Are they telling the truth? Revealing hidden traits of satisfaction with a public bike-sharing service

Public bike-sharing systems (BSSs) are an emerging mode of transportation introduced by municipalities to solve congestion problems in metropolitan areas, especially when integrated with other types of transportation. In the last years, the number of public bike-sharing services has been constantly on the rise all over the world, and generally the overall satisfaction with them is high. However, satisfaction with public services is driven by mechanisms that can differ from those in the private sector. It is important to establish to what extent a high satisfaction is genuine or simply ephemeral. Even “old” public services (like public transportation) become “gold” when accompanied by the introduction of new technologies. In this paper we analyze this phenomenon using data from a satisfaction web-survey conducted among customers of the public BSS “BikeMi” in Milan, Italy, in a period when mobile technologies have been introduced to speed up the service. On analyzing the responses to satisfaction questions using simple summary statistics, the level of satisfaction resulted very high. However, our aim was to look for potential “darker” sides of the service by detecting possible hidden satisfaction components. For this purpose, we used the Nonlinear Principal Components Analysis, which is particularly powerful in this context. A simple textual analysis was also performed as a validating test. Results from our analysis indicated that satisfaction is flawed by a set of factors like the mechanics of the bikes, the picking and dropping system, and the apps used to organize the service. Less concern was detected for more general aspects of the service.     

Great Recession and Macroeconomic Theory: A Useless Crisis?

ABSTRACT

The global financial crisis of 2007–08 and the subsequent Great Recession have pushed many economists to acknowledge a fundamental limit in the theoretical models elaborated after the monetarist counter-revolution: these models disregard the financial system. The years following the Great Recession have thus been marked by the development of what can be called the ‘Financial Frictions Approach’, a theoretical approach based on the addition of the financial system to the New Keynesian DSGE model. The results of this line of research are beginning to appear also in macroeconomics textbooks. Significant examples are the publication of the seventh edition of Blanchard’s textbook, and the publication of the third edition of the textbook co-authored by Blanchard, Amighini and Giavazzi. The objective of this work is twofold: (i) to show that the new model presented by Blanchard, Amighini and Giavazzi, which reflects the results of the ‘Financial Frictions Approach’, does not allow to elaborate a coherent explanation of the Great Recession and (ii) to present the pillars of an alternative theoretical model based on the lessons of Keynes, Schumpeter and Minsky.     

The international risk sharing puzzle is at business cycle and lower frequency

Abstract We decompose the correlation between relative consumption and the real exchange rate in its dynamic components at different frequencies. Using multivariate spectral analysis techniques, we show that, at odds with a high degree of risk sharing, in most OECD countries the dynamic correlation tends to be quite negative, and significantly so, at frequencies lower than two years – the appropriate frequencies for assessing the performance of international business cycle models. Theoretically, we show that the dynamic correlation over different frequencies predicted by standard open economy models is the sum of two terms: a term constant across frequencies, which can be negative when uninsurable risk is large; a term variable across frequencies, which in bond economies is necessarily positive, reflecting the insurance intertemporal trade provides against forecastable contingencies. Numerical analysis suggests that leading mechanisms proposed by the literature to account for the puzzle are consistent with the evidence across the spectrum.

The Inflationary Consequences of a Currency Changeover on the Catering Sector: Evidence from the Michelin Red Guide*

This paper examines the inflationary consequences of a currency changeover in the catering market. Empirical evidence from the Michelin Red Guide shows that: (i) differently from restaurants in non‐euro countries, restaurants in the euro area experienced abnormal price increases just after the changeover; and (ii) among restaurants in the euro area, tourist restaurants are responsible for most of the abnormal price increases. These results suggest that proposed explanations for the changeover effect, such as menu adjustment and rounding up, are only part of the story. We present a simple model of the catering market that is consistent with the evidence.     

Estimating deferred taxation on dividends in business groups

In a group of companies corporate income taxation is levied on basic earnings and then on dividends paid to holding companies. The entity of this taxation depends on the tax regime, so that income may be taxed twice, first in the hands of the subsidiaries, then in the next years in the hands of holding companies. Therefore, consolidated profits may not be wholly paid to shareholders (who are the ultimate owners) and deferred taxes have to be computed in order to determine the true profitability of a group of companies. Using input–output theory, we developed a framework to estimate deferred taxation on dividends in business groups. Such relationships can be particularly useful when cross‐shareholdings exist to determine deferred liabilities under several accounting standards. Copyright © 2000 John Wiley & Sons, Ltd.     

Finance and development: Is Schumpeter’s analysis still relevant?

In recent years, numerous studies have been published highlighting the role of financial structures in the development process of contemporary economies. In these recent studies, there is always a reference to the pioneering work of Schumpeter; in particular in the writings of Rajan and Zingales [Rajan, R., Zingales, L. 2003a. Banks and markets: The changing character of european finance, NBER Working Paper Series, No. 9595, March; Rajan, R., Zingales, L. 2003b. The great reversal: The politics of financial development in the twentieth century, Journal of Financial Economics 69, 5–50; Rajan, R., Zingales, L. 2003c. Saving Capitalism from Capitalist, Crown Business Division of Random House, New York], important elements of Schumpeter’s theoretical framework are used. These works afford us an interesting opportunity to re-evaluate the importance of Schumpeter’s contribution. The thesis put forward in this paper is that while they do indeed highlight important elements of Schumpeter’s theory, Rajan and Zingales do not take the implications thereof into account and, furthermore, they neglect certain fundamental aspects of the Schumpeterian analysis that are closely connected with the parts that they consider. This renders their work incomplete, and prevents their analysis from achieving the coherence of Schumpeter’s theory.     

Productivity, terms of trade and the ‘home market effect’

This paper analyzes the international transmission and welfare implications of productivity gains and changes in market size when macroeconomic adjustment occurs both along the intensive margin of trade (changes in the relative price of existing varieties of tradable goods) and the extensive margin (creation and destruction of varieties). We draw a distinction between productivity gains that enhance manufacturing efficiency and gains that lower the cost of firms' entry and of product differentiation. Countries with lower manufacturing costs have higher GDP but supply their products at lower international prices. Instead, countries with lower entry costs supply a larger array of goods at improved terms of trade. Output growth driven by demographic expansions, as well as government spending, is associated with an improvement in international relative prices and firms' entry. While trade liberalization may result in a smaller array of goods available to consumers, efficiency gains from deeper economic integration benefit consumers via lower goods prices. The international transmission mechanism and the welfare spillovers vary under different asset market structures, depending on trade costs, the elasticity of labor supply, and consumers' taste for varieties.
