The double-hurdle and infrequency-of-purchase models are generalized with the inverse hyperbolic sine transformation in the dependent variable. The resulting specifications feature more flexible parameterization and error distributions than the untransformed models. Using the 1987–88 Nationwide Food Consumption Survey data on household pork consumption, a nonnested test suggests that the IHS double-hurdle model provides better characterization of the data-generating process than the IHS infrequency-of-purchase model but the elasticities derived from these models are similar. Own-price effects on the probability and level of consumption are negative and significant, but the elasticities are small. Income and cross-price effects are not significant. Household age composition, education, gender of meal planner, and race are among the demographic variables that affect consumption. 相似文献
Mobile telephony penetration is a major indicator of mobile telephony diffusion. Taiwan had a mobile telephony penetration of 108% in 2002, ranking first in the world. This study analyzes this accelerated diffusion in terms of growth model and determinants of the diffusion rate. To eliminate the inherent uncertainty associated with choosing the optimal growth model, this study compares the performance of three conventional models, namely Gompertz, Logistic and Bass, to identify the most appropriate model, and to distinguish the forces driving the diffusion rate. Empirical results indicate that the most appropriate model is the Logistic model. Network externalities, which this study shows to be the same as the imitation effect in the Bass model, explain the superiority of the Logistic model. Moreover, market competition, which markedly reduces service prices, is identified as a primary driver of the diffusion rate of mobile telephony in Taiwan. Economic conditions, technological innovation and number of operators are insignificant factors. Finally, mobile telephony is a substitute for fixed-line telephony in Taiwan. 相似文献
Does offshore production always result in job exportation? Using firm‐level data for Taiwanese multinationals that allow us to avoid reverse causality issues, this paper finds that while increasing offshore production has a negative impact on the demand for domestic manufacturing workers, this is not the case for domestic research and development workers who are often more skilled. The results also suggest that for Taiwan, there is geographical fragmentation of production activities in such a way that more skilled jobs are maintained domestically and less‐skilled jobs are exported to other developing countries. These findings confirm the prediction of the knowledge‐capital model. 相似文献
This study analyzes the macroeconomic impacts of subsidies to attract multinational corporations when firms are determining whether to enter or how to serve foreign markets. We show that a small FDI subsidy scheme induces consumption gains and delivers short‐term welfare improvement for the FDI host country if firms differ in productivity. However, the subsidy generates a new problem and results in the wealth reallocation effect, leading to welfare deterioration for the host country in the long run. Moreover, we find that a subsidy program induces a welfare improvement for the host country if it is offered to all domestic producers instead of foreign producers only in the host country. 相似文献
This paper examines the relationships amongst volatility, total trading volume (TVOL) and total open interest (TOI) for three Taiwan stock index futures markets as well as the role of the latter two variables in the dynamics of GARCH modeling and forecasting. From both ex-post and ex-ante perspectives, we study this issue by using the VAR model and augmented GARCH-type models, respectively. For the GARCH-type models, we employ both symmetric and asymmetric models augmented with lagged logs in TOI and/or TVOL. We find that whether addition of these two variables helps the basic GARCH models predict future volatility depends upon the sample period examined for all three sets of futures. Nonetheless, the best three models for out-of-sample volatility forecasting in the MSE sense are generally the augmented models for all sub-intervals and all three futures contracts. 相似文献
Purpose: Interfirm knowledge sharing has been well recognized to activate the performance and competitiveness improvement of the firms. Previous research has discussed the impacts of current suppliers on buyer–supplier knowledge sharing, but does not explain how this influence occurs. This study aims to disclose the mechanism by which both current and competing suppliers impact buyer–supplier knowledge sharing in buyers’ new product development activities.
Methodology/approach: This study proposed a conceptual model based on relational exchange theory and developed eight hypotheses. Questionnaire survey was used to collect empirical data from R&D staff of Taiwanese electronics firms. This study distributed 1,475 questionnaires and received 246 eligible questionnaires. Structural equation modeling was used to test and verify appropriateness of the proposed model.
Findings: The findings show that current supplier asset specificity positively and directly influences buyer–supplier knowledge sharing in new product development. The current supplier asset specificity also has indirect positive influence on buyer–supplier knowledge sharing in new product development via the mediating effects of buyer trust, satisfaction, and commitment. However, the attractiveness of alternative suppliers only indirectly and negatively affects buyer–supplier knowledge sharing via the mediating effects of buyer trust, satisfaction, and commitment.
Research limitations/implications: This study surveyed the firms in Taiwanese electronics industry. Nevertheless, new product development activities are executed by electronics firms in numerous countries and firms in various industries. For validating the generalization of this study’s results, future research can investigate firms in other industries and countries to verify the proposed model and hypotheses.
Practical implications: Current suppliers’ asset specificity is found to exert more influence on buyer–supplier knowledge sharing than alternative attractiveness. The findings imply that current suppliers should focus on investing specific assets for buyers other than stress the attractiveness and threat of competing suppliers.
Originality/value/contribution: This study initiates to approach the antecedents and influence mechanism of current buyer–supplier knowledge sharing via both perspectives of current and competing suppliers. 相似文献
