international transfers the relative price of non traded goods and the current account this paper considers the role of the relative price of non traded goods and the current account in the adjustment of a small open economy to the receipt of an international transfer the paper shows that the economy s macroeconomic adjustment to the transfer depends upon the relative capital intensities of the traded and non traded sectors of the economy as well as on the duration of the transfer the paper provides a new interpretation of france s current account surplus in the 1870s that accompanied the payment of reparations to germany following the franco prussian war and of germany s trade deficit in the 1920s that accompanied reparations payments associated with the first world war

the penn balassa samuelson effect through the lens of the dependent economy model abstract the positive correlation between per capita income and cross country price levels is called the penn balassa samuelson effect the most influential explanation of this effect centers around sectoral output productivities as the determinant of the relative price of nontraded goods the interaction between the change in relative prices and the change in per capita income the dynamic pbs effect is less well known this paper extends the turnovsky and sen 1995 model of a small open economy by adding external economies into the production function the model s dynamics accord well with several features of the empirical data on the dynamic pbs effect

natural resources and economic development new panel evidence the question as to whether natural resources are a curse on economic growth and development is subject to considerable debates and remains controversial using heterogeneous panel cointegration techniques this paper provides a fresh re examination of the resource curse while allowing for cross section heterogeneity and commonalities in the nexus between natural resource abundance and economic development it finds in a sample of developing countries that economies endowed with abundant natural resources tend to develop more slowly than countries with scarce resources natural resources are on average a curse however there is considerable heterogeneity in the effects of resource abundance on economic development across countries perhaps because of differences in the extent of government intervention access to sound money legal structures and the security of property rights the degree of globalization and or corruption

who pays for the minimum wage this paper analyzes the eects of a large 60 and persistent increase in the minimum wage instituted in hungary in 2001 we propose a new approach to estimating the employment eects of a minimum wage increase that exploits information on the distribution of wages before and after the policy change we infer the number of jobs destroyed by comparing the number of pre reform jobs below the new minimum wage to the excess number of jobs paying at and above the new minimum wage our estimates imply that the higher minimum wage had at most a small negative eect on employment and so the main eect was pushing up wages we then use data on a large panel of firms to evaluate the economic incidence of the minimum wage increase contrary to theoretical models that attribute the small employment eects of minimum wage changes to monopsonistic wage setting we find no evidence that the rise in the minimum wage led to lower profitability among low wage employers instead we find that the costs of the minimum wage were largely passed through to consumers

increasing returns to scale in financial intermediation and the non neutrality of government policy a general equilibrium model of imperfectly competitive financial intermediaries is constructed and used to study the effects of some standard policy experiments one time increases in the growth rate and in the level of the stock of money have non neutral and sometimes surprising effects on interest rates the quantity of intermediated borrowing and lending the number of intermediary firms inflation and the price level optimal government macroeconomic policy is shown to reflect a tradeoff between public sector frictions and the capital market distortion created by increasing returns to scale and imperfect competition in private intermediation

natural resource booms and inequality theory and evidence we develop a theory in the context of a two sector growth model in which learning by doing drives growth to explain the time path of income inequality following natural resource booms in resource rich countries under the condition of a relatively unskilled labor intensive non traded sector inequality falls immediately after a boom and then increases steadily over time until the initial impact of the boom disappears using data for 90 countries between 1965 and 1999 we find evidence in support of the theory especially for oil and mineral booms we also find that uncertainty about future commodity prices increases long run inequality

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

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

where the minimum wage bites hard introduction of minimum wages to a low wage sector between 1993 and april 1999 there was no minimum wage in the united kingdom except in agriculture in this paper we study the effects of the introduction of a national minimum wage nmw in april 1999 on one heavily affected sector the residential care homes industry this sector contains a large number of low paid workers and as such can be viewed as being very vulnerable to minimum wage legislation we look at the impact on both wages and employment our results suggest that the minimum wage raised the wages of a large number of care home workers causing a very big wage compression of the lower end of the wage distribution thereby strongly reducing wage inequality there is some evidence of employment and hours reductions after the minimum wage introduction though the estimated effects are not that sizable given how heavily the wage structure was affected

sectoral adjustment costs and real exchange rate dynamics in a two sector dependent economy abstract this paper develops a two sector model in which intersectoral capital movements involve adjustment costs expressed as capital lost in the transformation process these costs have important consequences for the dynamics of capital accumulation and particularly for real exchange rate dynamics persistent deviations of the real exchange rate from its equilibrium are derived and for plausible values of the adjustment cost parameters are consistent with the observed degree of real exchange rate persistence for low adjustment costs the dynamics are qualitatively similar to those of the standard heckscher ohlin technology for high adjustment costs the model converges to the specific factors model thus our framework includes these two standard models as polar extremes

unemployment in britain male unemployment in britain has risen from around 2 per cent in the 1950s to around 17 per cent in 1985 see figure 1 the figures are for male unemployment because there is no consistent series for women 1 even more remarkably unemployment has fallen in only three years out of the last twenty 1973 1978 and 1979 to account for this we need a model that explains both changes in the natural or non accelerating inflation rate of unemployment nairu and deviations from it we use a three equation supply side model centred on the labour market this has two main features the first concerns the determination of employment in the short run the labour demand function that we use cuts through the fruitless debate now raging especially in europe as to whether current unemployment is classical or keynesian according to the classical view employment is too high because real wages are too high according to the keynesian view real wages are not binding and unemployment is high because the product market does not clear with prices too high relative to nominal demand the whole debate is set in the framework of perfect competition yet in perfect competition prices are set by impersonal forces and it is not clear what could possibly stop prices clearing the market it is much more reasonable to think of prices as being set by imperfectly competitive firms existing prices being the best they can think of given the demand they face in this context firms demand for labour will depend on both the real product wage and the level of real aggregate demand this is the demand function we estimate and it conforms both to common sense and to the data however this does not imply that employment can be made to grow without limit by pumping up real demand for in the medium term when price surprises are eliminated our model determines three variables employment real wages and real demand on the basis of three equations an employment equation a price equation and a wage equation thus in the medium term there is a natural level of employment and corresponding to this a natural level of real aggregate demand the second key feature of our model concerns the medium term determination of unemployment in the medium term the planned mark up of wages over prices in wage settlements must be consistent with the mark up of prices over wage costs in employers pricing behaviour for if wage setters try to set real product wages higher than is consistent with employers pricing behaviour this generates ever increasing inflation thus the key to understanding unemployment in the medium term is the behaviour of wage setters if events occur that push them towards too high real wages then unemployment has to rise to offset these influences we shall call these influences wage pressure variables or push factors and they are clearly crucial in understanding unemployment the variables here include the social security system employment protection

the effect of doubling the minimum wage and decreasing taxes on inflation in mexico abstract we analyze the effect on inflation of doubling the minimum wage and cutting the value added tax in half annual inflation decreased by 1 8 percentage points suggesting that the minimum wage increase had a limited or even null effect on prices

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

prospects for commodity exporters those low income countries that export non agricultural commodities are in the midst of a resource transfer it is undoubtedly the biggest opportunity for transformative development that these societies have experienced dwarfing both aid and previous commodity booms to get it in proportion in 2004 commodity exports from sub saharan africa accounted for 146 billion us dollars or 28 percent of the region s gdp while aid amounted to 5 percent of gdp compared with the boom of the 1970s many more countries are beneficiaries the push to diversify sources of supply has resulted in exploitable discoveries in places that were previously political no go areas further whereas the boom of the 1970s was conjured up by the opec cartel this one is grounded in asian growth and so is intrinsically less precarious in this paper the authors draw on a range of new research that provides a prognosis of prospects a diagnostic of likely problems and prescribes an agenda for international action the paper is organized around these three objectives

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

trade linkages and macroeconomic effects of the price of oil in this paper we assess the impact of oil price shocks on oil producer and oil consuming economies var models for different countries are linked together via a trade matrix as in abeysinghe 2001 as expected we find that oil producers here russia and canada benefit from oil price shocks for example a large oil shock leading to a price increase of 50 boosts russian gdp by about 6 however oil producers are hurt by indirect effects of positive oil price shocks as economic activity in their exporter countries suffers for oil consumers the effects are more diverse in some countries output falls in response to an oil price shock while other countries seem to be relatively immune to oil price changes finally indirect effects are also detected for oil consumer countries those countries which trade more with oil producers gain indirect benefits via higher demand from oil producing countries in general the largest negative total effects from positive oil price shocks are found for japan china the usa finland and switzerland while other countries in our sample seem to have fared quite well during recent positive oil price shocks the indirect effects are negative for russia finland germany and netherlands

a survey of the effects of the minimum wage on prices abstract it is well established in the literature that minimum wage increases compress the wage distribution firms respond to these higher labour costs by reducing employment reducing profits or raising prices while there are hundreds of studies on the employment effect of the minimum wage there are merely a handful of studies on its profit effects and only a couple of dozen studies on its price effects furthermore a comprehensive survey on minimum wage price effects is not available in the literature given the policy relevance of this neglected issue in this paper we summarize and critically compare the available evidence on the effects of minimum wages on prices

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

do minimum wage price effects hurt the poor more minimum wage legislation is potentially a powerful policy tool to help alleviate poverty in developing countries this is especially the case when the detrimental employment effects are small however of critical importance is whether and to what extent minimum wage increases will generate price effects that might adversely affect the poor this might occur firstly if the poor consume a lot of goods produced in sectors dominated by minimum wage workforces secondly this may occur if minimum wage increases raise overall prices as the poor disproportionately suffer from inflationary costs in this paper we estimate minimum wage price effects for brazil using monthly household and firm data over nearly two decades we find that minimum wage increases significantly raise overall prices in brazil furthermore we examine the price effect of the minimum wage separately on poor and rich consumers the poor experience inflation rates three times higher that the latter in the immediate aftermath of a minimum wage increase with the differential effect diminishing over time

finance and the sources of growth the authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources total factor productivity growth physical capital accumulation and private saving they use 1 a pure cross country instrumental variable estimator to extract the exogenous component of banking development and 2 a new panel technique that controls for country specific effects and endogeneity they find that banks do exert a large causal impact on total factor productivity growth which feeds through to overall gdp gross domestic product growth the long run links between banking development and both capital growth and private savings are more tenuous
