Productivity Growth Determinants of Differently Developed Countries: Comparative Capital Input Results
Toma Lankauskiene
PDF
Abstract
The article aims to apply the growth accounting methodology to the Baltic countries in order to obtain detailed productivity growth determinants in the aggregated market economy with a particular focus to capital input. To this end, a new database following the KLEMS methodology for tangible and intangible capital indicators is constructed. The paper analyses determinants’ genesis and growth tendencies in the context of more developed countries and uncovers the productivity gains associated with different types of capital assets. First, an overview of the economies during the period researched is presented. Second, a methodology is developed to derive new intangibles and EU KLEMS data for the Baltic countries. Third, statistical data are constructed for all economies and the growth accounting method is applied in order to obtain comparable results. Finally, economic analysis is conducted to detect certain aspects of the growth determinants for differently developed and structured economies.

Are Slovak Retail Gasoline and Diesel Price Reactions on Crude Oil Changes Asymmetric?
Karol Szomolányi, Martin Lukáčik, Adriana Lukáčiková
PDF
Abstract

The paper explains why the Slovak retail gasoline and diesel prices rise more rapidly when the price of crude oil increases and fall slowly when the price of crude oil decreases. The weekly data of Slovak retail gasoline and diesel prices and European Brent oil prices since the first week of 2009 till the second week of 2019 are used. The error correction model with irreversible behaviour of explanatory variables is specified to test asymmetric response of retail gasoline and diesel prices on changes in crude oil prices. By our assumption of linked gasoline and diesel markets, we also adopt a common co-integration relationship. Consequently, the vector error correction model is included in the analysis. An expected asymmetry in the retail fuel price reactions on crude oil changes is rejected. Our results may be informative for the future research in Slovak business cycles and in market structure of retail gasoline and diesel sellers.

Keywords

Gasoline and diesel retail prices, crude oil prices, irreversible model, co-integration, asymmetries between the price of crude oil and the retail fuel

 

 
CO2 Emissions-Economic Growth Relationship Revisited: New Insights from the Time-Varying Cointegration Approach
Jeyhun I. Mikayilov, Nicholas Apergis, Fakhri J. Hasanov
PDF
Abstract
One of the most discussed topics of Environmental economics is the choice of the appropriate functional form to examine the income-environmental impact relationship. Since the developing economies encounter different development stages, the use of relevant specification and technique gains special importance to reveal the country specific relationship. Considering the afore-mentioned points, this study employs the time-varying cointegration approach to investigate the CO2 emissions-economic growth relationship in the case of developing country, Azerbaijan. Time-varying cointegration approach a) takes into account the varying nature of elasticity of emissions and b) does not require the functional specification to be a polynomial. The results document a long-run relationship between carbon emissions and income. The study also concludes that the EKC hypothesis does not hold in Azerbaijan. The positive and time-varying income elasticity of carbon emissions, slightly decreasing at the end of the time period, can be seen as an indication that the country has implemented a number of successful emission/pollution regulatory measures.

Analysis of Price Changes in Socially Important Food Products: Example of Azerbaijan
Vilayat Valiyev, Malik Mekhdiyev, Arzu Suleymanov, Shaig Ganbarli
PDF
Abstract
The aim of the research is to keep the price formation process of socially important food products under control and facilitate timely disclosure of tendencies that are contrary to market relations.
In this paper, some 19 socially important food products have been selected and tried to identify the share/ contribution of the factors affecting their price changes in the example of Azerbaijan economy.
Econometric estimation methods are used in the paper. Database of the analysis is based on the official figures of the State Statistical Committee (SSC) of the Republic of Azerbaijan, covering the period from January 2016 to December 2017.
As a result, the methods for determining the contribution of factors in price fluctuations of socially important food products are presented, and the empirical results are interpreted as an example of the Azerbaijani economy.

Spatial Variations in the Educational Performance in Slovak Districts
Michaela Chocholatá
PDF
Abstract
This paper deals with the spatial analysis of the educational performance measured by the average percentage Maths scores achieved in individual districts of Slovakia in Testing 9 during the school year 2018/2019. Besides identification of the spatial patterns in test scores achievements, the paper tries to investigate the impact of selected socio-economic variables (average nominal monthly wage and unemployment rate) onto the test scores achievements. Since we suppose the significant impact of the socially disadvantaged background onto the test results, corresponding dummy variable was taken into consideration as well. The ordinary least squares (OLS) estimation of the global linear regression model was followed by the local spatial approach using the geographically weighted regression (GWR) to capture the geographical variability of estimated parameters. Spatial variations in the relationship among the educational performance and the selected socio-economic variables were confirmed.

Using a Mediation Test to Determine the Causes and Effects of Vietnamese City-Based Consumer Patriotism
Ha Van Son, Ngoc Chu Nguyen Mong, Trong Hoang
PDF
Abstract
This study developed the measurement model of consumer patriotism, proposed by Ngoc and Trong (2018), in the context of Vietnamese city-based consumers. In addition to testing the stability of the measurement model for consumer patriotism, the study focused on investigating the role of cause and effect in consumer patriotism, using the mediation test process of Frazier et al. (2004). The study was conducted in a consumer product context. A random sample of 300 households in Hanoi, the capital of Vietnam, was chosen for collecting data. The results show that patriotism is the cause of consumer patriotism, and consumer patriotism has positive effects on consumer ethnocentrism and consumer domestic product buying behavior. The study results can help improve the effectiveness of campaigns to promote consumption of domestic product.

Does Changes in Characteristics of a Fixed Exchange Rate Regime Impact Conditional Volatility? Evidence from the Case of Morocco
Hamza Bouhali, Mohammed Salah Chiadmi, Fouzia Ghaiti
PDF
Abstract

This article aims to exhibit and study the impacts that changing characteristics of a fixed exchange rate regime has on conditional volatility. To do so, using the U.S. dollar dirham (USDMAD) daily closing rates over 23 years, we compare the GARCH model results of four segmented sub-periods to each other and then to the global period of the study to detect disparities. The main result is that changes in exchange rate regime characteristics do impact the conditional volatility. Therefore, we recommend that the study of conditional volatility should use periods with no changes in the characteristics of the exchange rate regime to avoid bias. Otherwise, the use of segmented sub-periods should be adopted to take account of these changes. Finally, we present some key results about the impacts of these changes in Morocco’s exchange rate regime on the conditional volatility.

A Territorial Model for Centralised Data Collection Implementation
Loredana de Gaetano, Angela Digrandi, Pasquale Papa
PDF
Abstract

The Italian National Statistical Institute (ISTAT) carries out the survey on the maritime transport of goods and passengers, as required by the Regulation (EU) No. 1090/2010 of the European Parliament and of the Council. The survey is a census as it refers to the final overall amount of the arrivals and departures recorded in Italian ports.
In order to improve the quality of data collection, within the new ISTAT organizational structure, introduced during 2016, the Central Directorate for data collection was created, specifically dedicated to the design, organization, implementation and integration of the data collection activities.
Then a specific project assigned to a selected number of ISTAT territorial offices the new role of conducting data collection activities on the territory.
The analysis is aimed at presenting the improvements both in terms of process efficiency and quality of the results expected from the new data collection approach.

Keywords
Data collection, maritime transport, process efficiency
