The impact of the employee-organization relationship on temporary employees' performance and attitude: testing a Singaporean sample

Following the framework proposed by Tsui et al . (1997), this research paper examines the impact of the employee-organization relationship on temporary employees' job performance, turnover intention, overall job satisfaction, affective commitment, perception of fairness and perception of work options. Data were collected from 191 temporary employees from seven employment agencies in Singapore. Analyses conducted revealed that employee responses do vary under the four types of relationship (quasi-spot contract, under-investment, mutual investment and over-investment). In general, both mutual investment and over-investment relationships were associated with higher levels of performance and more favourable attitudes than either the under-investment or quasi-spot contract. Specifically, temporary employees under the mutual investment and over-investment relationships have better job performance, a higher level of affective commitment to the agency, improved overall job satisfaction, higher perception of fairness, higher perception of work options and lower turnover intentions. Furthermore, these finding were obtained even after controlling for the effects of company tenure and job level on employee performance and attitudes. The results highlight the importance of employee-organization relationships in eliciting the desired temporary employee outcomes. Practical implications were drawn for human resource practitioners and employment agencies on how best to manage temporary employees. Some limitations and suggestions for future research were discussed.     

Attracting the Rival’s Customers in a Model with Switching Costs

We consider the option of a firm’s honouring the rival’s coupons in a duopoly model in which products are differentiated by both characteristics and a switching cost. A firm may honour its rival’s coupons to increase its market share only if its previous market share is less than one‐half but not too low and, as a result, the market share is increased but only up to one‐half. JEL Classification Number: D13.     

Keyword auctions with budget-constrained bidders

We study a keyword auction model where bidders have constrained budgets. In the absence of budget constraints, Edelman et al. (Am Econ Rev 97(1):242–259, 2007) and Varian (Int J Ind Organ 25(6):1163–1178, 2007) analyze “locally envy-free equilibrium” or “symmetric Nash equilibrium” bidding strategies in generalized second-price auctions. However, bidders often have to set their daily budgets when they participate in an auction; once a bidder’s payment reaches his budget, he drops out of the auction. This raises an important strategic issue that has been overlooked in the previous literature: Bidders may change their bids to inflict higher prices on their competitors because under generalized second-price, the per-click price paid by a bidder is the next highest bid. We provide budget thresholds under which equilibria analyzed in Edelman et al. (Am Econ Rev 97(1):242–259, 2007) and Varian (Int J Ind Organ 25(6):1163–1178, 2007) are sustained as “equilibria with budget constraints” in our setting. We then consider a simple environment with one position and two bidders and show that a search engine’s revenue with budget constraints may be larger than its revenue without budget constraints.     

Jack of fewer trades: Evolution of specialization in research

It is widely maintained that scientists have become increasingly specialized with a narrow range of expertise ever since the era of “Renaissance men.” However, evidence on scientists' specialization is rather anecdotal. We provide large-scale evidence to address whether younger generations of inventors have indeed become more specialized, using a unique panel data set of Korean inventors. We also investigate how the degree of specialization evolves over an inventor's research career and how far an inventor switches his or her field of expertise in the technology space over a career.     

Competing at the frontier: The changing role of technology policy in Singapore's economic strategy

For an economy competing at the global frontier, an innovation-based growth strategy requires a well-developed technological infrastructure, a set of capabilities-focused technology policies, as well as an institutional environment that stimulates innovation and entrepreneurship. This paper examines the role played by science and technology policy in an economy's transition to an innovation-based growth strategy. We discuss the challenges governments face as they restructure economic institutions to deepen R&D capabilities and encourage technology creation. We review Singapore's experience in this regard and assess its ongoing efforts to remake itself to compete at the global frontier.     

Household Demand, Network Externality Effects and Intertemporal Price Discrimination

This paper examines the optimality of intertemporal price discrimination when network externality effects are present in the consumption of a durable good. We conduct our study in two settings. In a model with two household types, utilities are dependent on the cumulative proportion of households that have purchased the durable good. Next, in a model with a continuum of household types, we extend the analysis to the case where households consume both a durable good and a stream of non-durable goods. We show that in both settings, the presence of network externalities facilitates a sales strategy with intertemporal price discrimination.     

Analysis of the impact of agricultural R&D investment on food security

This article investigates how agricultural R&D investment affects the food self-sufficiency ratio (SSR). Several studies have argued a causal relationship between agricultural R&D investment and food security. However, most of these studies are based on conceptual logic and few studies have conducted an empirical analysis. This study verifies whether agricultural R&D investment affects the food SSR as a representative indicator of food security. A total of 822 data sets of 41 countries have been used in the analysis in this study and include developed and developing country data over the period 1981–2009. Food self-efficiency is used as a dependent variable, and agricultural R&D investment and other variables are used as explanatory variables. The estimation results show that, first, the cereal SSR and income are in an inverted U-shaped relationship. Second, increases in land productivity increase the cereal SSR and, lastly, the cereal SSR ratio and agricultural R&D investment are in a U-shaped relationship.
