The Taylor Rule and the Practice of Central Banking
2010
The Taylor rule has revolutionized the way many policymakers at central banks think about monetary policy. It has framed policy actions as a systematic response to incoming information about economic conditions, as opposed to a period-by-period optimization problem. It has emphasized the importance of adjusting policy rates more than one-for-one in response to an increase in inflation. And, various versions of the Taylor rule have been incorporated into macroeconomic models that are used at central banks to understand and forecast the economy. ; This paper examines how the Taylor rule is used as an input in monetary policy deliberations and decision-making at central banks. The paper charac…
Macroeconomic Modelling in EMU: How Relevant is the Change in Regime?
2007
We analyse the likely effects of changes in the monetary and financial regimes of EMU countries on the dynamics of output and inflation. In particular, we evaluate the impact of the regime shift on the forecasting performance of reduced-form models. Data for both the pre-EMU and the EMU regimes are generated by a relatively standard open-economy-DSGE model with sticky prices and wages and restricted access to financial markets for some individuals. We find that the effects of the shift in the monetary regime on the processes followed by macroeconomic variables depend on the nature of the shocks hitting the economy. For plausible shocks distributions the reduction in the accuracy of VAR-base…
Open Educational Resources’ impact and outcomes: The essence of OpenKnowledge and its social contribution
2018
This article identifies the main social contributions of Open Educational Resources (OERs), their impact and the results of several initiatives related to them. Based on a theoretical and reflexive framework, we analyze the evolution of business models around OERs, their contribution to open knowledge and the common educational policies related to this phenomenon. Finally, we point out the new horizons and models of knowledge based on OERs. Design/methodology/approach: This study utilizes a theoretical and conceptual framework based on references coming from journals with an impact factor, complemented with quotes by important authors and OER representatives. The review offers a conceptual …
A simple model of income, aggregate demand and the process of credit creation by private banks
2013
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 capabl…
The Role of Risk and Information for International Capital Flows: New Evidence from the SDDS
2012
In this paper, we investigate whether better information about the macroeconomic environment of an economy has a positive impact on its capital inflows, namely portfolio and foreign direct investment (FDI). The purpose of our study is to explicitly quantify information asymmetries by compliance with the IMF's Special Data Dissemination Standard (SDDS). For FDI, we fi nd statistically signi cant and robust support for this hypothesis: SDDS subscription increased inflows by an economically relevant magnitude of about 60 percent. We also find evidence of aversion against political and macroeconomic risk as determinants of portfolio and FDI flows and use a non-parametric test for spatial correl…
General Economic Order Quantity Model for Lot Sizing with Quality Loss and Process Analysis
1995
In this paper a new model GEOQ is proposed to decide the optimal lot sizing in production. The GEOQ modifies the classical EOQ method in several aspects. First it considers that there is always a probability that the production goes out-of-control; then it takes the time the process goes out-of-control as a stochastic quantity; and finally it adds quality loss to the economic models. The quality loss is calculated according to Taguchi’s quadratic loss function. and depends on the process failure models. Therefore, the optimal lot sizing is decided not only by the set-up cost and the holding cost but also by the quality loss during the manufacturing process.
Culture at work: how culture affects workplace behaviors
2014
Purpose – The purpose of this paper is to give structure to the argument that “culture matters.” Further, the aim is to show how cultural differences shape the use of incentives within firms and point toward culturally affected degrees of efficiency. Design/methodology/approach – The paper incorporates differences in the evaluation of the stimuli money, order, and monitoring into a simple efficiency wage model. Profit maximizing firms are assumed. Findings – It is found that the use of incentives should respect the cultural surrounding. Data from a real-world analysis can partly be explained with this model, which was not done before. Research limitations/implications – The major limitation…
Assessing nonlinear structures in real exchange rates using recurrence plot strategies
2002
Purchasing power parity (PPP) is an important theory at the basis of a large number of economic models. However, the implication derived from the theory that real exchange rates must follow stationary processes is not conclusively supported by empirical studies. In a recent paper, Serletis and Gogas [Appl. Finance Econ. 10 (2000) 615] show evidence of deterministic chaos in several OECD exchange rates. As a consequence, PPP rejections could be spurious. In this work, we follow a two-stage testing procedure to test for nonlinearities and chaos in real exchange rates, using a new set of techniques designed by Webber and Zbilut [J. Appl. Physiol. 76 (1994) 965], called recurrence quantificatio…
Mozambique’s Megaproject-Based Economic Model: Still Struggling with Uneven Development?
2019
Megaprojects in aluminium production, coal and natural gas extraction, and hydropower generation play a key role in the Mozambican economy. Based on the concepts of global value chains and linkages, this chapter shows that remarkable transformations are taking place in these sectors, including the expansion of production, the attraction of FDI and the emergence of new players from the Global South who now compete with transnational companies from traditional economic partner countries of Mozambique. The authors highlight potentials (in terms of economic transformation, especially positive side effects through the provision of electricity and rehabilitation of transport infrastructure) as we…
