Cascading Innovation

Abstract

US government spending since World War II has been characterized by large investments in defense-related high-tech goods and services and R&D. In turn, this means that the Department of Defense (DoD) has had a large role in funding corporate innovation in the US. This paper (i) quantifies the impact of military procurement spending on corporate innovation by publicly listed firms and (ii) shows that DoD impact on innovation was not limited to the winners of defense contracts but instead cascaded through the supply chain of DoD contractors via indirect market size effects, working through firm-to-firm input linkages. We use a database of detailed, historical procurement contracts for all Department of Defense (DoD) prime contracts since 1966. Product-level spending shifts are used as a source of exogenous variation in firm-level procurement receipts. We combine this data with information on the supply chain linkages of publicly listed firms. Our estimates indicate that defense procurement has a positive direct impact on patenting and R&D investment, with an elasticity of approximately 0.07 across both measures of innovation for DoD contractors. Further, our estimates imply that the derived demand for inputs following the award of a DoD contract constitutes a large indirect market size effect for the suppliers of DoD contractors. These indirect market size effects in turn induce innovation cascades working up the supply chain. We find that the elasticity of innovation outcomes to indirect DoD market size shocks is about half of that estimated for direct contractors but affects a much larger number of firms, increasing the effect of defense spending on aggregate innovation by at least 20%.

Abstract

Over the past decade the United States has invested substantial resources in protecting its troops against improvised explosive devices (IEDs). Using newly declassified military records on individual IED explosions in Afghanistan from 2006-2014, we show that detonation and casualty rates did not decline during this period. Consistent with historical evidence from other substate conflicts, qualitative evidence from the Afghan conflict suggests that insurgents adapted quickly to neutralize military investments.

Abstract

One-fifth of the world's population lives in countries affected by fragility, violence and conflict, impeding long-term economic growth. However, little is known about how firms respond to local changes in security, partly because of the difficulty of measuring firm activity in these settings. This paper makes two contributions. First, we develop a method for observing private sector activity using mobile phone metadata, and validate this measure with administrative and survey-based data on over 2,300 firms in Afghanistan. Second, we use this new measure of firm activity to examine how local insecurity affects firm activity. We first illustrate this method using an empirical case study of the 2015 Taliban attack on Kunduz, Afghanistan's fifth largest city. We then generalize this approach by studying how nationwide location decisions of the Afghan private sector respond to over 100 large terrorist attacks occurring over the course of four years. We find that firms reduce presence in districts following major increases in violence; that these effects persist for up to six months; and that larger firms are more responsive to violence. We discuss potential mechanisms, firms' strategic adaptations, and implications for policymakers.

The Sword and the Shield: The Economics of Targeted Sanctions

Abstract

While broad economic sanctions have long been used as instruments of foreign policy, targeted sanctions focusing on specific individuals, entities, and transactions are relatively new and less understood. We present a model of firm performance under sanctions where the target government may be incentivized to “shield” some firms from the full brunt of sanctions. Then, using detailed firm and individual-level data, this paper empirically estimates the impact of targeted sanctions, focusing on sanctions deployed by the United States and the European Union against primarily Russian targets after the crisis in Ukraine in 2014 as a natural experiment. We find, on average, a sanctioned or associated company loses about one-quarter of its operating revenue, over one-half of its asset value, and about one-third of its employees relative to their non-sanctioned peers, suggesting targeted sanctions are quite “smart” in the sense of hitting the intended targets with relatively minimal collateral damage. We also find some evidence of spillover impact onto technically non-sanctioned targets. Finally, we find that “strategic” firms selling high-priority goods to the regime systemically outperform non-strategic firms under sanctions, consistent with our shielding hypothesis and demonstrating the policy tradeoff between the tactical and the strategic impact of targeted sanctions.
