FROM INPUT–OUTPUT TABLES TO SUPPLY-AND-USE TABLES

In 1991, Statistics Netherlands introduced the supply-and-use tables as part of the national accounts. Since then, the supply-and-use tables have been the main statistics on the production structure of the Dutch economy. They form the basis from which input–output tables are derived. The time series of supply-and-use tables starts in 1987. However, there is a need for a time series since 1970 because benchmark revisions of the Dutch national accounts would become far easier if such time series were available. Therefore, a method has been developed to derive supply-and-use tables from existing input–output tables. This article presents the algorithm.     

An Average-Based Accounting Approach to Capital Asset Investments: The Case of Project Finance

Literature and textbooks on capital budgeting endorse net present value (NPV) and generally treat accounting rates of return as not being reliable tools. This paper shows that accounting numbers can be reconciled with NPV and fruitfully employed in real-life applications. Focusing on project finance transactions, an average return on investment (AROI) is drawn from the pro forma financial statements, obtained as the ratio of aggregate income to aggregate book value. We show that such a metric correctly captures a project's economic profitability, as long as it is compared with a comprehensive weighted average cost of capital (WACC) that includes a correction factor that takes account of the capital foregone by the investors. In contrast to the internal rate of return, AROI is unique, and we provide an explicit functional relation that links it to the NPV. The approach holds for levered and unlevered projects, constant and non-constant leverage ratios, and constant and non-constant WACCs.     

Stochastic models of resonating markets

This paper describes a way to model a seasonally and irregularly peaking price dynamics, as that originated in commodity and energy markets, using a system of coupled nonlinear stochastic differential equations. The specific case of an electric power market is used to show which microeconomic features this approach is able to model. Critical point analysis is used in a simple way to show how the interaction between dynamic criticality and stochasticity can be used to develop further models, useful to explore more deeply other types of peaking price dynamics.     

Deficits, Money Growth and Inflation in Italy: 1875–1994

In this paper, we examine econometrically the "fiscal dominance" model of the Monetary History of Italy proposed by Spinelli and Fratianni (1996). We test the proposition that monetary policy is endogenous to fiscal policy, and that such an endogeneity creates a specificity in the process generating Italian inflation. We perform our econometric tests by estimating a small structural linear econometric model, addressing carefully the issues of data-congruency of the specification, non-stationarity, cointegration, and credibility of the over-identifying restrictions. Our econometric investigation is based on a sample of annual observations from 1875–1994 and exploits the structural break which occurred in 1975, when Baffi became Governor of the Bank of Italy and the lack of independence of the central bank was first perceived as a problem. Baffi started the slow evolution process leading to the independence of the central bank, which was institutionally ratified by his successor Ciampi, when, in 1981, the Bank of Italy interrupted his commitment to buy all the government bonds left unsold in the public tenders (the "divorce"). Our empirical analysis over the sample 1875–1975 confirms the existence of a link between government deficit and money growth, and of a long-run relationship between the quantity of money and the price level; the evidence also stresses the relevance of supply side factors in the determination of inflation. When the model estimated for the sample 1875–1975 is applied to the period 1975–1994, a clear structural break in the relation between government deficits and money growth emerges.

Estimating Market Power with Weak A Priori Information: An Exploratory Approach to the Model-Specification Problem

Choosing the wrong theoretical model to describe an industry??s behavior may lead to biased estimates of the degree of market power. This paper presents a two-step, data-driven methodology to reduce the risk of mis-specification bias. In the first step, a sliced inverse regression identifies the significant factors that affect the industry??s pricing behavior. In the second step, a non-parametric regression of price on the SIR factors estimates the link functions. The output of the algorithm offers useful information to identify the model that best approximates the industry??s pricing behavior. In addition, the output of the algorithm is used to develop a post-estimation test for model specification.     

The notion of private information in a modern perspective: a reappraisal of Hayek's contribution

Hayek's critical attitude towards Walrasian modelling was based on informational considerations. In his view, a meaningful notion of equilbrium has to deal with the consistency of agents' plans which information is dispersed throughout the economy. He emphasized that only in this context could the role of market prices as aggregators of information be correctly analysed. Recent developments in general equilbrium theory with rational expectations have taken up the issue formally. In this paper, Haek's main ideas about the competiitive mechanism are compared with these recent results. It is argued that Hayek's notion of private information is different from that used in modern equilibrium theory, not only because of its dynamic content, as many critics observed ex post, as is usually in a general equilibrium framework. This issue of whether modern notions of private information, namel that used in conract theory, are good substitutes for Hayek' notion of personal knowledge is also examined in detail. From this analysis, it is possible to conclude that Hayek's notion of equilibrium neither entails Pareto optimality prperties nor full informational efficiency.     

The high-frequency response of exchange rates to monetary policy actions and statements

This paper investigates the impact of US monetary policy on the level and volatility of exchange rates using an event study with intraday data for five currencies (the US dollar exchange rate versus the euro, the Canadian dollar, the British pound, the Swiss franc, and the Japanese yen). I construct two indicators of news about monetary policy stemming separately from policy decisions and from balance of risk statements. Estimation results show that both policy decisions and communication have economically large and highly significant effects on the exchange rates, with the surprise component of statements accounting for most of the explainable variation in exchange rate returns in response to monetary policy. This paper also shows that exchange rates tend to absorb FOMC monetary surprises within 30-40 min from the announcement release.     

Evaluating the effect of monetary policy on unemployment with alternative inflation forecasts

This paper explores the role that inflation forecasts play in the uncertainty surrounding the estimated effects of alternative monetary rules on unemployment dynamics in the euro area and the US. We use the inflation forecasts of 8 competing models in a standard Bayesian VAR to analyse the size and the timing of these effects, as well as to quantify the uncertainty relative to the different inflation models under two rules. The results suggest that model uncertainty can be a serious issue and strengthen the case for a policy strategy that takes into account several sources of information. We find that combining inflation forecasts from many models not only yields more accurate forecasts than those of any specific model, but also reduces the uncertainty associated with the real effects of policy decisions. These results are in line with the model-combination approach that central banks already follow when conceiving their strategy.     

Labor market intermediaries make the world smaller

This paper uses network analysis to study how employment intermediaries have influenced inter-firm worker mobility in a region of Italy, in response to a 1997 reform that introduced temporary employment agencies. Worker reallocations from a matched employer-employee dataset are mapped onto a directed graph where the vertices are firms and the links denote transfers of workers between firms. Temporary employment agencies significantly improve network integration and practicability, while rapidly increasing the control over mobility channels. The trade off inherent in intermediation activity is captured and discussed. The potential of network analysis as a tool for monitoring regional labor markets is highlighted.
