Estimating food demand in Paraguay from household survey data

We estimate a food demand system in Paraguay based on the 1997 national household survey, considering 12 food categories. To obtain demand elasticity estimates from household survey data accounting for quality effects, measurement errors, and censored observations, price indexes are obtained from ordinary least squares predictions of changes in unitary values caused by spatial and temporal variations, and the two‐step estimation procedure ( Shonkwiler and Yen, 1999 ) is applied. Our approach yields reasonable estimates of combined quantity and quality responses with respect to price. Results suggest distinct consumption behavior in urban and rural areas, particularly for chicken, eggs, dairy, and fats and oils, which are likely because of differences in the food distribution system and availability of nonmarket food sources.     

Renegotiation and Collusion in Organizations

It has been argued that collusion among the members of an organization may lead to inefficiencies and hence should be prevented in equilibrium. This paper shows that whenever the parties to an organization can renegotiate their incentive scheme after collusion, these inefficiencies can be greatly reduced. Moreover, it might not be possible to prevent collusion and renegotiation in equilibrium. Indeed, if collusion is observable but not verifiable, then the organization's optimal incentive scheme will always be renegotiated. If, instead, collusion is not observable to the principal, both collusion and renegotiation will occur in equilibrium with positive probability. The occurrence of collusion and renegotiation should therefore not be taken as evidence of the inefficiency of an organization.     

De-Amalgamation in Action: The Queensland experience

Abstract

While a substantial theoretical and empirical literature has examined compulsory local government consolidation, little is known about de-amalgamation after forced mergers. Following the controversial 2008 Queensland local government amalgamation programme, which saw a radical reduction in the number of local councils, four forcibly merged councils have finally begun to de-amalgamate following successful plebiscites. This paper traces the extraordinary Queensland de-amalgamation process from its inception and attempts to place it in a broader conceptual framework. The paper provides a critical assessment of Queensland de-amalgamation policy development and implementation and seeks to draw broader public policy lessons for structural reform in local government.     

Determinants shaping the international currency system: Where do currencies stand relative to their equilibria?

Using a sample of 27 currencies, we empirically test the role of a large set of determinants potentially underlying currencies' share in the international currency system, providing, to the best of our knowledge, the most comprehensive study of this kind so far. We propose a new global indicator that quantifies the international use of currencies on the basis of three dimensions—medium of exchange, unit of account and store of value. From a range of indicators including openness, financial development and institutional development indicators, we uncover several variables that are significant in explaining the international status of currencies, hence contributing to understanding the role of the determinants shaping the international currency system. We also investigate the long-run equilibrium values for currency shares, allowing us to score currencies on the basis of the potential stemming from the determinants. We contribute to the debate on international currencies' prospects, not only by looking at much discussed currencies such as the US dollar, the euro and the Chinese renminbi, but also by uncovering potential of emerging currencies. This knowledge is of the utmost importance for the debate on the reform of the international monetary system—from the point of view of academics, policymakers and market practitioners.     

A proposed enterprise risk management model for health organizations

Health care organizations are environments with high management complexity and subject to a constant exposure to risks. Enterprise risk management (ERM) has been studied and applied in different economic environments with the aim of improving organizational performance. However, the health sector still suffers from a lack of attention in this context, in particular with regard to the need for a high degree of financial transparency and for the establishment of process-orientated management, and this provides the motivation for the study described in this paper. An ERM model for health organizations is proposed, based on a systematic literature review and on seven case studies in Brazilian hospitals. An approach to economic risk assessment using indicators such as the cash flow at risk and the variability of costs and receipts from the proposed model is suggested. The health organizations involved in the case studies all interpret ERM as a source of information contributing to corporate governance, and the indicators listed provide constructive data for improvement-driven decision-making. Given the interest expressed by the organizations involved, further application and validation of the proposed model in subsequent studies is suggested.     

Forward-looking portfolio selection with multivariate non-Gaussian models

In this study, we suggest a portfolio selection framework based on time series of stock log-returns, option-implied information, and multivariate non-Gaussian processes. We empirically assess a multivariate extension of the normal tempered stable (NTS) model and of the generalized hyperbolic (GH) one by implementing an estimation method that simultaneously calibrates the multivariate time series of log-returns and, for each margin, the univariate observed one-month implied volatility smile. To extract option-implied information, the connection between the historical measure P and the risk-neutral measure Q, needed to price options, is provided by the multivariate Esscher transform. The method is applied to fit a 50-dimensional series of stock returns, to evaluate widely known portfolio risk measures and to perform a forward-looking portfolio selection analysis. The proposed models are able to produce asymmetries, heavy tails, both linear and non-linear dependence and, to calibrate them, there is no need for liquid multivariate derivative quotes.     

Can sustainable investments outperform traditional benchmarks? Evidence from global stock markets

To contribute to overcoming global sustainability challenges, investors have been increasingly interested in making sustainable investments and incorporating environmental, social and governance (ESG) criteria into their portfolio selection decisions and managerial activities. However, these investors and other agents interested in sustainable investment need updated and robust information to support their decision making. We analyzed the performance of several Dow Jones Sustainability Indices (DJSIs) and compared them with their respective market benchmarks from 2013 to 2018. The indices comprise the following regions and countries: the world, the Asia‐Pacific, Europe, emerging markets and the US. The analysis was conducted based on both classic and modern portfolio metrics. The results suggest that sustainable investment performance is still heterogeneous worldwide, but there is a promising opportunity for investors to obtain superior risk‐adjusted returns in certain regions while incorporating sustainable investment practices. The findings are of utmost importance to financial market practitioners, business managers, academics and other stakeholders interested in promoting investments, corporate practices and scientific knowledge to achieve the Sustainable Development Goals (SDGs).     

Microfinance,subsidies and local externalities

We analyse equilibrium borrowers’ effort and the cost of microcredit loans in the presence of moral hazard, project correlation and subsidies under group lending conditions. Our results show that under the assumption of endogenous effort, project correlation has significant effects on borrowers’ effort only when it is determined by asymmetric (positive or negative) shocks. These findings indicate that the well-known negative effect of within-group (symmetric) project correlation on group lending with joint liability disappears once endogenous effort is taken into account. We also analyse the effects of subsidised lending (and asymmetric correlation) on the relative convenience (in terms of borrowers’ effort) of the alternative (1) between group lending and individual lending with notional collateral and (2) among three different market structures of the microfinance industry.     

Toward a Model of Understanding Strategic Decision‐Making in Micro‐Firms: Exploring the Australian Information Technology Sector

This study explores strategic decision‐making (SDM) in micro‐firms, an economically significant business subsector. As extant large‐ and small‐firm literature currently proffers an incomplete characterization of SDM in very small enterprises, a multiple‐case methodology was used to investigate how these firms make strategic decisions. Eleven Australian Information Technology service micro‐firms participated in the study. Using an information‐processing lens, the study uncovered patterns of SDM in micro‐firms and derived a theoretical micro‐firm SDM model. This research also identifies several implications for micro‐firm management and directions for future research, contributing to the understanding of micro‐firm SDM in both theory and practice.     

Why Do We Buy Traditional Foods?

Consumer behavior toward traditional specialties varies according to the cultural context of consumption. It thus becomes crucial to develop marketing strategies that target segments with different levels of familiarity with food. Our article purposes to analyze the purchase drivers of traditional foods known to consumers because of their reiterated consumption. The importance of the product’s attributes, the purchasing motivations, and the information channels are studied by applying the CUB model, which utilizes a probabilistic structure that simulates the individual’s psychological mechanism in adopting a choice of preference. The case study is that of extra-virgin olive oil in Italy, where this product is a fundamental element of the culinary tradition. The results show that in the ambit of traditional specialties, in contexts of elevated familiarity, the traditional information channels of marketing are less effective and call for strategies based on a more direct connection between consumer and producer.
