In an infinite-horizon model with Marshallian time preferences, foreign aid, foreign borrowing, and domestic capital accumulation, this paper reexamines the effects of foreign aid on domestic capital accumulation and foreign borrowing. Comparative static analysis shows that a permanent increase...

This paper considers foreign asset holdings and macroeconomic policies in a finite-horizon model with real balances and foreign asset holdings in a small open economy. Both the long- and short-run effects of these macroeconomic policies on the economy are reexamined. The main results stand in...

Previous literature on the effectiveness of pollution charges in achieving energy conservation has yielded inconsistent conclusions. By employing a quasi-natural experiment based on China's Environmental Protection Tax Reform (EPT), we analyze this question. In 2018, China implements...
