Habit formation and strategic interactions: A new gain from trade?

A two-period duopoly model of trade with habit formation displays a “pre-entry pro-competitive effect” and the standard pro-competitive effect once trade is effective. Both effects are driven in a different way by transport cost. A trade liberalization affects ambiguously welfare.     

Use values and exchange values in Marx’s extended reproduction schemes

Abstract

Marx-Engels’ numerical illustrations of the extended reproduction suggest that a two-sector economy reaches a balanced growth path, from the second period onwards. We explain this surprising result and show that for technical reasons, disproportions between sectors can prevent the system from reproducing itself. But, in Marx’s reproduction schemes, such a crisis is not only due to purely technical factors and one must wonder what role is played by the relative price in the reproduction of the system. The answer is given by comparing two models having a similar structure but quite different rules for the determination of the relative price. In Marx’s model, the price is given by the labour values and thus, it is exogenously fixed. We contrast Marx’s analysis with an endogenous price model in which the price depends on the conditions of the accumulation of capital. The Appendices point out the complete accordance of Engels’ corrections with Marx’s model and Marx’s unfruitful quest for a balanced growth path as a tool for the analysis of crises.     

A critical note on “This time is different”

This article is structured as follows: the first section is based on Reinhart and Rogoff’s seminal papers (Am Econ Rev 98(2):339–344, 2008a, b, Am Econ Rev 99(2):466–472, 2009a, This time is different: eight centuries of financial folly, Princeton University Press, Princeton, 2009b, Am Econ Rev 100(2):573–578, 2010) and text book (2009), which today constitute the new cornerstones of conventional wisdom on the recurrence of financial crises throughout History, their development and aftermath. We deliver a critical view of this attempt to infer some systematic empirical relationship between debt, growth and inflation and underline the absence of core variables in this historical analysis. In Sect. 3, we go back 10 years to illustrate that conventional wisdom was much different at that time, emphasizing the peculiarity of each episode of the financial crises. This raises the issue of the relevancy of the cliometric approach to identify regularities down through History: so, should we trust cliometricians?     

A Theory of Favoritism in an International Oligopoly*

This paper offers an explanation of the fact that some foreign firms are favored at the expense of others, and characterizes the distribution of favors in terms of the cost parameters of firms. We present a model where favors must be bought: they come from competing contributions. This model is compared with a benchmark model with a benevolent government. We show how the distribution of favors in the favor‐seeking model deviates from the distribution that would be obtained if the government were really benevolent.     

More or Less Ambition in the Doha Round: Winners and Losers from Trade Liberalisation with a Development Perspective

What is at stake in the standoff and suspension of the Doha Round of trade talks? What impact would an agreement based on greater or lesser levels of ambition have on developing countries, whose economies are relatively dependent on agriculture? Using the MIRAGE computable general equilibrium model of the global economy, in this article we compare different scenarios for the Doha agricultural and NAMA negotiations, taking real numbers from the proposals on the table from the United States (US) and the European Union (EU) in December 2005. The results for both scenarios demonstrate the high stakes for successful completion of this negotiation given the positions articulated by the countries involved. A cooperative reform outcome by the US and the EU – based on the most ambitious components of their negotiating proposals – delivers noticeably more benefits than an unambitious outcome. We measure the degree of ambition in each scenario by the construction of a Mercantilist Trade Restrictiveness Index and focus the analysis on the impacts on developing countries.     

Stochastic rationality and Möbius inverse

Discrete choice theory is very much dominated by the paradigm of the maximization of a random utility, thus implying that the probability of choosing an alternative in a given set is equal to the sum of the probabilities of all the rankings for which this alternative comes first. This property is called stochastic rationality. In turn, the choice probability system is said to be stochastically rationalizable if and only if the Block–Marschak polynomials are all nonnegative. In the present paper, we show that each particular Block–Marschak polynomial can be defined as the probability that the decision-maker faces the loss in flexibility generated by the fact that a particular alternative has been deleted from the choice set.     

Technology and trade: Empirical evidences for the major five industrialized countries

Technology and Trade: Empirical Evidence for the Major Five Industrialized Countries. — The conclusion that prices alone cannot explain the major disturbances in trade market shares emerges from many empirical studies on international trade flows. This paper aims at introducing supply-side variables in market shares equations, namely R&D expenditures and gross fixed capital formation, along the lines of the new theory on international trade and of the literature on technology and trade relations. The empirical work is carried out on the major five industrialized countries and on twenty manufacturing industries. The results show that the supply-side variables have played a crucial role over the last decade.     

Management and cost analysis of cancer patients treated with G-CSF: a cohort study based on the French national healthcare insurance database

Objectives: To describe the management and costs associated with G-CSF therapy in cancer patients in France.

Methods: This study analyzed a representative random population sample from the French national healthcare insurance database, focusing on 1,612 patients with hematological or solid malignancies who were reimbursed in 2013 or 2014 for at least one G-CSF treatment dispensed in a retail pharmacy. Patient characteristics and treatment costs were analyzed according to the type of cancer. Then the costs and characteristics of patients associated with the use of different G-CSF products were analyzed in the sub-set of breast cancer patients.

Results: The most frequent malignancies in the database population were breast cancer (23.3%), hematological malignancies (22.2%), and lung cancer (12.4%). The reimbursed G-CSF was pegfilgrastim in 34.1% of cases, lenograstim in 26.7%, and filgrastim in 17.9%. More than one G-CSF product was reimbursed to 21.3% of patients. The total annual reimbursed health expenses per patient, according to the type of G-CSF, were €27,001, €24,511, and €20,802 for patients treated with filgrastim, lenograstim, and pegfilgrastim, respectively. Ambulatory care accounted for, respectively, 35%, 38%, and 41% of those costs. In patients with breast cancer, ambulatory care cost was €7,915 with filgrastim, €7,750 with lenograstim, and €6,989 with pegfilgrastim, and the respective cost of G-CSF was €1,733, €1,559, and €3,668.

Conclusion: All available G-CSF products have been shown to be effective in cancer patients, and both daily G-CSFs and pegylated G-CSF are recommended in international guidelines. Nevertheless, this analysis of G-CSF reimbursement indicates that the choice of product can markedly affect the total cost of ambulatory care.
