The present inquiry focuses on the modernization perspectives of the commodity‐exporting countries through the lens of development economics. To this end, the study adopts the Kaldorian framework to address the modernization effects, epitomized in the absorption of surplus labor. To trace the process of economic modernization, the study augments Lewis’s dualistic economy model by the extractive sector. Three different scenarios for the management of resource revenues are scrutinized. An altruistic mode, which implies a pure redistribution of the revenues among the poor swaths of the population, protracts the process of economic modernization, requires a greater amount of capital stock, and harbors a greater risk of a poverty trap. This effect is less pronounced if the modern sector is more capital‐intensive. A productive mode, which elicits full reinvestment of the commodity revenues, in contrast, accelerates the pace of economic modernization. Further, predicated on the scrutiny of a more realistic scenario, a bargaining mode, the study derives the condition for a net positive (or negative) modernization effect. The study identifies technical progress alongside capital accumulation as a further important source of economic modernization.  相似文献

Objective: Patients with relapsing-remitting multiple sclerosis (RRMS) treated with disease modifying therapies (DMTs) who continue to experience disease activity may be considered for escalation therapies such as fingolimod, or may be considered for alemtuzumab. Previous economic modeling used Markov models; applying one alternative technique, discrete event simulation (DES) modeling, allows re-treatment and long-term adverse events (AEs) to be included in the analysis.

Methods: A DES was adapted to model relapse-triggered re-treatment with alemtuzumab and the effect of including ongoing quality-adjusted life year (QALY) decrements for AEs that extend beyond previous 1-year Markov cycles. As the price to the NHS of fingolimod in the UK is unknown, due to a confidential patient access scheme (PAS), a variety of possible discounts were tested. The interaction of re-treatment assumptions for alemtuzumab with the possible discounts for fingolimod was tested to determine which DMT resulted in lower lifetime costs. The lifetime QALY results were derived from modeled treatment effect and short- and long-term AEs.

Results: Most permutations of fingolimod PAS discount and alemtuzumab re-treatment rate resulted in fingolimod being less costly than alemtuzumab. As the percentage of patients who are re-treated with alemtuzumab due to experiencing a relapse approaches 100% of those who relapse whilst on treatment, the discount required for fingolimod to be less costly drops below 5%. Consideration of treatment effect alone found alemtuzumab generated 0.2 more QALYs/patient; the inclusion of AEs up to a duration of 1 year reduced this advantage to only 0.14 QALYs/patient. Modeling AEs with a lifetime QALY decrement found that both DMTs generated very similar QALYs with the difference only 0.04 QALYs/patient.

Conclusions: When the model captured alemtuzumab re-treatment and long-term AE decrements, it was found that fingolimod is cost-effective compared to alemtuzumab, assuming application of only a modest level of confidential PAS discount.  相似文献

This study uses the basic tools of cointegration to determine whether there exists a long-term relationship between budget deficits and nominal interest rates in Germany. Maximum eigenvalue, trace, and likelihood ratio tests all affirm that there does apparently exist a long-term relationship between the budget deficit and the nominal interest rate. Accordingly, regression studies and formal causality tests have a reasonable basis for investigating whether budget deficits lead to higher interest rates in Germany.  相似文献

The literature on exchanges of information has ignored firms' entry decisions. Yet, the Federal Trade Commission recently expressed concerns that exchanges of information in business-to-business electronic platforms would adversely impact entry and, thus, consumers. When entry decisions are endogenized in a competitive Cournot model with cost uncertainty, we find results that contrast sharply with current thinking on the welfare consequences of information sharing.  相似文献

Abstract.  We explore a model where smuggling and a parallel currency market arise, owing to government restrictions that prevent agents from legally holding foreign exchange. Despite such restrictions, agents are able to diversify their savings, holding both domestic and parallel foreign cash, basing their portfolio allocation on current and prospective parallel exchange rates. We attribute movements in parallel rates to non‐fundamental uncertainty. The model generates equilibria with both positive and negative parallel premia and correlations between illegal trade and the premium. The model has the novel implication that currency speculation drives smuggling, affecting real activities in all sectors of the economy. JEL classification: F31  相似文献

Distinguishing characteristics of General Purpose Technologies (GPTs) are identified and definitions discussed. Our definition includes multipurpose and single-purpose technologies, defining them according to their micro-technological characteristics, not their macro-economic effects. Identifying technologies as GPTs requires recognizing their evolutionary nature, and accepting possible uncertainties concerning marginal cases. Many of the existing ‘tests’ of whether particular technologies are GPTs are based on misunderstandings either of what GPT theory predicts or what such tests can establish. The development of formal GPT theories is outlined, showing that only the early theories predicted the inevitability of GPT-induced showdown and surges. More recent GPT theories, designed to model the characteristics of GPTs, do not imply the necessity of specific macro effects. We show that GPTs can rejuvenate the growth process without causing slowdowns or surges. We conclude that existing criticisms of GPT theory can be resolved and that the concept remains useful for economic theory.  相似文献

This article analyses management–union–worker relations in a foreign‐owned Moldovan clothing factory. Studies of post‐socialist industrial relations have focused on explaining labour quiescence, advancing ‘path dependence’ and ‘Soviet legacy’ arguments. These draw attention to strong links between management and unions, and weak relations between the latter and workers. We show how the union has, in one case, drawn creatively on Soviet legacies to develop strong articulation between itself and women workers. This was part of a wider adaptive strategy within which the union transformed the meaning of previous functions and developed novel ones. The outcome is a well‐organized representative union capable of challenging management at the negotiating table, as well as on the shop floor. This seems unlikely to be universal but equally unlikely to be unique.  相似文献
