Codetermination,Price Competition and the Network Industry

This research develops a tractable two‐stage non‐cooperative game with complete information describing the behaviour of price‐setting firms that must choose to be profit maximisers or bargainers under codetermination in a network industry with horizontal product differentiation. The existing theoretical literature has already shown that codetermination might arise as the endogenous market outcome in a strategic competitive quantity‐setting duopoly. In sharp contrast with this result, the present article shows that codetermination does never emerge as a Nash equilibrium in a price‐setting non‐network duopoly. Then, it aims at highlighting the role of network externalities in determining changes of paradigm of the game and letting codetermination become a sub‐game perfect Nash equilibrium when prices are strategic substitutes or strategic complements. This equilibrium may be Pareto efficient. Results allow distinguishing between mandatory codetermination and voluntary codetermination. The article also proposes a model of endogenous codetermination according to which every firm may choose to bargain with its own corresponding union bargaining unit only whether the firm's bargaining strength is exactly the profit‐maximising one. The equilibrium outcomes emerging in this case range from a uniform Nash equilibrium, in which both firms are codetermined, to mixed Nash equilibria, in which only one of them chooses to be codetermined. These results are ‘network depending’ and do not hold in a non‐network duopoly.     

High exchange-rate volatility and low pass-through

Two specifications of an open-economy model are shown to generate high exchange-rate volatility and low exchange-rate pass-through (ERPT). In the model, price discrimination causes ERPT to be incomplete in both the short and the long run. In the short run, a small amount of nominal rigidities is enough to reduce ERPT sharply; still, exchange-rate depreciation worsens the terms of trade, consistent with the evidence. Possible biases from omitted variables and measurement error in the ERPT empirical literature (due to data limitations) are investigated using model-generated time series. Estimates of ERPT coefficients can be quite different from true parameters, and are sensitive to the shocks driving the economies. Estimates can nonetheless detect key structural features of the models.     

The pricing effect of certification on syndicated loans

To verify if a delegated monitor can certify its ability to perform its assigned tasks, we test whether syndicated loans in which a larger share of the facility is retained by the arranger have lower interest rates. For a large sample of syndicated loans in over 80 countries we find that this certification effect exists and is greater for facilities characterized by greater due diligence and monitoring efforts. Further, for listed companies the announcement effect of the new loan on the stock price is an increasing function of the portions of the loan retained by the arranger.     

A tale of minorities: evidence on religious ethics and entrepreneurship

Does Protestantism favour entrepreneurship more than Catholicism does? We provide a novel way to answer this question by comparing Protestant and Catholic minorities using Swiss census data. Exploiting the strong adhesion of religious minorities to their denomination’ ethical principles and the historical determination of the geographical distribution of denominations across Swiss cantons, we find that Protestantism is associated with a significantly higher propensity for entrepreneurship. The estimated difference ranges between 1.5 and 3.2 % points, it is larger the smaller the size of the religious minority, it is mainly driven by prime age male entrepreneurs and it stands up to a number of robustness checks. No effects are found when comparing religious majorities, suggesting that the implications of religious ethical norms on economic outcomes emerge only when such norms are fully internalized.     

US stock returns: are there seasons of excesses?

This article explores the existence of seasonality in the tails of stock returns. We use a parametric model to describe the returns, and obtain a proxy of the innovation distribution via a pre-processing model. Then, we develop a change-point algorithm capturing changes in the tails of the innovations. We confirm the good performance of the procedure through extensive Monte Carlo experiments. An empirical investigation using US stocks data shows that while the lower tail of the innovations is approximately constant over the year, the upper tail is larger in Winter than in Summer, in 9 out of 12 industries.

基于省域面板数据模型的金融集聚影响因素研究

利用联合面板数据模型,从金融集聚驱动机制角度出发,实证研究表明:信息不对称、规模经济和政府政策对金融集聚都具有显著性影响,其中信息自由流动和规模经济对金融集聚影响效应远高于政府政策效应,从而表明我国金融集聚程度提高转向依靠市场力量来驱动。其中,东部地区对信息不对称的依赖程度较大,中部地区金融集聚程度主要依靠政府政策来驱动,而西部地区由于经济基础落后,受信息不对称影响较大。     

Media effects on sustainable food consumption. How newspaper coverage relates to supermarket expenditures

Information provision is often considered to have an important role to play in changing consumers' choices. However, there is still no consensus on the mechanisms by which information might influence specific consumer expenditures, especially in relation to environmentally friendly food products. This paper explores whether the public debate on sustainable consumption in UK broadsheets and tabloids relates to observed consumers' expenditures. It does so by relating the number of published articles on selected sustainability topics to consumers' food expenditure in a leading UK supermarket from May 2009 to May 2011, using regression analysis. We selected only regular supermarket's shoppers who frequently buy the Sunday editions of the analyzed newspapers. Results indicate very sparse and inconsistent correlations suggesting that the impact of information is only minimally effective. The number of newspaper articles relates mainly to expenditures on organic, wholegrain and low salt products, possibly indicating a preference for healthy food. No consistent effects are observed when media target a change in more general food categories (e.g. a reduction in food of animal origin), although we observed some influence on purchases of fish. Finally, results indicate some correlations with purchases of meat for the readers of the Telegraph. In order to contextualize some of the results, we applied content analysis to a subsample of published articles on organic food. The qualitative approach shows that the framing of the news is important: change is positively related to information proposed uncritically; and negatively to information contextualized as a highly structured debate.
