It is commonly asserted that unfair trading practices (UTPs) emerge largely as a result of contract incompleteness. In line with this view it is claimed that making contracts more complete will represent an antidote to UTPs. In this paper we argue that this does not need to be the case. This is because contracts, except for their potential to increase the surplus generated in the transaction, determine how this surplus will be divided. This, in turn, makes it possible for both trading partners to use contractual terms to turn the distributional conflict to their advantage. In the presence of unequal distribution of bargaining power this may lead to a situation in which the stronger party may succeed in tilting the contract in its favour by including UTPs in the contract content. Drawing insights from data collected in 2017 through a field survey among dairy farmers in France, Germany, Poland and Spain, we find support for this argument. Our estimation results show that contract completeness increases the likelihood of farmers reporting that their contracts with processors include the practices that may be considered as UTPs. Further, and also in line with this argument, contract completeness does not seem to affect UTPs during the contract execution or its termination. 相似文献

The purpose of this paper is to investigate the causal relations between nominal exchange rates and monetary fundamentals. The analysis is conducted using panel quarterly data from the period 2001–12 for Central and Eastern European countries (including Turkey) with relatively flexible exchange rate regimes. The paper reconnects the empirical literature on exchange rates in Central and Eastern European countries with the most recent findings on exchange rate determination in advanced economies. Kóyna's approach, which accounts for linkages between countries, is used in the study. The main findings indicate the existence of causal relations running from both nominal exchange rates to monetary fundamentals and in the opposite direction as well as the existence of a relatively strong link between exchange rates and differentials in the relative price of non‐tradables. 相似文献

Euro-area accession caused boom-bust cycles in several catching-up economies. Declining interest rates and easier financing conditions fuelled spending and borrowing from abroad. Over time inflation deteriorated external competitiveness, turning the boom into a bust. We ask whether such a scenario can be avoided using macroeconomic tools that are available in the period of joining a monetary union: central parity revaluation, fiscal tightening or increased taxation. We find that exchange rate revaluation is the most attractive option. It simultaneously trims the expansion of output and domestic demand, reduces the cost pressure and ranks first in terms of welfare. 相似文献

The paper characterizes main trends in ICT implementation and diffusion in the CEE countries in terms of market volume, economic development and ICT trade integration within the EU market. The analysis reveals a gradual closing up of the technology gap in ICT sector between the CEE and the ‘old’ EU countries. The focus is on the relationship between ICT expenditure, NRI index, vs GDP per capita, competitiveness and productivity. The evolution of ICT development trajectory is traced analysing the changing pattern of ICT trade between the CEE countries and the EU. The impact of the current crisis on the structural adjustment of the CEE ICT sector is assessed from the perspective of Schumpeterian technology gap and catching up. 相似文献

In this paper, a balanced incomplete split-block design (BISBD) is shown to be universally optimum for the estimation of
the interaction effects with respect to each of the intra-plot stratum estimation and the GLSE. Furthermore, the efficiency
factor of an optimal design is investigated. 相似文献

The usual ordering of linear experiments is defined by quadratic risk of attainable linear estimators. It is shown that under
normality assumption this ordering can be introduced in a risk-free way by stochastic ordering of the estimators. Moreover
an application of Schur-convex functions to design of experiments is presented.

The transition from a centrally planned economy to a market economy in Poland has caused dynamic changes in the number and structure of potential investors of the stock exchange market. This phenomenon, unknown in the past, needs a new approach to statistical methods of stock market analysis. The paper presents two methods of optimal portfolio construction. The first one leads to the square programming problem. Applying the Lagrange multipliers, we obtain a system of algebraic equations which can be solved by the special algorithm proposed in the paper. The second method reduces the mentioned above square program to the linear programming problem which can be solved using the simplex method. 相似文献

The basics of portfolio management theory and methods of efficient selection of assets and their financing have been created by Markowitz and Sharpe. They propose that risk diversification consists, generally speaking, of the increase in the number of securities in a portfolio. So, authors try to answer the question of how many securities have to be bought on a given market to assure a well-diversified portfolio, where the increase in the number of securities does not lead to a significant decrease in portfolio risk. To evaluate such a purpose on the Polish capital market, 20 companies were surveyed that are included in the WIG20 index in the period January 2–October 10, 2001. The returns were estimated on a weekly basis. The research shows that a portfolio of securities constructed, according to the Sharpe Model, has a wide application to the Polish capital market.*University of Szczecin—Poland.
