IDENTIFICATION AND ESTIMATION OF AUCTION MODEL WITH TWO‐DIMENSIONAL UNOBSERVED HETEROGENEITY*

This article investigates the empirical importance of allowing for multidimensional sources of unobserved heterogeneity in auction models with private information. It develops the estimation procedure to recover the distribution of private information in the presence of two sources of unobserved heterogeneity. It is shown that this estimation procedure identifies components of the model and produces uniformly consistent estimators of these components. The results of the estimation with highway procurement data indicate that allowing for two‐dimensional unobserved heterogeneity may significantly affect the results of estimation as well as policy‐relevant instruments derived from the estimated distributions of bidders’ costs.     

Relative Price Changes and Households' Welfare in Italy

The entrance of Italy in the Euro area in 2001 has given rise to a wide debate about the perception of inflation on households' well‐being. However, most of the debate has involved the measurement of the “correct” consumer price index at the national level. Much less analysis has been carried out on the distributional consequences of inflation on every household. The paper addresses this issue by performing a microsimulation analysis of the impact of inflation on Italian households in the period 1997–2007. It is shown that the impact of inflation has an ambiguous path over the period, with a large concentration of welfare losses around the introduction of the Euro currency. In particular, it is found that poorer and larger households are severely hurt by inflation and that the prices of gas and gasoline are largely responsible for determining the living conditions of Italian households.     

The Effect of R&D Services Offshoring on Skilled Employment: Firm Evidence

The offshoring of high‐tech services has greatly increased in recent years, with consequences for firms demand for skilled employment in firms. This paper specifically analyses the relationship between R&D offshoring and the demand for R&D employment using firm‐level data for Spanish manufacturing and services companies during the period 2004–11. Estimating different specifications with panel data techniques, we find that this association is statistically positive. In particular, for services firms a 1 percentage point increase in R&D offshoring raises the demand for researchers by about 11 per cent.     

Economic Effects of the Syrian War and the Spread of the Islamic State on the Levant

This paper uses a global computable general equilibrium framework with new detail on six Levant countries – the Arab Republic of Egypt, Iraq, Jordan, Lebanon, the Syrian Arab Republic and Turkey – to quantify the direct and indirect economic effects of the Syrian war and the advance of the Islamic State on the Levant. Syria and Iraq bear the brunt of the direct economic costs, while the other Levant countries lose in per capita but not in aggregate terms as the inflows of refugees increase the size of their populations. The war has undermined progress towards deeper regional trade integration, thus adding to varying degrees to the direct costs sustained by the Levant economies and, in the cases of Syria and Iraq, doubling their welfare losses. All Levant countries are foregoing opportunities to expand intra‐Levant trade and the associated gains in economic efficiency. The average welfare effects are not indicative of the distributional effects of war within countries.     

A Calibrated Group Decision Process

In practice most organisational decisions are made by groups that bring into the problem multiple perspectives, both complementary and contradictory. When having a group of decision makers, usually individuals’ preferences are either led to consensus or are aggregated with the use of some function like the median, the arithmetic or geometric mean. We focus in the second case, where individual’s preferences need to be aggregated. Our approach is based on the fact that when two decision makers are asked to give their preference between a pair of criteria using a specific scale, it is possible that they will give slightly different answers, even when they actually have the same opinion. This difference will not affect the case of a single decision maker, as it will be consistent throughout the whole process. However, it can affect a group decision when the values will be used as an input for the aggregation function. A novel approach is presented that enhances group decision making through a group calibration process. The proposed process adjusts individuals’ preferences based on their answers on a set of standardized questions prior to the aggregation phase. The method focuses The whole concept is applied to the group analytical network process method and it is illustrated through a telecommunications project case. The decision under examination concerns the selection of the right place for deploying a new telecom service of a multinational-based telecommunications company where a group of geographically dispersed decision makers form an ad-hoc virtual team in order to select the location for a new technical support centre.

Mergers and acquisitions & trade: A global value chain analysis

The present paper deals with how the insertion in international trade and global value chains (GVCs) of countries affects their capacity of attracting foreign mergers and acquisitions (M&As). To this end, we combine data for bilateral M&As and trade in value added for the period 2001–15 and estimate an augmented gravity equation. Results indicate that trade openness per se does not favour M&As. Nevertheless, bilateral free trade agreements, heterogeneity of destinations (sources) for exports (imports) of intermediate and final goods, and position and participation in global value chains are relevant for explaining bilateral M&As. Moreover, their role is significantly different depending on the level of development of the home and host countries.     

The dark side of buyer-supplier relationships: A social capital perspective

The literature on supply chain management (SCM) has consistently promoted the “bright side” of collaborative buyer-supplier relationships (BSRs). Based on the social capital argument, SCM scholars have investigated how a buyer can gain access to and leverage resources through its collaborative BSRs. Our study extends this research stream by considering the “dark side” of social capital in BSRs. It evaluates how social capital in its cognitive, relational, and structural forms contributes to or impedes value creation within BSRs. Both primary survey measures and secondary objective measures have been used in data analysis. The results show the presence of both the bright side, confirming the existing literature, and the dark side, extending the literature. There is an inverted curvilinear relationship between social capital and performance: Either too little or too much social capital can hurt performance. This study confirms that building social capital in a collaborative BSR positively affects buyer performance, but that if taken to an extreme it can reduce the buyer's ability to be objective and make effective decisions as well as increase the supplier's opportunistic behavior. Our study also examines how a buyer can delay the emergence of the dark side. It opens up new research avenues in the collaborative BSR context and suggests directions for future research and practice.     

How do female entrepreneurs perform? Evidence from three developing regions

Using the World Bank Enterprise Survey data, we analyze performance gaps between male- and female-owned companies in three regions—Eastern Europe and Central Asia (ECA), Latin America (LA), and Sub-Saharan Africa (SSA). Among our findings are significant gender gaps between male- and female-owned companies in terms of firm size, but much smaller gaps in terms of firm efficiency and growth (except in LA). Part of the reason women run smaller firms is that they tend to concentrate in sectors in which firms are smaller and less efficient (in ECA and SSA). By contrast, we find no evidence of gender discrimination in access to formal finance in any of the three regions, although in ECA women are less likely than men to seek formal finance. Finally, while female entrepreneurs receive smaller loans than their male counterparts, the returns from each dollar they receive is no lower in terms of overall sales revenue.
