Assessing the Behaviour of Non-Survey Methods for Constructing Regional Input–Output Tables through a Monte Carlo Simulation

The paper aims to analyse the behaviour of a battery of non-survey techniques of constructing regional I-O tables in estimating impact. For this aim, a Monte Carlo simulation, based on the generation of ‘true’ multiregional I-O tables, was carried out. By aggregating multi-regional I-O tables, national I-O tables were obtained. From the latter, indirect regional tables were derived through the application of various regionalisation methods and the relevant multipliers were compared with the ‘true’ multipliers using a set of statistics. Three aspects of the behaviour of the methods have been analysed: performances to reproduce ‘true’ multipliers, variability of simulation error and direction of bias. The results have demonstrated that the Flegg et al. Location Quotient (FLQ) and its augmented version (AFLQ) represent an effective improvement of conventional techniques based on the use of location quotients in both reproducing ‘true’ multipliers and generating more stable simulation errors. In addition, the results have confirmed the existence of a tendency of the methods to over/underestimate impact. In the cases of the FLQ and the AFLQ, this tendency depends on the value of the parameter δ.     

Is M&A different during a crisis? Evidence from the European banking sector

The financial crisis has affected the landscape of the banking sector around the world. We use a sample of transactions carried out by European acquirers in 2007–2010 to study the acquirer’s stock price market reaction to both announcements and completions of acquisitions. At the aggregate level, we find that there are no significant abnormal returns around the announcement of an acquisition while there are positive abnormal returns at completions. We study the cross-sectional determinants of abnormal returns and find that announcement returns are mainly explained by the acquirer bank characteristics, while completion returns mainly depend on opacity of the target and on the drop in idiosyncratic volatility associated with a reduction of uncertainty.     

Have Standard VARS Remained Stable Since the Crisis?

Small vector autoregressions are commonly used in macroeconomics for forecasting and evaluating shock transmission. This requires VAR parameters to be stable over the evaluation and forecast sample or modeled as time‐varying. Prior work has considered whether there were sizable parameter changes in the early 1980s and in the subsequent period until the beginning of the new century. This paper conducts a similar analysis focused on the period since the recent crisis. Using a range of techniques, we provide substantial evidence against parameter stability. The evolution of the unemployment rate seems particularly different relative to its past behavior. We also evaluate alternative methods to handle parameter instability in a forecasting context.

Microeconomic mechanisms behind export spillovers from FDI: evidence from Bulgaria

This paper studies how the presence of multinational enterprises affects the export performance of Bulgarian manufacturing firms—export spillovers from FDI. Using export data at the firm/product/destination level for the period 2004–2006, it finds positive forward spillover on export value and quantity, related to quality upgrading. Conversely, it finds negative (or insignificant) backward and horizontal spillover on export flows, related to quality downgrading. When aggregating data at the firm level and considering that a firm can operate in several sectors, the paper shows that the presence of foreign input suppliers allows domestic firms to export additional varieties of lower quality and upgrade the average quality of existing varieties, whereas the presence of foreign customers generates the opposite effect.     

Barriers to entry, deregulation and workplace training: A theoretical model with evidence from Europe

We study the impact of regulatory barriers to entry on workplace training. We develop a model of training in imperfectly competitive product and labour markets. The model indicates that there are two contrasting effects of deregulation on training. As stressed in the literature, with a given number of firms, deregulation reduces the size of rents per unit of output that firms can reap by training their employees. Yet, the number of firms increases following deregulation, thereby raising output and profit gains from training and improving investment incentives. The latter effect prevails. In line with the predictions of the theoretical model, we find that the substantial deregulation in the 1990s of heavily regulated European industries (energy, transport and communication) increased training incidence.     

Food miles: Do UK consumers actually care?

The food miles concept, originating in the UK and given much prominence in the news media, has been used to imply that importing food from distant countries is inherently more wasteful than growing and consuming local produce. What impact is this potential non-tariff barrier having on consumer buying behaviour in UK supermarkets? Revealed preference surveys in four supermarkets show only 5.6% of 251 consumers nominated country-of-origin as one of the reasons for choosing a fresh food item they had just purchased. Furthermore, only 3.6% indicated that they had consciously chosen British products for the reason that such produce was “less harmful for the environment.” In contrast, stated preference surveys in the street found that 21.5% indicated that “food miles” or “the long distance it travels” would stop them buying New Zealand products. What people say may differ substantially from what they actually do in regard to “food miles.”
