Military expenditures significantly affect the relationship between the risk of civil conflict outbreak and natural resources. We show that a significant positive effect of natural resource rents on the risk of civil conflict outbreak is limited to countries with low military expenditures. In countries with high military expenditures, there is no s...

In many western democracies, political parties with extreme platforms challenge more moderate incumbents. This paper analyses the impact of economic growth on the support for extreme political platforms. We provide a theoretical argument in favor of growth effects (as opposed to level effects) on the support for extreme political parties and we emp...

This paper provides new insights on the link between structural change and the fertility transition. In the early 1890s agricultural production in the American South was severely impaired by the spread of an agricultural pest, the boll weevil. We use this plausibly exogenous variation in agricultural production to establish a causal link between ch...

Whereas existing literature has documented strong correlations between national incomes and measures of schooling attainment, causality has been hard to pin down. In this paper we explore from an empirical perspective whether income windfalls cause schooling. We do so by focusing on within-country variation and exploiting variation in the internati...

This paper revisits the effect of national income on distributional equality. Although the link between the two has featured prominently in the literature, a causal effect has been difficult to pin down due to the endogeneity of these variables. We use plausibly exogenous variations in the incomes of countries’ trading partners weighted by the leve...

We revisit the debate of whether government spending is procyclical in developing countries. Our main contribution is to argue that, beyond exogeneity of the income shock, an empirical analysis of government spending cyclicality must be carefully taylored to the shock's persistence. We first illustrate this point in a simple intertemporal model. We...

We examine the effects of variations in the international food prices on political institutions in low-income countries. Our empirical analysis exploits that the economic impact of changes in the international food prices differs across countries depending on whether countries are net food importers or exporters. We construct an international food...

We examine the effect of genetic diversity on economic development in the United States. Our estimation strategy exploits that immigrants from different countries of origin differed in their genetic diversity and that these immigrants settled in different regions. Based on a sample of over 2250 counties, we find that increases in genetic diversity...

Do populations grow as countries become richer? In this paper we estimate the effects on population growth of shocks to national income that are plausibly exogenous and unlikely to be driven by technological change. For a panel of over 139 countries spanning the period 1960-2007 we interact changes in international oil prices with countries’ averag...

This paper studies the effects of growth in countries’ national incomes on political risk. To address causality, we use the annual growth rate of the international oil price weighted with countries’ average oil net-export GDP shares as an instrument for national income growth. Our instrumental variables analysis yields two main results: (i) income...

We estimate local government spending multipliers using annual data for 47 Japanese prefectures during the 1990s. Our main findings are as follows: the average local government spending multiplier is positive and significantly different from zero but not larger than one; there are large and significant differences in the output effects of different...

We exploit the large inflow of immigrants to the US during the 1870–1920 period to examine the effects that within-county changes in the cultural composition of the US population had on output growth. We construct measures of fractionalization and polarization to distinguish between the different effects of cultural diversity. Our main finding is t...

This paper provides instrumental variables estimates of the response of aggregate private consumption to transitory output shocks in poor countries. To identify exogenous, unanticipated, idiosyncratic and transitory variations in national output we use year-to-year variations in rainfall as an instrumental variable in a panel of 39 sub-Saharan Afri...

This paper presents instrumental variables estimates of the effects of GDP per capita volatility on the size of government. We show that for a panel of 157 countries spanning more than half a century, rainfall volatility has a significant positive effect on GDP per capita volatility in countries with above median temperatures. In these countries ra...

Whereas existing literature has documented strong correlations between national incomes and measures of schooling attainment, causality has been hard to pin down. Much of empirical work had tended to interpret these correlations as implying an effect of human capital on national income, but recent calibrated models have argued that most of the link...

This paper shows that foreign aid has a significant positive average effect on real per capita gross domestic product (GDP) growth if, and only if, the quantitatively large negative reverse causal effect of per capita GDP growth on foreign aid is adjusted for in the growth regression. Instrumental variables estimates show that a 1 percentage point...

This paper provides instrumental variable estimates of the permanent income elasticity of government expenditures. It uses annual variation in the international oil price weighted with countries' average oil net-export GDP shares as a plausibly exogenous source of within-country variation in countries’ permanent income. The short-run estimates of t...

Structural VARs indicate that for many OECD countries labor force participation, employment, and the unemployment rate significantly increase following increases in government expenditures under a variety of specifications and identification schemes. Fiscal expansions also tend to increase real wages. Existing models have difficulties in generating...

To what extent has Sub-Saharan Africa's slow economic growth over the past five decades been due to price and trade policies that discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy induced distortions to relative agricultural prices to address this question econometrically...

This paper exploits the significant response of real GDP growth of Sub-Saharan African countries to exogenous international commodity price and rainfall shocks to construct instrumental variables estimates of the tax revenue elasticity IV estimates yield that a 1% increase in GDP increases tax revenues by up to 2.5%.

In this paper, we study the causal effect of income growth on institutional quality in the 1984-2007 cross country panel. To focus on exogenous income windfalls, we employ international oil price shocks as an instrument for income growth. While national incomes and measures of institutional quality are highly correlated, our analysis fails to ident...

In the 1990s the mainstream consensus was that trade causes growth. Subsequent research shed doubt on the consensus view, as evidence suggested that the identification of the effect of trade on growth was problematic in the existing literature. This paper contributes to this debate by focusing on growth in Sub-Saharan Africa. It estimates the effec...

This paper exploits the significant positive response of the share of agricultural value added and GDP per capita growth to variations in the international prices for agricultural commodities and rainfall to construct instrumental variables estimates of the causal effect that changes in the size of the agricultural sector and GDP per capita growth...

This research revisits the cyclicality of fiscal policies. To identify and estimate more precisely the magnitude of a causal effect of cyclical income on government spending, we employ annual rainfall data as an instrument for national income in the context of sub-Saharan countries. Our results confirm procyclical behavior of government spending an...

We estimate the income elasticity of government expenditures using variation in the international oil price as a plausibly exogenous source of within-country variation of countries' permanent income. Our short run elasticity estimates, between 0.25-0.50, are generally somewhat smaller than the previously obtained ones, and they, in particular, indi...

The hosting and bidding for the Olympic Games is a natural experiment to test for anticipation effects in macroeconomics. We examine these effects using panel data for 184 countries during the period 1950-2006. We find that hosting the Games generates positive investment, consumption, and output responses already before the hosting of the Games. We...

We use annual variation in rainfall to examine the effects that exogenous, transitory income shocks have on remittances in a panel of 42 Sub-Saharan African countries during the period 1960-2007. Our main finding is that these income shocks have a significant positive effect on remittances, but that the effect is significantly decreasing in the sha...

We show that democratic change may be triggered by transitory economic shocks. Our approach uses within-country variation in rainfall as a source of transitory shocks to sub-Saharan African economies. We find that negative rainfall shocks are followed by significant improvement in democratic institutions. This result is consistent with the economic...

Djankov and Reynal Querol (2010, RESTAT) show that the level of GDP per capita has no significant effects on the risk of civil war once country fixed effects are accounted for. Therefore, they argue that the relationship between income and civil war is spurious. This paper shows that when focus is on the change, rather than on the level, of GDP per...

We examine the effects that variations in the international food prices have on democracy and intra-state conflict using panel data for over 120 countries during the period 1970-2007. Our main finding is that in Low Income Countries increases in the international food prices lead to a significant deterioration of democratic institutions and a signi...

We examine the effect of oil price fluctuations on democratic institutions over the 1960-2007 period. We also exploit the very persistent response of income to oil price fluctuations to study the effect of persistent (oil price-driven) income shocks on democracy. Our results indicate that countries with greater net oil exports over GDP see improvem...

We examine the effects that variations in the international food prices have on democracy and intra-state conflict using panel data for over 120 countries during the period 1970-2007. Our main finding is that in Low Income Countries increases in the international food prices lead to a significant deterioration of democratic institutions and a signi...

We examine the effects that windfalls from international commodity price booms have on external debt in a panel of 93 countries during the period 1970–2007. Our main finding is that increases in the international prices of exported commodity goods lead to a significant reduction in the level of external debt in democracies but to no significant red...

A common finding in the empirical civil war literature is that population size and per capita income are highly significant predictors of civil war incidence and onset. This paper shows that the common finding of population size and per capita income having a significant average effect on civil war risk in a world sample breaks down once countryand...

To what extent has Sub-Saharan Africa's slow economic growth over the past five decades been due to price and trade policies that have discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy distortions to relative prices to address this question econometrically. We first test...

I argue that the commonly used nominal measure of natural resource dependence - the share of exports of primary products in GNP - understates in growth regressions the negative link between natural resource dependence and per capita GDP growth. I show that using a purchasing power parity adjusted measure yields an economically much larger negative...

This paper examines the effect that windfalls from international commodity price booms have on net foreign assets in a panel of 145 countries during the period 1970-2007. The main finding is that windfalls from international commodity price booms lead to a significant increase in net foreign assets, but only in countries that are homogeneous. In po...

We examine the effect that revenue windfalls from international commodity price booms have on sovereign bond spreads using panel data for 38 emerging market economies during the period 1997-2007. Our main finding is that commodity price booms lead to a significant reduction in the sovereign bond spread in democracies, but to a significant increase...

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 exo...

Para entender mejor los efectos de las condiciones económicas sobre las guerras civiles, examinamos si las guerras civiles en África Subsahariana han sido más probables después de caídas en los precios internacionales de los principales bienes de exportación. Nuestras estimaciones indican un efecto robusto de las caídas de precios internacionales s...

I use a panel of large European firms for the period 1999-2007 to study scale dependence in firm dynamics. I find that scale dependence is much more pronounced when focusing on within-firm rather than between-firm variation and that scale dependence is a decreasing function of financial development.

In many western democracies, political parties with extreme platforms challenge more moderate incumbents. This paper analyses the impact of economic growth on the support for extreme political platforms. We provide a theoretical argument in favor of growth effects (as opposed to level effects) on the support for extremist parties and we empirically...

How effective was public investment in stimulating the Japanese economy during the economic stagnation of the 1990s? Using a dataset of regional public investment spending, we find that investment multipliers were higher than for public consumption, although they were relatively low and declining over time. The paper also finds that the effectivene...

We examine the effects that international commodity price shocks have on external debt using panel data for a world sample of 93 countries spanning the period 1970-2007. Our main finding is that positive commodity price shocks lead to a significant reduction in the level of external debt in democracies, but to no significant reduction in the level...

We use a rich dataset of regional government expenditures for Japan during the 1990-2000 period to estimate from within-prefecture variation the fiscal multiplier of government investment and government consumption expenditures. Our main finding is a small but significantly positive multiplier on government investment. The multiplier on government...

We examine the effects of oil rents on corruption and state stability exploiting the exogenous within-country variation of a new measure of oil rents for a panel of 31 oil-exporting countries during the period 1992 to 2005. We find that an increase in oil rents significantly increases corruption, significantly deteriorates political rights while at...

Does economic growth affect the likelihood of civil war? Answering this question requires dealing with reverse causation. Our approach exploits that international commodity prices have a significant effect on the income growth of Sub-Saharan African countries. We show that lower income growth makes civil war more likely in non-democracies. This eff...

Capital market theory predicts that the wealth distribution of an economy affects real interest rates. This paper empirically analyzes this relationship for the US, the UK and Sweden. We obtain that measures of wealth inequality are positively linked to the real rate on government securities in all three countries. This result is consistent with pr...

Estimating the effect that foreign aid has on economic growth is complicated by the endogeneity of foreign aid to aid recipient countries' per capita GDP growth. To quantify the endogenous response of foreign aid to economic growth, I use rainfall as an instrumental variable to generate exogenous variation in per capita GDP of 47 LDC countries duri...
