PAYG pensions, tax-cum-subsidy and A-Pareto efficiency

An overlapping generation’s small open economy with endogenous fertility and time cost of children is analysed to show that the command optimum can be decentralised in a market setting using a PAYG transfer from the young to the old and a tax-cum-subsidy policy (i.e., a linear wage tax on labour income collected and rebated in a lump-sum way within the younger working-age generation). Indeed, the latter instrument stimulates fertility and then reduces the opportunity cost of children. Moreover, by applying the generalised notion of Pareto efficiency introduced by Golosov et al. (2007) in a context of endogenous population, some normative conclusions can be drawn: since only the utilities of those who are actually born are evaluated, we apply the concept of A-efficiency and conclude that when PAYG pensions are in existence, the tax-cum-subsidy policy can effectively be used as an alternative to the child allowance to internalise the externality of children, while also representing an A-Pareto improvement.     

Walras’ theory of capital formation: an intertemporal equilibrium reformulation

We develop a mainstream reformulation of the original Walras?? model of capital accumulation. We overcome the shortcomings of the original model. First, we prove the existence of intertemporal competitive equilibria. Our proof combines a well known theorem due to Yannelis and Prabhakar (J Math Econ 12:233?C245, 1983) with a lemma due to Geanakoplos (Econ Theory 21:585?C603, 2003). Secondly, we remedy the indeterminacy of allocation of savings across multiple types of capital goods by introducing a storage technology. Finally, we show that, for stored capital goods, the equality of rates of returns emerges endogenously in equilibrium, while it was imposed by Walras from the outset in his original contribution.     

Inter-firm knowledge diffusion, market power, and welfare

We propose an infinite-horizon quantity-setting differential game with learning spillovers and organizational forgetting to analyze the optimal management decisions affecting the evolution of the stock of know-how, and, in turn, the dynamics of productive efficiency. Specifically, we study the long run impact of inter-firm knowledge diffusion on market power, i.e. the ability of a firm to raise the price above the marginal cost, and welfare. We consider two types of processes through which knowledge is acquired: (i) passive learning, or learning-by-doing, where managers do not actively invest in information and (ii) active learning, or learning-by-investing, where managers acquire new and additional information through specific investments in human capital. We show that: under (i), knowledge diffusion reduces market power; under (ii), knowledge diffusion reduces market power as long as learning spillovers are sufficiently important. From a welfare viewpoint, we also show that: under (i), knowledge diffusion is always welfare-enhancing; under (ii), weak spillovers are required in order for knowledge diffusion to be welfare-enhancing.     

Bargaining and Devolution in the Upper Guadiana Basin

Increasingly, central governments approach contentious natural resource allocation problems by devolving partial decision-making responsibility to local stakeholders. This paper conceptualizes devolution as a three-stage process and uses a simulation model calibrated to real-world conditions to analyze devolution in Spain’s Upper Guadiana Basin. The Spanish national government has proposed spending over a billion euros to reverse a 30 year decline in groundwater levels. We investigate how the government can most effectively allocate this money to improve water levels by utilizing its power to set the structure of a local negotiation process. Using a numerical Nash model of local bargaining, we find that if the national government creates appropriate incentives, local bargaining can produce water stabilization. The actual water levels that will emerge are highly dependent on the central government’s decisions about the budget available to local stakeholders and the default policy, which will be influenced by the relative value the government places on various financial and environmental outcomes. Our paper concludes by determining the relationship between these relative valuations and the government’s preferences over water levels.     

Accounting relativism: the unstable relationship between income measurement and theories of the firm

The knowledge structures underlying accounting representations are rarely investigated and usually tend to be taken for granted. As a case of the problematic knowledge foundations of accounting, we concentrate on one of the most relevant conceptual underpinnings informing the construction of the accounts—the relationship between theories of the firm, accounting theories, and income measurement. In particular we analyse and compare the ways in which this relationship has been conceived and developed in two theoretical contexts, the Italian tradition of Economia Aziendale and the US entity vs proprietary debate. Various and contradictory approaches to the concept of the firm and income calculation in these two theoretical traditions emerge. Such a conceptual variety is what we refer to as ‘accounting relativism’. This is defined here as the co-existence of different accounting representations and measurements, both of which are not objectively rankable in any conceptual hierarchy, because of the incommensurability of their basic assumptions, i.e. of their knowledge bases. This intrinsically ‘unstable’ character of accounting at a conceptual level is likely to have relevant implications, representing a major source of theoretical variety, as well as a premise for making sense of power uses of accounting within organisational settings. ©     

THE REAL EXCHANGE RATE AND THE BALASSA–SAMUELSON EFFECT: THE ROLE OF THE DISTRIBUTION SECTOR

Abstract. This paper investigates the long‐run impact of the distribution sector on the real exchange rate. The main result is that an increase in the productivity and product market competition of the distribution sector with respect to foreign countries leads to an appreciation of the real exchange rate, similar to what a relative increase in the domestic productivity of tradables does. This contrasts with the result that one would expect by considering the distribution sector as belonging to the non‐tradable sector. One explanation may lie in the use of the services from the distribution sector in the tradable sector.     

The emergence of career boundaries in unbounded industries: career odysseys in the Italian New Economy

The main objective of this research1 was to study boundaries to the ‘boundaryless career’ in a novel context. Our empirical study focused on career paths leading top managers to enter emergent firms. We collected data on professional histories of a sample of top managers who operated in firms listed at the ‘Nuovo Mercato’ (New Market), the Italian equivalent of the NASDAQ. We demonstrate the existence of two major kinds of boundaries: competence-based (in the form of industry boundaries) and relation-based (in the form of professional network boundaries). A second objective of our research was to identify dominant individual career logics and to connect different career logics to the boundaryless career concept. Our data reveal the dominance of the evolutionary career logic.     

Three Decades of Italian Comparative Advantages

This paper explores the structure of Italian revealed comparative advantages (RCA), focusing on the export structure itself, on its changes over time and on its degree of persistence. The analysis is developed with the use of visual statistical tools and non‐parametric statistical techniques that allow to estimate the empirical distribution of the Balassa (1965) index, and to track its dynamics during three decades, from the 1970s to the present. The main results of the analysis are that the structure of Italian RCA is highly persistent, but is changing; the structure is very different when it is examined at a macro‐regional level; the distribution is not so similar to the one of the new industrialised countries, when it is examined at a high level of sectoral disaggregation. Finally, the persistence in the pattern of RCA appears to be positively related to the presence of industrial districts in export data disaggregated at the provincial level.
