The price of anarchy of serial, average and incremental cost sharing

We compute the price of anarchy (PoA) of three familiar demand games, i.e., the smallest ratio of the equilibrium to efficient surplus, over all convex preferences quasi-linear in money. For any convex cost, the PoA is at least in the average and serial games, where n is the number of users. It is zero in the incremental game for piecewise linear cost functions. With quadratic costs, the PoA of the serial game is , and for the average and incremental games. This generalizes if the marginal cost is convex or concave, and its elasticity is bounded.      

Walrasian analysis via two-player games

We associate to any pure exchange economy a game with only two players, regardless of the number of consumers. In this two-player game, each player represents a different role of the society, formed by all the individuals in the economy. Player 1 selects feasible allocations trying to make Pareto improvements. Player 2 chooses an alternative from the wider range of allocations that are feasible in the sense of Aubin. The set of Nash equilibria of our game is non-empty and our main result provides a characterization of Walrasian equilibria allocations as strong Nash equilibria of the associated society game.     

Determinants of long-distance investing by business angels in the UK

The resource-based view (RBV) of the firm has been applied to territories, although academia has not frequently undertaken exploration of RBV applied to clusters in an empirical base. The goal of this paper aims at empirically translating RBV to the territory with a double objective. First, the work seeks to understand which are the cluster's resources and capabilities. Second, the paper evaluates whether a cluster's unique set of resources and capabilities could influence a cluster's performance. Research is applied to leading European ceramic tile clusters located in Spain (Castellon) and Italy (Emilia-Romagna). Comparing clusters in the same industry allows benchmarking and the metrics make more sense. Secondary data and face-to-face semi-structured interviews with managers from the R&D Institutes, institutional agents and Castellon (59) and Emilian (19) firms assess a cluster's resources and capabilities. The employed variables address skilled labour availability, social capital, linkages, business sophistication and network effects. In addition, and through the utilization of financial and productivity data the work analyses whether there are performance differences. Results indicate that clusters have a unique set of resources and capabilities and a certain performance level. On the whole, a cluster's unique set of resources and capabilities matter. The paper offers a methodological approach to tackle empirically the RBV application to clusters.     

Mergers and Acquisitions in European banking higher productivity or better synergy among business lines?

This paper aims at assessing the extent to which M&As in European banking sector over the period 1996–2003 result in two simultaneous catching up and convergence processes of consolidating groups. First, do the M&As significantly contribute to the consolidating banks to catch-up with the productivity benchmark? Second, in terms of synergies or complementarities among business lines, is there a convergence process of output mixes among the individual banks of the M&A operations? Our sample is made up of 42 M&A transactions and 587 non-merging banks in Europe. The main conclusion is that M&A operations in the European banking industry appear to be essentially motivated by an objective of improving complementarities among lines of work from each component of M&As rather than increasing productivity at the merged banks.     

Production externalities: internalization by voting

We study internalization of production externalities in perfectly competitive markets where production plans are decided by majority voting. Since shareholders want firms to maximize dividends of portfolios rather than profits, they are interested in some internalization. Two governances, namely the shareholder governance (one share, one vote) and the stakeholder democracy (one stakeholder, one vote), are compared. We argue that perfect internalization is more likely to be the outcome of the stakeholder democracy than the shareholder governance.     

The OECD's new global model

This paper provides a summary of the OECD's new global macroeconometric model, including an overview of model structure and a selection of simulations illustrating its main properties. Compared with its predecessors, the new model is more compact and regionally aggregated, but gives more weight to the focus of policy interests in global trade and financial linkages. The country model structures typically combine short-term Keynesian-type dynamics with a consistent long-run neo-classical supply-side. While retaining a conventional treatment of international trade and payments linkages, the model has a greater degree of stock-flow consistency, with explicit modelling of domestic and international assets, liabilities and associated income streams. Account is also taken of the influence of financial and housing market developments on asset valuation and domestic expenditures via house and equity prices, interest rates and exchange rates. As a result, the model gives more prominence to wealth and wealth effects in determining longer-term outcomes and the role of asset prices in the transmission of international shocks both to goods and financial markets.     

Qualification as corporate activism: How Swedish apparel retailers attach circular fashion qualities to take-back systems

This paper explains how corporations can develop market-based activities to influence environmental policies. The empirical focus is on how Swedish apparel retailers qualify take-back systems for used clothes and textiles as steps toward creating circular fashion. An analysis of the qualities that retailers attach to take-back systems shows how qualification helps corporations feature fashion as potentially sustainable and able to develop circular material flows, with the aim to enroll staff, customers, and other stakeholders in new behaviors and patterns of responsibility. We apply the notion of corporate activism to demonstrate how corporations use qualification to engage in market-based activities with the aim of influencing the regulatory agenda.     

The Convergence of Price–cost Margins

This paper provides estimates of sectoral price–cost margin (PCM) trends in thirteen OECD countries over the last three decades, once controlled for inflation and cycle effects. It concludes with the absence of a decrease in average PCM. More strikingly, it establishes a clear pattern of PCM convergence both across countries and sectors. This convergence means that high margins have shrunk and low margins grown. Better capital market efficiency might be a driving force in the PCM convergence. These results point to a need to search for factors countervailing the pro-competitive effect on markups. The views expressed in this paper are those of the author and do not necessarily represent those of the OECD or its member countries.
