This study examines the long-term effects of higher national debt in South Korea on asset distribution. Using an overlapping generations general equilibrium model, we focus on two key channels: rising interest rates and falling wage rates, both driven by the crowding-out effect of capital....

This paper revisits paradigmatic differences in economics with a focus on input-output modeling. We show that such differences represent deep divides in economic theorizing and impact strongly on the magnitude and signs of expected effects. At the same time estimates from input-output models are...

Welfare economics relies on access to agents' utility functions: we revisit classical questions in welfare economics, assuming access to data on agents' past choices instead of their utilities. Our main result considers the existence of utilities that render a given allocation Pareto optimal. We...

We examine the welfare effects of removing explicit and implicit fossil fuel subsidies, the latter entailing Pigouvian pricing of local externalities from fossil energy consumption. We map a multi-region, multi-sector general equilibrium model to granular data on subsidies, local marginal...

This paper challenges the prevailing narrative that mathematical economics, particularly in the post-war era, neglected the study of social institutions. According to the common view, the concept of institutions was largely abandoned following the decline of institutionalism, only to be revived...

We show that in a canonical model with heterogeneous entrepreneurs, financial frictions, and an imperfectly elastic supply of capital, a fall in the interest rate has an ambiguous effect on aggregate economic activity. In partial equilibrium, a lower interest rate raises aggregate investment...

Heterogeneous beliefs among market participants can lead to questionable speculative trading that goes beyond any risk-sharing motives. We demonstrate that such unwarranted betting behavior in market equilibrium can be mitigated by introducing nonlinear pricing for ambiguous contracts, without...

We leverage decades of administrative data and quasi-experimental variation in the introduction of universal long-term care (LTC) insurance in Germany in 1995 to examine whether health insurance expansions can stimulate local economies. We find that the LTC insurance rollout led not only to...

Does it pay to invest in green companies? In countries where a market for carbon is functioning, such as those within the European Union, our findings suggest that it should be beneficial. Using a sample of green and brown European firms, we initially demonstrate that green companies have...

This paper characterizes equilibrium properties of a broad class of economic models that al-low multiple heterogeneous agents to interact in heterogeneous manners across several markets. Our key contribution is a new theorem providing sufficient conditions for uniqueness and stability of...

We investigate how the level of corporate leverage affects firms' investment response to monetary policy shocks. Based on novel aggregate time series estimates, leverage acts amplifying, whereas in the cross section of firms, higher leverage predicts a muted response to monetary policy. We use a...

After decades of globalization, many countries are now considering various measures to reduce their dependence on third countries and to incentivize domestic production. This paper analyzes a policy toolbox encompassing trade, industrial, and public policies and their effects on the EU and its...

Fabio Petri's Microeconomics for the Critical Mind (2021) is an impressive tour de force in the field of microeconomic theory. It manifests the author's command of cutting edge analytical tools, concepts, and theoretical approaches both in the mainstream and in the heterodox literature. The book...

This paper proposes to explain the productivity growth slowdown with the poaching of disruptive inventors by firms these inventors threaten with their research. I build an endogenous growth model with incremental and disruptive innovation and an inventor labor market where this defensive...

We estimate the macroeconomic effects of import tariffs and trade policy uncertainty in the United States, combining theory-consistent and narrative sign restrictions on Bayesian SVARs. We find mostly adverse consequences of protectionism. Tariff shocks are more important than trade policy...

This paper presents a macroeconomic evaluation of the impact of the Horizon 2020 funds, carried out using the spatial dynamic general equilibrium model RHOMOLO. The policy disbursement data used to feed the model relate to the actual use of the funds over the period 2014-2021, so this is...

Korea's National Pension Fund (NPF) is projected to be in deficit by the 2040s and exhausted by the 2050s. Increasing contribution rates may be unaffordable, prompting consideration of structural reforms, particularly shifting from a defined benefit (DB) to a defined contribution (DC) system....

This paper proposes a general equilibrium model with the entrepreneurial sector for the Russian economy. The novelty of the model lies in several points. First, the model is a small open economy. Second, it includes the entrepreneurial sector. Third, the model reflects the main features of the...

This paper investigates the conditions under which socially responsible investment (SRI) is neutral from the viewpoint of general equilibrium theory. Three conditions are jointly sufficient for neutrality of SRI. First, the financial market is complete and SRI does not compromise the spanning...

We present a new framework for estimating the long-run economic impacts of natural disasters. Our approach combines a disaster impact model with a general equilibrium model of the economy. We apply the methodology to study the effects of tropical cyclones in the United States, the Caribbean...
