This paper analyzes how the U.S.-China trade war affected Korean industries and identifies the industry characteristics that determined which industries gained or lost. I show that heterogeneity in responses is closely linked to capital intensity and export intensity, highlighting the role of...

Government debt can potentially enhance high-quality economic development, yet its effects and risks diverge substantially under the interplay of scale economies and diseconomies. Against the backdrop of the 20th CPC Central Committee's Third Plenary Session, which emphasized coordinated...

We estimate measures of economies of scale and scope for a sample of 48 Canadian universities that produce multiple outputs. Estimates have not been previously attempted for Canadian universities to our knowledge. Declining financial support from provincial governments makes finding cost...

In recent decades, the German wine market has undergone significant structural changes due to intensifying competition and shifting consumption patterns. Increased imports and declining exports have pressured German wine estates to adapt for survival. The study explores these long-term trends...

This paper studies the impact of AI on productivity and inequality by focusing on the introduction of AlphaFold2. This AI algorithm can accurately predict protein structures, which were traditionally characterized by structural biologists through experiments. To capture the impact of AI on...

Transaction-level quantity discounts are a pervasive feature of US trade, shaping both price variation and tariff incidence. Using administrative microdata, we show that these discounts reflect transaction-level scale economies rather than market power. Accounting for these micro-level economies...

I examine whether trade can improve the impact of population growth on natural resources (NR) and welfare over time. Under autarky, population growth results in NR and welfare collapse over time, irrespective of the value of the returns to scale in the manufacturing sector, ϕ. Under trade, NR...

This paper develops a dynamic model in which the productivity of joint research governs strategic investment timing in innovation races. Departing from the standard assumption that discovery rates scale proportionally with the number of active firms, we allow research to exhibit decreasing or...

We seek to explain positive correlations between green investments and long-term financial holdings, the size of the economy and the variance in GDP. To this end, we develop a model for green investments that expands on a standard non-cooperative private provision of public goods game, with...

Bilateral trade shocks affect firms in third countries by redirecting demand and reallocating competition across markets, creating winners and losers. We propose a tractable trade model with heterogeneous firms to decompose firm-level export responses as a function of destination-specific...

This article tries to estimate the operating efficiency among 30 years (1989-2018) in the information technology (IT) industry, where technologies are everchanging. The balanced panel data model of Kneip et al. is extended to an unbalanced panel data model for more generic applications. The...

One of the key questions in the study of regulation is whether the costs of regulatory compliance fall homogeneously on all businesses or whether certain firms, for instance small ones, are especially penalized. We quantify firms' compliance costs in terms of their labor spending to adhere to...

The word "efficiency" has several technical meanings. Some of them are confused with productivity, with economies of scale and with optimization. There are also some lay meanings which are vague enough; they allude to effectiveness, to competence, to adequacy, to doing something well, and to...

The bio-based industry sector is a vital part of the bioeconomy. It can deliver sustainable alternatives to fossil-based products, fostering industrial competitiveness and sustainable economic growth for the EU. The EU's bio-based industry has strong fundamentals but faces challenges when it...

This paper investigates how Artificial Intelligence (AI) goes beyond traditional technological roles to drive transformation across industries, organisations, and society. By analysing 2188 academic papers from the arXiv platform (from 2018 until 2025), the study highlights the unexpectedly...

Economists routinely use survey measures of, for example, risk preferences, trust, political attitudes, or wellbeing. The literature generally treats numerical response categories as if they represent equal psychological intervals. We provide the first systematic test of this assumption,...

Bank market power has far-reaching effects as, among other things, it affects the price of credit. Even though it is well-known that banks are spatially interdependent due to rival banks having branches in the same geographical areas, the literature on bank market power overlooks this. To...
