time to build and aggregate fluctuations some new evidence this paper presents maximum likelihood estimates and tests of a model similar to one kydland and prescott 1982 suggested for this purpose it derives equilibrium laws of motion for a set of aggregate variables as functions of the model s parameters and the innovation to the technology shock the paper shows that a single unobservable index can explain the variability in the observed series but identifying the single index with the innovation to the technology shock implies that per capita hours is not well explained it also shows that time separable preferences with respect to leisure are consistent with the data copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

oil wealth and regime survival in the developing world 1960 1999 the global oil market and its associated booms and busts have generated a large literature in political science one contention in this literature is that political instability is a near certain long term outcome of oil wealth another line of argument maintains just the opposite that oil makes authoritarian regimes stronger by funding patronage and repressive apparatuses in this article i conduct the first cross national tests of these arguments and investigate the effects of oil wealth and the oil booms and busts on political stability drawing on data from 107 developing countries between 1960 and 1999 i estimate the effects of oil wealth on regime failure antistate social protest and domestic armed conflict thus as a first goal this article addresses an analytic shortcoming in previous studies by separating regime survival empirically from both economic policy and regime type democratic or authoritarian and by focusing on the direct effects of oil wealth on several measures of political stability i address the relationship between oil wealth and these outcomes both by comparing exporters to the rest of the developing world and by comparing oil rich states across pre boom boom and bust periods the results indicate that oil wealth is robustly associated with more durable regimes and significantly related to lower levels of protest and civil war moreover

international trade and business cycles is vertical specialization the missing link within academic and policy circles it is a given that international trade is important in transmitting business cycles from one country to another most analyses of the effects of the 1997 1998 asia currency crisis on the world economy focused on the trade linkages between the asian crisis countries and the rest of the world with mounting evidence of a slowdown in u s growth questions have already been raised about the effect of a reduction in u s imports on emerging economies indeed the metaphor when the u s sneezes europe catches a cold is often invoked to highlight the importance of these linkages recent empirical research has reaffirmed the above wisdom by finding that pairs of countries with stronger international trade linkages tend to have more highly correlated business cycles the goal of this paper is to examine whether these findings can be explained by standard international business cycle models we focus on the model by david backus et al 1994 which is the workhorse two good internationalbusiness cycle model in the backus et al 1994 model trade is induced by an armington aggregator which combines domestic and foreign intermediate goods to produce the final good while the aggregator has the drawback of forcing the specialization pattern to be determined in advance flying in the face of trade theory it has been very useful in quantitative and empirical applications we add transportation costs to the model in order to be consistent with the empirical research frankel and rose 1998 clark and van wincoop 2001 which deals with the endogeneity of trade by employing instrumental variables such as distance and adjacency we simulate the model and compute the effect of different transportation costs different trade intensities on the correlation of business cycles our main result is that the standard international business cycle model cannot deliver results that are quantitatively consistent with the recent empirical work in a world of fully integrated asset markets the model delivers a qualitatively counterfactual result as high trade intensity is associated with lower businesscycle correlations under portfolio autarky the model delivers increased correlations as trade intensity increases but the increased correlation is only a fraction of what it is in the data we then introduce the idea that an increasing amount of trade is vertical or fragmented countries increasingly specialize in particular stages of a good s production sequence as opposed to producing the entire good allowing for more of this back and forth trade might lead to greater business cycle correlation responsiveness to stronger trade ties however we find that adding the simplest form of vertical specialization to the model also falls short

measuring world business cycles using kalman filtering and dynamic factor analysis the authors decompose aggregate output consumption and investment for the g7 countries into factors that are 1 common across all countries and aggregates 2 common across aggregates within a country and 3 specific to each individual aggregate in quarterly data for the period 1970 through 1993 fluctuations in all aggregates contain world and country specific common components that are both statistically significant and quantitatively important the authors find that the world and country specific common components play different roles in different business cycle episodes for each of the seven countries and that either may be dominant during a particular episode copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

global implications of self oriented national monetary rules author s obstfeld maurice rogoff kenneth abstract it is well known that if international linkages are relatively small the potential gains to international monetary policy coordination are typically quite limited but what if goods and financial markets are tightly linked is it then problematic if countries unilaterally design their institutions for monetary stabilization are the stabilization gains from having separate currencies largely squandered in the absence of effective international monetary coordination we argue that under plausible assumptions the answer is no unless risk aversion is very high lack of coordination in rule setting is a second order problem compared to the overall gains from monetary policy stabilization

global business cycles convergence or decoupling we analyze the evolution of the degree of global cyclical interdependence over the period 1960 2008 using a dynamic factor model we decompose macroeconomic fluctuations in output consumption and investment into a global factor factors specific to country groups and country specific factors we find that during 1985 2008 there is some convergence of business cycle fluctuations among industrial economies and among emerging market economies surprisingly there is a concomitant decline in the relative importance of the global factor we conclude that there is evidence of business cycle convergence within each of these two groups of countries but divergence or decoupling between them

let s get real a factor analytical approach to disaggregated business cycle dynamics this paper develops a method for analysing the dynamics of large cross sections based on a factor analytic model we use law of large numbers arguments to show that the number of common factors can be determined by a principal components method the economy wide shocks can be identified by means of simple structural var techniques and that the parameters of the unobserved factor model can be estimated consistently by applying ols equation by equation we distinguish between a technological and a non technological shock identification is obtained by minimizing the negative realizations of the technology shock empirical results on 4 digit industrial output and productivity for the u s economy from 1958 to 1986 show that 1 at least two economy wide shocks both having a long run effect on sectoral output are needed to explain the common dynamics 2 although the technological shock accounts for at least 50 of the aggregate dynamics of output it cannot by itself explain dynamics at business cycle frequencies 3 sector specific shocks explain the main bulk of total variance but generate mainly high frequency dynamics 4 both the technological and the non technological component of output show a peak for positive sectoral comovements of output at business cycle frequencies 5 technological shocks are strongly correlated with the growth rates of the investment in machinery and equipment sectors and their inputs many interesting questions about cyclical fluctuations and economic growth can be answered only by studying the dynamic behaviour of sectoral variables when data contain information on time for a large cross section of sectors traditional econometric techniques used in the macroeconomic literature such as vector autoregressive var and vector autoregressive moving average varma models are not appropriate since they require the estimation of too many parameters this is why new methods which allow for the reduction of the parameter space need to be developed the objective of this paper is both methodological and descriptive at the methodological level we develop a simple framework for the dynamic analysis of large cross sections the basic model is a dynamic factor analytic model as in sargent and sims 1977 the sectoral variables are decomposed into two unobservable components a common component driven by macroeconomic shocks and a purely sectoral component when

dissecting the cycle a methodological investigation following burns and mitchell we define the cycle as a pattern in the level of aggregate economic activity an algorithm to locate turning points is developed as is a new measure of pro cyclicality a link between turning points and the moments of the series is established thereby providing the statistical foundation that burns and mitchell s work lacked using these tools we are able to dissect cycles in terms of the contributions made by trend growth volatility serial correlation and non linear effects we dissect several models and find little evidence that certain non linear effects are important to the nature of business cycles

islam authoritarianism and female empowerment what are the linkages most islamic countries are governed by authoritarian regimes and in most islamic countries women s economic social and political rights are significantly less than those of the men of their country these well known facts provide the basis for a highly original and important analysis by m steven fish 1 fish s major contribution is his suggestion that the relationships at issue are not merely a matter of spurious correlation but rather are indicative of a deep underlying causal pattern in a sophisticated cross national quantitative analysis he shows the following 1 even controlling for many other alleged influences on countries political systems countries with a largely islamic religious tradition have significantly more autocratic governments than do non islamic countries 2 controlling for level of economic development the condition of women is significantly worse in islamic countries than in others 3 in a more limited test even when controlling for economic development and islamic tradition a low level of women s rights may produce lower levels of democracy 4 more speculatively islamic states may be more autocratic so as to repress women s rights more effectively or autocratic government may permit and even require the repression of a range of human rights including those of women

comparative democracy the economic development thesis in comparative politics an established finding that economic development fosters democratic performance has recently come under challenge we counter this challenge with a dynamic pooled time series analysis of a major but neglected data set from 131 nations the final generalized least squares autoregressive moving averages estimates n 2 096 appear robust and indicate strong economic development effects dependent in part on the nation s position in the world system for the first time rather hard evidence is offered on the causal relationship between economics and democracy according to granger tests economic development causes democracy but democracy does not cause economic development overall the various tests would seem to advance sharply the modeling of democratic performance

history lessons institutions factor endowments and paths of development in the new world the explanations offered for the contrasting records of long run growth and development among the societies of north and south america most often focus on institutions the traditional explanations for the sources of these differences in institutions typically highlight the significance of national heritage or religion we in contrast argue that a hemispheric perspective across the wide range of colonies established in the new world by the europeans suggests that although there were many influences factor endowments or initial conditions had profound and enduring effects on the long run paths of institutional and economic development followed by the respective economies

development growth and policy reform in the middle east and north africa since 1950 prior to 1950 the countries of the middle east exhibited some of the lowest levels of socioeconomic development in the world for many of these countries not even approximate economic statistics are available for the first half of the twentieth century but the state of underdevelopment can be illustrated by looking at egypt the most modernized and populous country in the arab world at the time egyptian per capita income stagnated in the first half of the twentieth century the country lacked modern industries and relied largely on the cotton sector for export and government revenues but agricultural productivity had been on a steady decline since the end of the nineteenth century owen and pamuk 1998 prior to land reforms in 1952 three quarters of peasants in this agrarian country owned less than an acre or no land at all the neglect of human services allowed periodic epidemics and malnutrition to keep mortality rates high until the late 1940s education levels were well below other developing regions with adult illiteracy estimated at 85 percent in 1939 and only 23 percent of children ages 5 19 enrolled in school but in the 1960s and 1970s egypt and other countries of the middle east experienced robust economic growth based largely on high levels of investment in physical capital that facilitated substantial increases in per capita income it might seem obvious that the higher oil prices of the 1970s should have sustained the growth cycle in this oil exporting region but gdp growth per worker in the middle east decelerated in that decade and factor productivity growth actually turned negative in the 1980s and 1990s gdp growth per worker in the region was less than 1 percent per year and modest gains in human capital were largely offset by

determinants of democracy a panel study of over 100 countries from 1960 to 1995 finds that improvements in the standard of living predict increase in democracy as measured by a subjective indicator of electoral rights the propensity for democracy rises with per capita gdp primary schooling and a smaller gap between male and female primary attainment for a given standard of living democaracy tends to fall with urbnization and with a greater reliance on natrual resources democracy has little relation to country size but rises with the middle class share of income the apparently strong relation of democracy to colonial heritage mostly disappears when the economic variables are held constant similarly the allowance for these economic variables weakens the interplay between democracy and religious affiliation however negative effects from muslim and non religious affiliations remain intact

democracy stability and dichotomies an early debate in the empirical study of political democracy concerned the measurement of democracy initial work employed dichotomous indicators and incorporated stability into political democracy measures evidence accumulated showing that this approach could adversely affect analyses particularly in the study of income inequality despite this some recent studies have renewed the flawed practices we draw upon recent work to highlight the confusion that can result when democracy and stability are confounded and the problems with dichotomous indicators we propose that stability is analytically distinct from political democracy and should be treated as such empirically and we suggest ways to estimate incremental effects of political democracy we further argue that political democracy is continuous and that measures of it should reflect this it is important that the measurement history of this construct not repeat itself

the need for international policy coordination what s old what s new what s yet to come the first generation of policy coordination models was introduced some 25 years ago it provided a rationale for policy coordination but the gains from coordination were generally thought to be small now a new generation of policy coordination models is emerging incorporating monopolistic competition and nominal inertia here we examine macroeconomic interdependence and the scope for policy coordination in a tractable second generation model with two countries and multiple sectors initial calibration of the model suggests that second generation models may have more scope for policy coordination than did the first d 2004 elsevier b v all rights reserved

liberalizing autocracies in the gulf region reform strategies in the face of a cultural economic syndrome from an international comparative perspective the stability of autocratic regimes in the countries of the gulf region is striking this paper presents historical cultural as well as economic explanations and proposes that the interaction of both factors constitutes a cultural economic syndrome accounting for the persistence of authoritarianism macro quantitative analyses demonstrate the significant influence of this syndrome which operates through a mechanism of mutual reinforcement and substitution departing from this diagnosis potential remedies are discussed political and economic reform measures pursued in the 1990s are explored and the gulf monarchies are classified according to four ideal typical combinations of reform strategies

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

macroeconomic forecasting using diffusion indexes this article studies forecasting a macroeconomic time series variable using a large number of predictors the predictors are summarized using a small number of indexes constructed by principal component analysis an approximate dynamic factor model serves as the statistical framework for the estimation of the indexes and construction of the forecasts the method is used to construct 6 12 and 24 monthahead forecasts for eight monthly u s macroeconomic time series using 215 predictors in simulated real time from 1970 through 1998 during this sample period these new forecasts outperformed univariate autoregressions small vector autoregressions and leading indicator models

does financial globalization promote risk sharing article i nfo in theory one of the main benefits of financial globalization is that it should allow for more efficient international risk sharing in this paper we provide an empirical evaluation of the patterns of risk sharing among different groups of countries and examine how international financial integration has affected the evolution of these patterns using a variety of empirical techniques we conclude that there is at best a modest degree of international risk sharing and certainly nowhere near the levels predicted by theory in addition only industrial countries have attained better risk sharing outcomes during the recent period of globalization developing countries have by and large been shut out of this benefit even emerging market economies many of which have reduced capital controls and all of which have witnessed large increases in cross border capital flows have seen little change in their ability to share risk we find that the composition of flows may help explain why emerging markets have not been able to realize this presumed benefi to f financial globalization in particular our results suggest that portfolio debt which had dominated the external liability stocks of most emerging markets until recently is not conducive to risk sharing
