## Abstract

Riassunto. – All’interno della comunità degli economisti sembra essere oggi presente un crescente disagio e un diffuso malcontento relativamente alle capacità della modellistica neoclassica di comprendere e spiegare i fenomeni economici. La relazione intende esaminare criticamente il contributo della formalizzazione matematica nelle teorie economiche, mettendo in evidenza sia punti di forza di un tale approccio sia le debolezze insite in un’analisi che rischia spesso di privilegiare la bellezza dello strumento rispetto all’oggetto di studio. Si considerano poi alcune delle moderne prospettive per l’indagine economica offerte dalla modellistica basata sulla simulazione a computer che consente di tener conto della complessità della realtà in misura maggiore di un approccio puramente analitico. Viene infine evidenziata l’importanza di garantire la coesistenza di una pluralità di scuole di pensiero in economia e si esaminano altresì le difficoltà per la valutazione della ricerca provocate dall’esistenza di un paradigma dominante. Nelle conclusioni viene enfatizzata la necessità di considerare l’economia come una vera scienza sociale.***Abstract. – There is today a widespread discontent within the international economists’ community as far as the capacity of the dominant neoclassical paradigm both to enhance our knowledge of economic phenomena and increase our capacity of governing the real economy. Somehow surprisingly, the lack of explicative relevance of the theory went almost hand in hand with the massive use of mathematics to formalize the theory. In order to investigate this peculiar feature of the evolution of economic science, this paper examines the contribution of mathematical formalization to the development of economic theory in the last sixty years pointing out both weaknesses as well as merits of a quantitative approach to economics. Finally, the need to consider economics as a truly social science si strongly emphasized.

### The concept of multiple equilibria in social sciences

June 2011 · Revista de Economía Institucional

The concept of equilibrium has become the centerpiece of modern economic analysis. Moreover, it has provided the impetus behind the expansion of economic theory into areas of the social sciences that used to be regarded as remote. The current paper aims at explaining the changes in economic science that have brought about this process, while at the same time offering a cursory discussion of the ... [Show full abstract] foundations of the concept of equilibrium, its strengths, the methodological challenges it presents, especially as regards the case of "multiple equilibria", and a sketch of alternatives that could tackle said challenges.

### The Contribution of the Neo-Schumpeterian Approach to the Development of the Economic Theory: Emphas...

July 2011

This article tries to show that there are alternative approaches to the economic theory, besides the well-known economic schools, Classicism, Neoclassicism and Keynesianism. The neoclassical principles allow a formalization – widely accepted by experts – that provide effective tools for measuring the effects of the economic activity. The economic science pays a special attention to the study of ... [Show full abstract] the economic agents’ behaviors, and to the economic results obtained by them through economic activity. Any human science uses principles and works with assumptions, and the neoclassical assumptions have generated efficient tools for quantifying the economic outcomes, and for accounting the economic growth. But these hypothesis, such as the assumption of economic agents’ rationality, allow a very limited understanding of the behaviors of economic agents within the markets. The recent invention of the Nuclear Magnetic Resonance device, allowed the emrgence of a new scientific paradigm, the development of neurosciences. Researchers can observe at a high level of graphic detail various types of activities that occur in the human brain, and some economists have introduced in the study of the economic theory, for example, the assumption that the consumer is driven by emotions when purchasing quantities of goods and services. So, economists may look for additional theories to explain the behavior of the economic agents. An increasingly importance is given to the theoretical contributions built on the work of the economist Joseph Alois Schumpeter, who has an original economic approach based on his own principles. It is proposed to focus the attention on a mesoeconomic vision about the industry, to understand how resources are being allocated and reallocated between companies, and to study the economic processes of evolution, which are influenced by the emergence and dissemination of the innovations. It is supposed that the price is allocating the resources in the economy, but the companies’ behavior is generated by a competition and cooperation for innovation.

### The Utilitarian Paradigm

February 2013

The chapter presents an extensive revision of the utilitarian assumptions that are implicit in economic science – in the socializing and statist version as well as in the liberal and individualist one. According to Rosmini, this implicit utilitarian conception is not due to political economy as a science but to the philosophical influence of utilitarian theories suffered by many economists. The ... [Show full abstract] heart of the utilitarian influence in modern economic science lies, according to Rosmini, in the conception of human action as a behavior always oriented towards maximization of utility. The chapter presents Rosmini’s detailed description of three main different versions of utilitarianism – empiricist or sensist, sentimentalist and eudemonist – and also shows the consequences that these different versions of utilitarianism bring to the conception of society, law, politics and economic science.

### Les explications culturelles du développement économique : Pertinence et faiblesses

January 2002 · Relations internationales

Frequently used by sociologists and political scientists, the culture variable is found to be very largely absent from development analyses as produced by economists. It is admittedly true that the perspective of cultural homogenisation across the planet and the dominance of the rationality paradigm in economic science do not encourage this type of research. However, the works of Max Weber and ... [Show full abstract] lessons from anthropology establish that the homo oeconomicus is far from eternal and universal. But social science contradictions in terms of the economic effects of individualism and religious adherence have contributed to this embroilment of the cultural analysis of development. Fortunately, certain recent works are apparently drawing out new lines for research in this field.

### Pouvoir politique vs puissance des marchés : deux mondes parallèles ?

November 2013

La discussion des rapports entre marché et politique est le plus souvent posée dans des termes caricaturaux: à la fin, l'un est censé l'emporter sur l'autre. A moins, par exemple, qu'on interprète les problèmes de gouvernance économique globale en termes de " guerre économique " : une métaphore particulièrement stérile, qui opacifie les problèmes au lieu de les éclairer. La présente contribution ... [Show full abstract] cherche à reproblématiser la question en insistant notamment sur deux points : d'une part les différences riches et significatives existant entre la première mondialisation (1870-1914) et la phase actuelle (post-1990) ; de l'autre l'idée qu'aujourd'hui, l'engagement des souverains sur la scène internationale est contingente, ou optionnelle, alors qu'au plan local, leur obligation de défendre de la société et la division du travail est imparable. Les souverains agissent plus que jamais localement et sont sanctionnés par leurs citoyens et leur société civile.

### The Prize

January 2015

The Nobel Memorial Prize is the only prize associated with Alfred Nobel that is awarded to the social sciences. Yet Nobel had not actually founded what is now formally called the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. Nobel lamented his creation of dynamite, which had yielded numerous ways to contribute to the social good, but also produced some less benign ... [Show full abstract] applications. When Nobel determined he would create a legacy that would celebrate contributions by intellectuals to the social good, the disciplines of finance and economics had not yet entered the scientific realm. Only with the subsequent development of economics and finance as a social science which could inform and enhance the public good have these disciplines become candidates for recognition by the Nobel Committee.

### The Political Economy of James Buchanan

January 1990

A political economist whose numerous and influential writings explore the no-man's-land that separates the social science disciplines. The founder of the constitutional economics paradigm, Buchanan was awarded the 1986 Nobel Prize in economic science for his contributions to a theory of constitutional political economy as well as his leadership of the public choice movement. In this volume, David ... [Show full abstract] Reisman seeks to explain and analyze the important insights of this difficult but stimulating multidisciplinary figure. Buchanan's recommendation of constitutional precommitment will appeal to all economists who share his conviction that politicians and bureaucrats, where not preconstrained by rules that they cannot alter at will, tend rapidly to become not servants but the masters of the electorate. His determination to define and defend the middle ground, neither anarchy nor Leviathan, will have a wider appeal still.
