financial development income inequality and the redistributive effects of monetary policy abstract how should financial systems be designed to limit income inequality does the redistributive impact of inflation depend on the extent of financial development should optimal monetary policy vary across countries with different levels of financial development in order to address these questions we develop a monetary growth production model with heterogeneous agents in our economy optimal policy needs to weigh the effects of policy across two groups capital owners and individuals who hold liquid assets in this environment we compare various economies that are identical in every aspect except for their level of financial development interestingly we generally find that economies at the highest stages of financial development economies in which money bonds and claims to capital are traded experience the highest amount of capital formation and social welfare as long as inflation is low yet regardless of the extent of financial development there are generally redistributive consequences from inflation moreover the model tends to predict that economies with relatively small stock markets produce the highest levels of income inequality empirical work examining the role of money growth and the implications of financial development across countries is consistent with predictions from the model

the origins of ethnolinguistic diversity this study explores the determinants of ethnolinguistic diversity within as well as across countries shedding light on its geographic origins the empirical analysis conducted across countries virtual countries and pairs of contiguous regions establishes that geographic variability captured by variation in regional land quality and elevation is a fundamental determinant of contemporary linguistic diversity the findings are consistent with the proposed hypothesis that differences in land endowments gave rise to location specific human capital leading to the formation of localized ethnicities jel j15 j24 z13

inflation growth and wage policy a brazilian perspective abstract a growth inflation model based on recent brazilian experience is developed the paper focuses on brazilian compulsory wage policy in order to analyse current stabilization policy issues in this context it is argued that orthodox stabilization policies as exemplified by an autonomous reduction in the rate of monetary growth implies both a temporary and a permanent decrease in output growth if the wage formula as in brazil provides for lagged price indexation the idea of promoting stabilization through full wage indexation is also examined

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

investment and capacity choice under uncertain demand this paper extends the real options literature by discussing an investment problem where a firm has to determine optimal investment timing and optimal capacity choice at the same time under conditions of irreversible investment expenditures and uncertainty in future demand after the project is installed with a certain maximum capacity this capacity is fixed as an upper boundary to the output and cannot be adjusted later on it turns out that in the framework of this once and for all decision uncertainty in future demand leads to an increase in optimal installed capacity but on the other hand it causes investment to be delayed to an extent that even small uncertainty makes waiting and accumulation of further information the optimal decision for large ranges of demand limiting the capacity which may be installed weakens this extreme effect of uncertainty

a theory of political transitions we develop a theory of political transitions inspired by the experiences of western europe and latin america nondemocratic societies are controlled by a rich elite the initially disenfranchised poor can contest power by threatening revolution especially when the opportunity cost is low for example during recessions the threat of revolution may force the elite to democratize democracy may not consolidate because it is redistributive and so gives the elite an incentive to mount a coup highly unequal societies are less likely to consolidate democracy and may end up oscillating between regimes and suffer substantial fiscal volatility

real options with constant relative risk aversion real options problems have recently attracted much attention worldwide one such problem is how to deal with claims on non traded assets often there is another traded asset which is correlated to the non traded asset and this traded asset is used as a proxy for hedging purposes we introduce a second non traded log brownian asset into the well known merton investment model with power law utility the investor has a claim on units of the non traded asset and the question is how to price and hedge this random payoff the presence of the second brownian motion means that we are in the situation of incomplete markets we propose an approximation to the solution for the optimal reservation price and hedge which is accurate when the position is small in comparison to wealth the resulting loss when a suboptimal proxy strategy is followed is shown to be approximately quadratic in 1

malaria suitability urbanization and persistence evidence from china over more than 2000 years abstract we show that the climatic potential for plasmodium falciparum malaria transmission constituted a locational fundamental that influenced the spatial distribution of urbanization since the early start of the southward expansion of the han chinese around 200 bce this effect is still detectable in today s distribution of urbanization and economic activity even though the risk of malaria falciparum has been successfully eliminated we do not find any indication of convergence between high and low malaria potential regions after eradication our identification strategy relies on a climate based measure of plasmodium falciparum malaria transmission intensity which is fitted to experimental data on mosquito and parasite development from laboratory studies this measure is exogenous with respect to human population densities

disease and development the effect of life expectancy on economic growth we exploit the major international health improvements from the 1940s to estimate the effect of life expectancy on economic performance we construct predicted mortality using preintervention mortality rates from various diseases and dates of global interventions predicted mortality has a large impact on changes in life expectancy starting in 1940 but no effect before 1940 using predicted mortality as an instrument we find that a 1 percent increase in life expectancy leads to a 1 7 2 percent increase in population life expectancy has a much smaller effect on total gdp however consequently there is no evidence that the large increase in life expectancy raised income per capita

impact of financial crises on poverty in developing world an empirical approach in this paper we adopt a cross country perspective to analyze the short term effects of currency banking and debt crises on poverty we employ multivariate fixed effects panel data analysis in order to examine whether and to what extent different types of financial crises impact the poverty headcount ratio and the poverty gap as measured by the world bank our findings suggest that out of the three categories of financial crises we identify it is currency crises that most significantly exacerbate both the incidence and depth of poverty in the short run we find evidence that banking crises are associated with an increase in the depth of poverty but not the incidence however this effect tends to be short lived while our analysis shows no direct effect of sovereign debt crises on short term poverty

optimal investment under operational flexibility risk aversion and uncertainty traditional real options analysis addresses the problem of investment under uncertainty assuming a risk neutral decision maker and complete markets in reality however decision makers are often risk averse and markets are incomplete we confirm that risk aversion lowers the probability of investment and demonstrate how this effect can be mitigated by incorporating operational flexibility in the form of embedded suspension and resumption options although such options facilitate investment we find that the likelihood of investing is still lower compared to the risk neutral case risk aversion also increases the likelihood that the project will be abandoned although this effect is less pronounced finally we illustrate the impact of risk aversion on the optimal suspension and resumption thresholds and the interaction among risk aversion volatility and optimal decision thresholds under complete operational flexibility

committees as substitutes for commitment in this article policies are negotiated in a committee by playing a dynamic voting game with an endogenous default or status quo policy i show that joining a committee by maintaining a strong agenda setting power is a way for a decision maker to commit to a policy that in absence of committees is not time consistent the disciplinary role of the endogenous status quo and the heterogeneity of preferences within the committee are two crucial ingredients to obtain this result as a motivating example this article focuses on the time consistency of monetary policy

disease and development a reply to bloom canning and fink bloom canning and fink 2014 argue that the results in acemoglu and johnson 2006 2007 are not robust because initial level of life expectancy in 1940 should be included in our regressions of changes in gdp per capita on changes in life expectancy we assess their claims controlling for potential lagged effects of initial life expectancy using data from 1900 employing a nonlinear estimator suggested by their framework and using information from microeconomic estimates on the effects of improving health there is no evidence for a positive effect of life expectancy on gdp per capita in this important historical episode this abstract was borrowed from another version of this item

disease and development revisited acemoglu and johnson 2007 present evidence that improvements in population health do not promote economic growth we show that their result depends critically on the assumption that initial health has no causal effect on subsequent economic growth we argue that such an effect is likely primarily because childhood health affects adult productivity in our augmented model which includes initial health the instrumental variable proposed by acemoglu and johnson has no significant predictive power for improvements in health and does not identify the effect of contemporaneous improvements in health on economic growth this abstract was borrowed from another version of this item

hysteresis due to irreversible exit addressing the option to mothball abstract this paper analyses the following hitherto understudied feature in real switching options a firm has a mothballing option and an option to permanently abandon if the firm finds itself in an operating mode with a price just above the abandonment threshold it is unclear whether to exercise the abandonment option or to exercise the mothballing option if the price goes down the firm may exit but surprisingly if it goes up it may mothball we find that two different strategies could be optimal one where mothballing is not a viable option and one where mothballing does occur in the latter case a hysteresis region arises in which the firm produces at a loss while a further price decrease induces exit and a sufficient price increase results in the firm entering the mothballing stage mothballing being optimal requires sufficiently large values of the price trend and the uncertainty parameter

mass democracy the real reason that brazil ended inflation summary populism and expanded democratic participation often have been painted as the enemy of sane macroeconomics yet brazil s experience suggests possibly benign implications of stable mass democracy for national economic management in developing countries prior to 1930 agrarian elites ruled brazil as political participation gradually expanded policymakers elaborated the regulatory framework of import substituting industrialization isi isi not only generated strong growth but also chronically high and volatile inflation with costs falling most heavily on the disenfranchised a poor majority the advent of mass democracy in the mid 1980s gave the poor a political voice for the first time and plausibly was the crucial cause for the demise of hyperinflation a decade later

prices wages and poverty in rural india what lessons do the time series data hold for policy abstract looking back over 40 years or so one finds that higher relative prices of food in india have typically been associated with higher poverty incidence and lower real agricultural wages this has not gone unnoticed by critics of agricultural policy reform in india who have argued that reform could permanently increase poverty by permanently raising food prices relative to non food prices however a number of other observations about the time series evidence cast doubt on this interpretation the correlation with poverty as it is being measured is not a distributional effect yet it is very unlikely that the rural sector as a whole could be worse off from a higher relative price of food instead the correlation with poverty can be explained by shocks to aggregate food output the correlation between food prices and real wages can be explained by changes in farm yields and inflation critics of reform appear to have misread the lessons for policy but these data cannot be used to support the view that higher food prices due to policy reform will on their own reduce rural poverty

growth and violence argument for a per capita measure of civil war the economics literature typically uses counts of casualties as a measure of conflict intensity despite the fact that the units of observation vary considerably in population size when analysing the impact of conflict on economic growth the use of counts relies on the assumption that a given number of casualties affects large and small populations in the same way using within and between country evidence this paper demonstrates that this standard assumption can be rejected a per capita model of conflict intensity that captures local effects of violence provides a more consistent empirical framework for both between country and within country studies

conflict and distribution abstract we develop a behavioral model that links the level and pattern of social conflict to the societywide distribution of individual characteristics the model can be applied to groups that differ in characteristics such as wealth ethnicity religion and political ideology we settle questions of existence and uniqueness of conflict equilibrium conflict is seen to be closely connected with the bimodality of the underlying distribution of characteristics however in general the conflict distribution relationship is nonlinear and surprisingly complex our results on conflict patterns also throw light on the phenomena of extremism and moderation journal of economic literature classification numbers d63 d72 d74

food prices and poverty do higher food prices help or hinder poverty reduction despite much debate existing research has almost solely relied on simulation models to address this question in this paper world bank poverty estimates are used to systematically test the relationship between changes in poverty and exogenous changes in real domestic food prices the paper uncovers indicative evidence that increases in food prices are associated with reductions in poverty not increases a likely empirical explanation is the relatively strong agricultural supply and wage responses to food price increases and the fact that the majority of the world s poor still heavily rely on agriculture or agriculture related activities to earn a living

early life health and cognitive function in old age child health in the united states improved dramatically over the twentieth century data from the national center for health statistics indicate the infant mortality rate was 23 times greater in 1900 than in 2004 the mortality rate of one to four year old children although lower in absolute terms had a larger proportionate decline the value in 1900 was 66 times that in 2004 the proximate cause of the mortality decline was a reduction in infectious disease between 1900 and 1998 the percentage of deaths of children age 1 to 19 due to infectious disease is estimated to have declined from 61 6 percent to 2 percent bernard guyer et al 2000 major causes of child death included diarrhea pneumonia and other respiratory infections diphtheria typhoid measles scarlet fever whooping cough and tuberculosis guyer et al 2000 the mortality decline was accompanied by reductions in morbidity among surviving children there were also declines in the prevalence of a host of illnesses such as hookworm and trachoma which were not deadly but which impaired children s quality of life c hoyt bleakley 2007 shannen k allen and richard d semba 2002 early life exposures to infectious disease may also have adverse effects on health and well being into old age if true then the benefits of the twentieth century decline in infectious disease in the united states are still being realized we examine whether the disease environments experienced by american children in the first half of the twentieth century are associated with their cognitive abilities at older ages we match region level historical data on mortality from a variety of infectious diseases as well as total infant mortality with information on the cognitive function of older americans followed by the health and retirement study hrs we find evidence that the burden of disease in early life measured using either mortality rates by cause or the overall infant mortality rate is significantly associated with performance on cognitive tests in old age

population and conflict medical innovations during the 1940s quickly resulted in significant health improvements around the world countries with initially higher mortality from infectious diseases experienced larger increases in life expectancy population and subsequent social conflict this cross country result is robust across alternative measures of conflict and is not driven by differential trends between countries with varying baseline characteristics a similar effect is also present within mexico initial suitability conditions for malaria varied across municipalities and anti malaria campaigns had differential effects on population growth and social conflict both across countries and within mexico increased conflict over scarce resources predominates and this effect is more pronounced during times of economic hardship specifically in countries with a poor growth record and in drought stricken areas in mexico at least during this time period a larger increase in population made social conflict more likely

inflation and the poor using polling data for 31 869 households in 38 countries and allowing for country effects the authors show that the poor are more likely than the rich to mention inflation as a top national concern this result survives several robustness checks also direct measures of improvements in well being for the poor the change in their share of national income the percentage decline in poverty and the percentage change in the real minimum wage are negatively correlated with inflation in pooled cross country samples high inflation tends to lower the share of the bottom quintile and the real minimum wage and tends to increase poverty

why have some indian states done better than others at reducing rural poverty the unevenness of the rise in rural living standards in the various states of india since the 1950s allowed the authors to study the causes of poverty they modeled the evolution of average consumption and various poverty measures using pooled state level data for 1957 91 they found that poverty was reduced by higher agricultural yields above trend growth in nonfarm output and lower inflation rates but these factors only partly explain relative success and failure in reducing poverty initial conditions also mattered states that started the period with better infrastructure and human resources with more intense irrigation greater literacy and lower infant mortality rates had significantly greater long term rates of consumption growth and poverty reduction by and large the same variables that promoted growth in average consumption also helped reduce poverty the effects on poverty measures were partly redistributive in nature after controlling for inflation the authors found that some of the factors that helped reduce absolute poverty also improved distribution and none of the factors that reduced absolute poverty had adverse impacts on distribution in other words there was no sign of tradeoffs between growth and pro poor distribution

primary commodity prices manufactured goods prices and the terms of trade of developing countries what the long run shows the authors revisit in this article the empirical foundation of the alleged secular decline in the prices of primary commodities relative to those of manufactures they use a newly constructed index of commodity prices and two modified indexes of manufactured good prices and find that from 1900 to 1986 the relative prices of all primary commodities fell on trend by 0 5 percent a year and those of nonfuel primary commodities by 0 6 percent a year they thus confirm the sign but not the magnitude of the trend implicit in the work of prebisch but even the more limited secular decline shown by their relative price indexes may be magnified by an incomplete account of quality improvements in manufactures they then show that the evolution of terms of trade of nonfuel primary commodities is not the same as that of the net barter terms of trade of non oil exporting developing countries finally they find that despite the decline that has probably occurred during the current century in the terms of trade of nonfuel primary commodities the purchasing power of total exports of these products has increased considerably similarly the fall that may have occurred after world war ii in the net barter terms of trade of developing countries seems to have been more than compensated for by the steady improvement in their income terms of trade

malaria eradication and economic outcomes in sub saharan africa evidence from uganda this study evaluates the economic consequences of a 1959 1960 malaria eradication campaign in southwestern uganda the effort constitutes a rare large scale and well documented attempt to eliminate malaria in sub saharan africa and produced an immediate disease reduction we use this quasi experimental health shock to identify long term changes in educational and economic outcomes comparing the treatment district to a similar synthetic control we find malaria eradication raised educational attainment by about a half year for both males and females increased primary school completion among females and generated an almost 40 rise in the likelihood of male wage employment

inflation unemployment and public opinion polls it is well known that public opinion polls report that the public regards inflation as a more serious problem than unemployment in this paper we examine public opinion surveys with the aim of discovering what if anything the poll results mean we describe in some detail the questions about inflation and unemployment asked in the surveys and analyze the determinants in both cross section and time series of answers to those questions the typical opinion poll question about inflation and unemployment is which of the two problems inflation or unemployment do you think will cause the more serious economic hardship for people during the next year or so 1 section 1 discusses the possible issues to which opinion poll questions about inflation and unemployment might be relevant section 2 tabulates a variety of questions that have been asked along with the responses and examines the views expressed and their consistency both internal and across different polls section 3 presents a regression analysis of the cross sectional determinants of responses to the michigan poll question cited above while section 4 studies determinants of changes over time

convergence of inflationary shocks evidence from the caribbean in this paper we aim to shed some light on the inflation dynamics in the caribbean we analyse the inflation rates for twelve countries using various time series methods the results show that the inflation rates are mean reverting processes and that there is evidence of a convergence club in inflation rates within the area which contradicts previous studies our contribution implies a high degree of similarity in the dynamics of our target countries inflation rates

capacity choice under uncertainty in a duopoly with endogenous exit abstract applying the real options framework this article investigates the investment decision of the entrant given that an incumbent is already active both firms have an option to exit this market if the demand level falls too low the combination of three decision components capacity choice entry and exit timing results into multiple trigger strategies for the entrant in particular in the presence of a large incumbent it can either choose to coexist with its rival in a duopoly or eventually monopolize the market by installing a sufficiently large capacity the former scenario is realized when the market is large while the latter occurs when the market is small when the market is of intermediate size a hysteresis region emerges where the entrant does not take any actions and prefers to postpone investment

what can new survey data tell us about recent changes in distribution and poverty it has been claimed that in recent times the poor have lost ground both relatively and absolutely even when average levels of living have risen this article tests that claim using household surveys for 67 developing and transitional economies over 1981 94 it finds that changes in inequality and polarization were uncorrelated with changes in average living standards distribution improved as often as it worsened in growing economies and negative growth was often more detrimental to distribution than positive growth overall there was a small decrease in absolute poverty although with diverse experiences across regions and countries almost always poverty fell with growth in average living standards and rose with contraction

choosing among alternative discrete investment projects under uncertainty abstract irreversible choice among mutually exclusive projects under output price uncertainty is considered increasing returns are shown to make it optimal to wait for the largest project greater uncertainty of the price process makes it optimal to wait for a larger project

welfare consequences of gradual disinflation in emerging economies emerging economies display considerable inequality in monetary asset holdings rendering the recent disinflation nontrivial using a small open economy model with uninsurable idiosyncratic risk this paper shows that a gradual decline of 12 in the quarterly inflation rate leads to an aggregate welfare gain of 0 40 in consumption equivalent terms the poor gain less than the economy on aggregate despite holding a more inflation prone financial portfolio this is because unequal cash holdings make inflation tax payments of the poor much smaller than those of the rich when inflation tax revenues finance redistributive transfers that provide insurance cross sectional gains become even more dispersed

population size and civil conflict risk is there a causal link does an expansion of the population size expose nation states to a higher risk of suffering from civil conflict obtaining empirical evidence for a causal relationship is difficult due to reverse effects and omitted variable bias this article addresses causality issues by using randomly occurring drought as an instrumental variable to generate exogenous variation in population size for a panel of 37 sub saharan countries over the period 1981 2004 instrumental variable estimates yield that a 5 increase in population size raises the risk of civil conflict by around six percentage points

dynamics and stability of constitutions coalitions and clubs a central feature of dynamic collective decision making is that the rules that govern the procedures for future decision making and the distribution of political power across players are determined by current decisions for example current constitutional change must take into account how the new constitution may pave the way for further changes in laws and regulations we develop a general framework for the analysis of this class of dynamic problems under relatively natural acyclicity assumptions we provide a complete characterization of dynamically stable states as functions of the initial state and determine conditions for their uniqueness we show how this framework can be applied in political economy coalition formation and the analysis of the dynamics of clubs the explicit characterization we provide highlights two intuitive features of dynamic collective decision making 1 a social arrangement is made stable by the instability of alternative arrangements that are preferred by sufficiently many members of the society 2 efficiency enhancing changes are often resisted because of further social changes that they will engender

time to build option value and investment decisions abstract investment decisions and outlays are often made sequentially for example the rate at which construction proceeds is usually flexible and can be adjusted with the arrival of new information traditional discounted cash flow methods which treat the pattern of investment as fixed ignore this flexibility and understate the value of the project this paper uses contingent claims analysis to derive optimal decision rules and to value such investments we determine the effects of time to build opportunity cost and uncertainty on the investment decision for reasonable parameter values we show how a simple npv rule can lead to gross errors

a short note on updating the grilli and yang commodity price index the grilli and yang commodity price index is one of the most widely used commodity price series in the applied economics literature this note provides some practical advice on updating this data series by listing the base period index values identifying relevant data sources and describing a method for computing subindex weights in 1988 enzo grilli and maw cheng yang published their seminal article on the long run development of an index of 24 primary commodity prices gycpi deflated by an index of manufactured goods unit values the sample of average annual primary commodity prices covers about 54 percent of the primary commodity trade in the index reference period 1977 79 the deflators considered for manufacturing prices were the u s manufacturing price index usmpi and the manufacturing unit value index muv 1widely used and discussed the grilli and yang data set has been extended by a number of researchers the data have been employed in a variety of contexts in later studies thus the gycpi data continue to enjoy wide popularity in their own right and as a benchmark for new approaches to empirical studies

the long run effects of oil wealth on development evidence from petroleum geology we estimate the long run effects of oil wealth on development by exploiting spatial variation in sedimentary basins areas where petroleum can potentially form instrumental variables estimates indicate that oil production impedes democracy and fiscal capacity development increases corruption and raises gdp per capita without significantly harming the non resource sectors of the economy we find no evidence that oil production increases internal armed conflict coup attempts or political purges in several specifications failure to account for endogeneity leads to substantial underestimation of the adverse effects of oil suggesting that countries with higher quality political institutions and greater fiscal capacity disproportionately select into oil production
