Indeterminacy, underground activities and tax evasion

This paper introduces underground activities and tax evasion into a one-sector dynamic general equilibrium model with aggregate external effects. The model presents a novel mechanism driving the self-fulfilling prophecies, which is characterized by well behaved (downward sloping) labor demand schedules. This mechanism differs from the customary one, and it is complementary to it. Compared to traditional labor market income, the income derived from underground labor activity is subject to a lower expected tax rate when considering both the probability of detection and the evasion penalty. During a belief-driven expansion, the household allocates more time to both traditional and underground labor supply. In equilibrium, this action serves to lower the effective labor tax rate faced by the household, thus providing stimulus to aggregate labor supply so as to make the initial expansion self-fulfilling. The mechanism here is akin to a “regressive tax”; the household's effective tax rate depends negatively on the level of total labor income. We argue that an underground sector, and the associated tax evasion, offer a good economic rationale for a regressive tax rate.     

From Which Source Do Small Firms Derive Their Innovative Inputs? Some Evidence from Italian Industry

This paper relies upon the hypothesis that the “knowledge production function” – defined in the geographical sense – is characterized by coefficient estimates which vary with firm size. In particular, large firms depend for their innovative output on direct and indirect R&D inputs, whereas small firms more extensively exploit the spillovers from research activities carried out by universities and by other firms. This hypothesis is tested against two different sets of data: the first based on patent statistics and dealing with 20 Italian regions over the period 1978–86; the second consisting of a selected number of product innovations identified by a literature-based counting procedure and dealing with 46 Italian provinces in year 1989. The results of regression analysis support the hypothesis that firms belonging to different size classes resort to different sources for the knowledge relevant to their innovative output. In particular, industry R&D prove to play a relatively more important function than do spillovers from university research in generating innovative output in large firms, whereas the opposite is true in the case of small firms.     

Barking Up the Wrong Tree: A Reply to Haynes & Husan

The Albanian economy in the 1990s experienced a rapid recovery from its near-collapse in 1992. The rapid economic growth between 1993 and 1996 was exceptional by East European standards, and represented the highest rate of sustained economic growth of all transition economies. This investigation indicates that the standard explanations for recovery and growth in transition economies, such as the pace of economic reform or the levels of domestic and foreign investment, do not adequately explain the rapid growth of the Albanian economy. Factors specific to Albania also need to be considered. The main conclusion drawn here is that the success of the Albanian economy in the mid-1990s rested largely upon the inflow of remittances from Albanians working abroad. These remittances are shown to have been much greater in value than was previously assumed by the IMF: in the region of $700 million per annum rather than $400 million. Remittances are also found to have played a much greater role in Albania's economic recovery than was previously recognised. It is demonstrated that the rise of pyramid investment schemes in 1996 was closely linked to the inflow of remittances. Such schemes are also found to have played a part in fuelling the rapid economic growth in the Albanian economy, before their collapse in 1997.     

Diversification preferences in the theory of choice

Diversification represents the idea of choosing variety over uniformity. Within the theory of choice, desirability of diversification is axiomatized as preference for a convex combination of choices that are equivalently ranked. This corresponds to the notion of risk aversion when one assumes the von Neumann–Morgenstern expected utility model, but the equivalence fails to hold in other models. This paper analyzes axiomatizations of the concept of diversification and their relationship to the related notions of risk aversion and convex preferences within different choice theoretic models. Implications of these notions on portfolio choice are discussed. We cover model-independent diversification preferences, preferences within models of choice under risk, including expected utility theory and the more general rank-dependent expected utility theory, as well as models of choice under uncertainty axiomatized via Choquet expected utility theory. Remarks on interpretations of diversification preferences within models of behavioral choice are given in the conclusion.     

Industrial districts and internationalization: the case of the agri-food industry in Modena,Italy

The paper explores the structural changes, in response to internationalization, in an important traditional activity (food chain, meat processing) in a typical ‘district area’. In the paper, attention is focused on the ‘Institutional structure of production’ (Coase, R. 1992 Coase, R. 1992. The institutional structure of production. American Economic Review, 82(4): 713–719. [Web of Science ®] , [Google Scholar]) and the cluster is considered as a whole, as a complex economic player, capable of generating coherent action, regulated by institutional mechanisms, and founded on a set of ‘public assets’ which make up its ‘social capital’.

The paper is based on many empirical studies and surveys aimed at exploring the structure of SMEs and the role of the local institutions: the changes observed over time and in response to internationalization underline the reinforcement of the activity's cluster configuration.

These features emphasize the existence of a specific unit of analysis, indivisible from the individuals which constitute it. The discussion touches on the classical themes of the efficiency of the net-economy based on SMEs, and their prospects in a context of growing globalization.

The paper does not aim to enter into the debate on the origins and mechanism of innovation. However, the case study does illustrate the strength of the hypothesis of a unit of analysis different from the firm for discussion of a number of topics: some empirical examples of innovation, of significance for the economic consolidation of the ID, highlight the importance of district relationships in the production and spread of innovation.     

Skills,sunspots and cycles

This paper explores the ability of a class of one-sector, multi-input models to generate indeterminate equilibrium paths, and endogenous fluctuations, without relying on factors’ hoarding. The model presents a novel theoretical economic mechanism that supports sunspot-driven expansions without requiring upward sloping labor demand schedules. Its distinctive characteristic is that the skill composition of aggregate labor demand drives expansionary i.i.d. demand shocks. Next, the model explains the labor market dynamics from the supply side, while endogenizing the capital productivity response to changes in the aggregate labor demand composition. Last but not least, it is worth to mention that the model presents an effective shock propagation mechanism that operates into the labor market and across labor market segments through the cross elasticities of equilibrium labor demand and supplies.      

Resource interaction in inter-organizational networks: Foundations, comparison, and a research agenda

The focus of this article is on discussing the foundations, conceptual development, and implications of resource interaction in inter-organizational networks. The article conceptualizes and classifies resources before discussing how resource interfaces enable to utilize, manage, and change resources. In doing so it provides a set of basic principles as to how resources interact at a network level, or how firms combine, develop, mobilize, and manage resources over time. This is in strong contrast to a focus on the acquisition, accumulation, and exchange of resources by the firm. The article further provides a comparison with two other research streams, the Resource-Based view (RBV) and the Service-Dominant logic (S-D logic), in order to better position this perspective on inter-organizational resource interaction. It concludes by discussing an agenda for further research.     

Collaboration for innovation and project failure. A dynamic analysis

The aim of this paper is to investigate the hypothesis that there is a complex and bidirectional relation between collaboration and failure in innovation projects. On the one hand, collaboration in innovative activities may increase the likelihood of project failure. At the same time, the failure in innovation projects may induce the firm to collaborate in order to overcome the problems that determined the failure of innovation projects (induced collaboration). Up to now, we are not aware about the existence of any empirical paper analysing the interaction between these two mechanisms. This paper aims at filling this gap by providing a motivation for the induced collaboration and testing its empirical relevance in a dynamic framework. The empirical analysis is carried out by using two consecutive German Community Innovation Surveys referring to the period 2006–2010. The empirical results support the hypothesis of a bidirectional causal relationship between collaboration and failure.     

Patience and time consistency in collective decisions

We present experimental evidence regarding individual and group decisions over time. Static and longitudinal methods are combined to test four conditions on time preferences: impatience, stationarity, age independence, and dynamic consistency. Decision making in groups should favor coordination via communication about voting intentions. We find that individuals are neither patient nor consistent, that groups are both patient and highly consistent, and that information exchange between participants helps groups converge to stable decisions. Finally we provide additional evidence showing that our results are driven by the specific role of groups and not by either repeated choices or individual preferences when choosing for other subjects.
