Remittances in Mexico and their unobserved components

ABSTRACT

The present study aims to determine the common trends and the permanent and transitory components of remittances received by Mexican households. This is done by estimating a small Dynamic Factor Model (DFM), using the approach first proposed by Gonzalo and Granger [1995. “Estimation of Common Long-memory Components in Cointegrated Systems.” Journal of Business and Economic Statistics 13 (1): 27–35], determining the number of common trends subject to the cointegration results. The study also shows the similarities between this small DFM with respect to large DFM, which are widely used in the econometric literature. The results indicate the presence of one cointegration relationship. Consequently, there are four common trends. The cointegration relationship is negatively dominated by Mexico's economic activity and positively by the US industrial production. The effects of the exchange rate and the US unemployment rate are positive, but less relevant. This economic scenario leads to remittances exceeding its permanent component.     

The Problem of Constructive Misalignment in International Business Education: A Three-Stage Integrated Approach to Enhancing Teaching and Learning

Past evidence suggests that constructive misalignment is particularly problematic in International Business (IB) education, though this paradigm has received limited research attention. Building on the literature of three independent teaching methods (threshold concept, problem-based learning, and technology-based learning), this study contributes to the IB education literature by integrating the three existing methods in a co-complementary and co-supporting manner, and carefully implementing them across three subsequent stages spanning across the length of the IB course. Empirical evidence on student satisfaction and assessment performance shows its usefulness in reducing the negative effects of constructive misalignment among the sampled students. The approach provides practitioners with refreshed insights into how the three independent methods can be integrated to create greater value for learners.     

Exchange rate volatility and United Kingdom trade: evidence from Canada,Japan and New Zealand

This paper investigates the influence of exchange rate volatility on the real imports of the United Kingdom from Canada, Japan and New Zealand during the period 1980–2003. The Johansen multivariate cointegration method and the constrained error correction (general-to-specific) method are applied to study the relationship between real imports and its determinants (including exchange rate volatility). Conditional variance from the GARCH(1,1) model is applied as exchange rate volatility. Both nominal and real exchange rates are employed in the empirical study. Results indicate a significant effect of the exchange rate volatility on real imports. These exchange rate volatility effects are mostly positive. The author thanks an anonymous referee, the editor and Myles Wallace for several useful comments and suggestions. Any remaining errors and omissions are the author’s responsibility alone.     

Exchange Rate Regime and Demand for Reserves: Evidence from Kenya,Mexico and Philippines

This paper empirically investigates the demand for international reserves (and foreign exchange reserves) during fixed and floating exchange rates periods in three developing countries: Kenya, Mexico and Philippines. Based on theoretical models, three factors are identified as important for the demand of international reserves and foreign reserves: average propensity to import, volume of imports and variability of reserves. The paper employs the cointegration methodology and error correction method to investigate the relationships. Cointegration tests results indicate a reliable long-run stationary relationship between the international reserves (and foreign exchange reserves) and the stated explanatory variables across countries and sub-periods of fixed and clean float. The error correction results indicate causality from the explanatory variables to the reserves during both the short and long run. This is true during both the fixed and the floating periods.

中国金融资产收益率与宏观经济相关性研究

基于Lamont设立的经济跟踪指标组合体系,选择1997年5月至2006年11月的数据构建了股市各项资产收益率与宏观经济指标之间的多元OLS回归模型(ETP)、向量自回归模型(VAR)、协整检验和向量误差修正模型(VEC),全面考察了我国股市资产收益率与宏观经济变量之间的互动关系。研究发现,OLS模型与VAR模型中资产收益率的回归系数大多不显著,虽然宏观变量和金融资产收益率存在长期均衡关系,但是这种均衡关系非常松散和不明朗。     

The short and long-run interdependencies between the Eurozone and the USA

We estimate quarterly cointegrating vector autoregressive models for the Eurozone and the USA based on long-run restrictions derived from a dynamic open economy model. Three long-run relations between the Eurozone and the USA emerge: relative purchasing power parity, international interest parity and a stationary output gap between the two economies. Generalized impulse response functions show differences in the dynamic adjustment of the two economies. Due to the I(1)-characteristic of both output series and the stability conditions imposed by the long-run equilibrium relationships, shocks to the model produce level effects only, while growth rates converge to their long-run averages.

Electrification and energy productivity

Energy productivity is crucial for sustainable development. We use cointegration analyses to investigate the effect of electricity on energy productivity in Swedish industry from 1930 to 1990. Electricity augmented energy productivity in those industrial branches that used electricity for multiple purposes. This productivity effect goes beyond “book-keeping effects,” i. e. it is not only the result of electricity being produced in one sector (taking the energy transformation losses) and consumed in another (receiving the benefits).     

Identification and dimension of the NAIRU

In this paper, we have re-examined the identification of the NAIRU and presented a well-defined reduced form for analysing the equilibrium unemployment rate, using a cointegrated VAR model. We have stated that the NAIRU estimates using the conventional reduced form (or Phillips curve) models are misleading since the natural rate of unemployment cannot be considered as a fixed point calling for the ceteris paribus assumption for all the data involved. This implies that the NAIRU estimates are unable to provide valuable information on the labour market status.     

The cause of Danish unemployment: Demand or supply shocks?

We study the Danish unemployment experience 1905–92 using a common trends model with cointegration constraints. To justify the identifying assumptions about the cointegration vectors and the common trends we present a simple macroeconomic model of the labor market. The model determines the long run behavior of labor productivity, employment, unemployment, real product and real consumer wages. The empirical results give support for three cointegration relations and two common trends. Based on the economic model the trends are interpreted as representing labor productivity (technology) and labor supply. With unemployment being nonstationary, the common trends analysis indicates that labor supply shocks is the primary source for explaining the behavior of unemployment.

地区规模、集聚外部性与区域创新能力

采用2005-2013年中国内地30个地区（除西藏外）27个工业行业数据,构建面板门槛模型,实证检验不同地区规模下,区域内多样化集聚（Jacobs外部性）、专业化集聚（MAR外部性）和企业竞争对区域创新能力的影响。结果显示,当地区规模较小时,多样化集聚、专业化集聚与企业竞争都对区域创新能力具有显著促进作用,但随着地区规模的日益增大,多样化集聚对区域创新能力的促进作用明显减小;专业化集聚、企业竞争与区域创新能力之间存在倒U型关系。
