Party polarization, political alignment, and federal grant spending at the state level

Research on the distribution of federal expenditures has provided mixed evidence showing that states with more legislators who belong to the president’s party and states with more legislators in the chamber majority tend to receive a larger allocation of federal funds. We add to this research by considering how political polarization and political alignment impact these presidential and congressional determinants of how the domestic US budget is distributed to the states. Our results show that states with a larger percentage of senators in the majority can secure a larger share of federal grant expenditures per capita when political polarization is relatively low

A Very Low-Carbohydrate Diet Improves Symptoms and Quality of Life in Diarrhea-Predominant Irritable Bowel Syndrome

Patients with diarrhea-predominant IBS (IBS-D) anecdotally report symptom improvement after initiating a very low-carbohydrate diet (VLCD). This is the first study to prospectively evaluate a VLCD in IBS-D

Finally, Nebraska: A Synthetic Control Analysis of Legislative Structure

I estimate the impact of Nebraska’s 1937 switch from a bicameral to a unicameral legislature on state-level government expenditures. Using the synthetic control method I create a counterfactual Nebraska from a weighted-average of other potential control states and compare spending in this “synthetic Nebraska” to spending in the real Nebraska. Relative to the synthetic control, Nebraska experiences a sharp decrease in expenditures per capita immediately following the switch to a unicameral legislature, however, the difference appears to diminish over time. Placebo tests show that if the change in Nebraska’s legislative structure were randomly assigned amongst the sample of states, and legislative structure had no real impact on spending, the likelihood of obtaining a treatment effect estimate as large as Nebraska’s would be 0.0213. While the initial drop in expenditures per capita lends support to the theory that bicameralism, by requiring more veto players, is associated with higher levels of government spending, the fact that the difference between Nebraska and synthetic Nebraska diminishes suggests that legislators are able to circumvent this constraint

Corporate decision making in the presence of political uncertainty: The case of corporate cash holdings

Using a quarterly panel of U.S. corporations over the period 1985 – 2014 we show that corporate managers respond to political uncertainty and economic policy uncertainty shocks in different ways. We proxy for political uncertainty using the Partisan Conflict Index and employ a prevalent empirical macroeconomic methodology to construct structural shocks that are orthogonal to shocks captured by the Economic Policy Uncertainty Index. Following a political uncertainty shock, corporations increase cash but do not adjust investment. Alternatively, following an economic policy uncertainty shock, firms appear to draw on cash and reduce capital spending to increase R&D spending

Partisan conflict, policy uncertainty and aggregate corporate cash holdings

This paper distinguishes political uncertainty from policy uncertainty shocks and uncovers new empirical facts about how each impacts the aggregate cash holdings of US firms. Our baseline structural vector autoregression model shows that an exogenous one standard deviation shock to political and economic policy uncertainty is followed by 1 and 1.8% increase in aggregate corporate cash-to-total assets after five and eight quarters, respectively. The baseline result also shows that policy uncertainty shocks tend to raise financial market volatility while political uncertainty shocks tend to lower financial market volatility. Moreover, we find evidence that political uncertainty exerts asymmetric effects on aggregate corporate cash holdings, with a shock tending to raise cash holdings under normal financial conditions and lower cash holdings under tight financial conditions. Our main results are robust against a wide range of shock identification schemes as well as against parametric and non-parametric model estimations
