Occupational Labour Demand and the Sources of Non‐neutral Technical Change*

This article introduces a two‐step empirical approach for examining both the nature and sources of non‐neutral technical change across multiple occupations. First, conventional labour‐demand parameter estimates and unbiased tests for neutrality are obtained in the context of a flexible cost system. The resulting input‐specific indices of technical change, unconstrained with respect to time path, facilitate subsequent evaluation of proposed sources. In our application to employment decisions of airline firms, we find labour‐saving technical change that is non‐neutral across occupations. We also document occupation‐specific responses to aircraft technology adoption, route system developments and an unprecedented range of technical change elements.

A stochastic differential game of capitalism

We develop a stochastic differential game of capitalism to analyze the role of uncertainty. In the deterministic game, the firm’s rent is completely taxed away and the firm stops investing completely. In the stochastic game, the government does not tax the firm’s rent completely. The firm posts a positive rate of investment if the firm’s rent exceeds the labor’s income. Although the cooperative solution is indeterminate, cooperation is always Pareto optimal compared to the non-cooperative Markovian Nash equilibrium. For individual rationality, we apply a payoff distribution procedure based on Yeung and Petrosyan (2006) to derive a subgame-consistent solution.     

Gauging potential sovereign risk contagion in Europe

This study adopts the CoVaR methodology to analyse the tail risk relationships among European sovereigns, which provide arguably important information for policymakers to identify countries that should come under close scrutiny during the current debt crisis.     

Unravelling of Dynamic Sorting

We consider a two-sided, finite-horizon search and matching model with heterogeneous types and complementarity between types. The quality of the pool of potential partners deteriorates as agents who have found mutually agreeable matches exit the market. When search is costless and all agents participate in each matching round, the market performs a sorting function in that high types of agents have multiple chances to match with their peers. However, this sorting function is lost if agents incur an arbitrarily small cost in order to participate in each round. With a sufficiently rich type space, the market unravels as almost all agents rush to participate in the first round and match and exit with anyone they meet.     

Approaches to the factory of the future. An empirical taxonomy

An empirical analysis of the patterns in which companies invest in advanced manufacturing technologies (AMTs) such as computer-aided design, computer-aided manufacturing, and flexible manufacturing systems is presented. Data for this analysis are gathered from 202 manufacturing plants chosen from industries generally considered to have relatively high investments in technology.Three general types of AMTs are identified from the literature: design, manufacturing, and administrative. Multiple item scales are developed to measure each type of AMT. These scales are shown to be reliable instruments, and are used to develop an empirical taxonomy which validates existing conceptual typologies of AMTs. A cluster analysis reveals four distinct groups of companies with respect to their approaches toward investing in AMTs. TRADITIONALISTS do not invest heavily in any of the three types of AMTs. GENERALISTS have moderate investments in each technology type. HIGH INVESTORS have the highest investment in each of the three technology types. The most interesting group may well be the DESIGNERS, which have low investments for manufacturing and administrative AMTs, but have the second highest investment in design-related AMTs.An analysis of the four technology groups reveals that while plants do differ in terms of plant size and integration, they do not differ significantly in terms of industry membership or performance. This suggests that successful firms can be found in each of the groups and that good strategies may be found that are consistent with each of these approaches. Therefore, the taxonomy is fairly robust, and further research must analyze companies within these groupings in order to identify the contingencies or other factors that may act in conjunction with technology to separate high and low performing firms. The data from our study clearly suggest that investments in technology alone are not a causal factor for performance improvement.     

The potential of anime for destination marketing: fantasies,otaku, and the kidult segment

While a substantial body of literature exists on film tourism, there is a lack of research attention bridging the potential of Japanese anime on real-world destination marketing. The implications of anime tourism can extend far beyond geographic boundary as the worldwide anime market is diversifying, providing novel opportunities for destination marketing organizations in other countries. To address this research gap, this paper first defines anime versus animated films to clarify the definition of anime for the tourism literature, and then draws out theoretical differences between the two types of entertainment within a cinematic perspective to highlight their conceptual boundaries across place, protagonist, and production. This paper suggests that the ways in which these three aspects are manifested in anime versus films are very different: anime settings are more fantasy-orientated than most films; viewers develop their self-identity (i.e. as an ‘otaku’) during childhood and adolescence; and anime productions can be extended with new series to create more enduring engagement to develop the kidult segment. This paper contributes to the literature by connecting the aforementioned cinematic aspects as a basis for elaboration of how differences among the three dimensions could be directly related to potential destination marketing activities.     

SEARCH EXTERNALITIES IN MACROECONOMIC THEORY

The paper gives a survey of the basic features of macroeconomic models with search externalities. It presents a simple static general equilibrium model with search externalities. Within this context the main results characterizing steady state in dynamic search models are reproduced in a simple context. Specifically, the link between transaction technology and strategic complementarity is analysed. It is shown that increasing returns to scale in the transaction technology create feed-back effects and multiple, Pareto-ranked equilibria may arise. With economies of scale in matching, fluctuations in the economy can be large even with a low elasticity of search activity. The formal equivalence to models with investment externalities is analysed. In an application to the labour market, the allocative role of wages in the presence of search frictions and hysteresis effects are discussed. General conditions are given under which the set of welfare ranked equilibria is described by a closed loop. Finally, it is shown that with a more general transaction technology, even with constant returns to scale multiple equilibria may occur in the presence of externalities.     

Endogenous Sequencing in Strategic Trade Policy Games Under Uncertainty

This paper examines a strategic trade policy game with endogenous timing. A trade-off between commitment and flexibility is identified. The equilibrium timing of trade policy decisions is shown to highly depend on the degree of demand uncertainty. When demand uncertainty is low, countervailing duties will never be used because the home government always sets its import tariff before the foreign government sets its export subsidy. When demand uncertainty reaches a threshold level, the home government starts to find it optimal to move second with positive probability. As a result, we provide an economic rationale for the prevailing use of countervailing duties in practice.     

The LeChatelier principle: the long and the short of it

Summary. Using ordinary calculus techniques, we investigate the conditions under which LeChatelier effects are signable for finite changes in parameter values. We show, for example, that the short run demand for a factor is always less responsive to price changes than the long run demand, provided that the factor of production and the fixed factor do not switch from being substitutes to being complements (or vice versa) over the relevant range of the price change. The absence of a sign change in the complementarity/substitutability relation holds under conditions that are considerably more general than supermodularity of the production function.
