The main contribution of this paper is a simple theoretical framework and empirical estimations explaining the behavior of the manufacturers. The paper focuses on the frequently used methods of demand estimation for discrete choice models to analyze the Iranian automobile market. It shows how both major companies in Iran choose to produce lower quality products and why they still collusively charge high markups. Empirical estimations are based on Berry, Levinsohn, and Pakes (1995) to predict marginal costs and markups. Estimation results also support the hypothesis that manufacturers are charging high markups. In addition, the counterfactual analysis carried out supports the view that both duopolist firms prefer to operate at lower quality rather than at higher quality production levels. They also collusively price their products. Furthermore, analyses are performed using the Multinomial Logit methodology to better understand the Iranian automobile market. Tastes of people with different genders and ages for some specific cars are explained, and the effects of population changes on auto demand are predicted. 相似文献

This study investigates the causes and consequences of import and export smuggling and estimates its relative size in Iran from 1970 to 2002. Multiple Indicators–Multiple Causes (MIMIC) modeling and trade misinvoicing are used to compute the latent variable of smuggling. The results indicate that the penalty rate for smuggling and the quality of economic and political institutions reduce smuggling, while tariffs and black market premia increase the incentives for illegal trade. More trade openness is associated with greater illegal trade in the case of Iran. On average, smuggling in Iran has been approximately 13% of total trade. 相似文献

Integrated multi-period cell formation and subcontracting production planning in dynamic cellular manufacturing systems 总被引:4,自引:1,他引:3
In this paper, an integrated mathematical model of the multi-period cell formation and production planning in a dynamic cellular manufacturing system (DCMS) is proposed with the aim of minimizing machine, inter/intra-cell movement, reconfiguration, partial subcontracting, and inventory carrying costs. This paper puts emphasis on the effect of the trade-off between production and outsourcing costs on the re-configuration of the cells in cellular manufacturing systems (CMSs) under a dynamic environment, in which the product mix is different from a period to another resulting in the operational dynamism in the cells. The proposed model is verified by a number of numerical examples and related sensitivity analysis. 相似文献

We explore the effect of technical progress on the endogenously determined range of non-traded goods by using a Ricardian model with continuum of goods. By defining technical progress on the basis of proportional changes in the relative productivity across sectors, we show that the range of non-traded goods decreases if technical progress is unbiased or if it is biased toward the goods that a country has more comparative advantage. 相似文献

In a differentiated duopoly model of trade and FDI featuring both horizontal and vertical product differentiation, we examine whether globalization and trade policy measures can generate welfare gains by leading firms to change their mode of competition. We show that when a high-quality foreign variety is manufactured under large frictions due to upstream monopoly power, a foreign firm can become a Bertrand competitor against a Cournot local rival in equilibrium, especially when the relative product quality of the foreign variety is sufficiently high and trade costs are sufficiently low (implying higher input price distortions due to double marginalization). Our results suggest that such strategic asymmetry is welfare improving and that the availability of FDI as an alternative to trade can make welfare-enhancing strategic asymmetry even more likely, especially when both input trade costs and fixed investment costs are sufficiently low and trade costs in final goods are sufficiently large. 相似文献

We study the response of income inequality to positive per capita oil and gas revenue shocks in Iran. Using historical data from 1973 to 2016 and vector autoregression (VAR) as well as vector error correction (VECM) model‐based impulse‐response functions, we find a positive and statistically significant response of income inequality to oil booms. We also explore possible channels through which oil booms may increase inequality, including private sector credit growth, construction investment, international trade (imports) and real economic output. We find that following an oil boom, higher imports, private sector credit growth, and real economic output can explain the increased income gap to a certain degree in Iran's oil‐based economy. Our analysis can help policymakers evaluate and accommodate the possible positive or negative effects of inequality in Iran resulting from the 2016 lifting of the embargo against the country. 相似文献

Despite the steady growth in foreign direct investment (FDI) flow into Sub-Saharan Africa (SSA), which is facilitated by the United Nations "2030 Agenda for Sustainable Development", economic development in SSA countries remains relatively weak, due in part to frequent incidents of civil violence. The critics of FDI inflow into SSA posit that the cross-border capital flow fuels civil conflict and unrest, whilst the proponents maintain that FDI inflow helps developing countries raise their economies. To reconcile these two views, this paper considers the impact of FDI on civil violence in SSA by distinguishing recipient industries of FDI. The results from a new general equilibrium theory suggest that an increase in resource-directed FDI inflow to countries where the resource sector is skilled labour (unskilled labour) intensive reduces (increases, respectively) the risk of violence. Using a panel data consisting of 34 SSA countries for 1972–2013, the dynamic panel estimates provide support for our theoretical findings. In particular, an increase in FDI inflow reduces the risk of civil violence for skilled labour intensive fuel-resource-rich SSA countries. However, the likelihood of violence can increase in FDI inflow for countries that are rich in unskilled labour intensive non-fuel, ore and other mineral resources. 相似文献

Background and aims: Infection is a serious and expensive complication of Cardiac Implantable Electronic Device (CIED) procedures. A retrospective based cost analysis was performed to estimate Trust level savings of using the TYRX antibacterial envelope as a primary prevention measure against infection in a tertiary referral centre in South London, UK.Methods: A retrospective cohort of heart failure patients with reduced ejection fraction undergoing Implantable Cardioverter Defibrillator (ICD) or Cardiac Resynchronization Therapy (CRT) procedures were evaluated. Decision-analytic modelling was performed to determine economic savings of using the envelope during CIED procedure vs CIED procedure alone.Results: Over a 12?month follow-up period following CIED procedure, the observed infection rate was 3.14% (n?=?5/159). The average cost of a CIED infection inpatient admission was £41,820 and, further to economic analysis, the additional costs attributable to infection was calculated at £62,213.94. A cost saving of £624 per patient by using TYRX during CIED procedure as a primary preventative measure against infection was estimated.Conclusions: TYRX would be a cost-saving treatment option amongst heart failure patients undergoing ICD and CRT device procedures based on analysis in the local geographical area of South London. If upscaled to the UK population, we estimate potential cost savings for the National Health Service (NHS). 相似文献

We formulate a model of mergers and acquisitions assuming a monopolistic competitive industry that exhibits agglomeration economies. We provide the conditions for the existence of a non‐trivial Nash equilibrium in the acquisition market at which the most productive firm acquires a range of less‐productive firms. Most importantly, we show that domestic merger and acquisition activities are international trade promotionary. We also show that such types of mergers and acquisition will improve the competitive position of foreign firms leading to an increase in their market share. In addition, domestic mergers and acquisitions will increase the number of imported varieties. 相似文献

This article uses a Multiple Indicators Multiple Causes (MIMIC) model to analyse the determinants of smuggling. The analysis reveals that higher corruption and a lower rule of law encourage smuggling. Tariffs and trade restrictions are important push factors, while a higher Black Market Premium (BMP) discourages smugglers. Based on the MIMIC estimates, we calculate an index of smuggling which provides a ranking for 54 countries. We find that smuggling is rampant in Cameroon, Pakistan and Kenya while it is least prevalent in Switzerland, Finland and Sweden. 相似文献
