A conversational approach to consumer vulnerability: performativity,representations, and storytelling

ABSTRACT

This conceptual article provides a conversational analysis of consumer vulnerability, which unveils how vulnerability is made through conversations and interactions among actors holding different market power positions. Three types of conversations prove fruitful to pursue a transformative research agenda improving vulnerable consumers’ well-being: (1) performativity, which unpacks agency and finalism in conversations; (2) social representations, which reveal uneven power positions and normativity expressed by participants in a conversation; and (3) storytelling, which reveals alternative and more powerful persuasive mechanisms of conversations framed as stories. Illustration for these types of conversations comes from extensive review of the literature on consumer vulnerability and from a critical consideration of my life-as-researcher with consumers as varied as gays, homeless people, migrants, second-generation immigrants, and subcultures of consumption.     

Central Bank Independence and Budget Constraints for a Stable Euro

This paper looks at what economic theory and empirical evidence have to offer about the institutional conditions that are most likely to lead to a stable currency. Both theory and evidence suggest that an independent central bank with the explicit mandate to pursue price stability provides an effective solution to the time-inconsistency problem. The EMU institutional set-up is well-equipped to support a stability-oriented monetary policy. The ECB appears to be the most independent central bank in the world. An added protection of monetary policy from the influence of unsound budgetary policies enhances the prospects of price stability. The Maastricht Treaty and the Pact for Stability and Growth provide effective constraints against excessive deficits and encourage an environment of balanced budgets. The argument that both strong institutional arrangements and sound economic policy-making stem from a conservative attitude of the public is not dismissed altogether in this paper. We note, however, that this hypothesis is not formulated in a testable form and has ambiguous practical consequences. The hypothesis, nonetheless, serves as a useful reminder that the ECB should endeavor to draw its legitimacy not only from the text of the Treaty, but also from society as a whole.     

Cohort,age and time effects in alcohol consumption by Italian households: a double-hurdle approach

This paper describes the life-cycle alcohol consumption patterns of Italian households by decomposing gender, cohort, age and time effects and estimates the importance of demographic characteristics using a double-hurdle model. The application is based on ISTAT households expenditure survey for the period 1997–2002 organized in cohorts. As expected, cohort and age effects are significant in both participation and consumptions. The significance of gender and geographic differences suggests important policy implications.      

Monopoly, Time Consistency, and Dynamic Demands

This paper examines monopolistic behavior in a framework with dynamic demands. We show that time consistent output and pricing policies yield different equilibrium outcomes in terms of profits and welfare. In a simple two-period model, we find that pricing policies impose less restrictive constraints on a producer of addictive goods, allowing him to attain higher equilibrium profits. In contrast, a durable goods producer is better off implementing output policies. We study the effect of instrument selection on the strategic properties of the monopolist’s intra- personal game. Intertemporal substitutabilities imply that current and future prices are strategic complements, while current and future output levels may be strategic substitutes. Intertemporal complementarities reverse the strategic properties of these instruments.     

Advertising effect on primary demand: a cointegration approach

This paper addresses the question of the effects of advertising on the primary demand for whisky in Italy. In contrast to previous works, this issue is investigated in a multivariate framework by referring to Johansen's cointegration technique; this choice allows the non-stationary dynamics of aggregate marketing data to be taken into account, as well as their short-term and long-term relationships. Even if advertising is linked to real prices and sales in the long run, our analysis reveals no evidence supporting the effectiveness of advertising on the aggregate demand for whisky, which is essentially determined by the real price, both in the short and the long term.     

Balanced growth and structural breaks: evidence for Germany

One of the central hypotheses of the neoclassical growth literature is the balanced-growth hypothesis, which predicts that output, consumption and investment grow at the same rate. Empirically, this implies that the consumption-to-output ratio and the investment-to-output ratio must be stationary and that consumption and investment must be cointegrated with output. This article tests these implications with respect to Germany, using unit root tests and cointegration techniques that allow for an endogenously determined structural break. We find that the long-run growth path of the German economy is consistent with the balanced-growth hypothesis if we allow for a structural break associated with the worldwide productivity slowdown of the early 1970s.     

The effects of imperfect auditing on managerial compensation

We study the optimal shareholder–manager contract having the property to induce the manager to exert high effort and truthfully reveal firm performance. This contract design problem is solved under the assumption of imperfect auditing, either because of mistakes or because of collusion between managers and auditors. The imperfection of the audit technology is costless up to a threshold, beyond which it causes a distortion in the incentive compatible contract or even prevents its existence. This result may help explain the observed decline in the use of stock options, tracing it back to an unfocused activity or poor performance of auditors.     

Real business cycle models of the Great Depression

The Great Depression of the 1930s is again on the frontier of research in macroeconomics. Researchers working in the real business cycle (RBC) tradition have recently started to apply their theoretical apparatus to the event. This paper discusses the result of their work and assesses the role of history and macroeconomics in analysing the Great Depression. I argue that the breaking of the depression taboo in macroeconomics has been a desirable completion of the cliometric revolution: no historical event should be exempt from a dispassionate quantitative analysis. On the other hand, the substantive contribution of RBC models is not yet sufficient to establish a new historiography of the Great Depression.     

PUBLIC EDUCATION, FERTILITY INCENTIVES, NEOCLASSICAL ECONOMIC GROWTH AND WELFARE

Using a simple overlapping generations model of neoclassical growth, we analyse the effects of both child allowances and the system of public education on the rate of fertility, the per capita income and the individual lifetime welfare. The essential message of the present paper is that developed countries plagued by below-replacement fertility and income stagnation may raise per capita income and the rate of fertility at the same time by increasing the public education expenditure rather than by resorting to child allowances. The latter, in fact, are found to be harmful for long-run neoclassical economic growth and, in contrast with the common belief, for the rate of population growth as well. Moreover, welfare analysis has shown the existence of a Pareto-efficient welfare-maximizing educational contribution rate.
