An alternate approach to modeling the slack season provision of guided tours to tourists

We discuss an approach to modeling the slack season provision of guided tours to tourists that accounts for the twin phenomena of stochastic demand and tourist heterogeneity but is different from the way in which this problem has been modeled in the extant tourism literature. Our discussion uses the theory of discrete-time Markov chains and it models the slack season from a tourist demand perspective. Specifically, we first study a case in which the wait plus tour or the excursion time of an arriving tourist is exponentially distributed with a fixed mean. Next, we focus on a scenario in which the excursion time is exponentially distributed with one of two possible fixed means and these two means arise with specific probabilities.     

Facebook posting activity and the selective amplification of earnings disclosures

This study examines the determinants of Facebook activity levels with a particular focus on Facebook activity around earnings announcements. Facebook activity is generally higher for firms with higher levels of analyst following, individual ownership, and trading volume, indicating that it is responsive to investor demand effects. Facebook activity also increases around earnings announcements, with the increase being largely attributable to posts containing earnings news. In general, therefore, firms use Facebook posts to amplify earnings news. Such activity is selective, however; it is lower for firms with high levels of information asymmetry, for firms reporting earnings that exactly meet the consensus analyst forecast amount, and when the earnings news is negative but the accompanying price movement is positive. Hence, firms appear to use Facebook to manage the level of attention paid to earnings news.     

Banks’ equity performance and the term structure of interest rates

Using an extensive global sample, this paper investigates the impact of the term structure of interest rates on bank equity returns. Decomposing the yield curve to its three constituents (level, slope and curvature), the paper evaluates the time‐varying sensitivity of the bank's equity returns to these constituents by using a diagonal dynamic conditional correlation multivariate GARCH framework. Evidence reveals that the empirical proxies for the three factors explain the variations in equity returns above and beyond the market‐wide effect. More specifically, shocks to the long‐term (level) and short‐term (slope) factors have a statistically significant impact on equity returns, while those on the medium‐term (curvature) factor are less clear‐cut. Bank size plays an important role in the sense that exposures are higher for SIFIs and large banks compared to medium and small banks. Moreover, banks exhibit greater sensitivities to all risk factors during the crisis and post‐crisis periods compared to the pre‐crisis period; though these sensitivities do not differ for market‐oriented and bank‐oriented financial systems.     

The impact of climate change on labour demand in the plantation sector: the case of tea production in Sri Lanka

Limited opportunities for crop switching and lengthy preharvesting periods make the plantation sector particularly vulnerable to climate change. Surprisingly, however, the economic consequences of climate change on plantation crops are seldom analysed. Drawing on a unique primary panel data set from a representative cross section of 35 tea estates in Sri Lanka over the period 2002–2014, this study implements a structural model of estate profit maximisation to estimate the elasticity of labour demand with respect to different components of weather. Results indicate a negative relationship between labour demand and rainfall in the south‐west monsoon, the north‐east monsoon and the second inter‐monsoon. A positive relationship is found between labour demand and rainfall in the first inter‐monsoon. Overall, predicted changes in rainfall by 2050 are anticipated to reduce labour demand by approximately 1,175,000 person‐days per year across Sri Lanka's tea plantation sector. This is likely to have considerable social and welfare implications, particularly for the Indian Tamil women who comprise the majority of the sector's workforce.     

A Simple Two-Sector Model of Outsourcing

Outsourcing has become an increasingly contentious subject ever since N. Gregory Mankiw remarked in 2004 that outsourcing is just another way of doing international trade, and must be beneficial to the nation, including the workers. We construct a simple two-sector specific-factor model and explore the validity of Mankiw's remarks. We find his ideas are valid when the country does not produce any outsourced factor's work at home in that both the laborers and the nation benefit. But when some outsourced factor cum intermediate good is also produced at home, the nation still benefits but the workers may suffer.     

FOREIGN DIRECT INVESTMENT,NON‐TRADED GOODS AND REAL WAGES

Using a three‐sector general equilibrium model with non‐traded goods, we investigate the impact of foreign direct investment on the real wages of skilled and unskilled workers. We show that foreign direct investment increases the real wages of skilled and unskilled workers alike, but widens the gap between the two under plausible conditions.     

Leverage and growth: Effect of stock options

Previous literature documents a negative relationship between leverage and firm growth. This paper finds that once the incentives provided by stock options are accounted for, leverage does not affect firm growth. The paper also finds that the sensitivity of CEOs’ wealth to stock price (i.e. option delta) instead of leverage has a negative relationship with growth. These findings suggest that incentive contracts that tie managers’ wealth to firm value prevent managers from overinvesting. Thus in presence of options the role of debt as a disciplining mechanism has become less important.     

The design of an integrated group decision support system for technology assessment

Responding to the challenges of the marketplace compels firms to employ new production methods to improve product quality and delivery reliability, to reduce costs, and above all, to achieve greater flexibility. This paper outlines the system design of a group decision support system, developed to guide management through the process of new technology evaluation and adoption. The advantages of the proposed architecture include the opportunity to integrate a variety of independently developed components, the localisation of components (which leads to simplified maintenance) and the flexibility in the future for expanding and modifying the system.     

UNIFORM TECHNICAL PROGRESS: CAN IT BE HARMFUL?

Abstract.  In a model incorporating trade in final goods, intermediate goods and capital, we show how 'uniform' technical progress across sectors can lead to immiserization. The condition for immiserizing technical progress crucially depends on the pattern of specialization. Our results tend to hold in a more general specification of the basic structure.
