On the dynamics of an inflation IS‐LM model

The aim of the present paper is to analyze the dynamic of a generalized IS‐LM macroeconomic model for the inflation via the use of the averaging theory of dynamical systems. For this 3‐dimensional system we present a rigorous proof on the existence of a limit cycle in the case of considering a nonlinear action of cubic type on the real net product. Moreover we study the stability and the Hopf bifurcations of the system equilibria for different values of the parameters.     

BEHAVIORAL ECONOMICS AND BEHAVIORAL FINANCE: A BIBLIOMETRIC ANALYSIS OF THE SCIENTIFIC FIELDS

The aim of the study is to conduct a bibliometric analysis of the scientific field of Behavioral Economics and Behavioral Finance. The research was conducted using the Web of Science database, which returned 2617 articles, revealing that the amount of research within these fields has grown over time. Furthermore, the results also prove the relevance of the works of Daniel Kahneman and Amos Tversky for the field of Behavioral Economics and Finance, and Steven Hursh to Behavioral Economics. It is still possible to note that the field of Behavioral Economics encompasses subjects that connect human behavior with demand, consumption and price, with investments and with managerial decisions, as well as with the role played by heuristics and cognitive biases in decision‐making processes. In turn, the field of Behavioral Finance is more focused on the study of errors of judgment and of decision‐making characteristics in financial investments. Additionally, it is inferred that the field of Behavioral Economics is more wide‐ranging than the field of Behavioral Finance, as the latter is a byproduct of Behavioral Economics. Finally, a conclusion is then reached, demonstrating that the fields of Behavioral Economics and Finance have turned into an important field of study.     

Option pricing when correlations are stochastic: an analytical framework

In this paper we develop a novel market model where asset variances–covariances evolve stochastically. In addition shocks on asset return dynamics are assumed to be linearly correlated with shocks driving the variance–covariance matrix. Analytical tractability is preserved since the model is linear-affine and the conditional characteristic function can be determined explicitly. Quite remarkably, the model provides prices for vanilla options consistent with observed smile and skew effects, while making it possible to detect and quantify the correlation risk in multiple-asset derivatives like basket options. In particular, it can reproduce and quantify the asymmetric conditional correlations observed on historical data for equity markets. As an illustrative example, we provide explicit pricing formulas for rainbow “Best-of” options.     

The role of networking in the competitiveness of firms

Two main forces characterise production systems today: on the one hand, the increasingly global nature of markets and economies has resulted in increasing competition and a new, more global division of labour. On the other, the greater complexity of technology makes innovation a key aspect in the competitiveness of manufacturing firms. The establishment of cooperative networks seems to be important in both processes. This paper aims to explore these aspects by analysing the competitiveness of firms in four different sectors of the manufacturing industry: food, chemicals, electronics and vehicles. Data have been obtained from a survey conducted specifically for this purpose at company level in Spain. Findings from the empirical analysis, based on the application of the Polytomous Logistic Universal Model (PLUM), confirm the positive effects that the ability to network has on company performance. In particular, among all the potential organisations that work as partners of the firms, the paper shows the importance of intra-firm cooperation, the user-producer relationships and the cooperation between competitors.

ISO 14001 and CO2 emissions: An analysis of the contingent role of country features

This study explores whether the association between the aggregate level of ISO 14001 adoption in a country and the reduction of its CO₂ emissions differs across national settings. We analyze potential variations in three country features: intensity of competition, inclination of firms to behave ethically, and the importance that firms attach to relationships with stakeholders. Based on a sample of 53 countries for the period 2007–2017, our results show that the connection between the aggregate level of ISO 14001 adoption and lower levels of CO₂ emissions is stronger in countries where firms tend to behave ethically but is weaker in countries where there is intense competition or where firms place high emphasis on relationships with stakeholders. These findings expand our understanding about the macrolevel consequences of ISO 14001 adoption.     

A Minskyan account of emerging currencies dynamics

Abstract

The currencies of a few emerging market economies (EMEs) have been following a specific dynamic since the early 2000s: They are strongly subordinated to international financial conditions, appreciating in moments of tranquility and presenting sharp depreciations in peaks of uncertainty. What is the mechanism behind it? To answer this question, this article applies the Minskyan framework to the context of money managers and their portfolio allocation decisions. The approach provides a detailed account of the mechanisms of the appreciation phase, thus complementing the emerging currencies’ literature that is focused on crisis episodes. The result is a dynamic characterized by deviation-amplifying systems—the opposite of the mainstream view where fundamentals lead to an equilibrium-seeking mechanism. Apart from these contributions to the exchange rate literature, it enriches the Minskyan literature for providing a broader reading of the original framework that allows it to be transposed to a larger set of contexts and for identifying the main elements to be translated in an analysis of a different context.     

Variance and skew risk premiums for the volatility market: The VIX evidence

We extract variance and skew risk premiums from volatility derivatives in a model-free way and analyze their relationships along with volatility index and equity index returns. These risk premiums can be synthesized through option trading strategies. Using a time series of option prices on the VIX, we find that variance swap excess return can be partially explained by volatility index and equity index excess returns while these latter variables carry little information for the skew swap excess return. The results sharply contrast with those obtained for the equity index option market underlining very specific characteristics of the volatility derivative market.
