balancing terrorism and natural disasters defensive strategy with endogenous attacker effort in this paper we apply game theory to identify equilibrium strategies for both attacker and defender in a fully endogenous model of resource allocation for countering terrorism and natural disasters the key features of our model include balancing protection from terrorism and natural disasters and describing the attacker choice by a continuous level of effort rather than a discrete choice i e attack or not interestingly in a sequential game increased defensive investment can lead an attacker to either increase his level of effort to help compensate for the reduced probability of damage from an attack or decrease his level of effort because attacking has become less profitable this can either reduce or increase the effectiveness of investments in protection from intentional attack and can therefore affect the relative desirability of investing in protection from natural disasters

growth miracles and failures in a markov switching classification model of growth abstract in this paper economic growth is interpreted as a sequence of transitions between distinct growth regimes that countries visit with different frequencies countries featuring similar growth dynamics are endogenously grouped into three different clusters the first cluster comprises successful countries that are characterized by lengthy periods of high or very high growth moderately successful countries in the second cluster experience both periods of reasonable growth and periods of stagnation whereas failing countries in the third cluster suffer from highly volatile growth rates with frequent episodes of crisis successful countries are characterized by better initial conditions policies and institutions compared to the other countries neither initial conditions nor institutions distinguish moderately successful from failing countries what makes them different is policy in the form of investments into infrastructure and human capital trade liberalization and limited policy volatility

democracy volatility and economic development growth stability is an important objective because development requires sustained increases in income because volatility is costly for the poor and because volatility deters growth we study the determinants of average growth and its volatility as a two equation system and find that higher levels of democracy and diversification lower volatility whereas volatility itself reduces growth muslim countries instrument for democracy and measures of diversification identify volatility in contrast to the lack of consensus on the democracy growth relationship the democracy stability link is robust rather than focus on growth this paper forges an alternative link between democracy and development through the volatility channel

the political dynamics of economic growth summary we argue that an understanding of the political drivers of economic growth needs an explanation of the political dynamics around the transition from one growth phase to another and that the political drivers of early stage growth accelerations are different from that of growth maintenance informal institutions are likely to play a role in growth acceleration while formal institutions of credible commitment the provisioning of public goods and the overcoming of co ordination failures will be more important in growth maintenance we present empirical evidence drawn from country case studies and cross country econometric analysis that provides support to our theoretical propositions

a statistical approach to identifying poorly performing countries abstract this paper asks whether it is possible to identify using purely statistical criteria on widely available quantitative data a set of developing countries that can be classified as poor performers we restrict attention to two performance indicators economic growth and infant mortality over two periods 1980 90 and 1990 2000 and use four different statistical criteria to identify poor performance the main finding is that very few countries consistently appear as poor performers those that perform poorly on one indicator or in one period typically do not perform poorly on in the other a similar result is obtained in the context of identifying on statistical grounds good performers the research cautions against labelling countries as poor performers without careful qualification

to bargain or not to bargain that is the question we use economic analysis in a simple game theory framework to ascertain under what circumstances a government would want to precommit itself to a no negotiation strategy from the government viewpoint we examine both the choice of deterrence expenditure i e expense meant to reduce terrorist logistical success during incidents and whether to negotiate or not this abstract was borrowed from another version of this item

the big push natural resource booms and growth a simple application of big push reasoning suggests that natural resource booms can be important catalysts for development in poorer countries in this paper we present evidence from seven latin american countries that natural resource booms are sometimes accompa nied by declining per capita gdp we present a model with natural resources increasing returns in the spirit of big push models and expectations to clarify some of the reasons this may happen q 1999 elsevier science b v all rights reserved

the political economy of linguistic cleavages article i nfo this paper uses a linguistic tree describing the genealogical relationship between all 6912 world languages to compute measures of diversity at different levels of linguistic aggregation by doing so we let the data inform us on which linguistic cleavages are most relevant for a range of political economy outcomes rather than making ad hoc choices we find that deep cleavages originating thousands of years ago lead to better predictors of civil conflict and redistribution the opposite pattern emerges when it comes to the impact of linguistic diversity on growth and public goods provision where finer distinctions between languages matter 2011 elsevier b v all rights reserved

are any growth theories robust this article investigates the strength of empirical evidence for various growth theories when there is model uncertainty with respect to the correct growth model using model averaging methods we find little evidence that so called fundamental growth theories play an important role in explaining aggregate growth in contrast we find strong evidence for macroeconomic policy effects and a role for unexplained regional heterogeneity as well as some evidence of parameter heterogeneity in the aggregate production function we conclude that the ability of cross country growth regressions to adjudicate the relative importance of alternative growth theories is limited despite the vast amount of empirical research generated by new growth theories there is remarkably little consensus on which mechanisms are most salient in explaining cross country differences this article is designed to provide some evidence on this question by examining the robustness of empirical support for different growth the ories as determinants of both aggregate growth and its underlying components total factor productivity tfp growth and physical and human capital accumulation one reason for the lack of empirical consensus on growth determinants is that the main statistical tool in empirical studies cross country growth regressions provides very different answers depending on how the regression is specified which for this context typically amounts to the choice of control variables individual papers typically employ regressions that include modest subsets of the body of regressors that have been pro posed in the literature as a whole others employ a kitchen sink approach to evaluate the relative evidentiary support of competing growth theories in such an exercise a large number of variables are included in a regression and those variables that prove to be significant are then declared to be the important determinants of growth while the others are dismissed as unimportant rodrik et al 2002 sachs 2003

political variables in cross country growth analysis the recent boom in cross country growth analysis has renewed the empirical interest in political sources of economic growth a large number of studies have tested political variables in growth regressions and a very heterogenous set of variables has been proposed to measure economically relevant differences in the political systems of countries this paper distinguishes five categories of relevant political variables democracy government stability political violence policy volatility and subjective perception of politics for each of these categories the specification testing method and results of the most relevant studies are presented and are critically discussed the paper concludes that measures of democracy are least successful and measures of policy volatility and subjective perception of politics most successful as explanatory variables in cross country growth regressions

terrorism in a bargaining framework a lthough hostage seizures are a small percentage of terrorist incidents they represent some of the most spectacular and influential events 2 the takeover of the american embassy in tehran on november 14 1979 the seizure of eleven dpec oil ministers on december 21 1975 and the capture and killing of nine israeli athletes on september 5 1972 are incidents not easily forgotten from 1968 through 1982 of the approximately 8 000 reported terrorist events 540 7 percent were transna

the logic of political violence this paper offers a unified approach for studying political violence whether it emerges as repression or civil war we formulate a model where an incumbent or opposition can use violence to maintain or acquire power to study which political and economic factors drive one sided or two sided violence repression or civil war the model predicts a hierarchy of violence states from peace via repression to civil war and suggests a natural empirical approach exploiting only within country variation in the data we show that violence is associated with shocks that can affect wages and aid as in the theory these effects are only present where political institutions are non cohesive

what makes growth sustained abstract we identify structural breaks in economic growth in 140 countries and use these to define growth spells periods of high growth preceded by an upbreak and ending either with a downbreak or with the end of the sample growth spells tend to be shorter in african and latin american countries than elsewhere we find evidence that growth duration is positively related to the degree of equality of the income distribution democratic institutions export orientation with higher propensities to export manufactures greater openness to fdi and avoidance of exchange rate overvaluation favorable for duration and macroeconomic stability

the investment problem in terrorism evidence from early terrorist groups reveals a structural equivalence between extortion and terrorism this allows us to draw conclusions from the theory of extortion that can be applied to a theory of terrorism concerning the role of repeated play in the viability of extortion it also enables us to analyse the role of commitment in destroying the extortionary organization

can leading indicators assess country vulnerability evidence from the 2008 09 global financial crisis abstract we investigate whether leading indicators can help explain the cross country incidence of the 2008 09 financial crisis rather than looking for indicators with specific relevance to the recent crisis the selection of variables is driven by an extensive review of more than eighty papers from the previous literature on early warning indicators our motivation is to address suspicions that indicators found to be useful predictors in one round of crises are typically not useful to predict the next round the review suggests that central bank reserves and past movements in the real exchange rate were the two leading indicators that had proven the most useful in explaining crisis incidence across different countries and episodes in the past for the 2008 09 crisis we use six different variables to measure crisis incidence drops in gdp and industrial production currency depreciation stock market performance reserve losses and participation in an imf program we find that the level of reserves in 2007 appears as a consistent and statistically significant leading indicator of who got hit by the 2008 09 crisis in line with the conclusions of the pre 2008 literature in addition to reserves recent real appreciation is a statistically significant predictor of devaluation and of a measure of exchange market pressure during the current crisis we define the period of the global financial shock as running from late 2008 to early 2009 which probably explains why we find stronger results than earlier papers such as obstfeld et al 2009 2010 and rose and spiegel 2009a b 2010 2011 which use annual data

democracy and national economic performance the preference for stability appear to arise because democracies ameliorate the effects of social cleavages another mechanism that might explain democratic stability when growth and volatility are jointly examined democracies reveal highly favorable economic results oes democracy affect national economic performance and if so how no question is more central to the study of political economics almost all previous work on democracy and economic performance has focused exclusively on growth rates with contradictory and confusing results in this article we argue that to reveal the impact of democratic institutions on economic performance scholars must consider two dimensions of economic performance growth rate and volatility we begin with a novel hypothesis economic policy in democracy is risk avoiding relative to policy in nondemocracies 1 because voters are riskaverse they penalize incumbent governments for economic volatility and democratic governments respond accordingly in nondemocracies we posit that elites are more likely to seek risk that voters would reject consequently autocracies produce systematically more economic volatility than

resistance to reform status quo bias in the presence of individual specific uncertainty comment why do governments so often fail to adopt policies which economists consider to be efficiency enhancing our answer to this question relies on uncertainty regarding the distribution of gains and losses from reform we show that there is a bias towards the status quo and hence against efficiency enhancing reforms whenever some of the individual gainers and losers from reform cannot be identified beforehand there are reforms which once adopted will receive adequate political support but would have failed to carry the day ex ante the argument does not rely on risk aversion irrationality or hysteresis due to sunk costs jel d72 f13 why do governments so often fail to adopt policies that economists consider to be efficiency enhancing this is one of the fundamental questions of political economy the answer usually relies on what may be

immigration policy and counterterrorism abstract in a developing country terrorists recruit and allocate their capital skilled labor and unskilled labor between domestic and foreign targets domestic targets require less skilled labor than foreign targets under various strategic scenarios we show how countermeasures against the different terrorist inputs alter the amount and mix of targets as well as how skilled and unskilled immigration quotas by a targeted foreign country affect this mix of attacks we find that increases in skilled labor quotas generally reduce terrorist attacks in the foreign country especially when the terrorists reside in a skill scarce country a number of different strategic scenarios including leader follower are investigated

intimidation linking negotiation and conflict challenger demands a resource from defender in each period challenger chooses whether to attack if attacked defender chooses whether to concede the resource forever each player might be committed to ghting until victory before con ict begins defender can make nitely many offers con ict begins if challenger rejects all offers in equilibrium all offers except the last are unacceptable negotiation cannot eliminate con ict because a larger offer makes con ict increasingly attractive for challenger if negotiation fails prolonged con ict can happen in equilibrium even when uncertainty is vanishingly small we provide comparative statics regarding the probability and length of con ict

potential pitfalls in determining multiple structural changes with an application to purchasing power parity we investigate the empirical performance of the bai and perron multiple structural change tests and show that the use of their critical values may cause severe size distortions in persistent series to correct these size distortions while maintaining a good power we implement the bai structural change test and extend it in two directions developing a new procedure to choose the number of breaks and a restricted version that specifically models breaks that imply mean or trend reversion using our new methodologies we reconcile the results of unit root tests with those of tests for structural change when testing for long run purchasing power parity

symposium on democracy and development academic fashions often follow the public political mood in a period when euphoric public commentators have announced the end of history in the triumph of capitalist democracy one sees an increasing number of scholarly studies attempting to show often on the basis of crosscountry statistical evidence and a bit of wishful thinking a positive effect of democracy on development it is in this context refreshing to see the agnostic results reported by adam przeworski and fernando limongi in their paper on the basis of their review of the theoretical arguments and statistical studies they conclude rather bluntly we do not know whether democracy fosters or hinders economic growth their brief but fairly exhaustive examination of the various statistical studies of the last few decades shows the studies to be hopelessly inconclusive and beset with serious methodological problems at the analytical level they argue that it is not at all clear if democracy with its slow empowerment of the less wealthy secures growth fostering capitalist property rights better than dictatorships democracies may actually be more susceptible to pressures for immediate consumption and other particularistic demands that may hamper long run investment on the other hand authoritarian rulers who have the capacity to resist such pressures may instead be self aggrandi zing plundering the surplus of the economy in fact authoritarian regimes may come in different kinds some deriving their legitimacy from providing order and stability some from rapid growth sah 1991 has argued that authoritarian regimes exhibit a larger variance in economic performance than democracies

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

holding on ethnic divisions political institutions and the duration of economic declines abstract we analyze the duration of large economic declines and provide a theory of delayed recovery we show theoretically that uncertain post recovery incomes lead to a commitment problem which limits the possibility of cooperation in ethnically heterogeneous countries strong constraints on the executive solve this problem by reducing the uncertainty associated with cooperative behavior we test the model using standard data on linguistic heterogeneity and detailed data on ethnic power configurations our findings support the central theoretical prediction countries with more constrained political executives experience shorter economic declines the effect is large in ethnically heterogeneous countries but virtually non existent in homogeneous societies our main results are robust to a variety of perturbations regarding the estimation method the estimation sample measures of heterogeneity and measures of institutions

institutions versus policies a tale of two islands recent work emphasizes the primacy of differences in countries colonially bequeathed property rights and legal systems for explaining differences in their subsequent economic development barbados and jamaica provide a striking counter example to this long run view of income determination both countries inherited property rights and legal institutions from their english colonial masters yet experienced starkly different growth trajectories in the aftermath of independence from 1960 to 2002 barbados gdp per capita grew roughly three times as fast as jamaica s consequently the income gap between barbados and jamaica is now almost five times larger than at the time of independence since their property rights and legal systems are virtually identical recent theories of development cannot explain the divergence between barbados and jamaica differences in macroeconomic policy choices not differences in institutions account for the heterogeneous growth experiences of these two caribbean nations

trade as a threshold variable for multiple regimes abstract this paper employs the data sorting method developed by hansen econometrica 68 2000 575 which allows the data to endogenously select regimes using different variables it is shown that openness as measured by the trade share to gdp is a threshold variable that can cluster middle income countries into two distinct regimes that obey different statistical models our result suggests that openness may not be as crucial in the growth process of low and high income countries but it is instrumental in identifying middle income countries into high and low growth groups

empirics of hills plateaus mountains and plains a markov switching approach to growth abstract most economic growth research has been aimed at explaining cross country differences in average growth rates however it is well known that growth experiences differ over time within a country almost as much as they differ among countries this paper builds on pritchett s 2000 pritchett lant understanding patterns of economic growth searching for hills among plateaus mountains and plains world bank economic review may 2000 14 2 221 250 observation that the growth process can be thought of as transitions between different growth regimes and proposes a framework for systematic analysis of such regimes and the dynamics of the transitions i estimate a markov switching regression to characterize four distinct growth regimes and transitions between them the results show that countries switch among regimes of stable growth miracle catch up stagnation and crisis with the transition probabilities determined by the quality of institutions better institutions appear to improve long run growth by making episodes of fast growth more persistent low average growth rates in countries with weak institutions are a result of these countries spending more time in stagnation regimes rather then being incapable of fast growth at all weak institutions do not rule out growth takeoffs but limit their sustainability the approach directs attention to shifts in growth performance and highlights the fact that identical average growth rates can mask very distinct growth paths

the long run relationship between trade and population health evidence from five decades in recent years the increase in international trade has sparked a debate about the impact of international trade on population health to date however there has been very little econometric research on the relationship between these two variables this paper examines the long run relationship between trade openness and population health for a sample of 74 countries over five decades from 1960 to 2010 using panel time series techniques it is shown that international trade in general has a robust positive long run effect on health as measured by life expectancy and infant mortality this effect tends to be greater in countries with lower development levels higher taxes on income profits and capital gains and less restrictive business and labour market regulations

participatory politics social cooperation and economic stability few would doubt the proposition that political institutions matter for economic development yet robust generalizations and systematic evidence on how exactly they do so are lacking in this paper attention is drawn to regularity in the cross national data that has received little attention to date participatory political regimes are associated with significantly lower levels of aggregate economic instability after presenting some of the evidence it is speculated that the reason has to do with the propensity of democracy to moderate social conflict and induce compromise three distinct arguments as to why this may be the case are presented

income smoothing and consumption smoothing one way that risk averse households protect consumption levels is to borrow and use insurance mechanisms another way common in low income economies is to diversify economic activities and make conservative production and employment choices households thus tend toward limiting exposure only to shocks that can be handled with available credit and insurance typically both types of mechanisms are studied independently but much more can be learned by studying them together first we obtain a more complete picture of risks costs and insurance possibilities second it opens the way to considering biases in standard tests of credit and insurance

financial institutions and markets across countries and over time the updated financial development and structure database this article introduces the updated and expanded version of the financial development and structure database the database includes indicators on the size efficiency and stability of banks nonbank financial institutions and equity and bond markets over 1960 2007 it also contains indicators of financial globalization

structural differences in economic growth an endogenous clustering approach this article addresses heterogeneity in determinants of economic growth in a data driven way instead of defining groups of countries with different growth characteristics a priori based on for example geographical location we use a finite mixture panel model and endogenous clustering to examine cross country differences and similarities in the effects of growth determinants applying this approach to an annual unbalanced panel of 59 countries in asia latin and middle america and africa for the period 1971 2000 we can identify two groups of countries in terms of distinct growth structures the structural differences between the country groups mainly stem from different effects of investment openness measures and government share in the economy furthermore the detected segmentation of countries does not match with conventional classifications in the literature

the voracity effect abstract we analyze an economy that lacks a strong legal political institutional infrastructure and is populated by multiple powerful groups powerful groups dynamically interact via a fiscal process that effectively allows open access to the aggregate capital stock in equilibrium this leads to slow economic growth and a voracity effect by which a shock such as a terms of trade windfall perversely generates a more than proportionate increase in fiscal redistribution and reduces growth we also show that a dilution in the concentration of power leads to faster growth and a less procyclical response to shocks jel f43 o10 o23 o40

china s optimal stockpiling policies in the context of new oil price trend abstract optimizing the size of oil stockpiling plays a fundamental role in the process of making national strategic petroleum reserve spr policies there have been extensive studies on the operating strategies of spr however previous literatures have paid more attention to a booming or stable international oil market while few studies analyzed the impact of a long term low oil price on spr policy as a supplement this paper extends a static model to study china s optimal stockpiling policy under different oil price trends and in response to different current oil prices a new variable fc which demonstrates the appreciation and depreciation of the reserved oil economic value has been taken into account to assess the optimal size of spr in this paper a more multi perspective of view is provided to consider the policies of china s spr especially under the different trend of international oil price fluctuations

a strategic analysis of the war against transnational terrorism abstract we study a two stage game in which a transnational terrorist organization interacts with an arbitrary number of countries that may differ in their political or economic power their military effectiveness the benefit from cooperating against terrorism and the value they assign to damage only a subset of countries that emerges endogenously takes proactive measures to fight the terrorist while all countries incur defensive expenditures to protect their soil we characterize analytically the pure strategy subgame perfect equilibrium of the game and show how the equilibrium strategies depend on the key model parameters we provide an algorithm to find the endogenous set of cooperating countries based on their benefit from cooperation and their political economic power

the high price of dematerialization a dynamic panel data analysis of material use and economic recession abstract dematerialization at the national level occurs almost exclusively during periods of economic recession or low growth while recession is not a sustainable strategy to curb environmental impact such periods may offer important insights on the possibilities of reducing material use economic recession research has focused on the interactions between macroeconomic and financial variables with little systematic research dedicated to uncovering how resource use develops during periods of recession using a dynamic panel model we investigate whether and to what extent material use in a sample of 150 economies between 1970 and 2010 was affected by recession and low growth recession occurred most frequently and in more than two thirds of all countries during the 1980s and the 1990s in the 2000s more than half of the recessions occurred during the financial crisis of 2008 periods of recession were significantly and negatively correlated with material use they tended to coincide with dematerialization material use decreased in recession years but the significant correlations with growth in material use became weaker as growth rates increased construction minerals and metals used to build stocks of manufactured capital reacted more strongly to economic fluctuations than the throughput dominated flows of biomass and fossil fuels we conclude that the systematic link between recession and dematerialization can become policy relevant if the mechanisms causing reductions in material use during these periods are identified

linking conflict to inequality and polarization in this paper we study a behavioral model of conflict that provides a basis for choosing certain indices of dispersion as indicators for conflict we show that a suitable monotone transform of the equilibrium level of conflict can be proxied by a linear function of the gini coefficient the herfindahl hirschman fractionalization index and a specific measure of polarization due to esteban and ray jel classification d74 d31

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

convergence clubs and subsistence economies abstract this paper focuses on one possible explanation for the empirical evidence of a income convergence among the world s poorest countries and among its wealthiest countries and b income divergence among most of the remaining countries the model incorporates the assumption of subsistence consumption into the neoclassical exogenous growth model yielding outcomes that are consistent with the convergence divergence empirical evidence while subsistence consumption can lead to negative saving and disaccumulation of capital it can also coincide with positive saving and accumulation of capital the model predicts that the poorer the country the lower its saving rate a result that also appears to be borne out by the evidence provided here

terrorism key assets and critical infrastructures to protect or to rebuild that is the question both the choice between stick and carrot and the tension between control and preservation of civil liberties characterize the policy debate over counterterrorism arguing for the carrot and preservation of civil liberties viewpoint frey and rohner def peace econ 18 3 245 252 2007 propose strategic reconstruction as an alternative to protection our paper provides a comparative analysis of these two policies first we study the rationality of the public s expectations and we show that credible strategic reconstruction may deter terrorist attacks next we derive conditions under which strategic reconstruction is more efficient than protection finally we show that strategic reconstruction may reinforce the efficiency of protection

terror networks and trade does the neighbor hurt abstract this paper studies how network related terrorism redistributes trade flows across countries including those countries that are not a direct source of terror we first develop a game theoretical framework with imperfect information on the spatial location of transnational terrorism to show how the resulting security measures produce a non monotonic effect on the distribution of trade across countries neighbors adjacent to terror even when they do not source it have trade reduced through enhanced security measures while countries farther away benefit from those security measures second to empirically assess the distortional effects of terrorism on trade we first estimate the structural gravity equation derived from our theory then armed with the estimates of the partial effect of neighbor terror on bilateral trade we perform a counterfactual experiment and confirm the non monotonic general equilibrium effect of neighbor terror on trade

macroeconomic volatility and welfare in developing countries an introduction macroeconomic volatility both a source and a reflection of underdevelopment is a fundamental concern for developing countries their high aggregate instability results from a combination of large external shocks volatile macroeconomic policies microeconomic rigidities and weak institutions volatility entails a direct welfare cost for risk averse individuals as well as an indirect one through its adverse effect on income growth and development this article provides a brief overview of the recent literature on macroeconomic volatility in developing countries highlighting its causes consequences and possible remedies it then introduces the contributions of a recent conference on the subject sponsored by the world bank and pompeu fabra university barcelona

do banking crises improve democracy we study the relationship between banking crises and the level of democracy we use an event study method on a sample of up to 129 countries over the period 1975 2010 featuring 94 systemic banking crises we find that banking crises are followed by an improvement in democracy and report evidence suggesting that the relation may be causal the bulk of the improvement takes place between 3 and 10 years after the banking crisis the impact of a banking crisis is greater in non democratic countries and when the banking crisis is severe we explain this finding by the fact that banking crises create windows of opportunity to contest autocratic regimes

institutional causes macroeconomic symptoms volatility crises and growth countries that have pursued distortionary macroeconomic policies including high inflation large budget deficits and misaligned exchange rates appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period does this reflect the causal effect of these macroeconomic policies on economic outcomes one reason to suspect that the answer may be no is that countries pursuing poor macroeconomic policies also have weak institutions including political institutions that do not constrain politicians and political elites ineffective enforcement of property rights for investors widespread corruption and a high degree of political instability this paper documents that countries that inherited more extractive institutions from their colonial past were more likely to experience high volatility and economic crises during the postwar period more specifically societies where european colonists faced high mortality rates more than 100 years ago are much more volatile and prone to crises based on our previous work we interpret this relationship as due to the causal effect of institutions on economic outcomes europeans did not settle and were more likely to set up extractive institutions in areas where they faced high mortality once we control for the effect of institutions macroeconomic policies appear to have only a minor impact on volatility and crises this suggests that distortionary macroeconomic policies are more likely to be symptoms of underlying institutional problems rather than the main causes of economic

are developing countries catching up this paper reviews catch up growth in various parts of the world especially in the twentieth century with a particular focus on what this implies for the global south in 1950 us per capita national income adjusted for purchasing power was nearly five times the world average since then western europe and japan have closed their per capita income gaps with the usa east asia south asia and some other developing countries have also started to close their gaps with the west in recent decades thus after well over a century of growing international economic disparities or divergence the world has witnessed an era of uneven catching up with the north in parts of the south since the mid twentieth century

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

testing substitution between private and public storage in the u s oil market a study on the u s strategic petroleum reserve abstract the u s strategic petroleum reserve spr was established in 1975 to mitigate major oil supply disruptions and to deter the use of energy as a geopolitical weapon however policies towards the utilization of strategic oil stocks have varied under different presidencies and the spr has often not been used in sufficient quantity or soon enough to avoid the negative economic consequences that can follow oil supply outages economic theory suggests that the existence of public stockpiles of commodities will alter inventory management practices of private market participants this paper models private crude oil storage in the united states and estimates the private storage response to presidential announcements regarding the spr we investigate the incidence of different kinds of announcement events including releases and test sales from the spr announced changes in fill rates and changes of presidency and how these events impact private land based storage in the united states by region padd as well floating storage we find significant substitution between private and public stocks for crude oil and find that announcement events are associated with observable changes in private inventory levels with implications for public policy choices and geopolitical strategies

do weak institutions prolong crises on the identification characteristics and duration of declines during economic slumps this paper studies periods of prolonged contractions in output per capita in a sample of 145 countries from 1950 to 2014 economic slumps are defined as abrupt interruptions of a period of growth by several regime switches slumps start with a sharp contraction along with a trend break which is followed by another switch when growth stabilizes again the paper then analyzes the correlates of these slumps focusing on the length and depth of the contraction from the beginning of the slump to its trough the results establish three new stylized facts i weak political institutions predate crises whereas political reforms tend to follow them ii the length and depth of economic declines are robustly correlated with executive constraints and ethnic heterogeneity and iii there is a robust interaction between these two variables suggesting that institutions constraining leaders are important for stabilizing growth this is particularly relevant for sub saharan africa where politics are often ethnic and decision makers are comparatively unconstrained

hiding in plain sight using signals to detect terrorists this paper studies the interaction between a governmental security agency as the transportation security agency or the immigration and naturalization service and a terrorist organization like al qaeda the governmental agency wants to stop the terrorists but first must infer whether a visa applicant or an airline passenger is a terrorist on the basis of some observable signal the terrorist organization s objective is to get past security to commit murder and mayhem we derive the equilibrium strategy for this signaling model and evaluate specific anti terrorist policies as the creation of the new homeland security agency and increased airport security screening

towards a new early warning system of financial crises abstract this paper develops a new early warning system ews model based on a multinomial logit model for predicting financial crises it is shown that commonly used ews approaches which use binomial discrete dependent variable models are subject to what we call a post crisis bias this bias arises when no distinction is made between tranquil periods when economic fundamentals are largely sound and sustainable and crisis post crisis periods when economic variables go through an adjustment process before reaching a more sustainable level or growth path we show that applying a multinomial logit model which allows distinguishing between more than two states is a valid way of solving this problem and constitutes a substantial improvement in the ability to forecast financial crises the empirical results reveal that for a set of 20 open emerging markets for the period 1993 2001 the model would have correctly predicted a large majority of crises in emerging markets

do all countries grow alike abstract this paper investigates the driving forces of output change in 77 countries during the period 1970 2000 a flexible modeling strategy is adopted that accounts for i the inefficient use of resources and ii different production technologies across countries the proposed model can identify technical efficiency and input change for each of three endogenously determined regimes membership in these regimes is estimated rather than determined ex ante this framework enables explorations into the determinants of output growth and convergence issues in each regime

exchange market mayhem the antecedents and aftermath of speculative attacks exchange market mayhem the antecedents and aftermath of speculative attacks this paper evaluates the causes and consequences of episodes of turbulence in foreign exchange markets using data from 1959 through 1993 for twenty oecd countries we consider the antecedents and aftermath of devaluations and revaluations flotations fixings and speculative attacks which may not be successful we find that realignments of fixed exchange rates are alike devaluations are preceded by political instability budget and current account deficits and fast growth of money and prices revaluations are mirror images of devaluations speculative attacks resemble devaluations but money growth and inflation are more endemic and there is no last minute attempt to tighten monetary policy in contrast few consistent correlations link regime transitions like flotations or fixings to macroeconomic or political variables transitions between exchange rate regimes are largely idiosyncratic and are neither consistently provoked ex ante by systematic imbalances nor typically justified ex post by subsequent changes in policy we conclude that there are no clear early warning signals of many speculative attacks and no easy solutions for policy makers barry eichengreen andrew k rose and charles wyplosz

business cycle fluctuations large macroeconomic shocks and development aid abstract we examine the cyclical properties of development aid using bilateral data for 22 donors and 113 recipients during 1970 2005 we find that bilateral aid flows are on average procyclical with respect to the business cycle in both donor and recipient countries while aid outlays contract sharply during severe downturns in donor countries they rise steeply when aid receiving countries experience large adverse shocks our findings suggest that development aid may play an important cushioning role in developing countries but only during times of severe macroeconomic stress our results are robust to alternate definitions of aid flows specifications and estimation techniques

are the poor less well insured evidence on vulnerability to income risk in rural china the authors test how well consumption is insured against income risk in a panel of sampled households in rural china they estimate the risk insurance models by generalized method of moments treating income and household size as endogenous insurance exists for all wealth groups although the hypothesis of perfect insurance is universally rejected those in the poorest wealth decile are the least well insured with 40 percent of an income shock being passed on to current consumption by contrast consumption by the richest third of households is protected from almost 90 percent of an income shock the extent of insurance in a given wealth stratum varies little between poor and nonpoor areas

macroeconomic stability and the distribution of growth rates it is often argued that macroeconomic instability can form a binding constraint on economic growth drawing on a new index of stability threshold estimation is used to divide developing economies into two growth regimes depending on a threshold level of stability for the more stable group of countries the output benefits of investment are greater conditional convergence is faster and measures of institutional quality have more explanatory power suggesting that instability forms a binding constraint for the less stable group macroeconomic stability is also shown to dominate several other candidates for identifying distinct growth regimes

testing for country heterogeneity in growth models using a finite mixture approach we define a bivariate mixture model to test whether economic growth can be considered exogenous in the solovian sense for this purpose the multivariate mixture approach proposed by alfo and trovato is applied to the bernanke and gurkaynak extension of the solow model we find that the explanatory power of the solow growth model is enhanced since growth rates are not statistically significantly associated with investment rates when cross country heterogeneity is considered moreover no sign of convergence to a single equilibrium is found copyright 2008 john wiley sons ltd

on the welfare cost of economic fluctuations in developing countries macroeconomic fluctuations are much stronger in developing countries than in the united states yet while a large literature debates the welfare cost of economic fluctuations in the united states it remains an open question how large that cost is in developing countries using several models we provide such a measure we find that the welfare cost of consumption volatility per se is far from trivial and averages a substantial multiple of the corresponding u s estimate moreover in many poor countries the welfare gain from eliminating volatility may in fact exceed the welfare gain from an additional percentage point of growth forever

testing for convergence clubs in income per capita a predictive density approach the article proposes a technique based on the predictive density of the data conditional on the parameters of the model to jointly tests for groups of unknown size in a panel and to estimate the parameters of each group the procedure is applied to the problem of identifying convergence clubs in scaled income per capita data the steady state distribution of european regional data clusters around four poles of attraction with different economic features the distribution of income per capita of oecd countries has two poles of attraction and each group clearly identifiable economic characteristics we share the uncommonness of being different j p roche

policy volatility institutions and economic growth abstract in this paper we present evidence that policy volatility exerts a strong and direct negative impact on growth using data for 93 countries we construct measures of policy volatility based on the standard deviation of the residuals from country specific regressions of government consumption on output undisciplined governments that implement frequent and large changes in government spending unrelated to the state of the business cycle generate lower economic growth we employ both instrumental variables and panel estimation to address concerns of omitted variables and endogeneity a 1 standard deviation increase in policy volatility reduces long term economic growth by about 0 74 in the panel regressions and by more than 1 percentage point in the cross section

the cost of business cycles under endogenous growth robert e lucas jr argued that the welfare gains from reducing aggregate consumption volatility are negligible subsequent work that revisited his calculation continued to find small welfare benefits further reinforcing the perception that business cycles do not matter this paper argues instead that fluctuations can affect welfare by affecting the growth rate of consumption i show that fluctuations can reduce growth starting from a given initial consumption which can imply substantial welfare effects as lucas himself observed empirical evidence suggests the welfare effects are likely to be substantial about two orders of magnitude greater than lucas original estimates

the simultaneous evolution of growth and inequality research on inequality and growth can be divided into two strands one deriving from kuznets and lewis has tried to identify a mechanistic relationship between growth or level of income and inequality the other has tried to find causal explanations of growth and inequality treating each independently in this paper we draw from both strands to test whether growth and inequality are the joint outcomes of other variables and processes we find that simultaneous examination of growth and inequality yields significantly different results and has different consequences for policy from previous independent studies the empirical literature on growth and inequality can be divided into two broad strands one following the pioneering work of kuznets and lewis is motivated by the pessimistic conjecture that the process of growth and development somehow requires increasing inequality at least in the early stages this has led to many efforts to identify a mechanical relationship between the level of development and inequality anand and kanbur 1993 or to determine whether faster growth requires higher or lower inequality the second strand has sought to identify the causal factors influencing the evolution of growth and inequality independently this research has looked either at growth for example barro and sala i martin 1995 or at inequality li et al 1997 but has not tried to identify those factors that might simultaneously influence both growth and inequality 2 thus the literature that looks simultaneously at growth and inequality descending most notably from kuznets 1955 relates them in a mechanistic manner that ignores or minimises the role of other causal factors including policy while the literature that incorporates other causal factors including policies looks independently at growth and inequality neither approach is particularly convincing from a theoretical standpoint the evolution of growth and inequality must surely be the outcome of similar processes in addition neither approach is particularly useful for the policy maker who needs to balance the impact of policies on both growth and distribution in this paper we investigate whether growth and inequality are simultaneously determined and if so whether or not they are subject to

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

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

world crude oil and natural gas a demand and supply model abstract this paper examines world markets for crude oil and natural gas over the period 1918 1999 it analyzes the time series properties of output and prices and estimates demand and supply elasticities during 1918 1973 and 1973 1999 oil and gas prices were stable during the first period they became volatile afterwards reflecting deep changes in the market structure following the oil shock in 1973 demand price elasticities were too low however demand income elasticities were high supply price elasticities were also too low the elasticity estimates help to explain the market power of the oil producers and price volatility in response to shocks and corroborate elasticity estimates in energy studies

simultaneity and structural change in u s meat demand an inverse of the almost ideal demand system the iaids is developed in order to test the endogeneity of prices and quantities in the u s meat demand system the iaids has all the desirable theoretical properties of the aids except aggregation from the micro to the market level using annual data both prices and quantities appear to be endogenous within the entire meat market including livestock production costs and technical change indicators as instruments eliminates evidence of a mid 1970s demand change

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

real income stagnation of countries 1960 2001 abstract this paper examines the phenomenon of real income stagnation in which real income growth is uninterruptedly negligible or negative for a sizable sequence of years we analyse data for four decades from a large cross section of countries real income stagnation is a conceptually distinct phenomenon from low average growth and other features of the growth sequence that have been previously considered we find that real income stagnation has affected a significant number of countries 103 out of 168 and resulted in substantial income loss countries that suffered spells of real income stagnation were more likely to be poor in latin america or sub saharan africa conflict ridden and dependent on primary commodity exports stagnation is also very likely to persist over time countries that were afflicted with stagnation in the 1960s had a likelihood of 75 per cent of also being afflicted with stagnation in the 1990s
