Risk sharing in supplier relations: an agency model for the Italian air‐conditioning industry

This study of risk sharing in the Italian high precision air conditioning (AC) industry confirms agency theory predictions that buyers absorb risk to a non‐negligible degree, and that they absorb more risk (a) the greater the supplier's environmental uncertainty, (b) the more risk averse the supplier, and (c) the less severe the supplier's moral hazard. The analyzed buyers accommodate for unforeseen and uncontracted‐for cost fluctuations, which is consistent with relational contract theory. The study clarifies the relationship between risk sharing and the supplier's size, technological capability, financial stability, and cost fluctuation. It also suggests how buyers may adjust their risk‐sharing strategy as suppliers grow, develop technological capabilities, and change financial structure.

China and India in the global economy

The purpose of this overview paper is to present the economic growth in China and India over the last three decades with a specific focus on the integration of these countries into the global economy. In the first part, we briefly review the long-run process of growth and institutional change, emphasizing the reforms leading to the “opening” of the two economies. Then, we focus on key structural features and compare the recent development processes of the two countries. At the end, there are some hints about certain persisting imbalances and the sustainability of the growth processes.     

From central planning towards a market economy: The role of ownership and competition in Vietnamese firms’ productivity

This paper examines the role of ownership and market competition in Vietnamese firms’ total factor productivity (TFP) from 2001 to 2011. Making use of a large panel dataset of manufacturing firms, we find that, on average, both foreign-owned enterprises (FOEs) and state-owned enterprises (SOEs) have performed better than privately owned enterprises (POEs) in terms of their TFP levels. However, while FOEs’ TFP ranked the highest in the period 2001–2006, SOEs “closed the gap” in the period 2007–2011. Moreover, we find that market competition has been effective in enhancing average firm productivity and in reducing the gaps in efficiency across ownership types. SOEs’ remarkable performance may be linked to several concurrent factors experienced during the period 2001–2011, namely, the process of restructuring the state sector during the 2000s, the increased economic integration due to the country's accession to the World Trade Organization (2007) and, finally, the preferential access to financial capital and land granted to SOEs. While some evidence supports SOEs’ equitization as an explanation for their remarkable productivity performance, WTO accession and cheaper access to inputs do not fully explain it.     

The effects of environmental policies on the abatement investment decisions of a green firm

This paper focuses on environmental policies aimed at rising investment in pollution abatement capital. We assume that ecological uncertainty, i.e., uncertainty over the dynamics of pollution, affects firm investment decisions. Capital irreversibility is not postulated but endogenized using a quadratic adjustment cost function. Using this framework, we study the effects of environmental policies considering taxes on polluting inputs and subsidies to reduce the cost of abatement capital. Environmental policies promoted to enforce abatement capital may generate the unexpected result of reducing the abatement investment rate.     

Towards a non-Darwinian Theory of Institutional Change

The paper emphasizes two flaws in mainstream economics: the failure to understand actual human behavior in many real contexts and the failure to take account of transaction costs. By emphasizing the role of knowledge, institutions, transaction costs and path dependence, new institutional economics has provided a powerful answer to these shortcomings. Nevertheless, a number of questions remain open. In particular, path dependence is far from being a continuous process. Its dynamics and its irregularities are by and large unexplained. Hence, a strong need for a convincing evolutionary theory of environmental change. This article does not deny the validity of the Darwinian view applied to the theory of the firm and of competition in a free-market economy. The paper, however, maintains that the natural-selection process that characterizes the Darwinian approach is ill suited to describe economic evolutionary processes. It is shown that a combination of functional analysis and natural selection may indeed be a better solution, for it solves some of the puzzles raised by public choice theory without violating the fundamental tenets of the new institutional economics approach. Still, although this combined view may well explain why the institutional features are retained by the system, it does not clarify why they are introduced in the first place. A third possibility is put forward in the second part of the paper, where a new evolutionary theory is suggested. Within this framework, agents are assumed to behave according to their preferences within the existing rules of the game. At the same time, new ideas and sometimes new ideologies may influence their behavioral patterns. The combination between needs and ideologies generates environmental change, especially if so-called ideological entrepreneurs are able to transform latent and shared beliefs into an institutional project and enforce it.     

Two remarks on the inner core

For the case of smooth concave exchange economies, we provide a characterization of the inner core as the set of feasible allocations such that no coalition can improve on it, even if coalitions are allowed to use some random plans. For the case of compactly generated games, we discuss Myerson's definition of the inner core, and we characterize it using lexicographic utility weight systems.     

On the existence of involuntary unemployment equilibria

Conclusion We have proved the existence of equilibria implying involuntary unemployment of labour in non-competitive economies with fixed wage rate. We notice that model (II) and its extensions have not been presented as aninterpretation of Keynes' theory. We may define them as Keynesian models only in the sense that they admit involuntary unemployment equilibrium, which concept is basic to Keynes' theory. In any case, we think that these models are a first step in the development of more realistic microeconomic foundations for short-run macroeconomic theory.A first draft of this paper was presented in December 1972 at the Institute of Political Economy, Faculty of Economics and Banking, Siena University.     

DIRECTED GRAPH THEORY AND THE ECONOMIC ANALYSIS OF INNOVATION

This article applies digraph theory to the theory of technological regimes. The first part of the paper identifies a number of links between the evolutionary approach and a particular version of the neoclassical approach to the economic analysis of technological change. Both these approaches are shown to take the body of presently-available technological knowledge as a quantifiable magnitude allowing firms varying in strategy, structure and core capabilities to explore a range of feasible alternatives within the frontiers imposed by such knowledge. The second part of the paper therefore considers technological knowledge to be a cognitive empirical structure which can be better defined and calculated by using the theorems of digraph theory.
