Perez-Sebastian, F. ; Raveh, O. ; van der Ploeg, F. Oil discoveries and protectionism: Role of news effects. Journal of Environmental Economics and Management 2021, 107, 102425. Publisher's VersionAbstract
Can oil discovery shocks affect the demand for protectionism? An intertemporal model of Dutch disease indicates that if the tradable sector is politically dominant then an oil discovery can induce protectionism. If the economy is also credit constrained, this effect is intensified upon discovery, but partially reversed when oil revenues start to flow. We test these predictions using 16.2 million, HS-6 level, bilateral tariff rates that cover 5718 products in 155 countries over the period 1988–2012, and data on worldwide discoveries of giant oil and gas fields. Our identification strategy rests on the exogeneity of the timing of discoveries. Our empirical results indicate that an oil discovery increases tariffs during pre-production years and decreases tariffs in the years to follow yet to a lesser extent, most notably in capital scarce economies with a relatively dominant tradable sector. Our baseline estimates indicate that a giant oil field discovery induces a rise of approximately 13% in the average tariff over the course of 10 years; this increase is approximately 2.5 times larger during the pre-production period when the oil discovery represents a pure news shock.
Raveh, O. ; Tsur, Y. Reelection, growth and public debt. 2020, 63, 101889. Publisher's VersionAbstract
In this work we examine how economic growth affects public debt when interacted with reelection prospects. Reelection considerations shorten political time horizons and give rise to political myopia that exacerbates debt accumulation. That laxer institutional reelection restrictions (e.g., no term limits) mitigate this effect due to electoral accountability is well known. Incorporating growth, we find that this mitigation can be reversed because less myopic, and more accountable, incumbents put more emphasis on smoothing the effects of growth across generations. We test these predictions using an annual-based panel of U.S. states over the period 1963–2010. Our identification strategy rests on constitutionally-entrenched differences in gubernatorial term limits that provide plausibly exogenous variation in reelection prospects, and aggregate national TFP shocks that are exogenous to individual states. Our estimates indicate that when reelection is possible a one standard deviation positive income shock induces, within the same year, a relative increase of approximately $40 in real per capita public debt.
Raveh, O. Monetary Policy, Natural Resources, and Federal Redistribution. Environmental and Resource Economics 2020, 75, 585-613. Publisher's VersionAbstract
Can monetary policy shocks induce redistribution across natural resource rich and poor states within a federation? We conjecture that resource-rich states are capital intensive, hence their investment is more responsive to changes in monetary policy. Consequently, contractionary monetary policy shocks (e.g., increases in the interest rate) may induce redistribution from resource-poor states to resource-rich ones, via an equalizing federal transfer scheme, because investment is reduced more strongly in the latter. We test these hypotheses using a panel of U.S. states covering several decades, and find that: (1) resource-rich states are significantly and persistently more capital intensive; (2) contractionary monetary policy shocks induce a relative drop (increase) in investment (federal transfers) in resource-rich states, over the course of four years; (3) these patterns are driven by resource-induced differences in the capital share in the economy. We estimate that a one standard deviation contractionary monetary shock induces, within the first year, federal redistribution of approximately $$\$2.5$$$2.5 billion from the resource-poor to the resource-rich states, representing about $$11\%$$11% of the total average annual federal transfers received by the latter states.
Raveh, O. ; Tsur, Y. Resource windfalls and public debt: A political economy perspective  . European Economic Review 2020, 123, 103371. Publisher's VersionAbstract
Can natural resource windfalls increase public debt in democracies? Adopting a political economy perspective, we show that the answer is in the affirmative. Resource windfalls increase both the government’s income and wealth. The former mitigates the need to borrow, whereas the latter encourages further borrowing (as it improves its terms), implying an ambiguous pure effect of resource windfalls on debt. Re-election considerations shorten political time horizons and give rise to political myopia. We show that higher political myopia, induced by more stringent (institutional) re-election restrictions, magnifies the wealth effect, turning positive the effect of resource windfalls on debt. We test the model’s predictions using a panel of U.S. states over the period 1963-2007. Our identification strategy rests on constitutionally-entrenched differences in gubernatorial term limits that provide plausibly exogenous variation in re-election prospects, and geographically-based cross-state differences in natural endowments. Our baseline estimates indicate that a resource windfall of $1 induces an increase of approximately ¢20 in the public debt of states with more stringent re-election restrictions.
Perez-Sebastian, F. ; Raveh, O. Federal tax policies, congressional voting and natural resources. Canadian Journal of Economic 2019, 52, 1112-1164. Publisher's VersionAbstract
Abstract Can abundance of natural resources affect legislators' voting behaviour over federal tax policies? We construct a political economy model of a federalized economy with district heterogeneity in natural resource abundance. The model shows that representatives of natural resource-rich districts are more (less) willing to vote in favour of federal tax increases (decreases). This occurs because resource-rich districts are less responsive to federal tax changes due to the immobile nature of their natural resources. We test the model's predictions using data on roll-call votes in the US House of Representatives over the major federal tax bills initiated during the period of 1945–2003, in conjunction with the presence of active giant oil fields in US congressional districts. Our identification strategy rests on plausibly exogenous giant oil field discoveries and exploitation and narrative-based aggregate federal tax shocks that are exogenous to individual congressional districts and legislators. We find that: (i) resource-rich congressional districts are less responsive to changes in federal taxes and (ii) representatives of resource-rich congressional districts are more (less) supportive of federal tax increases (decreases), controlling for legislator, congressional district and state indicators. Our results indicate that resource richness is approximately half as dominant as the main determinant, namely party affiliation, in driving legislators' voting behaviour over federal tax policies.
Perez-Sebastian, F. ; Raveh, O. ; Reingewertz, Y. Heterogeneous vertical tax externalities and macroeconomic effects of federal tax changes: The role of fiscal advantage. Journal of Urban Economics 2019, 112, 85 - 110. Publisher's VersionAbstract
How do state tax rates respond to federal tax shocks? This paper presents a novel mechanism of heterogeneous vertical tax externalities across state-levels of fiscal advantage, showing that tax increases can be expansionary – even without their reinvestment. States rich in natural resources have a fiscal advantage in the inter-state competition over production factors which allows them to respond better to increases in federal taxes and, consequently, attract capital from other parts of the nation. We add heterogeneity in fiscal advantage levels to an otherwise standard model of vertical tax externalities and horizontal tax competition. The model shows that, irrespective of federal redistribution, the contractionary effect of a federal tax increase can be overturned in fiscally advantaged states, through an increase in their tax base. Using the case of the U.S., and narrative-based measures of federal tax shocks a-la Romer and Romer (2010), we provide empirical evidence for the various aspects of this mechanism. Specifically, our baseline estimates indicate that, controlling for federal transfers, a 1% increase in the GDP share of capital-related federal taxes at the beginning of a year increases the growth rate of the per capita tax base by approximately 0.7% in high fiscal advantage states at the end of it.
Perez-Sebastian, F. ; Raveh, O. What drives vertical fiscal interactions? Evidence from the 1980 Crude Oil Windfall Act. Regional Science and Urban Economics 2018, 73, 251-268.Abstract
In economies with multi-level governments, why would a change in the fiscal rule of a government in one level lead to a fiscal response by a government in a different level? The literature focused primarily on the standard common-pool problem, while giving little attention to the potential role of complementarity or substitutability (CS) between the public goods supplied by the two governments. This paper fills this gap by focusing on the latter channel. First, we illustrate its potential key role in determining the sign of the vertical reaction through a generic model of vertical fiscal interactions. Second, we propose a novel strategy for identifying it, by considering an empirical design that confines the common-pool channel to specific locations. We implement this design through a quasi-natural experiment: the 1980 U.S. Crude Oil Windfall Act, which increased federal tax collections from sale of crude oil, thereby affecting the tax base of oil rich states specifically. This latter feature enables attributing the vertical fiscal reactions of the remaining states to the CS channel. Following this strategy, via a difference-in-differences approach, we decompose the sources of the vertical fiscal reactions arising from this federal tax change and find that those attributed to the CS channel: (i) account for approximately 38% of the overall vertical fiscal response; (ii) point at complementarity between state and federal public goods, most notably in transportation and welfare expenditures; (iii) are manifested primarily via changes in states' sales and income taxation.

Raveh, O. ; Reshef, A. Capital imports composition, complementarities, and the skill premium in developing countries. Journal of Development Economics 2016, 118, 183 - 206. Publisher's VersionAbstract
We study how the composition of capital imports affects relative demand for skill and the skill premium in a sample of developing economies. Capital imports per se do not affect the skill premium; in contrast, their composition does. While imports of R&D-intensive capital equipment raise the skill premium, imports of less innovative equipment lower it. We estimate that R&D-intensive capital is complementary to skilled workers, whereas less innovative capital equipment is complementary to unskilled labor—which explains the composition effect. This mechanism has substantial explanatory power. Variation in tariffs, freight costs and overall barriers to trade, over time and across types of capital, favors imports of skill-complementary capital over other types. We calculate that reductions in barriers to trade increase inequality substantially in developing countries through the composition channel.
Perez-Sebastian, F. ; Raveh, O. Natural resources, decentralization, and risk sharing: Can resource booms unify nations?. Journal of Development Economics 2016, 121, 38 - 55. Publisher's VersionAbstract
Previous studies imply that a positive regional fiscal shock, such as a resource boom, strengthens the desire for separation. In this paper we present a new and opposite perspective. We construct a model of endogenous fiscal decentralization that builds on two key notions: a trade-off between risk sharing and heterogeneity, and a positive association between resource booms and risk. The model shows that a resource windfall causes the nation to centralize as a mechanism to either share risk and/or prevent local capture, depending on the relative bargaining power of the central and regional governments. We provide cross country empirical evidence for the main hypotheses, finding that resource booms: (i) decrease the level of fiscal decentralization with no U-shaped patterns, (ii) cause the former due to risk sharing incentives primarily when regional governments are relatively strong, and (iii) have no effect on political decentralization.
Perez-Sebastian, F. ; Raveh, O. The Natural Resource Curse and Fiscal Decentralization. American Journal of Agricultural Economicsajae 2015, 98, 212 - 230. Publisher's VersionAbstract
Natural resource abundance is a blessing for some countries, but a curse for others. We show that differences across countries in the degree of fiscal decentralization can contribute to this divergent outcome. Using a large panel of countries covering several decades and various fiscal decentralization and natural resource measures, we provide empirical support for the novel hypothesis. We also study a model that combines political and market mechanisms under a unified framework to illustrate how natural resource booms may create negative effects in fiscally decentralized nations.
