Disequilibrium models due to a “learning by doing” process

Sommario Si considerino fluttuazioni e crescita in un modello neo-keynesiano in tre diverse ipotesi macroeconomiche, che danno origine a diversi modelli matematici in tempo discreto, o mappe. In particolare si analizza un modello di crescita bidimensionale, rappresentato da un endomorfismo lineare a tratti. Separando il comportamento dinamico delle pendenze di rette che escono dall'origine, dalla dinamica dei punti su tali rette, si mostra che il comportamento dinamico del modello è governato dalla dinamica di un endomorfismo unidimensionale. Ciò semplifica lo studio dei valori di biforcazione che creano rette invarianti, su cui le traiettorie sono divergenti, e consente di determinare il bacino di attrazione di regioni assorbenti che contengono i cammini di crescita, regolari o caotici.

Fluctuations and growth in a new-keynesian model are considered in three different macroeconomic assumptions, giving rise to different mathematical models in discrete time, or maps. In particular a two-dimensional growth model represented by a piecewise linear endomorphism is analysed. Separating the dynamics of the slopes of straight lines issuing from the origin, from those of the points on these lines, it is shown that the dynamics of the model are governed by the dynamics of a one-dimensional endomorphism. This simplifies the study of the bifurcation values which create invariant lines on which the trajectories are divergent, and enable us to determine the basin of attraction of the absorbing region which includes regular or chaotic growth paths.

A model of growth with inherited tastes

This research aims at studying a general equilibrium closed economy with overlapping generations and inherited tastes (aspirations), as in de la Croix (Econ Lett 53(1):89–96, 1996). It shows that the interaction between the intensity of aspirations and the elasticity of substitution of effective consumption affects the qualitative and quantitative long-term dynamics from both local and global perspectives. The related literature is extended by showing that (1) the Neimark–Sacker bifurcation found by de la Croix (1996) does not necessarily give rise to fluctuations and (2) endogenous (long-lasting) fluctuations occur through the emergence of period-doubling bifurcations.     

Cooperation with a multiproduct corporation in a strategic managerial delegation

We consider an industry composed of a multiproduct corporation that adopts corporate social responsibility (CSR) as a strategic managerial delegation and examine the profit-incentive to form a cooperative group. We find that competition is an equilibrium for any degree of substitutability and yields the highest CSR, which is increasing in the degree of substitutability. We also show that full cooperation is an equilibrium for lower substitutability but induces no CSR, whereas partial cooperation with one uniplant firm is an equilibrium for higher substitutability but yields lower CSR than that under competition. Therefore, cooperation might reduce strategic CSR activities, whereas competition will encourage higher CSR but yield lower industry profits.     

Suspending disbelief: Influencing engagement in scenarios of forest futures

Scenario analysis is an approach to long-term planning that informs decision-making in contexts of highly uncertain future conditions. Scenario-based studies are rapidly growing in popularity, yet many aspects of the method are not fully understood. Participants' willingness to suspend disbelief in possible futures is an integral component of scenario-based studies, essential for considering alternative future scenarios, yet little is known about the factors that affect it. Participation in a scenario project does not necessarily imply willingness or ability to suspend disbelief; participants may not suspend disbelief simply upon request. However, the scenario literature says little about the aspects of scenario-based studies that influence suspension of disbelief.This article explores the factors that influenced the suspension of disbelief in one scenario exercise about the future of Canada's forests. Participants differed in their abilities to suspend disbelief in the scenarios in part because of their past experiences and expertise in particular areas, and their assessments of probable and desired future outcomes. Elements of the project design and implementation influenced participants' abilities to engage the scenarios. The results have implications for those interested in using scenarios for helping people and communities envision possible - and sustainable - futures.     

Brazilian OFDI Determinants

Recently, the global economy assumed a new setting in which emerging economies began to make substantial investments in the international market. This study aimed to investigate the determinants of outward foreign direct investment from Brazil from 2002–2011. The proposed models developed included attractiveness of the host country, characteristics of home country, and firms’ strategies. The results corroborate the existing argumentations concerning adaptation of mainstream theory with respect to the realities of emerging economies. Brazilian multinationals do not internationalize their activities in pursuit of cost reduction, efficiency, or to explore new markets or natural resources of the host countries. Results show that Brazilian investments were attracted by the availability of skilled labor, openness of the host market, geographic proximity, improved financial conditions of Brazilian companies, and national companies’ strategy of reaffirmation and consolidation as global players.     

Cross-Border Shopping: A Survey

The aim of this paper is to undertake a review of the most important literature on the phenomenon of fiscally induced cross-border shopping. Following the presentation of the principal theoretical models, the study concentrates on applied literature. Firstly, the elements common to the diverse applications are described, and then, a detailed analysis of the research undertaken into cross-border shopping for alcoholic drinks, tobacco, fuel, and lotteries is provided, concluding with a reference to the interaction between cross-border purchases and those effected over the internet. The results achieved by the empirical research coincide and support the principal result of the theoretical literature: the tax differentials between neighboring territories induce consumers to purchase in the territory where taxation is lower, on the condition that the tax saving compensates for the transport costs associated with the travel made by the purchaser in order to take advantage of the lower taxation.     

The impact of European firms＇ economic conditions and financial performance on accounting quality

In this study the authors analyse the possible effect of firms＇ economic conditions and financial performance on accounting quality. Bradshaw, et al. （2004）, Gelos ＆ WEI （2005） stated that financial reporting quality is fundamental for investors and it affects international capital movements. Following Schipper ＆ Vicent （2003）, the authors estimated accounting quality by abnormal accruals and earnings persistence. The authors＇ contribution consists of investigating a huge number of firms from 17 European countries using unbalanced panel data. The authors found evidence that economic conditions affect accounting quality： big firms and those with high current earnings exhibit better financial information. These results are robust because they do not depend on the accounting quality proxy, even when the authors estimated regression with economical and financial factors alone or together. Financial performance does not seem to affect accounting quality. However, this relation is not linear because in high leveraged firms, the capital structure becomes determinant.     

How the Perceptions of Five Dimensions of Corporate Citizenship and Their Inter-Inconsistencies Predict Affective Commitment

Through a convenience sample of 260 employees, the study shows how employees’ perceptions about corporate citizenship (CC) predict their affective commitment. The study was carried out in Portugal, a high in-group and low societal collectivistic culture. Maignan et al.’s (1999, Journal of the Academy of Marketing Science 27(4), 455–469) construct, including economic, legal, ethical, and discretionary responsibilities was used. The main findings are: (a) contrary to what has been presumed in the literature, the discretionary dimension includes two factors: CC toward employees and toward community; (b) perceptions of CC explain 35% of unique variance of affective commitment; (c) the best predictors are perceptions of economic and legal CC and, mainly, perceptions of discretionary CC toward employees; (d) the perceptions of discretionary CC toward employees are significantly better predictors of affective commitment than are perceptions of economic, ethical, and discretionary CC toward the community; (e) perceived inconsistency of the several CC dimensions is detrimental to employees’ affective commitment. The study questions the four-dimensional model of the CC construct as operationalized by Maignan et al., suggests that culture should be included as a moderating variable in future research, and stresses that affective commitment may decrease when employees perceive that their organizations act upon the several areas of CC inconsistently.     

Fiscal multipliers in the Eurozone: an SVAR analysis

We compute the value of fiscal multipliers (for government primary expenditure, Income and wealth taxes and for Production and import taxes) in the Eurozone countries since the creation of the currency union (2000Q1-2016Q4), in order to understand how the values can vary according to the public debt level, the pace of economic growth, and the output gap. Imposing quarterly fiscal shocks, the results showed that government expenditure had a positive effect on output, with an annual accumulated multiplier of 0.44, whereas tax multipliers presented negative signs: the Income and wealth and the Production and import taxes stood at ?0.11 and ?0.55, respectively. Furthermore, the spending multiplier showed a higher value for countries with lower levels of public debt, during recessions, and in countries with negative output gaps. On the other hand, tax shocks seemed to be recessive in highly indebted countries and those facing positive output gaps.     

Mergers and Acquisitions and Market Volatility of Brazilian Banking Stocks: An Application of GARCH Models

The main objective of this research was to investigate the impacts caused by announcements of mergers and acquisitions (M&As) on the volatility of the returns of Brazilian bank stocks from 1994 to 2015. In order to achieve the proposed objective, this study applied Generalized Autoregressive Conditional Heteroscedastic (GARCH) class models to the series to model their volatility. Our results confirmed the impact of the announcement of M&As on volatility. They suggest that M&A announcements are expected to cause a negative reaction if related to an expansion or a deal involving a less-well known bank, and a positive reaction if it involves well-known bank with good reputation—a higher level of confidence and a lower level of information asymmetry for investors.
