the relationship between the markup and inflation in the g7 economies and australia an i 2 analysis of inflation and the markup is undertaken for the g7 economies and australia we find that the levels of prices and costs are best described as i 2 processes and that except for japan a linear combination of the log levels of prices and costs cointegrate to the markup that is integrated of order 1 it is also shown that the markup in each case co integrates with inflation and that higher inflation is associated with a lower markup in the long run

growth distribution and environment macroeconomic issues in zimbabwe abstract the main policy challenges in zimbabwe relate to generating income growth reducing poverty and stopping land degradation the government attempted redistribution with growth at independence but ran into macroeconomic unsustainability after a period of import compression the government now has embarked upon a liberalization program the consequences for growth and distribution so far have been unfavorable and the economic structure has been reoriented toward primary goods it is hard to see this strategy as helpful in terms of poverty and land degradation the article throws some light on the macroeconomic aspects of the development strategy using an economywide computable general equilibrium cge model and evaluates the conditions for land reform to improve on distribution and environment

workers response to job loss female and male industrial workers in brazil abstract it is often assumed that when formal sector workers in the third world lose their jobs during a recession they move into the informal sector lack of state support rules out long periods of unemployment above all for breadwinners a survey of industrial workers in brazil shows that following job loss in the early 1980s resorting to the informal sector was more common for women than men and less likely for the skilled than the unskilled unemployment and a return to industrial employment were most common experiences for male breadwinners workers preferences and the structure of labor market opportunities explain much of this behavior

dynamic relationship between financial development energy consumption trade and greenhouse gas comparison of upper middle income countries from asia europe africa and america the paper explores the nexus between greenhouse gas financial development energy consumption trade and urbanization in 34 upper middle income countries from asia europe africa and america south and north by using panel data from 2001 to 2014 vector error correction model explored different results for different regions such as the causality of greenhouse gas for europe and america financial development for asia trade openness for asia europe and america and urbanization for africa and america the causality of greenhouse gas emission was bi directional with urbanization in america and trade in europe the bi directional causality of trade was observed with financial development in asia and urbanization in africa the generalized method of moment and fully modified ordinary least square explored a direct association of per capita greenhouse gas emission with financial development in europe energy consumption in all panels and renewable energy in africa and america but the relationship of per capita emission was reciprocal with financial development in asia africa and america renewable energy in europe trade in europe africa and america and urbanization in asia europe and america the relationship of variables changes from region to region and country to country a country based reciprocal effect on per capita greenhouse gas was observed for financial development renewable energy trade openness and urbanization for different countries this paper provides an insight to policy makers to re structure the financial system energy usage pattern trade and urbanization in accordance with the cleaning of environment at country and regional level

stock market returns and inflation evidence from other countries this paper investigates the relation between common stock returns and inflation in twenty six countries for the postwar period our results do not support the fisher hypothesis which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one to one correspondence with expected inflation there is a consistent lack of positive relation between stock returns and inflation in most of the countries

household energy consumption versus income and relative standard of living a panel approach our fundamental premise is that energy consumption at the household level is a key indicator of standard of living we employ state of the art panel cointegration techniques to evaluate the nature of the relationship between income measures and energy consumption measures for seven east indian ocean countries the general finding is that income and household electricity consumption are not cointegrated given this finding we conclude that standard of living measures that rely on income measures and do not include household level energy consumption information will necessarily miss important indications of both levels and changes of standard of living

price competition in an inflationary environment we study how inflation and deflation affect firms ability to cooperate in an experimental bertrand duopoly with differentiated products we find that there is significantly less cooperation in the treatments with inflation and deflation compared to the no inflation treatments the difficulties to cooperate affect prices and welfare depending on the market structure inflation and deflation lead to significantly lower real prices and higher welfare

interest rates and the fisher effect in india an empirical study abstract this study throws light on the importance of adjustment lags variability of inflation changes in real income etc in the empirical estimation of fisher hypothesis variability of inflation has a significant negative impact on both short and long term interest rates in a developing economy like india the philips curve effect has not been operative in a developing country

collusion and price rigidity we consider an in nitely repeated bertrand game in which prices are publicly observed and each rm receives a privately observed i i d cost shock in each period we focus on symmetric perfect public equilibria sppe wherein any punishments are borne equally by all rms we identify a tradeoff that is associated with collusive pricing schemes in which the price to be charged by each rm is strictly increasing in its cost level such fully sorting schemes offer efficiency bene ts as they ensure that the lowest cost rm makes the current sale but they also imply an informational cost distorted pricing and or equilibrium path price wars since a higher cost rm must be deterred from mimicking a lower cost rm by charging a lower price a rigid pricing scheme where a rm s collusive price is independent of its current cost position sacri ces efficiency bene ts but also diminishes the informational cost for a wide range of settings the optimal symmetric collusive scheme requires i the absence of equilibrium path price wars and ii a rigid price if rms are sufficiently impatient however the rigid pricing scheme cannot be enforced and the collusive price of lower cost rms may be distorted downward in order to diminish the incentive to cheat when the model is modi ed to include i i d public demand shocks the downward pricing distortion that accompanies a rm s lower cost realization may occur only when current demand is high

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

macroeconomic adjustment and the poor analytical issues and cross country evidence the author studies the links between macroeconomic adjustment and poverty first he summarizes some of the recent evidence on poverty in the developing world second he reviews the various channels through which macroeconomic policies affect the poor third the author emphasizes the role of the labor market he develops an analytical framework that captures some of the main features of the urban labor market in developing countries and studies the effects of fiscal adjustment on wages employment and poverty fourth he presents cross country regressions linking various macroeconomic and structural variables to poverty the author finds that output growth and real exchange rate depreciations tend to lower poverty while illiteracy income inequality and macroeconomic volatility tend to increase poverty in addition the impact of growth on poverty appears to be asymmetric and to result from a significant relationship between episodes of increasing poverty and negative growth rates

an analysis of gasoline demand elasticities at the national and local levels in mexico abstract the majority of evidence on gasoline demand elasticities is derived from models based on national data since the largest growth in population is now taking place in cities in the developing world it is important that we understand whether this national evidence is applicable to demand conditions at the local level the aim of this paper is to estimate and compare gasoline per vehicle demand elasticities at the national and local levels in mexico national elasticities with respect to price income vehicle stock and metro fares are estimated using both a time series cointegration model and a panel gmm model for mexican states estimates for mexico city are derived by modifying national estimates according to mode shares as suggested by graham and glaister 2006 and by estimating a panel within groups model with data aggregated by borough although all models agree on the sign of the elasticities the magnitudes differ greatly elasticities change over time and differ between the national and local levels with smaller price responses in mexico city in general price elasticities are smaller than those reported in the gasoline demand surveys a pattern previously found in developing countries the fact that income and vehicle stock elasticities increase over time may suggest that vehicles are being used more intensively in recent years and that mexico city residents are purchasing larger vehicles elasticities with respect to metro fares are negligible which suggests little substitution between modes finally the fact that fuel efficiency elasticities are smaller than vehicle stock elasticities suggests that vehicle stock size rather than its composition has a larger impact on gasoline consumption in mexico city

testing the purchasing power parity through i 2 cointegration techniques this paper contributes to the empirical literature on the purchasing power parity ppp over the post bretton woods period by providing a time series based interpretation of the controversial evidence characterizing the dynamics of real exchange rates it is shown that the persistence of deviations from the ppp between a set of european countries and the united states may be empirically attributed to the presence of i 2 stochastic trends in prices using consumer price indices interestingly the slow adjustment towards the equilibrium can be modelled through integral proportional equilibrium correction models and this evidence can be partly reconciled with theories where the inflation rate reduces the markup of profit maximizing firms acting on imperfectly competitive markets copyright 2005 john wiley sons ltd

multicointegration in us consumption data the present study tests for the existence of multicointegration between real per capita private consumption expenditure and real per capita disposable personal income in the usa in doing so the study exploits the fact that the flows of disposable income and consumption expenditure on the one hand and the stock of consumers wealth which can be considered as cumulative past discrepancies between the flows of income and expenditure on the other hand can be thought of as a stock flow model in which multicointegration is likely to occur recently developed i 2 techniques are applied for testing for multicointegrating relations and find supporting evidence for the existence of multicointegration in us consumption data

exogenous shocks and growth crises in low income countries a vulnerability index summary this paper develops a new index which provides early warning signals of a growth crisis in the event of large external shocks in low income countries lics multivariate regression analysis and a univariate signaling approach are used to map information from a parsimonious set of underlying policy structural and institutional indicators into a composite vulnerability index both the in sample and out of sample predictive power of the index are high in particular it explains well the growth crises observed in lics during the global financial crisis

inflation and unemployment the world economy today is vastly different from the 1930s when seymour harris the chairman of this meeting infected me with his boundless enthusiasm for economics and his steadfast confidence in its capacity for good works economics is very different too both the science and its subject have changed and for the better since world war ii but there are some notable constants unemployment and inflation still preoccupy and perplex economists statesmen journalists housewives and everyone else the connection between them is the principal domestic economic burden of presidents and prime ministers and the major area of controversy and ignorance in macroeconomics i have chosen to review economic thought on this topic on this occasion partly because of its inevitable timeliness partly because of a personal interest reaching back to my first published work in 1941

labor market dynamics when unemployment is a worker discipline device efficiency wage models of the effort elicitation type have important implications for labor market dynamics these models have a wide array of discontinuous sunspot equilibria driven by extraneous variables in addition to well behaved equilibria characterized by continuous slowly adjusting patterns of employment many aspects of actual labor markets can be replicated by these models for example the longer run movements they predict in employment allow macroeconomic evidence for a large labor supply elasticity to be reconciled with panel data evidence for a small labor supply elasticity many testable but as yet untested predictions about labor market dynamics can also be generated this abstract was borrowed from another version of this item

hourly wages and working time in the dutch market sector 1962 1995 this article analyses the joint behaviour of hourly wages and standard hours in the netherlands with respect to the development of full time hours to different hypotheses are suggested work sharing or productivity sharing under the work sharing hypothesis high unemployment would lead to reduced hours whereas under productivity sharing increased productivity leads to higher wages or reduced hours the evidence is in favour of the productivity hypothesis there is no direct impact of unemployment on the evolution of hours moreover although reduced hours tend to increase hourly wages in the short run this is not the case in the long run

output gains from economic stabilization by driving a wedge between the marginal returns to real and financial capital inflation distorts production the elimination of this distortion increases both the level and rate of growth of output first increased price stability improves the utilization of capital and this increases the full employment level of output in the long run even though output decreases initially second the static output gain from stabilization is captured in a simple formula in which the gain is approximately proportional to the square of the original inflation distortion third successful stabilization increases the rate of growth of output per head and not only its level in the presence of constant returns to capital in a broad sense fourth substitution of plausible parameter estimates into the simple formulae reflecting the gains from stabilization indicate that the static and dynamic output gains can be substantial

governance quality remittances and their implications for food and nutrition security in sub saharan africa abstract despite impressive progress in the fight against malnutrition and hunger in recent years food and nutrition insecurity remains a major concern in sub saharan africa ssa countries in this study we employ a panel data covering 15 ssa countries from 1996 to 2015 to investigate the growth effects of remittances and quality of governance on food and nutrition security proxied by the average value of food production and the average dietary energy supply adequacy respectively we use a dynamic empirical model based on system gmm to control for unobserved heterogeneity and potential endogeneity of the explanatory variables the empirical results emanating from our analysis show that the interaction of remittances and the composite index of governance quality exerts positive and significant effects on the average value of food production and also contributes to the improvement of average dietary energy supply adequacy in ssa in addition the control of corruption government effectiveness political stability and rule of law scores increase both measures of food and nutrition security albeit the contribution of control over corruption score is relatively the largest as compared to other indicators of governance

german and american wage and price dynamics differences and common themes abstract the theoretical section of this paper develops a new nonstructural model of wage and price adjustment that integrates several concepts that have often been treated separately including phillips curve level effects hysteresis change effects the error correction mechanism and the role of changes in labor s share that act as a supply shock the empirical analysis reaches two striking conclusions first during 1973 1990 coefficients in our german wage equations are remarkably similar to those in the u s with almost identical estimates of the phillips curve slope of the hysteresis effect and of the nairu the two countries also share similar inflation behavior in that inflation depends more closely on the capacity utilization rate than on the unemployment rate the big difference between the two countries is that there seems to be no feedback from wages to prices in germany and so high unemployment does not put downward pressure on the inflation rate during the 1970s and 1980s in germany there emerged a growing mismatch between the labor market and industrial capacity so that the unemployment rate consistent with the mean constant inflation utilization rate muru increased sharply while in the u s the muru was relatively stable

fiscal adjustment and labor market dynamics in an open economy this paper studies the labor market effects of fiscal adjustment in a two sector three good intertemporal framework key features of the model are an informal sector minimum wages unionized labor in the formal economy imperfect labor mobility and public production of intermediate inputs bluxuryq and wait unemployment prevail in equilibrium it is shown that if unions care sufficiently about employment and if the degree of openness is high an increase in the price of government services may reduce unemployment in the steady state a similar result would hold in an efficiency wage setting if the bdisciplinary effectq of unemployment is sufficiently strong d 2004 published by elsevier b v

on the job search in a developing country an analysis based on indian data on migrants job search by those who are employed has received increasing attention in recent years in both the theoretical and the empirical literature on labor markets in developed countries much of the interest stems from the observation that job changes often take place without an intervening period of unemployment and that there is a close relationship between searching for a job and quitting the current job also on the job search affects the rate of unemployment during the period between jobs a major preoccupation of the empirical research has been to estimate the returns to on the job search and to test the determinants of job search the bulk of this work uses data for the united states and the united kingdom 2 job search theory has not been empirically tested in the context of a developing country on the job search particularly in the so called informal sector of the urban labor market is an important feature of probabilistic models of migration in developing countries in the vein of michael p todaro and of john r harris and todaro 3 such models hypothesize that individuals migrate to urban centers with the aim of obtaining employment in the formal sector and that informal sector employment is a transitional phase during which migrants are searching for formal sector jobs recent work by gary s fields has formalized the theoretical aspects of this job search process within the framework of a multisector model 4 thus it would be of interest to find out if there are significant differences between developed and developing countries with respect to the determinants of on the job search

macroeconomic performance and poverty in brazil abstract drawing on brazilian time series data this study finds an inelastic link between poverty and wages over the macroeconomic cycle that is devoid of the asymmetric effects that characterise the phenomenon s response to changes in the rate of unemployment deepening of structural reforms in the second half of the 1990s had no effect on the aforementioned relationships which also varied little by regional level of development finally the connection between poverty and long term income changes was more elastic suggesting an association between the economy s recent disappointing performance in alleviating poverty and its lacklustre growth record over the past two decades

does the law of one price hold in a high inflation environment a tale of two cities in turkey this study addresses the price convergence in two cities in turkey istanbul and ankara using annual data over the three quarters of the twentieth century 1922 1998 characterized by prevailing high inflation rates for most of the period in contrast to the rest of the literature addressing convergence in price levels with a typical result of extremely slow convergence rates at best we argue that convergence is much easier detected in growth rates rather than levels of prices we suggest using the bounds testing procedure of pesaran et al 2001 for this purpose we find a clear cut evidence on the existence of a common driving force behind inflation dynamics in istanbul and ankara a finding that is in contrast with the results typically reported in related literature

modeling inflation in australia this article develops an empirically constant data coherent error correction model for inflation in australia the level of consumer prices is a markup over domestic and import costs with adjustments for dynamics and relative aggregate demand we address issues of cointegration general to specific modeling dynamic specification model evaluation and testing parameter constancy forecasting and exogeneity we also test this model against existing models of australian prices this model encompasses but is not encompassed by the existing models

an i 2 analysis of inflation and the markup an i 2 analysis of australian inflation and the markup is undertaken within an imperfect competition model it is found that the levels of prices and costs are best characterized as integrated of order 2 and that a linear combination of the levels which may be defined as the markup cointegrates with price inflation from the empirical analysis we obtain a long run relationship where higher inflation is associated with a lower markup and vice versa the impact in the long run of inflation on the markup is interpreted as the cost to firms of overcoming missing information when adjusting prices in an inflationary environment copyright 2001 john wiley sons ltd

panel estimation for co2 emissions energy consumption economic growth trade openness and urbanization of newly industrialized countries abstract this paper empirically examines the dynamic causal relationships between carbon dioxide emissions energy consumption economic growth trade openness and urbanization for the panel of newly industrialized countries nic using the time series data for the period 1971 2007 using four different panel unit root tests it is found that all panel variables are integrated of order 1 from the johansen fisher panel cointegration test it is found that there is a cointegration vector among the variables the granger causality test results support that there is no evidence of long run causal relationship but there is unidirectional short run causal relationship from economic growth and trade openness to carbon dioxide emissions from economic growth to energy consumption from trade openness to economic growth from urbanization to economic growth and from trade openness to urbanization it is found that the long run elasticity of carbon dioxide emissions with respect to energy consumption 1 2189 is higher than short run elasticity of 0 5984 this indicates that over time higher energy consumption in the newly industrialized countries gives rise to more carbon dioxide emissions as a result our environment will be polluted more but in respect of economic growth trade openness and urbanization the environmental quality is found to be normal good in the long run

modelling uk inflation 1875 1991 uk inflation has varied greatly in response to many economic policy and exchange rate regime shifts two world wars and two oil crises as well as legislative and technological changes inflation is modelled as responding to excess demands from all sectors of the economy goods and services factors of production money financial assets foreign exchange and government deficits equilibrium correction terms are developed for each of these over the sample indicator variables and commodity prices capture turbulent years variables representative of most theories of inflation matter empirically yielding an eclectic model inconsistent with any single cause explanation copyright 2001 john wiley sons ltd

the cyclical behavior of marginal cost and price the author examines the cyclical behavior of price marginal cost margins for u s manufac turing after 1956 short run marginal cost is markedly procyclical this is primarily due to procyclical overtime payments incurred beca use employment is not perfectly flexible in most industries output price fails to respond to the cyclical movement in marginal cost so price marginal cost margins are markedly countercyclical the res ults contradict business cycle theories that explain low production i n a recession by a high real cost of producing they support theories that explain low production in a recession by the inability of firms to sell their output copyright 1987 by american economic association

central bank policies and income and wealth inequality a survey this paper reviews recent research on the relationship between central bank policies and inequality a new paradigm which integrates sticky prices incomplete markets and heterogeneity among households is emerging which allows for the joint study of how inequality shapes macroeconomic aggregates and how macroeconomic shocks and policies affect inequality the new paradigm features multiple distributional channels of monetary policy most empirical studies however analyze each potential channel of redistribution in isolation our review suggests that empirical research on the effects of conventional monetary policy on income and wealth inequality yields mixed findings although there seems to be a consensus that higher inflation at least above some threshold increases inequality in contrast to common wisdom conclusions concerning the impact of unconventional monetary policies on inequality are also not clear cut to better understand policy effects on inequality future research should focus on the estimation of general equilibrium models with heterogeneous agents

macroeconomic stability investment and growth in developing countries abstract it is widely hypothesised that sound macroeconomic policies promote growth by providing a more secure environment for private sector investment decisions this proposition is tested for a cross section of developing countries over the period 1980 1990 using a variety of measures of the quality of macroeconomic management the evidence suggests that good macroeconomic management is associated with faster growth for a given rate of investment it is less clear that the volume of investment is significantly affected there is little evidence of non linearities the results are robust to an extension of the data period back to 1972

a test of dual labor market theory despite substantial differences in their views of the appropriate policy response to the existence of poverty neither the proponents of dual market theory nor its critics have proposed potentially conclusive tests of the dual market hypothesis this paper presents a test of the two central propositions of dual market theory 1 the existence of two distinct labor markets with different wage setting mechanisms and 2 the existence of barriers to mobility between the labor markets we find considerable support for both hypothesis estimation of a switching model of wage determination with unknown regimes yields two distinct wage equations the one which most workers are associated with closely resembles the standard human capital regression with significant returns to education and experience the other equation is flat with no returns to human capital these two equations resemble the predictions of dual market theory for the primary and secondary markets respectively further we present evidence that at least some non white workers are involuntarily confined to the secondary market this crowding of minority workers into the low wage labor market accounts for a substantial portion of white non white wage differences we interpret these results as providing empirical support for the dual market hypothesis and for recent theoretical work on efficiency wagemodels in addition combining the efficiency wage argument with the observation that much of the white non white wage difference is explained by the exclusion of non whites from the primary sector suggests an explanation for the persistance of wage differences this abstract was borrowed from another version of this item

medium run adjustment under import compression macroeconomic analysis relevant for sub saharan africa abstract the dynamic small open economy model of kouri 1979 is modified to analyze the role of the foreign exchange constraint in import dependent economies typical for sub saharan africa structural adjustment and investment allocation are related to the sectoral balance between traded and protected goods the import compression policy of the region establishes a linkage between the export performance of the traded sector and the capacity utilization of the protected sector it is shown that the relationship implies possible contractionary effects of demand expansion since exports are crowded out and the import capacity is reduced a destabilizing downward growth spiral may follow policies modifying the excessive demand and the import dependency seem necessary to turn contraction into growth

rural urban migration in economic development abstract this paper provides a review of the theoretical literature on rural urban migration in contemporary ldcs the paper begins with a brief discussion of the lewis model before going on to discuss the todaro and the harris todaro models and the large literature which these models have spawned the question of job search in the context of migration and the role of family members in migration decisions are considered next the paper then takes a closer look at the informal sector and also sets out alternative migration functions to the ones usually employed in the literature the paper concludes with a brief note on some of the important implications arising from our study

a simple test of the nutrition based efficiency wage model abstract in the nutrition based efficiency wage model wages in labor markets in developing countries are rigid because lowering them would reduce worker productivity and increase the cost per efficiency unit i evaluate this claim using data from rural india i find that contrary to what has been assumed in these models a wage cut should lower the cost per efficiency unit of labor

roads out of poverty assessing the links between aid public investment growth and poverty reduction the authors develop a macroeconomic framework that captures links between aid public investment growth and poverty public investment is disaggregated into education infrastructure and health and affects both aggregate supply and demand dutch disease effects are captured by accounting for changes in the relative price of domestic goods the authors assess the impact of policy shocks on poverty by linking the model to a household survey they calibrate the model for ethiopia and simulate the changes in the allocation of aid and public investment the authors also calculate the amount by which foreign aid should increase to reach the poverty targets of the millennium development goals

linear or nonlinear cointegration in the purchasing power parity relationship we test long run purchasing power parity ppp within a general model of cointegration of linear and nonlinear form nonlinear cointegration is tested with rank tests of breitung 2001 we determine first the order of integration of each variable using monthly data from the post bretton woods era for g 10 countries in many cases prices are i 2 whereas all exchange rates are i 1 however there are several countries that have a price level that linearly cointegrates with the us price level so that this combination is i 1 overall we find some though limited evidence for nonlinear and also linear cointegration for the weak version of ppp

wages and unemployment in an urban african labour market this paper argues that urban labor markets in africa exhibit a wage curve similar to those found in the united states britain canada and other developed countries drawing on data from the ivory coast the author finds that urban wages are depressed by higher levels of unemployment this result is robust to changes in model specification and level of aggregation it is consistent with the model of wage determination developed by c shapiro and j stiglitz 1984 and d blanchflower and a oswald 1995 but not with claims that urban wages are invariant to unemployment copyright 1996 by royal economic society

a structured var for denmark under changing monetary regimes using recently developed statistical tools for analyzing cointegrated 1 2 data this article models money income prices and interest rates in denmark the final model describes the dynamic adjustment to short run changes of the process to deviations from long run steady states and to several political interventions it provides new insights about the effects of the liberalization of trade and capital in a small open european economy

school attendance child labor and local labor market fluctuations in urban brazil abstract while the income poverty effect on child labor is long established as a main determinant of child labor there is a growing body of literature considering the pull of the labor market this paper demonstrates that after controlling for household characteristics employment rates for 14 16 year old boys and girls in urban brazil increase as local labor market opportunities improve children are also more likely to leave school as local labor market conditions become more favorable the relationship between children s schooling and work and local labor market conditions changes in years of crisis compared to other years the effects of macroeconomic fluctuations on children s school and work behavior are examined with particular focus on whether the income effect or substitution effect dominates as macroeconomic conditions change over time the study uses data from the pesquisa nacional amostra de domicilios a large household survey that is conducted almost annually by the ibge we use variation in the urban areas of 25 states over 12 years to identify the aggregate effects

distributional effects of adjustment policies simulations for archetype economies in africa and latin america for developing countries the 1980s was a decade of external shocks whose adverse effects were compounded by domestic macroeconomic imbalances and structural inefficiencies the performance of developing countries during this decade however was not uniform the effects of terms of trade and interest rate shocks are simulated for two model economies one representing an average latin american economy and the other representing an average african economy in addition to the effects of the shocks the effects of different adjustment policies are examined as expected identical shocks and adjustment packages yield different outcomes for growth poverty and income distribution in the two economies the differences in results can be traced to specific features of the models and to the extent that the archetypes created are representative of real economies have implications for adjustment policy prescriptions

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association

market power price adjustment and inflation we study the responses of real and nominal prices to random flutuations in costs and money growth using a monetary search economy in which there are no costs or temporal restrictions on sellers ability to change prices the economy exhibits a form of price stickiness in that the price level may react incompletely to either type of shock as a result of endogenous changes in the average mark up driven by movements in consumers search intensity the average mark up falls as inflation rises a finding consistent with emprical observations as a result of this reduction in market power prices become more responsive to shocks as inflation rises our results are consistent with empirical findings that the degree of price adjustment in response to both cost and money growth shocks is increasing in the average rate of inflation that the variance of inflation increases with its average level and that positive and negative shocks to money growth have asymmetric effects

does trade openness contribute to food security a dynamic panel analysis abstract despite significant progress in the fight against hunger during the last decades food insecurity remains a major problem in many countries especially developing ones in this study we use a large cross country data to investigate the impact of trade openness and other factors on food security measured by dietary energy consumption we employ a system gmm approach to account for unobserved heterogeneity correlated individual effects and potential endogeneity of the explanatory variables the empirical results reveal that trade openness and economic growth exert positive and significant impacts on dietary energy consumption and also contribute to improvements in dietary diversity the results are robust to the inclusion of additional variables capturing specific agro climatic constraints e g weather related and regional country characteristics and to the sample composition most geographical regions are found to have significantly higher food security levels compared to sub saharan africa additional results indicate that besides calorie consumption trade openness also improves dietary diversity and diet quality related aspects of food security
