The Heterogeneity of MNC' Subsidiaries and Technology Spillovers: Explaining positive and negative effects in emerging economies
Conventional models of multinational corporation (MNC) related spillovers in host economies assume that they derive from the technological assets created at the headquarters. Subsidiaries' activities in the host economy are not given any role in this process. In this paper, drawing on recent advances in MNC literature, we propose an alternative model. In this alternative model the local innovative activity of subsidiaries plays a critical role in accounting for both the possibility of positive or negative effects. More specifically, we distinguish between three types of subsidiaries: "competence creating", "competence exploiting" and passive; and explore conceptually and empirically the spillover effects of each type. Our results confirm our predictions that, in less advanced contexts such as India, only creative subsidiaries have a positive effect on host country firms; that competence exploiting subsidiaries generate negative effects when domestic firms are more advanced; and passive subsidiaries have no effects. The implications for theory and policy are discussed.Technological spillovers, MNCs, emerging economies, subsidiaries heterogeneity
Intrinsic Localized Modes of a Classical Discrete Anisotropic Heisenberg Ferromagnetic Spin Chain
We report several exact intrinsic localized mode solutions of the classical
spin evolution equation of a one-dimensional anisotropic Heisenberg
ferromagnetic spin chain in terms of Jacobian elliptic functions. These include
one, two and three spin excitations. All these solutions have smooth
anticontinuum limits. Their linear stability and semiclassical quantization are
also discussed briefly.Comment: 19 pages, 7 figures, accepted for publication in Physics Letters A on

Enhanced synchronization in an array of spin torque nano oscillators in the presence of oscillating external magnetic field
We demonstrate that the synchronization of an array of electrically coupled
spin torque nano-oscillators (STNO) modelled by
Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation can be enhanced appreciably
in the presence of a common external microwave magnetic field. The applied
microwave magnetic field stabilizes and enhances the regions of synchronization
in the parameter space of our analysis, where the oscillators are exhibiting
synchronized oscillations thereby emitting improved microwave power. To
characterize the synchronized oscillations we have calculated the locking range
in the domain of external source frequency.Comment: Accepted for publication in Europhysics Letters (EPL
Foreign Direct Investment and Technology Spillovers: Evidence from The Indian Manufacturing Sector
During the recent period, we observe that many countries compete with each other to attract foreign investment. When MNCs invest in a host country, it is assumed that a part of their technology spills to the host country firms. But the empirical studies on spillover effects of FDI have failed to find robust empirical results about the possibility of positive spillover effects. This study is an attempt to empirically examine the spillover effects from the entry of foreign firms using firm level data of Indian manufacturing industries for the period 1994-2002. We consider both the horizontal and vertical spillover effects of FDI. Consistent with the findings of the previous studies, we find no evidence of significant horizontal spillover effects. In contrast, we find negative vertical spillover effects, although it is not statistically significant.Foreign Direct Investment, Horizontal Spillover, Vertical Spillover, Panel Data
Concentration in Knowledge Output:A Case of Economics Journals
Journals moderate knowledge activity in economics. The activity of publishing article in professional journal forms significant part of knowledge output. Output of economics articles has been growing over the time. We examine an important question: Is there any case of institutional or location concentration in knowledge production? This paper analyses concentration indicators specific to economics journals and explores link between publication process and concentration. The analysis of various concentration measures present evidence for institutional-geographic-area-author concentration in Knowledge production in Economics. High concentration levels indicate possibility of institutional lock-in. The literature provides evidence for myopic refereeing, editorial favouritism and the presence of ‘lock-in’ effect. The achievement in journal publication is influenced by factors like institutional affiliation, propitious circumstances etc. Discussion carried out in this paper hints the possibility of causal link between unfair process and unfair outcome.Knowledge,Lotka's Law,Fourier Series
Field Screening of Lentil Genotypes Against Aphid Infestation in Inner Tarai of Nepal
Twenty lentil (Lens culinaris Medik) genotypes received from Grain Legumes Research Program, Khajura, Banke were screened for relative tolerance against aphid (Aphis craccivora Koch.) at the research field of National Maize Research Program, Rampur, Chitwan during winter seasons of two consecutive years 2016 and 2017. The design of the experiment was Randomized Complete Block having three replications. The unit plot size was 4m × 1 m with 25cm row to row spacing and continue plant to plant spacing was maintained and net harvested plot was 4 square meters. The recommended dose of fertilizer was 20:40:20 N:P2O5:K2O kg/ha and seed rate 30 kg/ha. Insect data were collected based on aphid population found at apical twigs (10 cm) per plant and scoring was done during flowering and pod formation stage. The grain yield was recorded. All screened genotypes differed significantly (p<0.05) on aphid population and grain yield. Genotypes, ILL 9924, RL 83, ILL 10856, ILL 6458 and RL 67 were less susceptible with higher grain yield. These results have important implications for the development of aphid tolerant high yielding lentil variety in inner Tarai of Nepal
MNEs and Export Spillovers : An Analysis of Indian Manufacturing Industries
In the present study, we try to provide some empirical evidence for the export spillover effect examining the case of an emerging economy, namely India using firm level data for the period 1994-2006. We disentangle different spillover channels, namely export spillover, R&D spillover and wage spillover. We also consider the heterogeneous technological behaviour of local firms considering how in-house R&D efforts and disembodied technological imports may affect the overall exporting performance. Our findings mainly confirm that the two most important channels for export spillover are mainly the demonstration effect and the R&D spillover effect The decision to export is influenced mainly by technological activities of local firms, confirming that R&D is a key variable that help firms to overcome fixed costs that are crucial to start exporting. Moreover, the findings of the analysis suggest that local firms R&D is highly relevant to internalize the positive spillover effect emanating from MNEs both with regard to decision to export and export propensity.exports, FDI spillover, MNEs
FDI, EXPORT SPILLOVER AND FIRM HETEROGENEITY - AN APPLICATION TO THE INDIAN MANUFACTURING CASE
The role of Foreign Direct Investments (FDI) in the process of economic development is of particular relevance since they bring in some specific technological assets that are not immediately available in the host country. The literature related to the microeconomic impact of FDI has been mainly concentrated in explaining the final effect on productivity, caused by the fact that Multinational Enterprises (MNEs) are not completely able to protect their superior assets from spilling over. However, there is a relatively unexplored effect that has recently been at the center of some studies that is the export spillover effect. Up to now, the literature has found out only mixed results with regard to the possibility that MNEs influence both export decision and export intensity of local firms. In the present paper, we provide some empirical evidence for that specific effect examining a case of an emerging economy, namely India for the period 1994-2006 by using a firm level dataset of more than 3000 firms belonging to manufacturing industries. In particular, we introduce the theoretical argument related to the MNEs heterogeneity which has not been properly investigated especially in empirical studies trying to understand whether, by using different measures characterizing MNEs behaviour, it is possible to distinguish between different impacts that MNEs have on export performance of local firms. We estimate the model through the Heckman selection technique after having built spillover variables that take into account five types of heterogeneity: the degree of involvement in trade networks, the level of embeddedness inside the innovation system of the host country, the asset seeking vs asset exploiting motivations(technological intensity), the type and amount of inputs sourced from abroad rather than from the host country and the percentage of the foreign equity stake. The second step of the analysis we perform is that of testing the relationship between the heterogeneity of MNEs with the heterogeneity of local firms splitting the sample according to the level of R&D intensity, the level of embeddness into the innovation system and the involvement in trade activities. Results confirm the hypothesis of different impacts caused by different MNEs behaviour especially with regard to the export intensity, while a greater impact on export decision is found when heterogeneity of local firms is accounted for.Exports, spillover, MNCs
