07/30:REGULATING EXTERNALITIES: WELFARE THEOREMS, CAP-AND-TRADE, AND PIGOUVIAN TAXES
地点：1F, Wanzhong Building, Langrun Garden, Peking University
演讲人：端木昊随

The general equilibrium framework introduced by Anderson and Duanmu (2025a) incorporates cap-and-trade and emission taxation, the two most widely used regulatory schemes to control greenhouse gas emissions, into the Arrow–Debreu model. This paper extends that model by allowing externalities affecting production technologies. We show that the first welfare theorem fails in the presence of interdependent production technologies. In contrast, we establish versions of the second welfare theorem for these two regulatory schemes. Specifically, we show that every Pareto optimum can be decentralized both as a cap-and-trade equilibrium with transfers and as an emission tax equilibrium with transfers. This provides a rigorous foundation for Pigouvian taxation in general equilibrium economies with multiple agents.

07/01:Digital Economy and the Global Financial System
地点：1F, Wanzhong Building, Langrun Garden, Peking University
演讲人：Vincenzo Quadrini

The growth of the Digital Economy could have important implications for international financial markets, including the centrality of traditional reserve assets such as the US dollar. On the one hand, the creation of digital assets, especially Stablecoins, could increase the demand for traditional reserve assets. On the other, digital assets could serve as a substitute for traditional reserve assets, reducing their global demand. We find that, in the long-run, the increase in the demand for reserve assets dominates the substitution of traditional reserve assets. This would lead to lower US interest rates and larger US foreign borrowing. We also find that the expansion of the Digital Economy would result in higher idiosyncratic consumption volatility in the US but lower volatility in the rest of the world.
