A logistic regression-based pairwise comparison method to aggregate preferences

In a group decision making process, several individuals or a committee have the responsibility to choose the best alternative from a set. The problem addressed in this paper is how to aggregate personal preferences to arrive at an optimal group decision. New technologies allow individuals that may seldom or never meet to make group decisions. This paper proposes a methodology to obtain the group preference ordering in two steps. Firstly, each individual studies the problem isolated, and then, in a possibly virtual meeting, the group must agree on the preferences on some pairs of alternatives. Then, the group criterion is achieved by using a logistic regression model within the pairwise comparison framework proposed here. Properties of the procedure are studied and two illustrative examples are presented.     

Development of the banking system under the Estonian currency board

The choice of a suitable exchange rate regime is the subject of numerous discussions in economic literature. Estonia has been successful in achieving economic stabilization and growth and steadily declining inflation. It has one of the highest per capita foreign direct investments in central and eastern Europe. Estonia also has one of the most liberalized economies among all transition countries. An essential element of the success of Estonian economic development is strict exchange rate control. Estonia has adopted a currency board that serves as a signal of commitment to prudent monetary policy and as a guarantee of sound money during the transition period. This paper discusses the experience of operating the currency board, some future prospects of the currency board arrangement, and the development of the banking system in Estonia.     

Cash flow effects on economic growth

Policy makers have traditionally considered the macroeconomic relations and the variables that can affect the economic objectives that they pursue, such as prices, employment, balance of payments, and economic growth. Recently, microeconomic behavior has also been considered. To complete the analysis, it is necessary to include those variables that define the firm's evolution and activities, and cash flow could be this kind of variable to be included in the analysis. The main objective of this paper is to show the relationship between cash flow and one of the final economic policy targets, economic growth. This paper considers the relationship between cash flow and applied economics, then develops the effects of cash flow on economic growth.     

Optimal designs for generalized linear models with biased response

This paper is concerned with the search for locally optimal designs when the observations of the response variable arise from a weighted distribution in the exponential family. Locally optimal designs are derived for regression models in which the response follows a weighted version of Normal, Gamma, Inverse Gaussian, Poisson or Binomial distributions. Some conditions are given under which the optimal designs for the weighted and original (non-weighted) distributions are the same. An efficiency study is performed to find out the behavior of the D-optimal designs for the original distribution when they are used to estimate models with weighted distributions.     

Does foreign aid really raise per capita income? A time series perspective

Abstract. We analyze the relationship between per capita income and foreign aid. We employ annual data and five‐year averages and carefully examine the time‐series properties of the data. Panel estimations with dynamic feasible generalized least‐squares (DFGLS) show that aid generally has an insignificant or minute negative significant impact on per capita income (particularly in highly aid‐dependent countries). This holds true for countries with different levels of human development and income, as well as for different regions. We also find that aid has a small positive impact on investment, but a significant negative impact on domestic savings (crowding out) and the real exchange rate (appreciation).

How does working capital management affect the profitability of Spanish SMEs?

This paper analyzes the relation between working capital management and profitability for small and medium-sized enterprises (SMEs) by controlling for unobservable heterogeneity and possible endogeneity. Unlike previous studies, we examine a non-linear relation between these two variables. Our results show that there is a non-monotonic (concave) relationship between working capital level and firm profitability, which indicates that SMEs have an optimal working capital level that maximizes their profitability. In addition, a robustness check of our results confirms that firms?? profitability decreases as they move away from their optimal level.

Mergers Along the Global Supply Chain: Information Technologies and Routine Tasks

This paper empirically analyses how the adoption of Information Technologies (IT) has changed the organization of global supply chains. We focus on international mergers, which are a growing and important component of foreign direct investment. We use data on North–South mergers and acquisitions (M&As). We show that the effect of IT adoption on the number of vertical M&As is decreasing with the routine intensity of the industry. Our interpretation is that the IT revolution enabled new monitoring mechanisms. This allowed Northern headquarters to better monitor suppliers, especially those in less routine‐intensive industries –which were harder to monitor before.
