Fiscal Policy in Europe: How Effective Are Automatic Stabilisers?

It is largely recognised that fiscal policy will have largerresponsibilities for cyclicalstabilisation in EMU given the loss of the monetary instrument.At the same time, theEMU's budgetary framework emphasises the need to rely onautomatic fiscal stabilisers,rather than active policies in cushioning the business cycle.We show that automaticstabilisers are relatively powerful in the event of shocksto private consumption, but lessso in the case of shocks to private investment and exports.In the case of supply sideshocks, the automatic stabilisers are largely ineffective,but this may actually be a goodthing to the extent that supply-side disturbances call forstructural adjustment rather thancyclical stabilisation.     

Entry deterrence and innovation in durable-goods monopoly

This paper investigates the efficiency of innovation investments in a durable-goods monopoly when a potential entrant threatens to innovate as well. We show that the durability of the good endows the monopolist with the power to discourage rival innovation since current sales alter the demand for a new generation of the good. The equilibrium is therefore determined not only by the incentive for intertemporal price discrimination in durable-goods monopoly, but also by the incumbent's concern for maintaining the technological leadership. We demonstrate that entry deterrence followed by no innovation always implies underinvestment in innovation.     

Loss-leader pricing and upgrades

A new theory of loss-leader pricing is provided in which firms advertise low (below cost) prices for certain goods to signal that their other unadvertised (substitute) goods are not priced too high. The theory is applied to the pricing of upgrades. The results contrast with most existing loss-leader theories in that firms make a loss on some consumers (who buy the basic version of the good) and a profit on others (who buy the upgrade).     

IMMIGRANT RELATIVE WAGES AT THE GREAT RECESSION: EVIDENCE WITH MATCHED EMPLOYER‐EMPLOYEE DATA FOR SPAIN

The article examines relative wages of immigrants in Spain, with a particular focus on the impact of the Great Recession. The empirical analysis is restricted to men and is based on matched employer‐employee microdata and the decomposition techniques of Juhn et al. (1991, 1993) and Fortin et al. (2011). Our results show that the significant native‐immigrant wage gap that exists both in terms of average wages and of differentials along the wage distribution is essentially explained by differences in the endowments of observed characteristics so that, in general, immigrants tend to receive a similar wage treatment than Spaniards with analogous observed attributes. On the other hand, the Great Recession has had a noticeable impact on the relative wages of immigrants, given that the significant increase of the native‐immigrant wage gap observed during the previous expansionary period was mitigated during the economic downturn due to composition effects arising from the severe employment destruction pattern.     

The impact of the global financial crisis on the cross-currency linkage of LIBOR–OIS spreads

This article examines the impact of global financial crisis on cross-currency linkage of the LIBOR–OIS spread, a financial stress measure in interbank markets. The impulse response analysis is conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. The overall evidence suggests that the crisis has substantially changed the nature of the cross-currency interactions in liquidity stress. Also global money markets have failed to contain stress in US dollar funding and the role of the Japanese yen as a liquidity source appears to be significant, while these two currencies drive the cross-currency system of liquidity stress.     

The role of stochastic volatility and return jumps: reproducing volatility and higher moments in the KOSPI 200 returns dynamics

This paper investigates the role of stochastic volatility and return jumps in reproducing the volatility dynamics and the shape characteristics of the Korean Composite Stock Price Index (KOSPI) 200 returns distribution. Using efficient method of moments and reprojection analysis, we find that stochastic volatility models, both with and without return jumps, capture return dynamics surprisingly well. The stochastic volatility model without return jumps, however, cannot fully reproduce the conditional kurtosis implied by the data. Return jumps successfully complement this gap. We also find that return jumps are essential in capturing the volatility smirk effects observed in short-term options.

Where to vacation? An agent-based approach to modelling tourist decision-making process

Agent-based models (ABMs) are becoming more relevant in social simulation due to the potential to model complex phenomena that emerge from individual interactions. In tourism research, complexity is a subject of growing interest and researchers start to analyse the tourism system as a complex phenomenon. However, there is little application of ABMs as a tool to explore and predict tourism patterns. The purpose of the paper is to develop an ABM that increases knowledge in tourism research by (i) considering the complexity of tourism phenomenon, (ii) providing tools to explore the complex relations between system components and (iii) giving insights on the functioning of the system and the tourist decision-making process. A theoretical ABM is developed to improve knowledge on tourist decision-making in the selection of a destination to vacation. Tourists’ behaviour, such as individual motivation, and social network influence in the vacation decision-making process are hereby discussed.     

A Theory of Economic Obsolescence

A new generation of durable goods makes an old generation economically, even if not physically, obsolete. Economic obsolescence due to technological innovation requires the durable goods monopolist to implement price discrimination in two dimensions, both between consumers with different valuations and between consumers with different purchase histories. Equilibrium in the game between the durable goods monopolist and consumers depends on the extent of economic obsolescence and the relative sizes of the consumer groups. Underinvestment in innovation may take place. This contrasts with the standard literature on planned obsolescence where the durable goods monopolist overinvests in durability reducing technology.
