Flexible Contracts and Human Capital Investments

As suggested by human capital theory, workers with flexible contracts participate less often in training than those with permanent contracts. We find that this is merely due to the fact that flexworkers receive less employer-funded training, a gap they can only partly compensate for by their own training investments. Flexworkers particularly participate less in firm-specific training that is meant to keep up with new skill demands than workers with permanent contracts. However, for those who participate in employer-funded firm-specific training, a temporary contract appears to facilitate the transition to a permanent contract with the same employer. However, this does not hold for participation in self-paid training. This training, which is usually general training, does not help in finding a better job.     

Consumer satisfaction and loyalty: Two main consequences of retailer personality

This article investigates the impact of retailer personality on consumers' satisfaction with and loyalty to the retailer, measured through attitude and future behavioral intentions. Data were collected on a convenience sample of 372 customers of a specific retailer. Using partial least squares analysis (PLS), we show that four traits (“congeniality”, “originality”, “conscientiousness” and “preciousness”) have a direct or indirect impact on one of the dependent variables studied. Hence, this article proposes a model of the consequences of retailer personality and suggests that retailer personality is an important concept that practitioners should consider when running their satisfaction and loyalty programs.     

Municipal support of wireless access network rollout: A game theoretic approach

Next generation access networks are expected to bring ubiquitous broadband access and have attracted interest of municipal governments. This paper investigates the support by municipal authorities for the rollout of such a city-wide wireless broadband access network. Different business cases for 3G and WiFi operators are developed and it is indicated how to model the specificities for commercial versus public players. Furthermore, a game theoretic approach is used to investigate the investment options of the municipal player. It is shown that a partnership between a commercial and public player is the most likely investment strategy. However, bringing more players into the competitive environment reduces the intention of the commercial partner to engage in the public–private partnership (PPP).     

Tying the politicians’ hands: The optimal limits to representative democracy

The citizen candidate models of democracy assume that politicians have their own preferences that are not fully revealed at the time of elections. We study the optimal delegation problem which arises between the median voter (the writer of the constitution) and the (future) incumbent politician under the assumption that not only the state of the world but also the politician's type (preferred policy) are the policy‐maker's private information. We show that it is optimal to tie the hands of the politician by imposing both a policy floor and a policy cap and delegating him/her the policy choice only in between the cap and the floor. The delegation interval is shown to be the smaller the greater is the uncertainty about the politician's type. These results are also applicable to settings outside the specific problem that our model addresses.

Anticipating critical transitions of the housing market: new evidence from China

We introduce a novel quantitative methodology to detect real estate bubbles and forecast their critical end time, which we apply to the housing markets of China's metropolises. Building on the Log-Periodic Power Law Singularity (LPPLS) model of self-reinforcing feedback loops, we use the quantile regression calibration approach recently introduced by two of us to build confidence intervals and explore possible distinct scenarios. We propose to consolidate the quantile regressions into the arithmetic average of the quantile-based LPPLS Confidence indicator, which accounts for the robustness of the calibration with respect to bootstrapped residuals. We make three main contributions to the literature of real estate bubbles. First, we verify the validity of the arithmetic average of the quantile-based LPPLS Confidence indicator by studying the critical times of historical housing price bubbles in the U.S., Hong Kong, U.K. and Canada. Second, the LPPLS detection methods are applied to provide early warning signals of the housing markets in some metropolises in China. Third, we determine the possible turning points of the markets in Beijing, Shanghai, Shenzhen, Guangzhou, Tianjin and Chengdu and anticipate critical transitions of China's housing markets via our multi-scales and multi-quantiles analyses. Finally, given these projections performed in February 2017, the price trajectories from March 2017 to January 2018 that became available from the time of submission to the time of revision of the present article offer quite unique genuine out-of-sample tests of the performances of our indicators.     

A Structural Analysis of Credit Risk With Risky Collateral: A Methodology for Haircut Determination

Although many credit risk pricing models exist in the academic literature, very little attention has been paid to the impact of risky collateral on credit risk. It is nonetheless well known that practitioners often mitigate credit risk with collateral, using so–called haircuts for collateral level determination. The presence of collateral has a complex effect that can not be analysed simply with existing models. We analyse the value of credit risk when there is collateral in a range of different situations, including dual–default in a simple setting, stochastic collateral, stochastic bond collateral with stochastic interest rates, continuous and discrete marking–to–market and margin calls. The models confirm many practical intuitions, such as the impact on the haircut level required of the risks of the collateral asset and of the underlying asset to the forward as well as the impact of their correlation. Moreover, the model supports the intuition that the frequency of marking–to–market and collateral are substitutes. The models also stress the possibly unexpected magnitude of these factors. More importantly, they give actual solutions to determining the value of the credit risk depending on the haircut chosen and the frequency of marking–to–markets, results not presented before in the literature. The models are also a good basis to understand the portfolio effect of collateral management. Finally, they illustrate how differences in prices may arise from pure differences of credit risk management, as illustrated here in the case of futures and forwards.

Increasing returns,entrepreneurship and imperfect competition

We study a simple bilateral oligopoly model in which individual agents, who are initially endowed with capital, decide sequentially (1) whether they want to act as producers (entrepreneurs) or as capital lenders (rentiers) and, then (2) which quantity of capital they would like to borrow or lend, though exchange of capital units against units of the produced good. Production takes place under increasing returns to scale. We show the existence of “natural equilibria”, at which wealthier capital owners become entrepreneurs while the remaining ones decide to be rentiers. We also study the efficiency of equilibria which is shown to increase by replication of the economy, but sometimes to decrease as a consequence of wealth redistribution.We thank an anonymous referee for his insightful comments     

The Exchange Rate Macroeconomic Balance Approach: New Methodology and Results for the Euro,the Dollar,the Yen and the Pound Sterling

This paper presents an extension of the macroeconomic exchange rate balance approach. This extension comprises two new aspects. Firstly, it is based on a multinational framework which allows for macroeconomic linkages between countries. Secondly, it uses a procedure that does not require a full modeling of the world economy to derive a consistent set of equilibrium exchange rates. The findings reveal that, in 2001, the dollar was overvalued against the euro and the yen. The paper also shows that this result depends heavily on the chosen notion of current account sustainability.
