From Bargaining Solutions to Claims Rules: a Proportional Approach

Abstract: Agents involved in a conflicting claims problem may be concerned with the proportion of their claims that is satisfied, or with the total amount they get. In order to relate both perspectives, we associate to each conflicting claims problem a bargaining-in-proportions set. Then, we obtain a correspondence between classical bargaining solutions and usual claims…

Cost Sharing Solutions Defined by Non-Negative Eigenvectors

Abstract: The problem of sharing a cost M among n individuals, identified by some characteristic ci in R+, appears in many real situations. Two important proposals on how to share the cost are the egalitarian and the proportional solutions. In different situations a combination of both distributions provides an interesting approach to the cost sharing…

Participation and solidarity in redistribution mechanisms

ABSTRACT Following Bossert (1995), we consider a model where personal income depends on two different characteristics: skills and effort. Luttens (2010) introduces claims that individuals have over aggregate income and that only depend on the effort they exert. Moreover, he proposes redistribution mechanisms in which solidarity is based on changes in a lower bound on…

Graneries (pósitos): a source of finance for Spain´s small farmers, 1900-1950.»

Abstract: Under the Ancien Régime in Spain local granaries (in Spanish, pósitos) acted as welfare institutions designed to help small farmers in times of crisis. During the first third of the twentieth century they were subject to an intense reorganisation in Spain and this transformed them into the only microfinance institution to which a significant part of the…

Net energy analysis in a Ramsey–Hotelling growth model

Abstract: This article presents a dynamic growth model with energy as an input in the production function. The available stock of energy resources is ordered by a quality parameter based on energy accounting: the “Energy Return on Energy Invested” (EROI). In our knowledge this is the first paper where EROI fits in a neoclassical growth…

Identifying the Most Relevant Lag with Runs

ABSTRACT In this paper, we propose a nonparametric statistical tool to identify the most relevant lag in the model description of a time series. It is also shown that it can be used for model identification. The statistic is based on the number of runs, when the time series is symbolized depending on the empirical…

A permutation entropy based test for causality: The volume–stock price relation’

ABSTRACT The purpose of this paper is to propose a newly developed non-parametric test for linear and nonlinear causality based on permutation entropy and to show its usefulness in analyzing the potential causal relationship between trading volume and security prices. Most of the empirical applications and tests for causality rely on using Granger causality based…

Specialization Across Goods and Export Quality

ABSTRACT This paper explores the link between specialization across goods and specialization within goods along the quality dimension. It develops a tractable many-country, many-industry Ricar- dian model with an integer number of heterogeneous firms producing each good, under a generic assumption about the distributions of firm e ciencies. In equilibrium, each country exports a range…

Rothschild strategies in non ferrous metals international markets (1830-1940)

ABSTRACT The aim of this article is to analyse the strategies employed by the Rothschilds up to 1940 to gain control and limit competition in the international non-ferrous metals markets. It examines how they opted for inelastic demand products of highly concentrated supply which lent themselves to market control (mercury, nickel, lead, and copper and…
