Financial innovation and demand for money: some empirical evidence

Recent criticism of money growth targets has been based on the implications of spreading financial innovation, since the latter has been considered to undermine monetary policy effectiveness both by bringing about an increase in the interest elasticity of money demand and by producing instability of the money demand function. The empirical results presented in this paper – focusing on a single and specific case of financial innovation particularly suited to study the isssue at stake – falsify both hypotheses.     

A discussion of the market and policy failures associated with the adoption of herbicide-tolerant crops

Weed control in the U.S. Midwest has become increasingly herbicide-centric due to the adoption of herbicide-tolerant (HT) crops in the 1990s. That integrated weed management (IWM) practices, including ecological and mechanical controls, are scarcely used is concerning. IWM would be a more sustainable form of farming for two reasons. First, it would reduce the negative health and environmental externalities associated with herbicide use. Second, it would reduce the selection pressure on weed populations and the development of weed resistance to some herbicides, thereby reducing the uncertainty of the long-term effectiveness of herbicidal weed control. In this context, we develop an economic framework to clarify the interplay among the different market failures that either contribute to the herbicidal ‘lock-in’ or make it problematic. We then analyse the evidence for and perceptions of these market failures based on twenty-four semi-structured interviews with farmers and experts conducted in 2017, as well as on discussions in the academic literature. To this end, we put into perspective the possible self-reinforcing effects in the adoption path of HT crops, such as increasing farm size, changes in farm equipment, increasing incentives for simplified crop rotations, and the loss of practical knowledge of IWM practices.     

Exchange Rate Regimes and Reserve Policy: The Italian Lira, 1883–1911

The three exchange rate regimes adopted by Italy from 1883 up to the eve of World War I — the gold standard (1883–1893), floating rates (1894–1902), and “gold shadowing” (1903–1911)—produced a puzzling result: formal adherence to the gold standard ended in failure while shadowing the gold standard proved very successful. This paper discusses the main policies underlying Italy’s performance particularly focusing on the strategy of reserve accumulation. It presents a cointegration analysis identifying a distinct co-movement between exchange rate, reserves, and banknotes that holds over the three sub-periods of the sample. Given this long-run relationship, the different performance in each regime is explained by the diversity of policy measures, reflected in the different variables adjusting the system in the various regimes. Italy’s variegated experience during the gold standard provides a valuable lesson about current developments in the international scenario, showing the central role of fundamentals and consistent policies.     

Single and joint default in a structural model with purely discontinuous asset prices

Structural models of credit risk are known to present both vanishing spreads at very short maturities and a poor spread fit over longer maturities. The former shortcoming, which is due to the diffusive behaviour assumed for asset values, can be circumvented by considering discontinuous asset prices. In this paper the authors resort to a pure jump process of the Variance-Gamma type. First the authors calibrate the corresponding Merton type structural model to single-name data for the DJ CDX.NA.IG and CDX.NA.HY components. By so doing, they show that it also circumvents the diffusive structural models difficulties over longer horizons. Particularly, it corrects for the underprediction of low-risk spreads and the overprediction of high-risk ones. Then the authors extend the model to joint default, resorting to a recent formulation of the VG multivariate model and without superimposing a copula choice. They fit default correlation for a sample of CDX.NA names, using equity correlation. The main advantage of our joint model, with respect to the existing non-diffusive ones, is that it allows full calibration without the equicorrelation assumption, but still in a parsimonious way. As an example of the default assessments which the calibrated model can provide, the authors price an FtD swap.

The role of ownership structure in integrated reporting policies

Integrated reporting (IR) is used to demonstrate a firm's capacity to create value in the short, medium, and long term. It can better represent existing relationships between the company and its stakeholders, with a particular focus on investors. Attention to IR has grown considerably in recent years. However, studies on the determinants of IR quality are still limited. This study aims to bridge this literature gap by being the first study to analyse the role of ownership structure in IR context. To this end, it uses agency theory and is based on a sample of 152 international companies that have adopted IR. The results indicate a positive effect of institutional ownership and a negative effect of ownership concentration, managerial ownership and state ownership on the quality of integrated reports. These results are also consistent with the level of alignment of integrated reports with the <IR> framework. To our knowledge, this is the first study that analyses the role of ownership structure in the IR policies.     

DETECTING AND ANALYZING THE EFFECTS OF TIME-VARYING PARAMETERS IN DSGE MODELS

We study how structural parameter variations affect the decision rules and economic inference. We provide diagnostics to detect parameter variations and to ascertain whether they are exogenous or endogenous. A constant parameter model poorly approximates a time-varying data generating process (DGP), except in a handful of relevant cases. Linear approximations do not produce time-varying decision rules; higher-order approximations can do this only if parameter disturbances are treated as decision rule coefficients. Structural responses are time invariant regardless of order of approximation. Adding endogenous variations to the parameter controlling leverage in Gertler and Karadi's model substantially improves the fit of the model.     

New development: Managing the Covid-19 pandemic—from a hospital-centred model of care to a community co-production approach

ABSTRACT

Covid-19 is not only a crisis of intensive care but a social and humanitarian crisis. Until mass vaccination is undertaken, control of contagion will rely on responsible behaviour by citizens. Strategies for fighting Covid-19 in different regions of Italy have shown that an area-specific approach, not just hospital-focused, pays off. This article proposes a community co-production approach, in the light of discussions with politicians and key health decision-makers and actors.     

Influential listeners: An experiment on persuasion bias in social networks

This paper presents an experimental investigation of persuasion bias, a form of bounded rationality whereby agents communicating through a social network are unable to account for repetitions in the information they receive. We find that, after repeated communication within a social network, social influence depends not only on being listened to by many others, but also on listening to many others. We show that persuasion bias can be viewed as an extreme case of a generalized boundedly rational updating rule in which agents receive more or less attention depending on how many other agents they listen to. The results indicate that behavior in the experiment is consistent with an updating rule according to which agents' social influence is proportional to their indegree.
