This paper clarifies one of the puzzling results of the economic growth literature: the impact of military expenditure is frequently found to be non-significant or negative, yet most countries spend a large fraction of their GDP on defense and the military. We start by empirical evaluation of...

We present a dynamic two-country model in which military spending, geopolitical risk, and government bond prices are jointly determined. The model is consistent with three empirical facts: hegemons have a funding advantage, this advantage rises with geopolitical tensions, and war losers suffer...

We study the role of war bonds and inflation in the presidential elections of the 1950s. During World War II, the federal government conducted aggressive campaigns to convince Americans to invest their savings in wartime savings bonds. Although the bonds were nonnegotiable and protected from...

We construct a dynamic general equilibrium model of foreign direct investment (FDI) and foreign technology adoption, incorporating adoption barriers, international technology spillover, and relative price advantages. A higher FDI conversion efficacy, a lower adoption barrier, or a stronger...

This paper studies China's four-fold increase in per capita GDP relative to the U.S. between 1995 and 2019. First, we argue that China's growth pattern is very similar to that of several other East Asia economies that initially grew very quickly. Second, we show that a minimalist...

Evidence suggests that the prehistoric Out of Africa Migration has impacted the degree of intra-population genetic and phenotypic diversity across the globe. This paper provides the first evidence that this migration has shaped cultural diversity. Leveraging a folklore catalogue of 958 oral...

We study the effects of monetary-policy-induced changes in Tobin's q on corporate investment and capital structure. We develop a theory of the mechanism, provide empirical evidence, evaluate the ability of the quantitative theory to match the evidence, and quantify the relevance for monetary...

This essay discusses the reasons for and implications of the decline in real interest rates around the world over the past several decades. It suggests that the decline in interest rates is largely explicable from trends in saving, growth, and markups. In this environment, greater government...

We propose a model that starts from the premise that intangible capital needs to be stored on some medium --- software, patents, essential employees --- before it can be utilized in production. Storage implies that intangible capital may be partially non-rival within the firm, leading to scale...

In the US and many other OECD countries, expenditures for defense-related R&D represent a key policy channel through which governments shape innovation, and dwarf all other public subsidies for innovation. We examine the impact of government funding for R&D - and defense-related R&D in...
