Microdata analysis of the consequences of free trade port policy: the case of Iran free zones

ABSTRACT

Creating free trade zones as a policy to motivate new investment and improve the local economic indicators might be of some benefits. Following of this policy in Iranian major port, however, resulted vice versa by aggravating the current account balance that is higher imports and the same horizon diminished export sums. We derive the micro data of trade for the Iranian major Imam port according to code arrangements of harmonic system (HS), which permits the clustering of different goods categories. Then we extracted the sums of survey data for the years before and after Imam port became free trade zone and applied fixed effect difference in difference (DID) method to capture the heterogeneity of unobserved variables. Our control port of analysis was Rajaee port the policy did not implemented. Results show that just as Imam free port’s Current Account Balance deteriorated by increasing import and dampening of export sums.     

Do oligopolistic firms benefit from being forced to act non-strategically?

The present study seeks to answer the question of whether acting non-strategically can benefit firms. In a static Cournot framework, if a subset of firms are constrained to the equilibrium level of output, being non-strategic will have no impact on profits of neither constrained nor strategic firms and provided that sufficiently large number of firms are restricted, a marginal quantity contraction can be to their benefit. In contrast, using a dynamic Cournot framework, we find that the constraint set at the equilibrium level or moderately deviated from it, leads to increased profits for all firms irrespective of the number of non-strategic ones.     

Disentangling the effect of services on B2B firm value: Trade-offs of sales,profits, and earnings volatility

In the face of declining business and growing pressures from low-cost competitors, many business-to-business (B2B) manufacturers have moved from their previously successful product-centric strategies to more service-oriented business models. Yet despite their substantial investments in services, firms fail to understand the performance ramifications of these offerings. With a longitudinal data set (2001–2016) of 227 B2B manufacturers listed in the S&P 1500 index, this study disentangles the simultaneous effects of financial-based mechanisms that link the service ratio (i.e., share of a firm's revenue generated from selling services) to firm value. The findings reveal significant trade-offs across these mechanisms. Although the service ratio monotonously boosts sales growth, it has U-shaped curvilinear relationships with profitability and earnings volatility. These effects also depend on industry- and firm-level factors. Industry maturity positively moderates the effects of the service ratio on sales growth and profitability. However, business scope has an adverse effect on the service ratio–profitability relationship. Finally, industry turbulence negatively moderates the effect of services on earnings volatility.     

Consumer power and choice deferral: The role of anticipated regret

This paper examines the influence of social power on consumers' propensity to defer choice. Based on the notion that elevated power reduces regret anticipation—the fear of making a wrong choice—it is proposed that power influences the extent of choice deferral by reducing consumers' susceptibility to anticipated regret. Because of the regret-based mechanism, power can increase or decrease consumers' propensity to defer choice, depending upon the situational factors that are associated with anticipated regret, such as salience of regret, outcome reversibility (e.g., return policy), and locus-of-regret (postponing vs. choosing now). Using different manipulations of power, seven studies provide consistent support for the proposed effects and show that situational factors and marketing strategies can induce, turn off, or even reverse the effect of power on deferral. Theoretical contributions and managerial implications are discussed.     

What happened to complex product systems literature over the last two decades: progresses so far and path ahead

Complex product systems (CoPS) industries largely contribute to industrial development, economic growth and creation of national wealth in both developed and developing economies. CoPS also show a number of specific characteristics as a distinctive category of industrial products in comparison with mass-produced consumer goods. These aspects have attracted the attention of scholars to study CoPS over the last two decades, resulting in a fairly extensive body of literature on the subject. However, there is a further need to connect research findings in this area, to illustrate a macro view of the development in the field, explore common themes, and identify possible paths into the future. This study aims to contribute to these ends by: (i) exploring the quantitative aspects of the CoPS literature; (ii) illustrating topical classification of CoPS studies and their findings; and (iii) suggesting opportunities for future research through examining common trends and unresolved issues in the literature.     

Private and Givernment Investment: A Study of Three OECD Countries

This paper examines the relationship between private investment and government spending in Australia, Britain and the United States. Since all time series data are stationary in first difference and cointegrated, these series are represented by an error correction model. Variance decomposition and impulse response functions are employed to investigate the effects of government spending on private investment. Generally the empirical results provide limited support for "crowding out" effects of government investment on private investment. The rate of interest and the corporate profit ability showed significant effects on private investment in two out of three cases. [E62, E63]     

Guidelines-based treatment associated with improved economic outcomes in nontuberculous mycobacterial lung disease

Abstract

Background: The prevalence of nontuberculous mycobacterial lung disease (NTMLD) in the US has increased; however, data characterizing the associated healthcare utilization and expenditure at the national level are limited.

Objective: To examine associations between economic outcomes and the use of anti-Mycobacterium avium complex (MAC) guidelines-based treatment (GBT) for newly-diagnosed NTMLD in a US national managed care claims database (Optum^® Clinformatics^® Data Mart).

Methods: NTMLD was defined as having ≥2 claims for NTMLD (ICD-9 031.0; ICD-10 A31.0) on separate occasions ≥30?days apart (between 2007 and 2016). The cohort included patients insured continuously over a period of at least 36?months (12?months before initial NTMLD diagnostic claim and for the subsequent 24?months). Treatment was classified as GBT (consistent with American Thoracic Society/Infectious Diseases Society of America guidelines), non-GBT, or untreated. All-cause hospitalization rates and total healthcare expenditures at Year 2 were assessed as outcomes of the treatment prescribed in Year 1 after NTMLD diagnosis.

Results: A total of 1,039 patients met study criteria for NTMLD (GBT, n?=?294; non-GBT, n?=?298; untreated, n?=?447). After adjustment for baseline characteristics, GBT was associated with a significantly lower all-cause hospitalization risk vs non-GBT (odds ratio [OR]?=?0.53; 95% CI = 0.33–0.85, p?=?0.008), and vs being untreated (OR = 0.57; 95% CI = 0.35–0.91, p?=?0.020). Adjusted total healthcare expenditure in Year 2 with GBT ($69,691) was lower than that with non-GBT ($77,624) with a difference of ?$7,933 (95% CI = ?$14,968 to ?$899; p?=?0.03).

Conclusions: Patients with NTMLD in a US managed care claims database who were prescribed GBT had lower hospitalization risk than those who were prescribed non-GBT or were untreated. GBT was associated with lower total healthcare expenditure compared with non-GBT.     

Developing a model to evaluate the impacts of science,technology and innovation foresight on policy-making

Technology foresight as a policy intelligence tool can offer vital inputs for policy-making in various domains. The relationship between foresight and policy-making has been presented in the literature by the policy-related functions of foresight, but the literature reflects a theoretical gap with the systematic evaluation model for the impact of foresight on policy-making. This research seeks to bridge the existing gap and uses the mixed method for this purpose. The mixed method approach used in this paper is the sequential exploratory design. First, the conceptual model is developed in the qualitative part of this research by using meta-synthesis and constant comparative method (CCM) of analysis. Second, in the quantitative part, quantitative tests are used to evaluate the dimensions and components of the developed theoretical model. The data collection tool is a questionnaire. The results confirm the proposed dimensions of the evaluation model.
