This paper mainly studies two topics: linear complementarity problems for modeling electricity market equilibria and optimization under uncertainty. We consider both perfectly competitive and Nash-Cournot models of electricity markets and study their robustifications using strict robustness and...

The smartphone apps have revolutionized the markets of goods and services more than other recent technologies. Although they modified the market paradigm in sectors like accommodation, transport, or "gigs", the changes in the way the economics systems function are still widely neglected by the...

This study re-examines the impact of corruption on international trade accounting for both inter- and intra-national flows in line with the latest advances in the gravity equation literature. Using a wide sample of countries for the period 1995-2017, our results show that the non-inclusion of...

Economic disruptions generally create winners and losers. The compensation problem consists of designing a reform of the existing income tax system that offsets the welfare losses of the latter by redistributing the gains of the former. We derive a formula for the compensating tax reform and its...

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....

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...

The study of entrepreneurship often focuses on the activities of the entrepreneur. While entrepreneurship is undertaken by individuals, the degree to which individuals are entrepreneurial, and the directions in which their entrepreneurial actions take, are the result of the institutional...

We propose a novel approach to deal with the problem of indeterminacy in linear rational expectations models. The method consists of augmenting the original state space with a set of auxiliary exogenous equations to provide the adequate number of explosive roots in presence of indeterminacy. The...

We describe the procedure used to construct a set of interregional NUTS-2 European Union Social Accounting Matrices for the year 2017, using official Eurostat national and regional account data, and auxiliary data on business and interregional trade flows derived from transport survey data. This...
