have created a difference in terms of patterns of consumption and market participation between the usa and continental europe we then present some explanations of us hyperconsumerism put forward by psychologists and sociologists thus relating this phenomenon to the decline in subjective well being and social capital documented in the usa we also discuss how the negative endogenous growth paradigm may help to account for it finally we review the debate on the us policy agenda by underlining some weaknesses in the two politically more realistic options and by outlining a third policy strategy which is possibly preferable for people s long term well being

property rights externalities and resource degradation locating the tragedy abstract resource degradation in the third world is largely driven by the demands of farm households for fuelwood and land for agriculture since resources are often controlled through indigenous systems of property the tragedy of the commons has been used to explain resource degradation as a result private property is suggested as a solution to resource degradation a dynamic model capable of examining household incentives for resource use under private and common property is developed results of the model reject the conventional wisdom that gives rise to the presumed optimality of private individual property in natural resources and the correlated indictment of group management regimes

instability in short run adjustments to purchasing power parity results for selected latin american countries according to the theory of purchasing power parity ppp there is a tendency toward equalization of different countries price levels in common currency terms however even assuming that a long run ppp relationship exists its relevance for policy makers in less developed countries ldcs will depend not only on the average speed of adjustment toward this relationship but also on the variability of such short run adjustments we present evidence of extreme volatility in adjustments toward ppp for four latin american countries based on time varying parameter estimates of error correction models

environmental and economic effects of the copenhagen pledges and more ambitious emission reduction targets abstract a multi region multi sector dynamic computable general equilibrium model is applied to explore the economic and welfare effects of the pledges submitted by developed countries annex i countries and major developing non annex i countries for 2020 under the copenhagen accord in addition to analyzing scenarios reflecting the upper and lower bounds of the copenhagen pledges one additional policy scenario where annex i countries as a group reduce co 2 emissions by 30 in 2020 compared to 1990 levels and where major non annex i countries reduce co 2 emissions 15 below baseline is also analyzed economic effects are measured as changes in gdp compared to baseline and welfare effects are measured via the equivalent variation assuming that countries with emission targets may trade certificates average reductions in gdp for countries with targets range between 0 1 and 0 7 in 2020 for the policy scenarios while the gdp losses are larger for major non annex i countries with emission targets compared to annex i countries this is not the case for the changes in welfare with the exception of mexico the welfare losses for the major non annex i regions as a percentage of projected gdp in 2020 are lower than for the large annex i countries

how to beat the random walk an empirical model of real exchange rates abstract an econometric model is developed for all possible bilateral real exchange rates between the united states the united kingdom germany and japan for the period february 1977 to june 1987 we extend the standard dornbusch frankel type of models using an error correction approach with an observable macro economic determinant of the long run real exchange rate for the econometric analysis we develop an efficient estimator by pooling the data for all currencies contrary to previous empirical tests on the long run behaviour of real exchange rates we find a notable and significant mean reversion component

relative price determination in the medium run the influence of wages productivity and international prices this work explores three critical assumptions of the balassa samuelson productivity differential model for the short and medium run wage equalization competitive labor markets and purchasing power parity the data reveal violations in these assumptions for france germany japan the u k and the u s significant wage and unit labor cost differentials exist across industries and traded and nontraded sectors and these differentials do not diminish over time the findings are consistent with the presence of industry and or sectoral specific human capital

the solaria syndrome social capital in a growing hyper technological economy we develop a dynamic model to analyze the sources and the evolution of social participation and social capital in a growing economy characterized by exogenous technical progress starting from the assumption that the well being of agents basically depends on material and relational goods we show that the best case scenarios hold when technology and social capital both support just one of the two productions at the expenses of the other however trajectories are possible where technology and social interaction balance one another in fostering the growth of both the social and the private sector of the economy along such tracks technology may play a crucial role in supporting a socially sustainable economic growth

deviations from purchasing power parity in the long run this paper demonstrates that deviations from purchasing power parity reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible rate periods for a wide variety of countries and in both monthly and annual data since this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper proposes an alternative explanation which instead relies on financial arbitrage in bonds as the underlying mechanism this paper will demonstrate that deviations from purchasing power parity ppp reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible exchange rate periods for a wide variety of countries and in both monthly and annual data this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper therefore proposes an alternative explanation which does not presuppose free trade in goods but which instead relies on financial arbitrage in bonds as the underlying mechanism the major implication of the theory and the results is that ppp is as likely to be violated in the long as in the short run as an empirical matter deviations from ppp can be observed for most currencies at any instant see kravis et al 21 stockman 37 and genberg 15 among others these deviations are typically both cumulative and persistent the real exchange rate can remain on either side of parity for lengthy but variable time intervals of a year or more as a consequence the current consensus shared

purchasing power parity in the long run a cointegration approach this paper utilizes cointegration analysis to examine purchasing power parity relationships over a long time horizon the results indicate that the exchange rate is cointegrated strongly with the wholesale price index ratio and somewhat weakly with the consumer price index ratio the cointegrating coefficient between the exchange rate and the price ratio is close to one when cointegration is confirmed the hypothesis that the real exchange rate follows a random walk is rejected in most cases finally a new test for common trends finds no such common trends in exchange rates or price ratios copyright 1990 by ohio state university press

long run welfare under externalities in consumption leisure and production a case for happy degrowth vs unhappy growth in this paper we contribute to the debate on the relationship between growth and well being by examining an endogenous growth model where we allow for externalities in consumption leisure and production we analyze three regimes a decentralized economy where each household makes isolated choices without considering their external effects a planned economy where a myopic planner fails to recognize both leisure and consumption externalities but recognizes production externalities and a planned economy with a fully informed planner we first compare the balanced growth paths under the three regimes and then we numerically investigate the transition to the optimal balanced growth path we provide a number of findings first in a decentralized economy growth or labor or both are greater than in the regime with a fully informed planner and hence are sub optimal from a welfare standpoint second a myopic intervention which overlooks consumption and leisure externalities leads to more growth and labor than in both the decentralized and the fully informed regime third we provide a case for happy degrowth a transition to the optimal balanced growth path that is associated with downscaling of production a reduction in private consumption and an ongoing increase in leisure and well being

excess volatility of real exchange rates in the ems some evidence from structural vars this paper argues that the effectiveness of the exchange rate mechanism erm of the european monetary system ems should be gauged by its impact on the monetary component of real exchange rate variability nominal and real shocks are separated using a bivariate structural var applied to real exchange rate data of the six original member countries participating in the erm and a control group consisting of britain and the united states the findings suggest that monetary shocks have been an important source of real exchange rate variability and that the erm has been successful in reducing the incidence of monetary shocks across its member countries prior to the ems currency crises of 1992 93 while being less successful thereafter

a reexamination of balassa s productivity bias hypothesis rency by ri s the price level in country i by pi and the price level in the united states by pu s the ppp theory postulates that ri u s pi pu s many studies have tried to verify whether exchange rates follow the path outlined by the ppp equation the empirical results at best are inconclusive for example j a frenkel tested the ppp by drawing data from the 1970s and showed that the ppp failed on the other hand n davutyan and j pippenger criticized frenkel s work and reversed his conclusion 2 both studies used ordinary least squares and two stage least squares methods even recent studies that have used a relatively modern econometric technique cointegration analysis have mostly rejected the ppp 3 several reasons have been given in the literature for the failure of the ppp or deviation of the ppp based exchange rates from equilibrium exchange rates including lack of free trade existence of transaction costs existence of nontradables simultaneity problems different weights used in constructing different national price indexes money and asset prices and real factors or real variables among the real variables the productivity differential between two countries has received most of the attention in the literature if we denote the market determined equilibrium exchange rate by re and the ppp based rate by pi pu s following the literature we

the response of real exchange rates to various economic shocks substantial fluctuations in real exchange rates i e deviations from purchasing power parity ppp which closely mirror movements in nominal rates have been one of the most notable international economic events since the breakdown of the bretton woods system dornbusch s disequilibrium theory 9 which presumes different speeds of adjustment in assets and goods markets offers an explanation for temporary deviations from ppp only models assuming ppp as a long run relationship have not been successful in interpreting the movements of the real exchange rates although studies conducted for countries experiencing high or hyper inflation provide evidence favoring ppp 42 30 29 the empirical evidence on ppp for industrialized low inflation countries is not generally favorable 1 this is consistent with the view that ppp may hold better in high inflation countries where the disturbances to their economies are mostly monetary in origin 31 123 24 but ppp may not hold well when the real disturbances which change equilibrium relative prices dominate statistical evidence indicates that the real exchange rates of many countries are likely to be nonstationary or have long memory that is changes in the real values of many currencies tend to persist for very long period of time this persistence implies that fluctuations in the real exchange rates are largely due to long lasting effect of real disturbances after revealing that ppp does not hold as a long run concept for several exchange rates flynn and boucher 12 121 suggest that one possible explanation is that there are time varying real factors that are omitted from the ppp relationship there are several well established reasons why the real exchange rates may change in response to real disturbances in the first place permanent exogenous shocks to the tradable sector of the economy call for changes in competitiveness for instance a rise in the real price of oil will worsen the balance of trade position of a net oil importing country and therefore call for a real depreciation of the currency of the country in order to improve its competitive position 32 second when countries are growing at different rates productivity bias will typically result in

purchasing power parity and unit root tests using panel data abstract this paper reports the results of unit root tests for real exchange rates using a panel framework this panel approach provides greatly improved power compared to conventional univariate time series unit root tests we obtain evidence supporting ppp over the recent flexible exchange rate period for g 6 and oecd countries we show explicitly that failure to find such evidence in previous research was due to the low power of the tests

real exchange rate behavior abstract using random simulations with artificial data with identical sample characteristics to the long sample exchange rate data employed by lothian and taylor lothian j r and taylor m p 1996 the recent float from the perspective of the past two centuries journal of political economy 104 488 509 we show that standard unit root tests have extremely low power over sample sizes corresponding to the recent float the probability of rejecting the null hypothesis when it is false is extremely low with 20 years or even 50 years of data and only reaches an acceptable level over much longer spans

complying with the kyoto protocol under uncertainty taxes or tradable permits the kyoto protocol allocates tradable emission allowances aaus to developed countries but they are free to choose a set of policy instruments to comply with these targets we compare two different policy instruments a tax and purely domestic tradable permits for the european union the us and japan information on abatement costs and international permit price is imperfect and stems from nine global economic models for a country party to the protocol the benefit of emission reduction is that it can sell more or has to buy less aaus we show that in this context permits entail a slightly lower expected cost than a tax for the us and japan whereas both instruments yield an almost equal outcome for europe applying weitzman s framework prices vs quantities res 1974 in this context we show the importance of the positive correlation between costs and benefits technology shocks that lead to low abatement costs in one country generally lead to low abatement costs in other countries too thereby leading to a low international permit price in the true up period

environmental and social degradation as the engine of economic growth abstract in this paper a commonly owned resource an environmental or social asset and a private good are substitutes in consumption the households can buy the private good on the market while the resource is available for free the resource is renewable but its ability to regenerate declines with the level of aggregate production each single firm producing the private good has only a negligible impact on the resource but the impact caused by the entire population of firms is considerable in the face of a decrease in the stock of the resource households are induced to increase their participation in market activities in order to raise their income and buy more private goods hence each household contributes to a further increase in aggregate production thus causing additional damage to the resource s ability to regenerate and feeding the growth process given the presence of negative externalities multiple equilibrium paths are possible in this situation social conventions may guide individuals to coordinate expectations and behavior toward a particular steady state one can speculate that the dominance of cultural values favorable to a lifestyle based on a mix of high consumption and hard work leads the economy to converge on a pareto inferior steady state

coupling national and global models to explore policy impacts of ndcs abstract since the official submission of the national determined contributions ndcs under the paris agreement framework a set of studies attempted to assess the energy and economic impacts on ndcs by using large scale energy economy models both at the national and global level this paper presents a novel approach to quantify policy impacts of ndcs by combining a set of technology rich country level models for major economies with an economy wide global cge model the methodology enhances the credibility of global model based scenarios by complementing it with detailed representation of country level policy priorities and structural heterogeneities captured by national level models it also improves the consistency between national short to medium term policy plans with global long term climate objectives results indicate that energy efficiency improvements and increased penetration of res are the main contributors to emission reduction induced by ndcs the role of emission reduction options differentiates by country depending on national socio economic objectives energy resource endowment and climate policy ambition the paris pledges are found to be consistent with robust economic growth both in developed and in emerging economies ndcs result in a more labour intensive economy driven by res expansion while major clean energy manufacturers eu china have the potential to improve their balance of trade

international evidence on tradables and nontradables inflation abstract using 1970 1985 sectoral data for the oecd we find that inflation in nontradable goods exceeds inflation in tradables we identify a demand shift towards nontradables and faster growth of total factor productivity in the tradable goods sector as the prime causes of the differential inflation in addition disinflation attempts and the exchange rate regime appear to have exerted significant influence on the relative inflation rate

on the equilibrium yen dollar rate this paper presents a definition of the long run equilibrium exchange rate that emphasizes the role of supply factors in addition to the more traditional price differential variables using this definition we estimate the long run equilibrium yen dollar rate during the period of 1973 87 this calculation demonstrates that supply factors are in fact very important determinants of the long run movement of the exchange rate despite the central role the exchange rates play in the economy economists seem to doubt their own ability to explain let alone predict exchange rate movements the reason is that in many cases structural exchange rate equations do not significantly outperform various other models that do not appeal to economic theory such as the random walk see for example richard meese and kenneth rogoff 1983 while we also share this pessimism concerning our ability to forecast exchange rates in the short run intradaily to monthly or quarterly we argue that it is possible to reasonably explain if not predict long run movements the long run equilibrium rate is most often thought to be determined by purchasing power parity ppp which tends to focus only on price differentials medium run divergences of the exchange rate from the long run equilibrium are therefore commonly identified with fluctuations in the inflation adjusted real exchange rate this paper demonstrates however that the simple ppp is unsatisfactory because it emphasizes only the inflation differential in the more elaborated theory of purchasing power parity of course the potential importance of supply side real factors as critical determinants of the exchange rate has been well recognized see for example john m keynes 1923 rudiger dornbusch stanley fischer and paul a samuelson 1977 alan stockman 1980 nevertheless in empirical applications and policy discussions these supply side real factors have been curiously ignored to our knowledge an exception is david hsieh 1982 the main point of this paper is to show that these supply side factors actually have been very important determinants of the yen dollar rate over the period of 1973 to 1987

why real interest rates cost of capital and price earnings ratios vary across countries abstract this paper examines how productivity changes affect real rates of return and price earnings ratios in a small open economy the model provides conditions under which increased productivity in a country s traded goods sector causes prices of non traded goods to increase relative to the price of traded goods under these conditions real rates of interest decline and the production of certain non traded durable goods such as capital equipment and housing immediately increase this overconstruction has two effects first the increase in capital relative to labor in these sectors increases the marginal product of labor and hence immediately causes an increase in wages and the prices of non traded goods second an oversupply of capital goods and housing depresses their rental rates in the current period thereby increasing their price to rental ratios or equivalently their price earnings ratios

economic growth and emissions reconsidering the empirical basis of environmental kuznets curves abstract recent empirical research indicates that certain types of emissions follow an inverted u or environmental kuznets curve ekc as income grows this regularity has been interpreted as a possible de linking of economic growth and patterns of certain pollutants for developed economies in this paper the empirical basis of this result is investigated by considering some statistical particularities of the various ekc studies performed it is argued that the inverted u relationship between income and emissions estimated from panel data need not hold for specific individual countries over time based on insights from intensity of use analysis in resource economics an alternative growth model is specified and estimated for three types of emissions co2 nox and so2 in four countries netherlands uk usa and western germany it is found that the time patterns of these emissions correlate positively with economic growth and that emission reductions may have been achieved as a result of structural and technological changes in the economy sustainable growth is defined as the rate of economic growth that does not lead to growth in emissions its rate is calculated for each type of emission and country based on estimated parameter values the resulting indicators reflect a balance between the positive influence of growth and negative influence of structural change and technological progress on emission levels

systematic movements in real exchange rates in the g 5 evidence on theintegration of internal and external markets abstract many recent studies have documented the random behavior of real exchange rates this paper shows that real exchange rates defined for different sectors of an economy move closely together with one another even though each of the sectoral real exchange rates taken alone has a large random component the sectoral real exchange rates are tied together by internal price links due to factor mobility within each national economy any differences between real exchange rates which develop moreover can be explained almost entirely by productivity differentials at least in the long run this paper contrasts the strong ties which bind together prices from different sectors internally with ties that bind the prices of goods from the same sector internationally prices are shown to be much more highly correlated internally than externally because flexible exchange rates disrupt normal pricing relationships between goods from different countries

a quantitative reassessment of the purchasing power parity hypothesis evidence from norway and the united kingdom summary annual data from norway and the united kingdom from 1874 to 1971 are used to reassess the empirical performance of the purchasing power parity ppp doctrine the simple version of the ppp relationship is supported by the data only if different short run dynamics during a floating rate period 1914 1928 is allowed for two sets of factors were found to be important in amending the simple ppp model these were short run cyclical variables affecting the adjustment towards the ppp equilibrium relationship and long run structural factors such as productivity and terms of trade within this expanded model the proportionality between the exchange rate and relative price levels could not be rejected

real and nominal exchange rates in the long run an empirical investigation abstract this paper reports on econometric tests of the hypothesis that purchasing power parity holds as a long run relationship using data on eight industrialized countries during the flexible exchange rate period the empirical work proceeds by i testing whether nominal exchange rates and relative price levels are co integrated and ii conducting impulse response analysis of long run exchange rate and relative price level changes to explain the data keynesian models suggest that shocks during the estimation period were due principally to exogenous shifts in aggregate demand while equilibrium models suggest that monetary factors have been relatively more important

implications of the international reduction pledges on long term energy system changes and costs in china and india this paper analyses the impact of postponing global mitigation action on abatement costs and energy systems changes in china and india it compares energy system changes and mitigation costs from a global and two national energy system models under two global emission pathways with medium likelihood of meeting the 2 c target a least cost pathway and a pathway that postpones ambitious mitigation action starting from the copenhagen accord pledges both pathways have similar 2010 2050 cumulative greenhouse gas emissions the analysis shows that postponing mitigation action increases the lock in in less energy efficient technologies and results in much higher cumulative mitigation costs the models agree that carbon capture and storage ccs and nuclear energy are important mitigation technologies while the shares of biofuels and other renewables vary largely over the models differences between india and china with respect to the timing of emission reductions and the choice of mitigation measures relate to differences in projections of rapid economic change capital stock turnover and technological development furthermore depending on the way it is implemented climate policy could increase indoor air pollution but it is likely to provide synergies for energy security these relations should be taken into account when designing national climate policies

a note on the determinants of unexpected exchange rate movements abstract in this paper we study the relative importance of surprises in fundamentals in explaining unexpected exchange rate movements employing a unique survey dataset that contains matched exchange rate and interest rate expectations we are able to derive a number of interesting conclusions a variance decomposition of unexpected exchange rate movements into various components reveals that interest rate news is relatively unimportant but that changes in perceptions about risk premia and more importantly revisions of expectations with regard to future exchange rate levels are crucial in explaining unexpected exchange rate movements

the balassa samuelson hypothesis in the developed and developing countries revisited abstract this paper aims at examining the balassa samuelson bs hypothesis in 20 developed and 20 developing countries respectively given the cross sectional dependence and structural breaks we develop a new panel cointegration technique which allows for multiple heterogeneous unknown breaks and non stationary factors the empirical results show that the bs hypothesis holds in the developed countries implying that higher productivity growth leads to a real appreciation but they are cointegrated up to a number of cross sectional unobserved stochastic trends as factors are non stationary however we find little evidence to support the bs hypothesis in the developing countries and a further research is needed for the reason

productivity differentials the relative price of non tradables and real exchange rates abstract this paper reconciles the apparent contradiction between recent panel unit root tests of real exchange rates and the productivity differential model proposing an alternative view that explains the coexistence of such findings real exchange rates and the relative price of non tradables reflect the gradual adjustment of mean reverting and endogenously competing factors supply and demand shocks as well as traded goods arbitrage granger causality and variance decomposition results indicate substantial simultaneity and feedback effects between real exchange rates the relative price of non tradables and productivity differentials

sources of fluctuations in real and nominal exchange rates this paper attempts to distinguish empirically real versus nominal sources of fluctuations in real and nominal exchange rates the distinction is obtained by imposing the following restriction on the bivariate vector autoregression of real and nominal exchange rates over the current flexible rate period nominal shocks are required to have no permanent effect on the level of the real exchange rate given this identification scheme the author analyzes the dynamic effects and relative importance of real and nominal shocks with regards to exchange rates the findings indicate that real shocks dominate nominal shocks for both exchange rate series over short and long frequencies copyright 1992 by mit press

why are services cheaper in the poor countries in their important work on international comparisons of national incomes and of comparative price structure kravis heston and summers i982 p 8 have noted that services are much cheaper in the relative price structure of a typical poor country than in that of a rich country this phenonomen has been documented now fairly systematically by the data gathered under their guiding hand of the united nations international comparison icp which covers 34 countries table i reproduced from their work i982 and fig i based on rows 3 and ii 13 indeed show this tendencyfor the relationship between relative service prices and real per capita gdp in this kravis heston summers 34 country 6 group sample the tendency is strongly evident except for the intermediate groups iii and iv

transitory and permanent disturbances and the current account an empirical analysis in the intertemporal framework the intertemporal models of current account determination demonstrate that in the analysis of the current account balance of a country it is important to distinguish between transitory and permanent disturbances in income and relative prices this paper attempts to decompose the observed data on income and real exchange rate into transitory and permanent components and then uses the decomposed series to test the empirical validity of the predictions of the intertemporal models evidence from the united states and japan provide very limited support for the intertemporal models in terms of the effects of transitory and permanent changes in income on current account balance for both us and japan the study finds that permanent changes in real exchange rate have significant effects on the current account balance statistical tests find no evidence of hysteresis in the trading relations of the two countries

productivity bias hypothesis and the purchasing power parity a review article abstract productivity differentials among countries are said to be one of the major sources that contribute to the deviation of the purchasing power parity based exchange rate from the equilibrium rate hence the productivity bias hypothesis prior to last review article on the productivity bias hypothesis in 1976 almost all studies relied upon cross sectional regression analysis since then two groups of empirical studies have emerged while one group has employed time series data the other one has used panel data these two later groups have provided more support to the hypothesis than the earlier cross sectional studies this paper reviews and criticizes each group separately and provides tables that summarize main features of each study

happiness and health two paradoxes abstract this paper aims to establish systematic relationships between the two rapidly growing research streams on the socio economic determinants of happiness and health although they have been pursued quite independently by different communities of researchers empirical evidence points to very similar underlying causal mechanisms in particular in both cases per capita income seems to play a major role only up to a very low threshold beyond which relative income and other relational factors become crucial for happiness and health on the basis of these structural analogies we argue that a process of cross fertilisation between these two research streams would contribute to their development by clarifying the relationship between happiness health and their determinants finally we observe that the two literatures have converging policy implications measures meant to reduce poverty and inequality and invest in social and environmental capital may improve both health and happiness of the individuals

the j curve effect and us agricultural and industrial trade this paper examines the j curve hypothesis for us agricultural and manufactured goods using the shiller lag model the results support the j curve effect for agricultural goods but not for manufactured goods these findings explain why many studies in the literature fail to support the j curve phenomenon there are two explanations for these findings 1 the aggregation bias of data that combine both agricultural and manufactured goods and 2 the country under study is often an industrial nation like the us or japan with a high proportion of manufactured goods in both exports and imports

the term structure of currency carry trade risk premia we nd that average returns to currency carry trades decrease signicantly as the maturity of the foreign bonds increases because investment currencies tend to have small local bond term premia the downward term structure of carry trade risk premia is informative about the temporal nature of risks that investors face in currency markets we show that long maturity currency risk premia only depend on the domestic and foreign permanent components of the pricing kernels since transitory currency risk is automatically hedged by interest rate risk for long maturity bonds our

panel unit root tests of purchasing power parity for price indices abstract this paper adopts four panel unit root tests to evaluate ppp over the floating period for six different price indices results generally support ppp albeit the speeds of adjustment differ considerably between price indices and test procedures the degree of contemporaneous and serial correlation as well as heterogeneity of the series in the panel affect stationarity and the speed of mean reversion

assessment of copenhagen pledges with long term implications abstract this study first evaluates the pledges under the copenhagen accord using the dne21 model our estimates for the 2020 pledges fall collectively within the range of 46 700 49 100 mt co 2 eq our study also finds the efforts arising from the current 2020 pledges have wide ranging implications in terms of mitigation costs and types of actions based on this analysis we seek to place the copenhagen pledges in a long term context putting focus on costs and feasibility we set up a carbon prices convergence scenario assuming that all countries start from the copenhagen commitments and gradually undertake their own individual efforts in accordance with the convergence of carbon prices toward a uniform price in 2050 despite soaring carbon prices in most countries total costs as share of gdp show modest increase ranging mostly between 0 and 0 4 we also find that there does not seem to be much difference in the degree of burden between developed and major developing countries under this scenario since the challenge of climate change will require significant reductions in ghg emissions in the coming decades we need to make long lasting efforts getting on the right track toward the ultimate goal of stabilizing ghgs

policy convergence the exchange rate mechanism and the misalignment of exchange rates some tests of purchasing power parity and generalized purchasing power parity the paper focuses on the convergence issues and the long run credibility of the european monetary system ems and more specifically on the evaluation of the effectiveness of the exchange rate mechanism erm in generating a stabilizing effect on real exchange rates across member countries for this purpose we execute some tests of long run purchasing power parity ppp for an erm group and a non erm group of countries using both the engle and granger procedure and the more powerful johansen cointegration technique we also execute a test of generalized ppp exploiting an idea developed by enders and hurn testing for ppp in a multicountry setting may be a useful methodology to identify the optimal currency area suggested by the data generation process on the basis of the reported homogeneity of real exchange rate behaviour of the countries considered

do relative prices of non traded goods determine long run real exchange rates in this paper the long run assumptions of so called equilibrium models of real exchange rates are investigated the assumption of purchasing power parity for tradable goods common to this class of models implies that the real exchange rate is a function of the relative prices of nontraded goods in the two countries while purchasing power parity for tradable goods is not directly testable exploitation of wholesale and consumer prices allows for direct estimation of the reduced form cointegration tests are performed for twenty one bilateral relationships while much of the evidence is consistent with the predictions of equilibrium models results are far from conclusive

female labour force participation and economic growth in the south mediterranean countries abstract we investigate the relationship between female labour force participation and economic growth in the south mediterranean countries with a two step methodology of econometric exercise and general equilibrium modelling econometric estimations on female labour participation confirm the u shaped function and the presence of region specific barriers estimations have been employed in a satellite manner to a general equilibrium model for the simulation of i changes in female labour force participation as a result of income developments and ii lowering of region specific barriers to female labour force participation the results suggest that while the first may lead to marginally lower economic growth the second may have a considerable positive impact on growth

an empirical inquiry into the nature of the forward exchange rate bias abstract this paper tests whether anticipated real exchange rate movements fully account for the systematic time varying discrepancies between forward and future spot exchange rates the data do not reject this hypothesis the results demonstrate that 1 real exchange rate changes are predictable 2 anticipated real exchange rate changes are reflected in the forward bias and 3 information available at the signing of the forward contract is useless in forecasting differences between forward and future spot prices beyond the information s ability to predict real exchange rate changes the results emphasize the importance of real exchange rates in international asset pricing

impact of the kyoto protocol on the iberian electricity market a scenario analysis this paper presents an assessment of the impact of the kyoto protocol on the iberian electricity market during two periods the first phase 2005 2007 and the second phase 2008 2012 a market equilibrium model is used in order to analyze different conditions faced by generation companies scenarios involving co2 emission prices hydro conditions demand fuel prices and renewable generation are considered this valuation will show the significance of co2 emission prices as regards spanish and portuguese electricity prices generation mix utilities profits and the total co2 emissions furthermore the results will illustrate how energy policies implemented by regulators are critical for spain and portugal in order to mitigate the negative impact of the kyoto protocol in conclusion the iberian electricity system will not be able to reach the kyoto targets except in very favorable conditions co2 emission prices over 15 ton and the implementation of very efficient energy policies

foreign direct investments environmental externalities and capital segmentation in a rural economy this paper examines the possible effects of external investment inflows on the development of local rural economies taking into account two recurrent features of many developing countries capital market segmentation and environmental externalities to investigate this issue we examine a model with two sectors the local sector and the external sector physical capital accumulation in the latter sector is driven by foreign direct investments while in the former sector it follows a solow type accumulation mechanism we assume that the production activity of the external sector damages the environment while the local sector relies on natural resources in this context we give the conditions under which capital inflows can promote diversification of host economy while improving welfare of local populations if these conditions are not satisfied external investments fuel a welfare reducing process for the local community and a self enforcing growth of the external sector at the expense of the local one

cointegration tests of purchasing power parity the case of swiss exchange rates abstract this paper tests purchasing power parity ppp as a long run equilibrium condition by examining the long run relationshiop between exchange rates and wholesale price indices using cointegration tests this paper avoids some of the problems of previous cointegration tests of ppp by using more precise data pretests and by not imposing a priori restrictions upon the cointegrating vector of the nine combinations of swiss exchange rates and price indices examined cointegration is detected in seven cases thus supporting ppp as a long run equilibrium jel f31 c32

real exchange rates ppp and the relative price of nontraded goods the purchasing power parity hypothesis ppp states that nominal exchange rates move with differences in relative prices between economies the theory has received considerable attention in the economic literature since cassell 6 and is the foundation of many long run theoretical hypotheses in international finance yet its empirical validity remains in question many tests of ppp focus on the stationarity of the real exchange rate the nominal exchange rate adjusted for changes in price levels between economies if domestic and foreign price levels and the nominal exchange rate are integrated then cointegration between these variables implies the existence of both a long run equilibrium relationship and ppp the residual the real exchange rate then follows a stationary process the paper uses the multivariate cointegration methodology of johansen 16 and johansen and juselius 17 18 to examine the source of real exchange rate nonstationarity is the nonstationarity due to shifts in the domestic and foreign price of nontradeables or productivity differentials between traded and nontraded sectors or is the nonstationarity a possible outcome of difficulties in intercountry comparisons of prices movements associated with construction of these price indices most research finds the real exchange rate follows a nonstationary process due to the presence of a unit root 8 12 1 9 19 27 however the existence of a variable trend in the real exchange rate does not imply the absence of a long run relationship between relative prices levels and nominal exchange rates for two reasons first a long run relationship between price levels and nominal exchange rates may exist but not the one for one relationship implicit in the calculation of real exchange rates due to measurement differences in the construction of price indices between economies second ppp violations may occur due to the presence of permanent productivity innovations which affect the relative price of nontradeables if these shocks are not represented by measurable variables a cointegrating relationship will not exist the paper constructs traded and nontraded gdp price indices and productivity rates for 14 oecd economies and tests 1 if the variable trend the nonstationary process in the real exchange rate is due to permanent innovations in relative price of domestic and foreign nontradeables 2 if long run ppp violations are due to permanent movements in the relative price of nontradeables 3 if the nonstationarity in the real exchange rate is due to permanent innovations in domestic and foreign productivity differentials between the traded and nontraded sectors 4 if the variable trend in the relative price of nontradeables is due to permanent innovations in productivity between sectors lastly the paper constructs a cointegrating error correction model

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

the overvaluation of renminbi undervaluation we evaluate whether the renminbi rmb is misaligned relying upon conventional statistical methods of inference a framework built around the relationship between relative price and relative output levels is used we find that once sampling uncertainty and serial correlation are accounted for there is little statistical evidence that the rmb is undervalued even though the point estimates usually indicate economically significant misalignment the result is robust to various choices of country samples and sample periods as well as to the inclusion of control variables

the determination of the real exchange rate the productivity approach abstract this paper explains deviations of exchange rates from purchasing power parity with the differences between countries of the relative growth rates of labor productivity between traded and nontraded sectors two cases are considered germany and japan versus their respective major trading partners the results show that the time series methodology yields a more favorable confirmation of the productivity differential model than the cross section regressions in the literature

the economic effects of climate change greenhouse gas emissions are fundamental both to the world s energy system and to its food production the production of co2 the predominant gas implicated in climate change is intrinsic to fossil fuel combustion specifically thermal energy is generated by breaking the chemical bonds in the carbohydrates oil coal and natural gas and oxidizing the components to co2 and h2o one cannot have cheap energy without carbon dioxide emissions similarly methane ch4 emissions an important greenhouse gas in its own right are necessary to prevent the build up of hydrogen in anaerobic digestion and decomposition one cannot have beef mutton dairy or rice without methane emissions climate change is the mother of all externalities larger more complex and more uncertain than any other environmental problem the sources of greenhouse gas emissions are more diffuse than any other environmental problem every company every farm every household emits some greenhouse gases the effects are similarly pervasive weather affects agriculture energy use health and many aspects of nature which in turn affects everything and everyone the causes and consequences of climate change are very diverse and those in low income countries who contribute least to climate change are most vulnerable to its effects climate change is also a long term problem some greenhouse gases have an atmospheric life time measured in tens of thousands of years the quantities of emissions involved are enormous in 2000 carbon dioxide emissions alone and excluding land use change were 24 billion metric tons of carbon dioxide tco2

the eu decarbonisation roadmap 2050 what way to walk we carry out a detailed cge computable general equilibrium analysis of the eu decarbonisation roadmap 2050 on a macroeconomic and on a sectoral level herein we study a reference scenario that implements existing eu policies as well as 3 unilateral and 3 global climate action scenarios we identify global climate action with international emissions trading and the full equalization of co2 prices across all eu sectors as a reasonable policy option to avoid additional costs of the decarbonisation roadmap to a large extent this policy option may include cdm clean development mechanism in the sense of where flexibility in an extended form if there are countries without emissions caps moreover we identify diverse sectoral effects in terms of output investment emissions and international competitiveness we conclude that the successful realization of the eu decarbonisation roadmap probably requires a wise and joint consideration of technology policy design and sectoral aspects

long run purchasing power parity during the recent float abstract this paper examines the relevance of long run purchasing power parity ppp which allows for measurement errors during the recent floating exchange rate period previous empirical studies generally fail to find support for long run ppp over this period in this paper in this paper the cointegration property of exchange rates and prices is examined using maximum likelihood procedure and we find significant evidence favorable to long run ppp further tests for symmetry and proportionality indicate that these two conditions are not generally with the data the results support the hypothesis of long run ppp with measurement errors in prices

beyond the purchasing power parity testing for cointegration and causality between exchange rates prices and interest rates abstract this paper reexamines the causality between the dollar and the yen in a multivariate framework with the aid of cointegration and error correcting modeling for the 1951 94 period the phillips perron tests and johansen s tests are performed while causality from interest rates to exchange rates is found in the short run no causality between prices and exchange rates is found in the short run however causality is found running from relative prices to exchange rates along with interest rates between the u s and japan in the long run which supports the long run ppp hypothesis

environmental degradation as engine of undesirable economic growth via self protection consumption choices we analyze growth dynamics in an economy where the well being of economic agents depends on three goods leisure a free access environmental good and a private good that can be consumed as a substitute for the environmental resource the processes of production and consumption of the private good by each agent impose negative externalities on other agents through the depletion of the environmental good this paper shows that in such context the existence of private substitutes for environmental goods may fuel an undesirable economic growth process this process is driven by the continuous increase in agents needs for private consumption generated by the progressive reduction in free consumption of the environmental good

on the deviations from purchasing power parity the case of the ringgit effective exchange rate the paper investigates the extent to which the ringgit exchange rate converges on its purchasing power parity level in the long run using the cointegration and variance ratio tests the results indicate that shifts in the real exchange rate are dominated by permanent stochastic shocks which prevent it from reverting to its ppp base level further analysis indicates that low frequency movements in the relative price of tradable goods and the external terms of trade cannot explain the long run swing in the real exchange rate

nontradable goods prices and per caita income an application to regional korean data pooled time series cross sectional regional data for korea over the period 1985 1991 are used to investigate points which emerged from the united nations international comparison project the results based on a regional analysis are opposite to those of the icp the prices of services do not increase more rapidly in fast growing than in slow growing regions this regional analysis provides constradictory evidence to the widely recognized stylized fact that the prices of nontradables increase with real per capital income by a larger margin than the prices of tradables increase

government expenditure real exchange rate and the decline of the manufacturing sector some empirical evidence abstract i show that the increase in government expenditure in european countries during the 1970s raise the relative price of non traded goods this relative price movement may explain why the share of manufacturing in private sector value added declined in those countries

cointegration and tests of purchasing power parity nonstationarity in the levels of spot exchange rates and domestic and foreign price indices makes the use of conventional tests of the absolute version of purchasing power parity ppp inappropriate if ppp is true inter country commodity arbitrage ensures that deviations from a linear combination of spot exchange rates and domestic and foreign price levels should be stationary under these conditions exchange rates and price levels should form a cointegrated system we find the null hypothesis of no cointegration cannot be rejected for all five countries thus violating the long run absolute version of ppp

the purchasing power parity debate originally propounded by the 16th century scholars of the university of salamanca the concept of purchasing power parity ppp was revived in the interwar period in the context of the debate concerning the appropriate level at which to re establish international exchange rate parities broadly accepted as a long run equilibrium condition in the post war period it first was advocated as a short run equilibrium by many international economists in the first few years following the breakdown of the bretton woods system in the early 1970s and then increasingly came under attack on both theoretical and empirical grounds from the late 1970s to the mid 1990s accordingly over the last three decades a large literature has built up that examines how much the data deviated from theory and the fruits of this research have provided a deeper understanding of how well ppp applies in both the short run and the long run since the mid 1990s larger datasets and nonlinear econometric methods in particular have improved estimation as deviations narrowed between real exchange rates and ppp so did the gap narrow between theory and data and some degree of confidence in long run ppp began to emerge again in this respect the idea of long run ppp now enjoys perhaps its strongest support in more than 30 years a distinct reversion in economic thought

measuring exchange rate misalignment inflation differentials and domestic relative prices abstract empirical studies of exchange rate misalignment generally use crosscountry differences in overall inflation as proxy measures for a country s real exchange rate rer this paper shows that using such differential inflation proxies introduces two systematic biases in model results understatement of rer movements and a spurious trend towards depreciation these biases can be corrected only with disaggregated data on domestic relative prices of tradable and nontradable products using a standard model with disaggregated data for zimbabwe it is found that proxy based results understate misalignment by almost 25 and exaggerate depreciation by 4 per year

searching for stationarity purchasing power parity under the current float abstract using panel data methods we investigate long run purchasing power parity by testing for unit roots in real exchange rates of industrial countries under the current float the evidence against the unit root hypothesis is stronger for larger than for smaller panels for monthly than for quarterly data and when the german mark rather than the united states dollar is used as the base currency while we find that accounting for serial correlation considerably weakens the evidence against the unit root null the results as a whole are consistent with long run purchasing power parity

industrial output restriction and the kyoto protocol an input output approach with application to canada the objective of this paper is to assess the economic impacts of reducing greenhouse gas emissions by decreasing industrial output in canada to a level that will meet the target set out in the kyoto protocol the study uses an ecological economic input output model combining economic components valued in monetary terms with ecologic components ghg emissions expressed in physical terms economic and greenhouse gas emissions data for canada are computed in the same sectoral disaggregation three policy scenarios are considered the first one uses the direct emission coefficients to allocate the reduction in industrial output while the other two use the direct plus indirect emission coefficients in the first two scenarios the reduction in industrial sector output is allocated uniformly across sectors while it is allocated to the 12 largest emitting industries in the last one the estimated impacts indicate that the results vary with the different allocation methods the third policy scenario allocation to the 12 largest emitting sectors is the most cost effective of the three as the impacts of the kyoto protocol reduces gross domestic product by 3 1 compared to 24 and 8 1 in the first two scenarios computed economic costs should be considered as upper bounds because the model assumes immediate adjustment to the kyoto protocol and because flexibility mechanisms are not incorporated the resulting upper bound impact of the third scenario may seem to contradict those who claim that the kyoto protocol would place an unbearable burden on the canadian economy c 2008 elsevier b v all rights reserved

managing local commons in developing economies an institutional approach abstract resource degradation has a profound influence on food sustainability of developing economies the breakdown of traditional institutions enhanced this problem and needs an institutional approach many of the traditional policies like regulation and taxation have failed to deliver the required benefits this paper uses principal agency theory to develop a criterion for incentive design three incentive structures are developed based on contractual agreements and restructured property rights that use the criterion two case studies were used to discuss the new institutional arrangement some practical implications of the mechanisms designed include linearity of incentive rules development of an effort reward matrix and gradual reinstatement of local governance
