The Fifth Symposium (Winter Camp) on New Structural Economics Successfully Concluded

The Institute of New Structural Economics at Peking University (INSE) hosted the Fifth Symposium (Winter Camp) on New Structural Economics (NSE) from December 15 to 18, 2019 in Beijing. Inaugurated in 2015, the annual symposium demonstrates the theoretical framework, latest research and database construction outcome, and future research prospects of NSE. This 5th edition of the symposium brings together well-known economists and young researchers at home and abroad to discuss issues related to NSE to deepen NSE research.

Tariff barrage hits harder in Washington—Former World Bank economist: 'If the US wants to talk, our door is wide open'

Washington's so-called "reciprocal tariffs" are hurting the United States more than China, and if the US wants to talk, China is expected to be open only to negotiations based on equality and fairness, said a senior economist.

05/20:Digital Infrastructure, Green Transition? Evidence from Input-Output Networks
Venue：1F, Wanzhong Building, Langrun Garden, Peking University
Speaker：Stéphane Straub

This paper assesses to what extent digitalization of activities throughout the economy may make other sectors more efficient in terms of CO2 emissions. We address this question using inter-country input-output (IO) tables across 76 developed and emerging countries across 45 sectors between 1995-2020, matched with sector-level GHG emissions. We use IO tables from the OECD to document stylized facts on the size and centrality of the digital sector between 1995-2020 and exploit country-sector variation in the intensity of digital inputs used within downstream sectors to gauge impacts on total emissions, output and emissions per unit of output. Following logic of endogenous production networks, we further generate a shift-share instrument for input diffusion. We find limited evidence that adoption of digital inputs decreases emissions per unit of output in downstream sectors. We identify a small decrease in total sectors output as a result of increased digital intensity, but an average null effect on total emissions or emissions per unit of output. We do also show heterogeneity across countries and sectors. When instrumenting digitization, we find that output and total emissions increase, so do emissions per unit of output. The “digital enablement” effect cannot be assumed from movement towards greater digitization.

05/16:Income Distribution, Welfare, and the Patterns of Trade
Venue：1F, Wanzhong Building, Langrun Garden, Peking University
Speaker：Reto Foellmi

We develop a two-country model of international trade featuring non-homothetic prefer-ences and income inequality, generating a price schedule where cheap necessities coexist with expensive luxury goods. A central mechanism driving price differences is firm's ability to shift fixed costs between countries, shaping trade patterns and welfare. In a North-South setting, poor consumers in the rich country are most negatively affected by this fixed cost shifting, leading to a Manhattan effect. Following mean-preserving redistribution, import volumes rise in the unequal country, and fall in the more equal one.
