Trade,Technology and the Labour Market: The Case of South Africa*

This study advances previous work on the effects of trade and technological change on labour markets within the framework of Heckscher–Ohlin trade theory. We provide evidence for an unskilled labour abundant developing country by employing dynamic heterogeneous panel estimation techniques. For South African manufacturing, trade‐mandated increases in earnings are positive for labour and negative for capital whilst technology‐mandated increases are negative for both factors. We also find it important to take account of endogeneity issues in analysing the impact of technology and price changes on factor returns and in isolating factor‐ and sector‐bias of technological changes.     

Labor market structure and offshoring

We consider a two‐country, two‐sector model in which a firm’s offshoring decision depends on labor market rigidities that impose additional costs on the firm. Firms endogenously choose their organizational form considering their productivity level and organizational costs. The costs generated by labor market frictions play a key role in determining the benefits of each organizational structure, and thus helps determine the conditions under which a firm decides to offshore. There are three different types of equilibria depending on the relative levels of the domestic and foreign labor market costs and the price of the intermediate input. In all equilibria, a relative rise in the domestic labor market cost increases the share of firms that offshore, while decreasing domestic integration. Furthermore, an economy with offshoring has a higher welfare level and a lower unemployment rate than it would under autarky.     

Climate impacts on geographical changes in the energy industry

Owing to global warming, ice in the Arctic Ocean has shrunk by 2.7% every 10 years since 1978, resulting in tremendous damage. This study uses the Cobb–Douglas production function to analyze the impact of abnormal weather on energy industry production using temperature and precipitation indicators. In particular, the government identified the impact of abnormal weather conditions on manufacturing and public works related to the Korean energy industry. The results showed that the numbers of freezing days and heavy rain days adversely affect public works, whereas hot and cold days and heavy rain days all positively affect the production of coal, petroleum, and chemical products. These results also led to regional risk assessments of the energy industry. This study can help in developing the 2030 industry climate change adaptation plan.     

Which Is the Better Option? Quicker or Cheaper?

Both time and money are valuable scarce resources, but their different characteristics lead to different perceived value in saving time and saving money. The perishability and fixed supply associated with time may enhance its value; however, its inherent nature, difficulty accounting for value of time, infungibility, and perceived slack may weaken its value. Drawing on theories and findings in the domains of temporal and monetary judgment, this research study posits that people usually underappreciate the value of time because the information pertinent to the value of time is less accessible in peoples’ memory compared with monetary value. Hence, prompting people regarding the value of time and the value of money could make their preference for saving time similar to that of saving money. Additionally, people typically expect more time slack than money in the future, thereby discounting their preference for saving time faster than for saving money. The results of a series of experiments support these hypotheses.     

Aggregation and the Endogeneity Problem

This paper investigates the combined effects of the aggregation and endogeneity problems when there exists a correlation between explanatory variables and the error term in the micro equation. Comparing OLS estimates on the basis of an asymptotic-square-bias criterion, the analysis indicates that aggregate equations are in general subject to less endogeneity due to the synchronization effect. The trade-off between aggregation and endogeneity biases is examined and the conditions under which the aggregate equation is superior to the micro equation are derived in terms of the relative sizes of parameters.

Time series analysis for financial market meltdowns

There appears to be a consensus that the recent instability in global financial markets may be attributable in part to the failure of financial modeling. More specifically, it is alleged that current risk models have failed to properly assess the risks associated with large adverse stock price behavior. In this paper, we first discuss the limitations of classical time series models for forecasting financial market meltdowns. Then we set forth a framework capable of forecasting both extreme events and highly volatile markets. Based on the empirical evidence presented in this paper, our framework offers an improvement over prevailing models for evaluating stock market risk exposure during distressed market periods.     

What makes consumers use VoIP over mobile phones? Free riding or consumerization of new service

Consumer acceptance of technological innovations is crucial to marketing strategy and policy development. This study analyzes consumer behaviors in mobile voice over Internet protocol (mVoIP), focusing on the antecedents of consumers' intentions. Using a context-specific extension of the Technology Acceptance Model, mVoIP acceptance was investigated based on the salient belief of perceived usefulness, perceived ease of use, and facilitating factors. The results show that quality factors of mVoIP significantly influence the usefulness and ease of use, which subsequently affect the adoption of the technology. Call and service quality were found to be significant factors, followed by mobility and coverage. The policy and managerial implications of mVoIP are discussed based on the model. In conclusion, this study provides in-depth analysis and heuristic data on the consumer drivers, market dynamics, and policy implication within the mVoIP ecosystem.     

Business groups and corporate transparency in emerging markets: Empirical evidence from India

This study examines the difference in corporate transparency of firms affiliated with business groups and unaffiliated firms in India. Based on previous studies we measured corporate transparency using equity analysts’ forecast error and dispersion. We find that firms affiliated with business groups are less transparent than unaffiliated firms. Lack of transparency leads to higher analyst forecast error and dispersion. This study also finds that business group-affiliated firms with more intra-group capital transactions have higher forecast error and dispersion. The findings of this study suggest that firms affiliated with business groups are less transparent due to their reliance on internal capital markets, and therefore lack incentives to disclose information to market participants. As a result, the information asymmetry between business groups and the capital market is higher, restricting the activities of information intermediaries such as equity analysts, who play an important role in the external capital market.     

The influence of regulations on the efficiency of telecommunications operators: A meta-frontier analysis

The telecommunications industry has a great ripple effect on the overall national economy. However, there is no consensus about what is the optimal regulation policy for the telecommunications industry. Regulations on the telecommunications industry are different by region (i.e. United States, European Union and Asia). A number of studies have been conducted on comparative efficiency analysis for different policies that apply stochastic frontier analysis or data envelope analysis. However, these comparative studies are inappropriate because the production functions for each region are not identical. Thus, this paper addresses meta-frontier methodology, which can reflect differences in production functions. The results indicate that the United States has the highest meta-frontier efficiency in contrast to previous research findings.     

Well-intended policies

Market failures provide a rationale for policy intervention. But policies are often hard to alter once in place. We argue that this inertia can result in well-intended policies having sizable negative long-run effects on aggregate output and productivity. In our theory, financial frictions provide a rationale for providing subsidized credit to productive entrepreneurs to alleviate the credit constraints they face. In the short run, such targeted subsidies have the intended effect and raise aggregate output and productivity. In the long run, however, individual productivities mean-revert while individual-specific subsidies remain fixed. As a result, entry into entrepreneurship is distorted: The subsidies prop up entrepreneurs that were formerly productive but are now unproductive, while impeding the entry of newly productive individuals. Therefore aggregate output and productivity are depressed. Our theory provides an explanation for two empirical observations on developing countries: idiosyncratic distortions that disproportionately affect productive establishments, and temporary growth miracles followed by growth failures.
