Optimal fiscal policy under monopolistic competition with firm heterogeneity

Government spending is a policy instrument used to sustain economic development and improve social welfare. Empirical observations, however, reveal a significant decrease in the government spending to GDP ratio for the United States. In addition, the United States has been observed to exhibit a rise in firm heterogeneity in productivity in recent decades. This paper shows that the optimal size of government expenditure will decrease as firm heterogeneity increases. We thus indicate that the rise in firm heterogeneity in productivity may serve as a plausible vehicle to explain the decline in the share of government spending in GDP for the United States.     

Intra‐industry bankruptcy contagion: Evidence from the pricing of industry recovery rates

How does bankruptcy contagion propagate among industry peers? We study the debt recovery channel of industry contagion by examining whether the cost of a company's debt is affected by the observed recovery rates of its bankrupt industry peers. Our results show that lower industry recovery rates are associated with higher loan spreads, but only when the contracts were originated during industry bankruptcy waves. Consistent with the debt recovery channel of industry contagion, we find that the negative effects of industry recovery rates are significantly stronger under situations where the effect is expected to be more salient.

Tax policy implications for a two‐engine growing economy

In an endogenous growth model with two engines of R&D and capital, we investigate the environment of “inclusive growth” for tax reallocations (tax increases or tax credits) to gain broader benefits in terms of promoting the overall GDP growth without an increase in income inequality. Our results show that a tax increase in the capital‐good sector can result in inclusive growth, boosting overall growth and reducing income inequality, provided that the status quo tax rate is not too high. Surprisingly, tax credits are not able to achieve such inclusive growth. While the GDP growth rises, a tax credit in the R&D sector not only increases income inequality but also decreases the aggregate employment, if the labor mobility cost between the final‐good and R&D/capital‐good sectors is relatively low. This provides a caution to policymakers given the fact that research tax credits have served as a common incentive to strengthen the R&D environment.

Modeling undecided voters to forecast elections: From bandwagon behavior and the spiral of silence perspective

Forecasting election results has been a highly attractive activity among political and social scientists. Different forecasting methods have been proposed, but those based on public opinion polls are the most common. However, there are challenges to using opinion polls, especially because they neglect undecided voters. Due to the significant number of undecided participants and their impact on voting outcomes, we analyze the potential behavior of undecided voters by considering opinion polls and sentiment based on voter expectation from the perspective of the bandwagon effect and the spiral of silence. We establish a hierarchical Bayesian forecasting model to predict voting results, and apply it to the 2016 United States presidential election and the 2016 Brexit referendum. The results of our model suggest that voting outcomes are more predictable when fully utilizing the impact of undecided voters. The results indicate that integrating aggregated polls into the hierarchical Bayesian framework is a strong predictor for forecasting outcomes, and they provide evidence for the influence of sentiment based on voter expectation in forecasting election results.
