In this paper we propose a new framework for modelling heteroskedastic structural vector autoregressions. The identification of the structural parameters is obtained by exploiting the heteroskedasticity in the data naturally arising during crisis periods. More precisely, we provide identification conditions when heteroskedasticity and traditional restrictions on the parameters are jointly considered. Although the framework is general enough to find potential applications in many empirical economic fields, it proves to be well suited for distinguishing between interdependence and contagion in the literature related to the transmission of financial crises. This methodology is used to investigate the relationships between sovereign bond yields for some highly indebted EU countries. 相似文献
In the summer of 2014 Russia imposed a ban on most agri‐food products from countries enforcing Ukraine‐related sanctions against Russia. We use a specific factors computable general equilibrium (CGE) model to simulate the short‐run impact of this retaliatory policy. The baseline is carefully designed to isolate the impacts of the ban on the European Union (EU), Russia itself and a selection of key trade partners. The modelling of the ban follows a novel approach, where it is treated as a loss of established trade preferences via reductions in consumer utility in the Armington import function. Not surprisingly, the results indicate that Russia bears the highest income loss (about €3.4 billion) while the EU recovers part of its lost trade through expansion of exports to other markets. An ex‐post comparison between simulation results and observed trade data reveals the model predictions to be broadly accurate, thereby validating the robustness of the modelling approach. 相似文献
At a time of a global crisis with unprecedented depth and breath, this paper explores the role of accounting in real-time crisis management at local level by investigating how national stakeholders assessed the consequences of the Covid-19 pandemic in Italy, one of the most affected countries. The paper aims at augmenting knowledge on the intersection between weathering crisis and accounting. Calculative practices play an important role to help manage crises since they may foster or undermine relief and recovery efforts. Results show how decision makers used cash accounting disregarding more complete information with a wider and longer-term perspective, against some stakeholders’ and scholars’ advice. 相似文献
Recent decades have seen a substantial increase in the size and influence of the financial industry in advanced economies. Mainstream theory states that the financial sector can increase the efficiency and stability of the real economy by reducing informational asymmetries and transaction costs. Nevertheless, the rise of the financial industry has been accompanied by lower aggregate growth, increased inequality and declining financial stability. With this in mind, the main aim of the present article is to provide a different perspective on the rise of finance in developed countries, by focusing on the impact of financial markets on aggregate growth and economic (in)stability. Specifically, we analyse the role of the bargaining power of financial intermediaries in promoting (or reducing) the entrance of new enterprises in the market and find that the financial sector is essential for the good functioning of the real economy, but that an overdeveloped financial industry can reduce the incentive for new firms to start production, resulting in a negative impact on aggregate growth and economic stability.
The growing awareness about environmental issues places greater responsibility on firms to transmit information about the environmental quality of their products. One of the most innovative ways to achieve this objective is through the ‘environmental product declaration’. Unfortunately, from an operating viewpoint, there is a very little evidence on the effects associated with the introduction of this label. In lieu of this context, the paper suggests operating guidelines and a methodological approach for managers who aim to understand under which conditions the EPD can represent a useful tool for the company's competitiveness. In particular, the paper will identify
1 the specific peculiarities and requirements of the EPD;
2 the EPD parameters of attractiveness, related to its potential costs and benefits;
3 an operational framework in order to assess the EPD target audience.
In this paper, segmenting the market by educational levels, we investigate which native‐born women are more affected by an increase of low‐skilled immigrants working in the household service sector. We present a model of individual choice with home production and, using a harmonized dataset (the Cross‐National Equivalent File), we estimate its main comparative static results. The results suggest that the share of immigrants working in services is positively associated with an increase of native‐born women's labour supply at the intensive margin, if skilled, and at the extensive margin, if unskilled. Moreover, the results show that these effects are larger in countries with less‐supportive family policies. 相似文献
This paper presents a small macroeconomic model describing the main mechanisms of the process of creation by the private banking system. The model is composed of a core unit—where the dynamics of income, credit and aggregate demand are determined—and a set of sectoral accounts that ensure its stock-flow consistency. In order to grasp the role of credit and banks on the functioning of the economic system we make an explicit distinction between planned and realized variables, thanks to which, while maintaining the ex-post accounting consistency, we are able to introduce an ex-ante wedge between current aggregate income and planned expenditure. Private banks are the only economic agents capable of filling this gap through the creation of new credit. Through the use of numerical simulation we discuss the link between credit creation and the expansion of economic activity, also contributing to a recent academic debate on the relation between income, debt and aggregate demand. 相似文献
A central aspect of the efforts to improve public healthcare systems often is a provider’s management accounting system (MAS). The article focuses on a change effort for a hospital’s MAS. The effort involved implementing low-cost information technology designed to improve efficiency and effectiveness in operating rooms. The article aims to identify and discuss the factors that led to the hospital’s success in achieving improved outcomes at lower costs via the improvement of its MAS. The analysis uses a theoretical framework that can assist managers to identify methods that can help to foster the factors needed for effective change implementation. 相似文献
