Expanded separation portfolios ( Se ) and Treasurer’s portfolios T( Se ) are a sect of themselves. They arise out of risk-free assets and risky portfolios like other mutual funds. But their distinctive features set them apart from the common lot. This paper puts forth, firstly, a down-to-earth axiomatic that allows a complete formalization of the class of Se portfolios. Secondly, simple separation portfolios are featured and their differences with ( Se ) are highlighted. Next, the category of T( Se ) will be defined and their main properties brought to light.

Occupational Health and Safety Governance (OHSG) is a branch of Corporate Governance by which the board directs and controls labor risks created by their own enterprise. The OHSG concept is relatively new; unlike Occupational Health and Safety Management, which is mostly related to the work of managerial ranks, OHSG deals with principles, the interests of stakeholders, and the work of directors.

This paper develops a method for market definition using demand-and-supply estimations. That method is then applied to the Argentine dishwashing detergent industry, using data from the years 2022-2024. The results are compared to the ones obtained using only demand estimations, and the conclusion is that the use of supply price equations generates a considerable improvement in those results.

This article explores the emerging concept of contrast leadership and the role of the strategic sparring partner as a mechanism to mitigate the risks associated with decision-making in the C-suite. It argues that the loneliness at the top and the cognitive biases inherent in power can erode the quality of strategic decisions. Drawing on the academic and management literature, it proposes a conceptual framework for contrast leadership and distinguishes it from other approaches such as executive coaching and traditional consulting.

This paper explores Gino Germani’s further interpretations of Peronism after considering it a particular case of Fascism (see Working Paper N° 371). A visit paid to American universities in late 1956 or early 1957 put him in touch with leading sociologists, Seymour Martin Lipset among them. Lipset’s work on “working-class authoritarianism” made an impact on Germani’s views. By mid-1957 he wrote a paper on “Authoritarianism and the popular classes”, following and discussing Lipset’s views.

While existing cross-country studies on political budget cycles rely on annual data, we build a panel with quarterly and monthly data from Latin American and OECD countries over the 1980-2005 period. Disaggregated data allow to center the electoral year more precisely, and show the effects are concentrated in a three-quarter window around elections. Cycles are statistically significant only in Latin America, but the pattern is similar to OECD countries: the budget surplus/GDP ratio falls in the election period and rises in the post-election period.

Se analizan aspectos de la crisis financiera para identificar cuales fueron las principales causas que la llevaron a los límites conocidos. Es cierto que el problema encontró sus raices en el mercado de hipotecas subprime y en la falta de responsabilidad de las principales instituciones financieras. Pobres políticas económicas crearon el contexto adecuado para que la crisis tuviera los alcances que se conocen. Pero no puede dejar de considerarse el factor humano. En particular, debe tenerse en cuenta la codicia que parece haber sido el elemento común a los principales protagonistas.

Cuando cayó Roma, su vasto imperio se segmentó en muchos sentidos, incluido el lingüístico. En las regiones romanizadas el latín vulgar evolucionó de manera diferente en cada parroquia, dando lugar a una multitud de lenguas vernáculas romances. En las regiones menos romanizadas renacieron las lenguas indígenas, también muy segmentadas. Esto cambió cuando, con la introducción de la imprenta de caracteres móviles, comenzó un proceso inverso de amalgama de dialectos vernáculos. Algunos se erigieron en lenguas literarias que eventualmente reemplazaron al latín eclesiástico.
