Small and medium-sized transnational corporations: Trends and patterns of foreign direct investment

This paper provides an analysis of small and medium-sized transnational corporations (TNCs). Statistical evidence is provided on trends and patterns of foreign direct investment (FDI) by small and medium-sized enterprises (SMEs). There are virtually no countries for which consistent and systematic FDI data are available by firm size, but data complied by or made available to the author for the UNCTAD Programme on Transnational Corporations allow an analysis of broad characteristics, trends and patterns.FDI by SMEs is more concentrated in developed countries than that by large TNCs. However, small and medium-sized TNCs, especially those from Japan, are increasingly investing in developing countries. Although absolute size of FDI is still small, SMEs account for a large share in terms of the number of investment cases and the number of parent firms. South and East Asia became the primary host region of small and medium-sized TNCs during the 1980s and early 1990s. The industrial distribution of FDI by SMEs in developing countries is quite wide, but concentrated in electrical goods, chemicals, textiles and some services industries. SMEs also engage in non-equity investments.Transnational Corporations Affairs Officer United Nations Conference on Trade and Development Geneva, SwitzerlandThe author is grateful for advice and comments by Hafiz Mirza     

Modeling Financial Integration,Intra-EMU and Asian-US External Imbalances

Intra-EMU external imbalances in the pre-crisis period up to 2008 are traditionally explained by EMU-oriented factors, e.g. euro-related financial integration. Chen et al. (2013) also emphasize external trade shocks, such as the competitive challenge of emerging Asia and oil exporters to EMU-periphery’s exports. Moreover, Asian-U.S. external imbalances are attributed to financial integration between East Asia and the USA in the aftermath of the East-Asian currency crises in the late 1990s (Angeletos and Panoussi 2011). Acknowledging these empirical facts this paper develops a Buiter (1981) three-country (EMU, Asia, US), two-region (EMU core, EMU periphery) OLG model to investigate the effects of both intra-EMU and Asian-U.S. financial integration on intra-EMU, Asian and U.S. external imbalances. We find that the widening of the intra-EMU external imbalances, in particular of trade imbalances, is related to the growth in Asian-U.S. imbalances and the dynamic inefficiency of the world economy, caused by excessive saving in Asia.     

Modeling heterogeneous effective advertising stock using single-source data

This paper presents a nonlinear modeling of market response between advertising stock and direct utility with heterogeneous parameters using single-source data. We examine advertising threshold effects and measure the effective advertising stock at the individual consumer level. Two kinds of information, i.e., TV advertising exposure data and consumer’s purchase history data, are combined for the modeling. The former is used for constructing advertising stock over calendar time via heterogeneous carryover parameters and the latter is applied to the choice model. The Markov chain Monte Carlo (MCMC) method is applied to estimate these heterogeneous parameters. Compared to other possible nonlinear specifications, it is shown that the proposed threshold utility function model with discontinuity at the threshold performs better than other smooth market response models. The empirical results support the existence of an advertising threshold and suggest the pulsing or “on/off” policy for our datasets. In terms of the effective reach, implying the reach after suspending the ad exposure to investigate how it is damping out for a possible “on/off” advertising policy, the optimal “off” interval was measured to be quite short to support a high-frequency pulsing policy, because the carryover parameter as well as the difference of ad stock and threshold are not large enough for our datasets.      

A brand choice model for TV advertising management using single-source data

A brand choice model for TV advertising management using single-source data is proposed. The model replaces household-specific advertising exposure, which is often used as a covariate in a brand choice model, with gross rating points (GRP), a managerial control variable for advertising. In particular, given daily GRP, a probabilistic model of advertising exposure for heterogeneous customers is integrated into a brand choice model with advertising threshold under a Bayesian framework. Through hierarchical modeling, demographic information on panels provides managerial insights into advertising planning.     

An Exploratory Examination of Service Quality Attributes in the Ecotourism Industry

This study explores service quality attributes of ecolodges in Australia. In-depth interviews were used to develop service quality dimensions that ecotourists believe to be of importance when visiting ecolodges. The performance-based measure of service quality (SERVPERF) was adapted as a generic measure of service quality in order to investigate whether the SERVPERF instrument is applicable to the ecolodge industry. Findings indicate that three additional dimensions are specific to the ecolodge sector: eco-friendly practices, eco-activities, and eco-learning. The findings are significant in assessing guests’ perceptions of service quality in the ecotourism area and can serve as a framework for further empirical research.
