A Hyper-Matheuristic Approach for Solving Mixed Integer Linear Optimization Models in the context of Data Envelopment Analysis

Abstract Mixed Integer Linear Programs (MILPs) are usually NP-hard mathematical programming problems, which present difficulties to obtain optimal solutions in a reasonable time for large-scale models. Nowadays, metaheuristics are one of the potential tools for solving this type of problems in any context. In this paper, we focus our attention on MILPs in the specific…

Develando los determinantes de la desigualdad del ingreso en Chile: Estudio empírico regional

Resumen El estudio busca responder cuáles son los determinantes de la desigualdad del ingreso en Chile, desde la perspectiva de sus regiones. El análisis empírico (1990-2016) demuestra que en Chile la relación entre el PIB per cápita y el Gini no tiene la tradicional forma de la U invertida de Kuznets, sino más bien, el…

La dinámica de la desigualdad en Chile: una mirada regional

Resumen El estudio retrata la dinámica de las desigualdades en Chile (1990-2016) desde la perspectiva de sus regiones. Se construye una amplia base de datos con distintas medidas de desigualdad del ingreso. Se devela gran heterogeneidad entre las regiones chilenas. Se observa que las regiones más desiguales, son igualmente aquellas con menor PIB per cápita…

Prevalence of the born-global phenomenon in different countries: an integrated perspective

Abstract Purpose: The main purpose of this study is to analyze how factors such as innovation, entrepreneurial spirit and motivation, as well as various economic and environmental factors, affect the creation of born-global (BG) companies. Design/methodology/approach: The research model was tested through logistic regression techniques to a sample obtained from the Global Entrepreneurship Monitor data set for…

External Competition Flattens the Phillips Curve

Abstract In this paper, we elaborate an open economy Phillips curve (OEPC) with micro-founded analysis, in which external competition significantly impacts the domestic inflation rate. This influence is transmitted through two channels: a) the gap between the current and potential growth of imports, and b) real exchange-rate misalignment. We estimate this OEPC by applying two…

Current-Account Imbalances, Real Exchange-Rate Misalignments, and Output Gaps

Abstract This study analyzes the relationships between domestic and foreign output gaps, current-account imbalances, and real effective exchange-rate (REER) misalignments. We first set up a theoretical framework based on the elasticities and absorption approaches of the balance of payments to derive and clarify these relationships. Next, we perform panel VAR estimates in a sample of…

The role of entrepreneur’s characteristics to be a born global firm

This paper examines how some key features of an entrepreneur lead early-stage firms (ESF) to become born globals (BG). Specifically, it focuses on human capital, the scope and novelty of the product and the opportunities of the business environment in the early stages of a firm. It contributes to the literature by focusing on some…

Incidence of cultural, economic, and environmental factors in the emergence of born-global companies in Latin America

Research Summary: This paper examines the effect of key cultural and economic factors on the emergence of born-global (BG) companies. Such factors include the intentions and the growth aspirations of the entrepreneur, as well as the country’s characteristics in terms of its income per capita and the complexity of its economic system. The analysis also highlights…

The effects of motivations to go to the country on rural accommodation choice: A hybrid discrete choice model

Based on the theory of constructive consumer choice process, we propose that the rural accommodation choice process depends on motivations of tourists to go to the country. Discrete choice models have frequently been used to explain and predict choices from a set of finite alternatives, such as the choice of accommodation, but using only cognitive…

Riche comme un argentin: desigualdad educativa en la Argentina de la belle époque

En el presente trabajo demostramos que la Argentina de la belle époque fue, de forma persistente, un país regionalmente desigual en términos de capital humano. Aunque la distribución de los maestros y de las tasas de enrolamiento mejoran significativamente entre 1883 y 1914, la distribución de las tasas de alfabetización no mejora a la par….
