We consider the problem of testing for a structural break in the spatial lag parameter in a panel model (spatial autoregressive). We propose a likelihood ratio test of the null hypothesis of no break against the alternative hypothesis of a single break. The limiting distribution of the test is...

Between 1997 and 2014, US corn, soybean and cotton production almost fully converted to genetically modified crops. Starting around 2007, improved tight oil and shale gas technologies turned the declining US fossil fuel production into a booming industry. We study the effects of these two...

As with the market for goods and services, democratic competition involves political parties offering their services (policy programs) to citizen-consumers who vote for their preferred partisan supplier. Little is known about the partial effect of a shift in parties' seat shares for given voter...

To explore the propagation of undesirable policies in a form of populist extremism, we construct a social learning model featuring agency problems. Politicians in different countries sequentially implement a policy. Voters learn the incumbent politician's type and the desirable policy by...

The 1974 Budget Act marked a turning point in U.S. budgeting history. With the Act, Congress decisively asserted its fiscal power, becoming more independent from the President in developing the budget and appropriating funds. Lawmakers at the time believed that the status quo, wherein Congress...

An in-depth econometric analysis of US state-level data on an annual frequency, from 1976 to 2008, sheds new light on a plausible causal link between infrastructure investments, namely public spending on highways, and income inequality. This causal relationship is drawn out by using the number...

Rationale: Since 1998, funding for state tobacco control programs in the U.S. increased marketedly, including several states that focused on preventing youth smoking. In addition, cigarette prices have increased considerably over this same timeframe. There has been considerable debate in the...

The budget forms the legal basis of government spending. If a budget is not in place at the beginning of the fiscal year, planning as well as current spending are jeopardized and government shutdown may result. This paper develops a continuous-time war-of-attrition model of budgeting in a...

Economists recommend Pigouvian taxes as the most efficient way to fight climate change. Yet, carbon taxes are difficult to implement politically. To understand why, we study Washington State's two failed carbon tax referendums from 2016 and 2018—the first such votes in the United States. We...

In this chapter, we assess recent contributions of computational models to the study of politics. We focus primarily on agent-based models developed by economists and political scientists. These models address collective action problems, questions related to institutional design and performance,...
