In this paper we consider three questions. Why do only some firms enter export markets? What are the benefits to the firm from export market entry? Why do some of these firms exit the market at a future date? Using data on UK manufacturing firms from 1988 to 2002 we find evidence that information spillovers between firms can raise the probability of entry and for a matched sample of firms there...

This paper extends Symeonidis (2003)’s duopoly model with product differentiation to discusses how FDI spillovers that decreases the quality difference between vertically differentiated products of the home and foreign firms affects the home firm’s decision on plant location. This paper shows that whether the degree of spillover is exogenous or endogenous, it may have a positive relationship wi...

Under plausible assumptions about preferences and technology, the model in this paper suggests that the entire volume of world trade matters for wage inequality. Therefore, trade integration, even among identical countries, is likely to increase the skill premium. Further, we argue that empirical evidence of a falling relative price of skill-intensive goods can be reconciled with the fast growt...

To analyze the effects on prices of simultaneous tariff reductions by multiple importing countries, we construct a simple three-country model where a good is produced by a monopolist with non-constant marginal cost and imported by two countries. We specifically compare two representative tariff-reduction formulas: the "fixed-amount" and the "uniform percentage" reductions. The uniform percentag...

objective: worldwide, diabetes mellitus (dm) is an ever-increasing metabolic disorder. a promising approach to the treatment of dm is the implantation of insulin producing cells (ipc) that have been derived from various stem cells. culture conditions play a pivotal role in the quality and quantity of the differentiated cells. in this experimental study, we have applied various culture condition...

The maize b-70 protein is an endoplasmic reticulum protein overproduced in the floury-2 (f12) endosperm mutant. The increase in b-70 levels in f12 plants occurs during seed maturation and is endosperm specific. We have used amino acid sequence homology to identify b-70 as a homolog of mammalian immunoglobulin binding protein (BiP). Purified b-70 fractions contain two 75-kilodalton polypeptides ...

In this paper, several two-dimensional extensions of principal component analysis (PCA) and linear discriminant analysis (LDA) techniques has been applied in a lossless dimensionality reduction framework, for face recognition application. In this framework, the benefits of dimensionality reduction were used to improve the performance of its predictive model, which was a support vector machine (...

The fundamental vibrational frequency of the B–N stretch in BH3NH3 has eluded gas-phase experimental observation for decades. This work offers a theoretical anharmonic prediction this mode to be 644 cm−1, using Cartesian quartic force field at CCSD(T)-F12/cc-pVTZ-F12 level theory. other frequencies reported herein have mean absolute error only 5 cm−1 from seven available frequencies, making and...

We construct a model of trade with heterogeneous retailers to examine the effects of trade liberalization on retail market structure, imports and social welfare. We are especially interested in investigating the transmission of lower import prices into consumer prices and the effects of retail market regulation. The paper shows that changes in import prices may have large effects on consumer pr...

Fuzzy rule-based classification system (FRBCS) is a popular machine learning technique for classification purposes. One of the major issues when applying it on imbalanced data sets is its biased to the majority class, such that, it performs poorly in respect to the minority class. However many cases the minority classes are more important than the majority ones. In this paper, we have extended ...
