Firm Performance and Foreign Direct Investment: Evidence from Transition Economies

Firm Performance and Foreign Direct Investment: Evidence from Transition Economies Mahmut Yasar, University of Texas at Arlington, and Catherine J. Morrison Paul, University of California, Davis* Abstract We evaluate the performance of foreign-owned versus domestic firms, and the spillover effects of industry foreign share for five transition economies, namely Poland, Moldova, Tajikistan, Uzbekistan, and the Kyrgyz Republic. We find higher productivity, capital intensity, export and import shares, employment, and wages for firms with foreign ownership. Further, we find that industry presence of foreign affiliates of multinational firms leads to performance improvements for domestic firms that is, spillovers from foreign firms benefit domestic firms in these transition economies.Eastern Europe and Central Asia

The Impact of Helping Others in Coopetitive Crowdsourcing Communities

Organizations are increasingly engaging the community through crowdsourcing platforms to evolve innovative solutions to challenging business problems. Participants on such platforms often simultaneously cooperate and compete with one another to earn top honors. This paper addresses the imperative to understand the dynamics of knowledge sharing in such a coopetitive environment. Specifically, our study relies on the conceptual foundations of social exchange and social capital theories to investigate how help rendered (e.g., exchanging ideas or sharing knowledge) by participants in an online coopetitive crowdsourcing setting affects their performance. Furthermore, the study examines the moderating effects of the intensity of competition. Results of our econometrics analyses suggest that help given in a highly competitive contest, as opposed to a less competitive one, is more likely to be reciprocated, but less likely to improve the contributor’s contest performance. In addition, our study found that help received by participants positively impacts their contest performance, and partially mediates the relationship between help rendered and contest performance. This research also provides insight into what motivates participants to share knowledge under conditions of coopetition. The findings of our study have strong implications for both theory and practice

Renal replacement therapies in the aftermath of the catastrophic Marmara earthquake

Renal replacement therapies in the aftermath of the catastrophic Marmara earthquake.BackgroundRenal replacement therapy is of vital importance in the treatment of crush syndrome victims, who are frequently encountered after catastrophic earthquakes. The Marmara earthquake, which struck Northwestern Turkey in August 1999, was characterized by 477 victims who needed dialysis.MethodWithin the first week of the disaster, questionnaires containing 63 clinical and laboratory variables were sent to 35 reference hospitals that treated the victims. Information considering the features of dialyses obtained through these questionnaires was submitted to analysis.ResultsOverall, 639 casualties with renal complications were registered, 477 of whom (mean age 32.3 ± 13.7 years, 269 male) needed dialysis. Among these, 452 were treated by a single dialysis modality (437 intermittent hemodialysis, 11 continuous renal replacement therapy and 4 peritoneal dialysis), while 25 victims needed more than one type of dialysis. In total, 5137 hemodialysis sessions were performed (mean 11.1 ± 8.0 sessions per patient) and mean duration of hemodialysis support was 13.4 ± 9.0 days; this duration was shorter in the non-survivors (7.0 ± 8.7 vs. 10.0 ± 9.8 days, P = 0.005). Thirty-four victims who underwent continuous renal replacement therapy had higher mortality rates (41.2 vs. 13.7%, P < 0.0001). Only eight victims were treated by peritoneal dialysis, four of whom also required hemodialysis or continuous renal replacement therapy. The mortality rate in the dialyzed victims was 17.2%, a significantly higher figure compared to the mortality rate of the non-dialyzed patients with renal problems (9.3%; P = 0.015).ConclusionSubstantial amounts of dialysis support may be necessary for treating the victims of mass disasters complicated with crush syndrome. Dialyzed patients are characterized by higher rates of morbidity and mortality

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

A Causal Relationship Between Exports and Productivity at the Plant Level: The Case of Turkey

224 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2002.On the policy front, suggestions in regards to the causal relationship between exports and productivity following our findings must consider that industries have different structures and dynamics, thus they learn by exporting to different extents. However, the effects of productivity on exports are realized regardless of the industry. Thus, exports can be expanded by improving the productivity of plants.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD

"The Relationship between Exports and Productivity at the Plant level in the Turkish Apparel and Motor Vehicle Parts Industries

We investigate the relationship between exports and productivity in the Turkish apparel and motor vehicle and parts industries from 1990-1996, using two different models for plant-level panel data. In the first model, we examine the effect of past export status on current productivity both with and without controlling for the export history of plants. Our results show that the plants' prior market experience is a factor in their current productivity. The learning effects are evident among continuing exporters and entrants. This model, however, neither controls for the endogeneity of the explanatory variables nor for the unobserved plant-specific effects that persist over time. Moreover, it does not distinguish between the long- and short-run relationships between exports and productivity. Thus, a second model, an Error- Correction specification for panel data, is estimated to address these three issues. Our findings suggest that there is a bidirectional relationship between exports and productivity both in the short- and long-run. The effect of productivity on exporting is much stronger than the effect of exporting on productivity, suggesting that more productive firms enter the export market, then they experience a productivity enhancement due to their participation in the export marketProductivity, Multilateral Index, Exports, Causality, Error-Correction Model, Dynamic Panel Data Estimator, System GMM.
