Abstract [EN]The article reports the issues corresponding to the climate variability and possibility of droughts in spatially distinct regions of Paraguay, the Chaco and the Oriental (Paraná Basin). Based on the GMT scripting approach and high-resolution datasets from the TerraClimate and...

Historians of the social sciences and historians of economics have come to agree that, in the United States, the 1940s transformation of economics from political economy to economic science was associated with economists' engagements with other disciplines — e.g. mathematics, statistics,...

Measurement is a special type of evaluation more exact than opinion or estimation. Sawyer, Sankey and Lombardo (2013) characterized a measure as satisfying five invariance and continuity conditions. Those conditions are satisfied as the result of a process of convergence towards that measure....

We develop a unified framework with schools and residential choices and study the welfare and distributional consequences of switching from the traditional neighborhood assignment to the celebrated Deferred Acceptance mechanism. We show that when families receive higher priorities at...

The present work applies several advanced spectral methods to the analysis of macroeconomic fluctuations in three countries of the European Union: Italy, The Netherlands, and the United Kingdom. We focus here in particular on singular-spectrum analysis (SSA), which provides valuable spatial and...

We build a simple dynamic structural model of the firm, with state variable being earnings. It can address general empirical levels of investment, dividends, equity issuance in distress, leverage, debt duration, and liquidation/bankruptcy. Firms with very low leverage carry a substantial...

We generalize the concept of K-convexity to an n-dimensional Euclidean space. The resulting concept of K-convexity is useful in addressing production and inventory problems where there are individual product setup costs and/or joint setup costs. We derive some basic properties of K-convex...
