New Demand Economics: Education, Demand Upgrading, and Structural Change

Education can change what households buy as well as what workers produce. We study this demand channel in a two-sector growth model. Education shifts spending toward an education-sensitive bundle, drawing labor into the sector that supplies it. Learning lowers its relative price. When substitution between the bundles is strong enough, the price decline raises its expenditure share and reinforces the initial shift. The balance between this feedback and technological catch-up determines the long-run allocation. Weak feedback gives a unique stable configuration. Strong feedback can sustain two stable configurations with different expenditure shares, so the long-run outcome depends on initial productivity. A sufficiently large, attainable increase in education removes the low-share configuration. This transition can occur through demand alone, without a direct productivity effect of education. Early consumption commitments can also change the economy's destination, even though their budget share eventually vanishes. The growth and welfare consequences depend on learning gained in the expanding sector and learning forgone in the other. We derive the net learning benefit that a planner would attach to reallocation.

When Trust Attracts Fraud: AI and Trust Arbitrage

Trust can attract fraud when it delays verification. We develop a two-market signaling model in which generative AI lowers fabrication, verification, and targeting costs. When fabrication becomes profitable before verification, claim credibility first falls and later recovers. Across markets, higher prior quality can delay verification, creating an interval in which only the lower-quality market checks. If targeting becomes profitable in this interval, deceptive sellers enter the higher-quality but less vigilant market, and their entry can initially reverse its reliability advantage. The inflow also triggers verification and deters further entry. We call this self-limiting mechanism trust arbitrage. In the age of generative AI, trust can thus create an endogenous but temporary protection gap that redirects deception across markets.

Cross-shareholding networks and stock price synchronicity: Evidence from China

This paper investigates the effect of cross-shareholding on stock price synchronicity, as a measure of price informativeness, of the listed firms in the Chinese stock market. We gauge firms' levels of cross-shareholdings in terms of centrality in the cross-shareholding network. It is confirmed that it is through a noise-reducing process that cross-shareholding promotes price synchronicity and reduces price delay. More importantly, this effect on price informativeness is pronounced for large firms and in the periods of market downturns. Overall, our analyses provide insights into the relation between the ownership structure and price informativeness.
