主讲人简介：
Shengyu Li obtained his PhD in Economics at The Pennsylvania State University in 2014. Before he joined in UNSW in 2018, he was a Lecturer in Economics in University of Durham, UK. Shengyu’s research interests lie in the intersection of Industrial Organization and International Trade, with a special focus on firm heterogeneity in productivity and input prices and their implications in trade participation, resource allocation and industry dynamics. His research agenda involves estimation of firm decisions using static or dynamic structural models with micro data. His work published in RAND Journal of Economics, Economic Journal, Journal of International Economics, International Economic Review, European Economic Review, International Journal of Industrial Organization.
摘要：
This paper examines the impact of China's expressway expansion between 1998 and 2007 on market integration and firm performance within the manufacturing sector. The rapid expansion of the transportation network significantly enhanced market connectivity, improving firms' access to both input and output markets and intensifying competition. We explore how individual firms are influenced by these changes in terms of productivity, intermediate input prices, and market power by developing a new approach to estimate these measures at the firm level. Our findings reveal that the expansion of the transportation network significantly improved firm centrality, leading to enhanced market access and increased competition. Improved upstream market access reduced input prices and raised markups, while better downstream access boosted productivity. Although increased competition exerted countervailing pressures, the effects of market access dominated. In addition, lower-performing firms, particularly those with lower productivity, higher input prices, and lower markups, benefited more from the network improvement, and consequently leads to regional convergence.

Tony received his Ph.D. in Finance in 2001 from UTS and Ph.D. in Applied Mathematics in 1995 from Flinders University in Australia, the two fundamental disciplines underpinning his teaching and research areas. His teaching included asset pricing, portfolio theory, investment, international finance, and derivatives.
摘要：
We develop a closed-form approach to examine the joint effect of “keep-ing up with the Joneses” (KUJ) preferences and time-varying sentiment of heteroge- neous beliefs on equilibrium asset price dynamics in a two-agent economy. We show that, due to KUJ, sentiment continues to have a significant effect on equilibrium as- set price, though the sentiment-driven agent does not survive in the long run. When agents are pessimism on average, the model is able to generate countercyclical equity premiums, procyclical and concave price-dividend ratios, excess and countercyclical stock volatility similar to those observed in the U.S. equity market. In particular, an average of 0.7% (p.a.) underestimation of the expected GDP growth based on the Survey of Professional Forecasts can explain about half of market equity premium. Moreover, the term structure of real interest rates is upward (downward) sloping when the short rate is relatively low (high).

摘要：
Employing a spatial equilibrium model and exploiting staggered solar farm installations across Chinese counties, this study reveals that solar energy development reduces local GDP per capita by an average of 2.7%. This negative effect, primarily from competition for high-value land, is more pronounced in counties with high land opportunity costs. We observe a 2% increase in the local population despite lower wages and higher housing costs, implying improvements in local amenities. Our findings emphasize the importance of incorporating land use dynamics in solar farm siting decisions to optimize economic and welfare outcomes.
