This paper characterizes the short- and long-run Cournot equilibrium with heterogeneous firms and stochastic technological change. In our model, firms have different technologies with heterogeneous fixed and variable costs and various degrees of markups. In a framework with homogeneous firms,...

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...

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...

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...

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...

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...

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...

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...

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...

We revisit the size-volatility relationship in firm growth using administrative data on French manufacturing firms. Departing from the log-log linear decay commonly reported by other studies, we find a two-regime pattern: volatility declines steeply with size for small firms, but flattens for...

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...

This study aims to develop an original VcC scale in manufacturer-supplier relationships in industrial markets. Qualitative and quantitative methods were used in the study. The researchers first reviewed the scale development processes in the literature, and they utilized a five-stage scale...

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,...
