Hunting High and Low for Vertical FDI   总被引:1,自引:0,他引:1  
Recently the horizontal and vertical models of foreign direct investment (FDI) have been synthesized into the knowledge‐capital (KK) model. Empirical tests, however, find that the horizontal model cannot be rejected in favor of the KK model. I suggest this is because the empirical specifications are too restrictive for vertical FDI to manifest itself. Using an alternative specification, I find evidence of vertical FDI. In particular, when I use the stock of FDI I can reject the horizontal model in favor of the knowledge‐capital model and identify countries for which FDI is dominated by vertical investment.  相似文献

Literature-related discovery (LRD) is the linking of two or more literature concepts that have heretofore not been linked (i.e., disjoint), in order to produce novel, interesting, plausible, and intelligible knowledge (i.e., potential discovery). The open discovery systems (ODS) component of LRD starts with a problem to be solved, and generates solutions to that problem through potential discovery. We have been using ODS LRD to identify potential treatments or preventative actions for challenging medical problems, among myriad other applications. The five immediately preceding papers in this Special Issue describe the application of ODS LRD to Raynaud's Phenomenon (RP), cataracts, Parkinson's Disease (PD), Multiple Sclerosis (MS), and Water Purification (WP). We describe the lessons learned from each application, and how the techniques can be improved further.Generation of much potential discovery using ODS LRD is possible when the conceptual roadblocks to discovery are removed. Some of these roadblocks include use of numerical filters that are unrelated to generating discovery, and excessive reliance on literatures directly related to the problem literature of interest. The issue of how to handle large amounts of potential discovery has not been addressed in the literature, since most ODS LRD researchers have tried to find a relatively few potential discovery items. We present a development strategy that capitalizes on the large amounts of potential discovery we have identified.  相似文献

In this article, we test to determine whether a reallocation of government budgetary components can enhance long-term GDP growth in a set of 15 EU countries. We apply panel data techniques to the period 1971–2006, and use three alternative dependent variables in a growth regression: economic growth, total factor productivity and labour productivity. Our results also identify the distortions induced by public expenditure in the private factors allocation. In particular, we detect a strong crowding-in effect associated to public investment, which has enhanced economic growth by boosting private investment. We also associate a dependence of productivity on public expenditure on social security.  相似文献

The majority of research to date investigating strategic tariffs in the presence of multinationals finds a knife-edge result where, in equilibrium, all foreign firms are either multinationals or exporters. Utilizing a model of heterogeneous firms, we find equilibria in which both pure exporters and multinationals coexist. We utilize this model to study the case of endogenously chosen tariffs. As is standard, Nash equilibrium tariffs are higher than the socially optimal tariffs. Unlike existing models with homogeneous firms, we find that non-cooperative tariffs promote the existence of low-productivity firms relative to the socially optimal tariffs. This highlights a new source of inefficiency from tariff competition not found in models of homogeneous firms. In addition, we find that in many cases the Nash equilibrium tariff when FDI is a potential firm structure is lower than when it is not. As a result, FDI improves welfare by mitigating tariff competition.  相似文献

Tax incentives offered to attract firms engaged in foreign direct investment are often tied to performance requirements such as domestic content restrictions or adherence to environmental standards. The tax competition literature has repeatedly shown that competition between municipalities for mobile firms tends to drive taxes to low levels. One would expect a comparable result for burdensome performance requirements. Despite this, the evidence suggests that while taxes have indeed been driven down, performance requirements are as popular as ever. We explain this seeming conundrum by showing that in the presence of spillovers, binding performance requirements can act as a coordination device for firms. In equilibrium, municipalities choose performance requirements, which maximize joint surplus from investment. Competition between municipalities then transfers this surplus to firms via tax subsidies.  相似文献

Consider an estimate of the common value of an auctioned asset that is symmetric in the bidders’ types. Such an estimate can be represented solely in terms of the order statistics of those types. This representation forms the basis for a pricing rule yielding truthful bidding as an equilibrium, whether bidders’ types are affiliated or independent. We highlight the link between the estimator and full surplus extraction, providing a necessary and sufficient condition for ex-post full surplus extraction, including the possibility of independent types. The results offer sharp insights into the strengths and limits of simple auctions by identifying the source of informational rents in such environments.

We are grateful for comments and suggestions from Richard McLean and Jeroen Swinkels.  相似文献

The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares.  相似文献

Aims: To assess incremental charges of patients experiencing venous thromboembolisms (VTE) across various types of elective inpatient surgical procedures with administration of general anesthesia in the US.

Methods: The authors performed a retrospective study utilizing data from a nationwide hospital operational records database from July 2014 through June 2015 to compare a group of inpatients experiencing a VTE event post-operatively to a propensity score matched group of inpatients who did not experience a VTE. Patients included in the analysis had a hospital admission for an elective inpatient surgical procedure with the use of general anesthesia. Procedures of the heart, brain, lungs, and obstetrical procedures were excluded, as these procedures often require a scheduled ICU stay post-operatively. Outcomes examined included VTE events during hospitalization, length of stay, unscheduled ICU transfers, number of days spent in the ICU if transferred, 3- and 30-day re-admissions, and total hospital charges incurred.

Results: The study included 17,727 patients undergoing elective inpatient surgical procedures. Of these, 36 patients who experienced a VTE event were matched to 108 patients who did not. VTE events occurred in 0.2% of the study population, with most events occurring for patients undergoing total knee replacement. VTE patients had a mean total hospital charge of $60,814 vs $48,325 for non-VTE patients, resulting in a mean incremental charge of $11,979 (p?<?.05). Compared to non-VTE patients, VTE patients had longer length of stay (5.9 days vs 3.7 days, p?<?.001), experienced a higher rate of 3-day re-admissions (3 vs 0 patients) and 30-day re-admissions (7 vs 2 patients).

Conclusions: Patients undergoing elective inpatient surgical procedures with general anesthesia who had a VTE event during their primary hospitalization had a significantly longer length of stay and significantly higher total hospital charges than comparable patients without a VTE event.  相似文献

Gender pairing and bargaining—Beware the same sex!   总被引:1,自引:0,他引:1  
We study the influence of gender and gender pairing on economic decision making in an experimental two-person bargaining game where the other party’s gender is known to both actors. We find that (1) gender per se has no significant effect on behavior, whereas (2) gender pairing systematically affects behavior. In particular, we observe much more competition and retaliation and, thus, lower efficiency when the bargaining partners have the same gender than when they have the opposite gender. These findings are consistent with predictions from evolutionary psychology. Implications of our results for real-world organizations are discussed.  相似文献

This article examines the relationship between the unemployment rate and the labour force participation rate in Spain. Cointegration analysis is performed for aggregate, male and female time-series. Results suggest that there is no a long-run relationship between the two variables for the aggregate and male cases. However, the findings support a long-run relationship between the two variables for the female time-series. Thus, the unemployment invariance hypothesis is supported in the two former cases but not in the latter.  相似文献
