financial liberalization urban unemployment and welfare some implications of the artificial low interest rate and the high wage rate policies in ldcs abstract this paper investigates how the low interest rate policy in the commercial banking sector affects the urban unemployment in a small open harris todaro model the rate of urban unemployment unambiguously declines the volume of it shrinks if the rural to urban employment rate and the urban unemployment rate are sufficiently high relative to the wage elasticity of agricultural labor demand the national income increases if agriculture is dominant in the domestic production in such an economy the financial liberalization advocated by the mckinnon shaw school may aggravate the welfare even if it eliminates the financial repression

tariffs capital controls and equilibrium real exchange rates a general equilibrium intertemporal model with optimizing consumers and producers is developed to analyse how the equilibrium real exchange rate rer reacts to changes in the degree of restrictions to intra and intertemporal trade in particular the effects of changes in the level of import tariffs and of changes in taxes on foreign borrowing on the path of equilibrium rers are investigated in the case of import tariffs both temporary and anticipated changes are considered it is shown that in this intertemporal framework equilibrium real exchange rates can exhibit interesting and convoluted behaviour in particular results that contradict the traditional wisdom can be obtained a number of extensions are also discussed tarifs douaniers controles sur les flux de capitaux et taux de change reels d equilibre l auteur developpe un moddle d equilibre general inter temporel dans lequel consom mateurs et producteurs optimisent pour analyser les reactions du taux de change reel d equilibre aux changements dans le degre de restriction du commerce intra et inter temporel en particulier l auteur analyse les effets de changements dans le niveau des tarifs douaniers sur les importations et des taxes sur les emprunts a l etranger sur le sentier d equilibre du taux de change reel dans le cas des tarifs a l importation l auteur examine a la fois les changements temporaires et anticipes on montre que dans ce cadre intertemporel le comportement des taux de change reels d equilibre est interessant et contournm les resultats obtenus contredisent ceux suggeres par la sagesse conventionnelle l auteur discute aussi un certain nombre d extensions de ces resultats

tariffs real exchange rates and the trade balance in a two country world abstract an intertemporal model of a two country world in which optimizing agents consume three goods importables exportables and nontradables is developed to investigate a tariffs effects on real interest rates real exchange rates and the trade balance real interest rates and real exchange rates are shown to move asymmetrically across countries in response to a temporary tariff we also show that in contrast to the findings of two tradable good models a temporary tariff may actually worsen the trade balance of both deficit and surplus countries even when there are no cross country differences in tastes

estimating the environment kuznets curve hypothesis evidence from latin america and the caribbean countries this study explores the effect of economic growth gdp renewable energy consumption re and financial development fd on co2 emission co2 in latin america and caribbean countries to achieve this goal a panel co2 model was built over the period 1980 2010 the kao cointegration test results revealed that the variables are cointegrated the fully modified ols fmols results indicated an inverted u shape relationship between co2 and gdp thus confirming the environmental kuznets curve hypothesis furthermore fmols results also revealed that fd can improve environmental quality by its negative long run effect on co2 however re has no long run effect on co2 indicating that the re does not contribute to co2 reduction the vecm granger causality results revealed feedback causality between gdp re fd and co2 in both short and long run additionally granger causality results also revealed that re gdp and fd can be a good solution to reduce environmental damage since they have a causal effect on co2 this study shows the investigated countries should increase their banking loans on green energy energy efficiency and energy saving projects to reduce environmental damage in addition the above recommendation can increase the contribution of renewable energy in reducing environmental damage

the welfare effects of trade and capital market liberalization treatise on the welfare effects of trade and capital market liberalization consquenses of the capital account liberalization in the presence of trade restrictions specifies on the liberalization of trade in the presence of foreign borrowing constraints proves superiority of gradual liberalization of trade to an abrupt liberalization

anticipated protectionist policies real exchange rates and the current account the case of rigid wages abstract in this paper we develop a general equilibrium model of an economy with short run unemployment to analyze how anticipated protectionist policies affect real exchange rates the current account and aggregate employment we find that a key transmission channel is the change in current employment induced by future changes in tariffs we show that the direction and magnitude of this effect will depend on relative factor intensities and on real exchange rate behavior if a future tariff generated a current real exchange rate appreciation and if nontradables are labor intensive the anticipation of protectionist policies will generate an increase in current employment

trade taxes and the current account abstract we show that under some conditions a temporary import tariff improves the current account whereas a temporary export tax deteriorates it permanent import tariffs and export taxes have an identical although ambiguous effect on the current account

response of the equilibrium real exchange rate to real disturbances in developing countries abstract using a simple dependent economy framework this paper outlines the links between the equilibrium real exchange rate and some of its fundamental exogenous determinants mainly terms of trade movements and commercial policy changes drawing on existing studies of trade flows in developing countries it is possible to derive plausible quantitative ranges for the response of the equilibrium real exchange rate to both external and policy induced shocks the results should be particularly relevant in designing real exchange rate targets and rules that allow for movements in the equilibrium real exchange rate in response to various shocks

tariffs employment and the current account real wage resistance and the macroeconomics of protectionism using a standard complete specialization model of a small open economy within a rigorous intertemporal optimization framework and with contract based wage rigidity we show that permanent tariffs lead to a current account deterioration and a fall in employment contradicting most of the literature on macroeconomic effects of import tariffs the crucial factor in this complete reversal of standard results is the impact of tariffs on domestic real product wages via wage indexation temporary tariffs will have less of a negative impact on the ca or potentially even a positive impact because they increase the consumption rate of interest the terms at which future consumption can be traded for current consumption and so increase private savings extensions towards incorporating a more general production structure investment and the use of tariff revenues to provide wage subsidies are presented this abstract was borrowed from another version of this item

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

tariffs and the current account the role of initial distortions from an initial position of laissez faire temporary tariffs have been shown to improve the current account however if tariffs are initially positive as in many actual economies temporary tariffs will magnify an existing distortion and therefore lower real income during protectionist periods optimizing agents may wish to smooth the path of consumption relative to income by foreign borrowing if the intertemporal elasticity of substitution is sufficiently low temporary tariffs may actually worsen the current account

testing the prebisch singer hypothesis since 1650 evidence from panel techniques that allow for multiple breaks abstract in this paper we re examine two important aspects of the dynamics of relative primary commodity prices namely the secular trend and the short run volatility to do so we employ 25 series some of them starting as far back as 1650 and powerful panel data stationarity tests that allow for endogenous multiple structural breaks results show that all the series are stationary after allowing for endogenous multiple breaks test results on the prebisch singer hypothesis which states that relative commodity prices follow a downward secular trend are mixed but with a majority of series showing negative trends we also make a first attempt at identifying the potential drivers of the structural breaks we end by investigating the dynamics of the volatility of the 25 relative primary commodity prices also allowing for endogenous multiple breaks we describe the often time varying volatility in commodity prices and show that it has increased in recent years

tariffs and exchange rate dynamics redux abstract this paper builds a two country intertemporal macroeconomic model similar to one developed recently by obstfeld and rogoff imperfectly competitive producer consumers maximize an intertemporal utility function with consumption real money balances and output as arguments we use the framework to examine both the short run and steady state effects of the imposition of a tariff in one of the countries this results in a fall in the tariff imposer s output in both the steady state and in the short run a small tariff may make a country worse off contrary to the usual result under perfect competition spillover effects are also considered

economic growth energy consumption financial development international trade and co2 emissions in indonesia this study examines the linkages among economic growth energy consumption financial development trade openness and co2 emissions over the period of 1975q1 2011q4 in the case of indonesia the stationary analysis is performed by using zivot andrews structural break unit root test and the ardl bounds testing approach for a long run relationship between the series in the presence of structural breaks the causal relation between the concerned variable is examined by the vecm granger causality technique and robustness of causal analysis is tested by innovative accounting approach iaa our results confirm that the variables are cointegrated it means that the long run relationship exists in the presence of structural break stemming in the series the empirical findings indicate that economic growth and energy consumption increases co2 emissions while financial development and trade openness compact it the vecm causality analysis has shown the feedback hypothesis between energy consumption and co2 emissions economic growth and co2 emissions are also interrelated i e bidirectional causality financial development granger causes co2 emissions the study opens up a new policy insights to control the environment from degradation by using energy efficient technologies financial development and trade openness can also play their role in improving the environmental quality

productivity shocks non traded goods and optimal capital accumulation this paper considers the interaction of saving and investment in determining the current account for a small open economy subjected to productivity shocks by emphasizing the distinction between traded and non traded goods the analysis highlights the crucial role of the real exchange rate in macroeconomic adjustment our results demonstrate the importance of intertemporal substitution for determining the response of investment to anticipated productivity disturbances we also show how the correlation of movements in saving and investment following an anticipated disturbance depends critically on relative sectoral factor intensities

exploring the bi directional long run relationship between energy consumption and life quality abstract this study aims at investigating the bi directional long run relationship for the period of 1990 2009 between energy consumption and life quality in 198 countries categorized by income level to achieve this goal the canonical cointegrating regression ccr was utilized the results revealed that energy consumption improves the life quality of 70 of the countries despite their different incomes the study s results unlike all other previous studies also revealed that the life quality indicators also increase energy consumption a phenomenon that appears to be true in 65 of the countries despite the fact that energy consumption plays an important role in achieving a better life quality the world still depends on fossil fuels which represent 81 of total energy consumption therefore it is suggested that these countries should rationalize their fossil fuel energy consumption by increasing the role of renewable energy and increasing their energy saving to improve life quality without causing any damage to the environment

electricity consumption and economic growth in nigeria a revisit of the energy growth debate abstract this paper examines the dynamic causal linkages between electricity consumption and economic growth in nigeria within a trivariate vecm for the period 1971 2011 the paper obviates the variable omission bias and the use of cross sectional techniques that characterise most existing studies the results show that there is a distinct causal flow from electricity consumption to economic growth both in the short run and in the long run this finding supports the electricity led growth hypothesis that has been conjectured in the literature the paper urges policy makers in nigeria to implement policies which enhance the generation and consumption of electricity in order to engineer economic growth appropriate monetary policies must also be put in place in order to moderate inflation thus enhancing growth

international factor mobility minimum wage rates and factor price equalization a synthesis this paper examines the behavior of a small open economy facing perfectly elastic supply curves for some of its productive factors in particular the paper derives some comparative statics properties of such economies compares them with the properties of otherwise identical economies in which all factor prices are determined endogenously and investigates the relationship between factor price rigidities factor price equalization and the pattern of specialization among the new results which are proved it is shown that as more and more factor price rigidities are imposed on an economy it comes closer to a state of factor price equalization

trade taxes and economic welfare abstract for a small country with no domestic distortions trade taxes are generally viewed as welfare reducing this note shows that in certain cases a temporary trade tax may raise welfare in the present although it must lower welfare over the entire planning horizon

temporary import quota and the current account this paper studies the effects of a temporary import quota on the real exchange rate and the current account response is determined by the interaction between two opposing forces the intertemporal relative price effect tends to improve the current account while the wealth the intertemporal relative price effect tends to improve the current account while the wealth effect contributes to a deterioration for a sufficiently low degree of intertemporal consumption substitution the wealth effect is shown to dominate in this event the current account deteriorates in response to a temporary quota and improves only after the quota is lifted

trade and capital account liberalization in a keynesian economy this paper analyzes the process of trade and capital account liberalization in a keynesian framework with unemployed resources previous studies on this subject have ignored the potential interactions between the liberalization process and the pre existing distortions in the economy this paper derives the optimal liberalization policy given the keynesian context and solves for explicit formulas for the import tariffs and the capital account tax in a two period general equilibrium model it is argued that a trade reform is likely to have recessionary effects in the short run if the capital account has already been liberalized

fertility and the real exchange rate we use a quinquennial data set covering 87 countries between 1975 and 2005 to investigate empirically the relationship between fertility and the real effective exchange rate theoretically a country experiencing a decline in its fertility rate can be expected to experience a real depreciation we test and confirm this hypothesis controlling for a number of other potential determinants we find a statistically significant and robust link between fertility and the exchange rate our point estimate is that a decline in the fertility rate of one child per woman is associated with a depreciation of approximately 15 in the real effective exchange rate on utilise une base de donnees quinquennales pour 87 pays entre 1975 et 2005 afin d etudier empiriquement la relation entre fecondite et taux de change reel effectif theoriquement un pays qui fait l experience d un declin dans le taux de fecondite peut s attendre a une depreciation reelle on teste et on confirme que c est le cas en controlant un certain nombre d autres determinants potentiels il existe une relation significative et robuste entre fecondite et taux de change un declin du taux de fecondite d un enfant par femme est associea une depreciation d a peu pres 15 dans le taux de change reel effectif
