SCALE ECONOMIES AND HETEROGENEITY IN BUSINESS MONEY DEMAND: THE ITALIAN EXPERIENCE

This paper investigates the demand for money by firms and the existence of economies of scale in the Italian manufacturing industry. We estimate a model for cash elaborated by Fujiki and Mulligan using a different estimation procedure from the previous literature. We then introduce an iterative procedure based on backward exclusion of firms from model estimation which points out the high heterogeneity of Italian companies in money demand. Our estimates show that the Italian manufacturing industry, considered as a whole, does not enjoy scale economies in money demand. However, our iterative procedure points out that the cause of this result has to be ascribed to small firms which are characterized by thin cash money holdings and a consequent very modest opportunity cost.     

HUMAN CAPITAL MEASUREMENT: A SURVEY

Abstract After a short history of the concept of human capital (henceforth HC) in economic thought ( Section 1 ), this study presents the two main methods for estimating the value of the stock of HC – the retrospective and prospective one – with a review of the models proposed ( Section 2 ). These methods are linked both to the theory of HC investment as a rational choice ( Section 3 ), the literature analysing the contribution of HC investment to economic growth and the HC estimating method through educational attainment ( Section 4 ). The more recent literature on HC as a latent variable is also assessed ( Section 5 ) and a new method of estimation where HC is seen both as an unknown function of formative indicators and as a ‘latent effect’ underlying earned income is proposed ( Section 6 ). Section 7 concludes.     

Is the 2008 financial turmoil increasing the risk of a bank run？ An empirical research in Geneva

In this paper, the authors present the results of an empirical study that attempts to analyse the risk of bank run in Geneva, Switzerland. Two similar surveys have been conducted upon two independent samples of Geneva population （June 2008 and February 2009） to detect the existence of predictive signals leading to a bank run within the selected area. The authors discover that Geneva inhabitants are generally confident in Swiss banks; the risk of a bank run in the area is low. However, reliance to the national banking system is worsening： The number of people fearing about their savings and those thinking the default of a major Swiss bank as ＂possible＂ has significantly risen. Also, more and more people keep updated about the current financial crisis; overall trust in Swiss banks has slightly decreased.     

A note on contribution games with loss functions

Decisions on joint funding of continuous public goods between two agents often involve heterogeneous targets. We introduce loss functions in a contribution game in order to study the effect of this conflict. Unlike Varian (1994), joint contribution occurs only if the players’ targets are sufficiently close and the sequential game reduces free riding problems, while total contribution is higher in the simultaneous game.     

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.     

RETHINKING ENDOGENOUS MONEY: A CONSTRUCTIVE INTERPRETATION OF THE DEBATE BETWEEN HORIZONTALISTS AND STRUCTURALISTS

Beyond a widespread agreement on the idea that ‘loans create deposits’ and ‘deposits make reserves’, there is much controversy in the endogenous money literature over the workings of the reserve market, the credit market and the financial markets. In this paper a constructive interpretation of the debate between horizontalists and structuralists is suggested and their arguments are taken forward by showing that these controversial issues can be explained rigorously once a single‐period–continuation framework is adopted.     

Hicks on monetary theory and history: money as endogenous money

Hicks was never tired of saying that monetary theory is in history.What he meant was that monetary theory is intrinsically relatedto real events, and more importantly that monetary issues needto be analysed in a dynamic sequential context in which timeplays an essential part. He went on developing a particularsequential analysis: the study of what happens within a singleperiod (‘single-period theory’) and the study ofthe linkages between a succession of those periods (‘continuationtheory’). It is suggested that this distinction providesa useful lesson for modern endogenous money theorists.     

THE COMPLEX DYNAMICS OF THE SIMPLE RICARDIAN SYSTEM: A NOTE

In a recent note, Bhaduri and Harris (1987) showed that a discrete-time dynamic version of the ‘simple’Ricardian system (i.e. Blaug's (1978) popular version of Kaldor's (1955-6) representation of Ricardian distribution theory, which includes linear agricultural productivity) can be endowed with an unstable stationary state, and that the system can also exhibit “chaotic” orbits (cfr. Collet and Eckmann, 1980), even if these phenomena cannot appear when the adjustment process is continuous. This stationary state does not necessarily have to be unstable. A slightly generalized version of the ‘simple’Ricardian system (we dispense with the linearity assumption) is used in this paper to analyse a number of meaningful special cases in which the stationary state is stable.     

Occupational and Job Mobility in the US*

We propose a new methodology to measure worker mobility across occupations and jobs in the US, building on the limited longitudinal dimension of monthly CPS data. For the period 1979–2006, we find that about 3.5% of male workers employed in two consecutive months report different three‐digit occupations. This rate is procyclical, mildly rising in the 1980s and falling after 1995. We also revise upward current estimates of aggregate job‐to‐job mobility since 1994, from 2.7% to 3.2% of employment per month. Despite extreme similarity of average levels and time‐series behavior, occupational and job mobility are only weakly correlated.
