DISAGGREGATING INPUT–OUTPUT MODELS WITH INCOMPLETE INFORMATION

Disaggregating a sector within the Leontief input–output (IO) framework is not a straightforward task since there is more than one possibility for the unknown technical coefficients of the disaggregated IO table, and more information than what is embodied in the aggregated IO table is thus required. This paper presents a methodology for disaggregating sectors into an arbitrary number of new sectors when the only available information about the newly formed sectors is their output weights. A random walk algorithm is used to explore the polytope containing the admissible combinations for the unknown technical coefficients of the disaggregated IO table. These combinations are then used to construct the probability distribution of the coefficients of the inverse Leontief matrix. The methodology is illustrated by disaggregating the electricity production sector of China's 2007 IO table and by looking at the probability distribution of the CO₂ emission intensity factors of the sectors of the economy.     

MARKET PRICE MECHANISMS AND STACKELBERG GENERAL EQUILIBRIA: AN EXAMPLE

This paper considers Stackelberg competition in a general equilibrium framework with a productive sector. The working of market power and the configurations of strategic interactions are complexified by the presence of a leader. Two market price mechanisms are studied: one is associated with the Stackelberg–Walras equilibrium and the other is linked to the Stackelberg–Cournot equilibrium. Throughout the example of a two commodity economy, several results are obtained about equilibria mergings and about welfare comparisons.     

On Stackelberg competition in strategic multilateral exchange

In this paper, we consider a strategic equilibrium concept which extends Stackelberg competition to cover a general equilibrium framework. From the benchmark of strategic market games proposed by Sahi and Yao (1989), we define the notion of Stackelberg equilibrium. This concept captures strategic interactions in interrelated markets on which a finite number of leaders and followers compete on quantities. Within the framework of an example, convergence and welfare are studied. More specifically, we analyze convergence toward the competitive equilibrium and make welfare comparisons with other strategic equilibria.     

The impact of unconventional monetary policy on the market for collateral: The case of the French bond market

We consider the channel consisting in transferring the credit risk associated with refinancing operations between financial institutions to market participants. In particular, we analyze liquidity and volatility premia on the French government debt securities market, since these assets are used as collateral both in the open market operations of the ECB and on the interbank market. In our time-varying transition probability Markov-switching (TVTP-MS) model, we highlight the existence of two regimes. In one of them, which we refer to as the conventional regime, monetary policy neutrality is verified; in the other, which we dub the unconventional regime, monetary policy operations lead to volatility and liquidity premia on the collateral market. The existence of these conventional and unconventional regimes highlights some asymmetries in the conduct of monetary policy.     

The Shrinking Hand: Why Information Technology Leads to Smaller Firms

We explain the firm downsizing trend of the recent decades by the new abundance of information – the ICT revolution. Production processes differ in their information requirements: while decentralized production by means of market exchanges is information intensive, less information per unit of output is needed in the hierarchically integrated production of firms, and the information/output ratio is decreasing firm size.

We formulate a quantity of information theory of the firm embodying these differences and derive a Coase–Rybczinski effect for the aggregate economy, which predicts a decreasing employment share of large firms and an increasing share of small ones when the aggregate quantity of information increases Panel data regressions and other evidence provide support for this hypothesis.     

Mathematical formulation and exact solution for landing location problem in tropical forest selective logging,a case study in Southeast Cameroon

In Central Africa, creating forest roads and skid trails is one of the most costly and environmentally damaging operations for the forest's ecosystem. An optimized road network is essential for reducing construction costs and improving the sustainable management of timber resources. The location of landings is vital in the development of a future forest road network. In this study, a binary integer programming model similar to the uncapacitated facility location problem is formulated to optimize the locations of the landings. The model is applied to selective logging in Central Africa and tested on an annual logging zone in Southeast Cameroon. The results are compared to that of manual road planning, the currently used method.     

When do better schools raise housing prices? Evidence from Paris public and private schools

In this paper, we investigate how housing prices react to the quality of education offered by neighboring public and private schools. The organization of secondary schooling in the city of Paris, which combines residence-based assignment to public schools with a well-developed and almost entirely publicly funded private school system, offers a valuable empirical context for analyzing how private schools affect the capitalization of public school performance in housing prices. Using comprehensive data on both schools and real estate transactions over the period 1997–2004, we develop a matching framework to carefully compare sales across school attendance boundaries. We find that a standard deviation increase in public school performance raises housing prices by 1.4 to 2.4%. Moreover, we show that the capitalization of public school performance in the price of real estate shrinks as the availability of private schools increases in the neighborhood. Our results confirm the predictions of general equilibrium models of school choice that private schools, by providing an advantageous outside option to parents, tend to mitigate the impact of public school performance on housing prices.     

Inter- and intra-industry linkages as a determinant of FDI in Central and Eastern Europe

This paper uses an unpublished dataset on disaggregated foreign direct investment (FDI) in Central and Eastern European countries (CEECs), and is rooted in new economic geography literature. A 10% increase in access to suppliers based in the FDI recipient country or access to the EU15 market for intermediate goods increases FDI by about 2% in Central European countries and by 1% in Eastern European countries. We argue that Central (core) European countries specialise in upstream industries and re-export goods toward FDI-origin countries, while Eastern (periphery) European countries are also involved in this production chain, but to a lesser extent.     

La gouvernance des organisations de l’Economie Sociale et Solidaire à l’épreuve dynamique de leurs « Grandeurs »

THE DYNAMICS OF PLURAL ‘WORTH’ AS A CHALLENGE TO THE GOVERNANCE OF SOCIAL AND SOLIDARITY‐BASED ECONOMY ORGANIZATIONS This article resorts to Boltanski and Thevenot's Economies of Worth model (1987, 1991) to examine from a theoretical stance the various institutional logics competing in social and solidarity‐based economy organizations (SSEOs). The originality of our approach does not lie so much in the identification of the main conventions shaping the governance of SSEOs, but rather in the analysis of the conflicts and achievable compromises among each of these polities. Our contribution is threefold. We first show that the competition among several conventions generates organizational conflicts that are difficult to solve. We then reveal that achieving an (ephemeral) compromise entails a risk of excluding a ‘polity’, which may in turn weaken the governance of SSEOs. We finally sketch out some perspectives allowing to mitigate this risk. In particular, we outline organizational strategies likely to frame the governance of SSEOs without impairing their identities and plural forms of ‘worth’.
