Opis:
The aim of the paper was examining Granger causality between rates of return of precious metals. The study covers the period from 2008 through 2013 and includes gold, silver, platinum, and palladium. After developing statistical analysis and confirming stationarity of time series under consideration, the Granger causality test was run. Its results revealed a bilateral causation between silver and platinum rates of return. The study also detected causal relationships flowing from gold and palladium rates of return to silver returns.

Opis:
The paper examines relationships between selected stock market indices in Western Europe, Central Europe, and the United States. The study focuses on two periods, from January 1998 to August 2006 and from September 2006 to December 2016. The first one includes stock quotes from before the financial crisis while the second one covers the crisis and changes in the economic situation in post-crisis years. Relationships between stock market indices in developed economies were more frequent and durable than in Central Europe, although they were subject to changes. In our investigation into Granger causality relationships we observed changes in these relationships and in their direction for stock markets in Central Europe, while bidirectional relationships between indices in developed economies remained stable over time. Changes in relationships between indices, in particular long- -term interdependences, may result from the impact of the 2008 financial crisis. The increased number of causality relationships for the markets in Central Europe may testify to the advancing integration of the EU common market.

Opis:
The recent increase in commodity price levels has resulted in the launch of a number of new commodity funds also in Poland. Since these funds do not have long quotation records, the study designed to answer the question whether changes in prices of commodities on world markets Granger-cause changes in quotations of participation units in specialized commodity funds in Poland, must have been limited to a 3-year-period. It includes 8 commodity funds, 11 commodities and 2 stock indices. Their log-returns constitute the base for calculating some descriptive statistics, testing for normality and stationarity. In order to achieve the goal of the research the Granger causality test is adopted. Its results exhibit Granger causality between commodity returns and majority of commodity fund returns, whereas in only few cases there is Granger causality running from stock indices returns to commodity funds returns.

The country is characterized by political stability, economic attractiveness of tax-free zones for investors, and also has a good infrastructure, communication network, as well as one of the best education systems in their continent. The aim of the study is to verify whether the selected factors affect the volume of consumption (per unit) in Uruguay. Selected factors are investment (per capita), imports (per capita), exports (per capita), government spending (per capita) and the level of consumer prices. Individual data are annual data, and analysis period in the years 1950-2009. Audit of Granger causality indicates that the inclusion of the individual regression equations delayed variables can better explain and predict the evolution of the size of consumption in Uruguay.

Opis:
Butter and skimmed milk powder (SMP) are considered to be primary dairy commodities as they enable storage of fat and protein. The spread between butter and SMP prices in the European Union (EU) has been stable for many years. However, in 2016, butter prices suddenly increased to reach extremely high levels while SMP prices remained low. As a consequence, the price spread between milk fat and protein has surged, leading to severe imbalance in the EU dairy market. Some professionals argue that the main reason for this occurrence are large intervention stocks of SMP accumulated by the European Commission (EC) which weigh on prices. Nevertheless, no one has yet proved the existence of a causal relationship between the intervention stocks accumulated by the EC and the butter/SMP price spread. Hence, the purpose of this paper is to test that hypothesis. The causality between the EC intervention stocks and the butter/SMP price spread was tested using the Granger causality approach. The results show that the difference between butter and SMP intervention stocks accumulated by the EC Granger-causes the butter/SMP price spread while there is no causality in the opposite direction, which supports the hypothesis tested.

Opis:
The paper explores the long-term causal relationships of Malaysian palm oil exports with the real effective exchange rate of the respective importing countries, palm oil consumption, vegetable oil production, and GDP growth. The study applied panel cointegration and causality approaches based on data from 10 main palm oil importing countries between 2004 and 2018. The impacts of economic growth, the effective real exchange rate, and the production of other vegetable oils by the main palm oil importing countries on Malaysian palm oil exports were found to be negative. However, palm oil consumption by the main palm oil importers was found to be a statistically significant positive determinant of Malaysian palm oil exports. This finding indicates that consumption has a direct positive effect on the demand for exports. A panel Granger causality analysis revealed a unidirectional causality between importing countries’ production of other vegetable oils and Malaysian exports of palm oil.

Opis:
This study aims to investigate the relationship between financial development and economic growth in different time horizons for Turkey. In this study an ensemble of wavelet analysis and Granger causality test were used. PSC was used to represent financial development and GDP was used to represent growth. The annual data used are for the period 1961–2018. The result obtained for a one year period shows that the demand-following hypothesis is valid for Turkey. Financial development is the Granger cause of growth and positively affects growth. The financial sector should be supported for growth in the short term. While there is no causal relationship for the 2–4 year period, bidirectional causality relationships were determined for the periods of 4–8 years, 8–16 years and 16–32 years. Because variables are a Granger cause of each other and affect each other in a positive direction supporting the financial sector is a preferable policy when the purpose is to achieve growth in the long run.

Opis:
Aim/purpose – The aim of this study is to empirically investigate the influence of money supply on inflation in Nigeria. The study was borne out of the curiosity to reexamine the immediate cause of the alarming rate of inflation in Nigeria which is adversely affecting the general welfare of Nigerian populace. Design/methodology/approach – The study employed co-integration test and error correction approach on annual time series data spanning from 1970 to 2016 to ascertain both the long run and short run dynamics relationship among the variables under consideration. Findings – The results showed that money supply does not considerably influence inflation both in the long and short run possibly because the country is in recession. The error correction model has the correct sign of negative and it is significant meaning that about 21% of the errors are corrected yearly. The Granger causality outcome demonstrates that, there is no causality between money supply and inflation in Nigeria within the study period and vice-versa. Research implications/limitations – The implication of this is often that there are different economic conditions which are key determinant of inflation in Nigeria. The study recommends that the government should diversify the economy, minimise importation by encouraging local production of products and services. The Central Bank of Nigeria should guarantee an exchange rate policy that is essentially determined by the state of the economy and not by speculators being a net importation economy. Also, the Central Bank of Nigeria should look inwards into the current interest rate and see how it can be regulated in such a way that will encourage private and foreign investors to be able to invest in the country. This in turn, successively increases income, infrastructure development and economic growth at large. Originality/value/contribution – This paper has been able to confirm that money supply is not a key factor that trigger up inflation in Nigeria.

Opis:
The paper’s primary goal is the evaluation of the relationship between minimum wage, employment, and unemployment in Poland in the past two decades. It presents an overview of theoretical aspects of minimum wages, the main motivations behind its implementation, as well as potential negative consequences. The minimum wage in Poland is presented in comparison to other European Union countries. Finally, using a Toda-Yamamoto approach and quarterly data covering the years 2002–2019, the Granger causality between the Kaitz index and selected labour market indicators is examined. The results indicate the presence of unidirectional Granger causality between the Kaitz index and the general unemployment rate. It does not indicate similar relationships for other examined indicators, including employment rate and youth unemployment rate.
Celem artykułu jest ocena zależności między wynagrodzeniem minimalnym, zatrudnieniem i bezrobociem w Polsce. Przedstawiono przegląd teoretycznych aspektów płacy minimalnej, głównych motywacji za jej stosowaniem, a także potencjalnych negatywnych konsekwencji. Płaca minimalna w Polsce zostaje przedstawiona na tle innych krajów Unii Europejskiej. Wykorzystując metodę Toda-Yamamoto oraz dane kwartalne GUS i ILOSTAT obejmujące lata 2002–2019, zbadano przyczynowość Grangera między indeksem Kaitza a wybranymi wskaźnikami rynku pracy. Wyniki wskazują na istnienie jednokierunkowej przyczynowości Grangera między wskaźnikiem Kaitza a ogólną stopą bezrobocia. Nie wykryto podobnych zależności w przypadku pozostałych badanych wskaźników, w tym między innymi stopy zatrudnienia i stopy bezrobocia wśród osób młodych.

Opis:
Research concerns causality between FDI inflows and real GDP growth in ten countries: France, Germany, Japan, U.S., U.K., Brazil, China, India, Russia and South Africa during the period 1971-2012. The analysis is based on Granger-causality tests. The study is aimed at answering a question whether there is one way or two-way causality (or no causality at all) between FDI inflows and real GDP growth in G-5 and BRICS countries. According to the Granger-causality tests one-way causality occurs only in the case of Japan and India. Thus, Granger-causality between FDI inflows and real GDP growth seems to be a country-specific issue and any genral conlusions concerning developed or developing economies are not justified.

Opis:
This paper deals with an analysis of the information flow on and between three European stock markets operating in Frankfurt, Vienna, and Warsaw. We examine causal links between returns, volatility, and trading volume as well as the time of reaction to a news release and changes in the duration of causal interference. To model the conditional variance, we use the ARMA(1,1)- EGARCH-M(1,1) model. We investigate linear and nonlinear Granger causalities on the three stock exchanges using Bayesian large sample correction of the critical values in significance tests. The results of our study confirm the dominant role of the Frankfurt Stock Exchange, since the most significant linear relationship is the causality running from DAX30 returns to the returns of the ATX20 and WIG20 (which exists irrespective of the time of the day, presence of important public news, and lag length of the underlying VAR models). Moreover, the empirical results of this paper confirm the strong impact of announcements of macroeconomic news from the U.S. economy on the structure of both linear and nonlinear causal links on the three markets under study

Opis:
The minimum wage is the wage policy instrument that affects, among others, labor costs and elimination of negative forms of competition. In political-economic and scientific circles there is an ongoing discussion on the legitimacy of raising the minimum wage and its impact on employment. The main aim of this study is to determine the impact of changes in the minimum wage on labor demand of young people in Poland. It has been realized through three specific aims. On the basis of causality test it has been shown that both the level of the minimum wage and its relation to average earnings are the Granger causes of the number of working people aged 15-29 in Poland in the period 1990-2013. The results of the econometric model estimation showed, ceteris paribus, the negative impact of both these variables on the demand for labor of young people, with the minimum wage effect being lagged by one year. The variant forecasts until 2020, with different assumptions about the minimum wage, indicate the largest number of working if the minimum wage does not exceed 40% of the average earnings, while maintaining the current growth rate of the minimum wage. A noticeable decrease in employment is yet expected in the case of a large increase in this wage, regardless of its relation to the average earnings.

Opis:
Price transmission studies have become increasingly important in Sub-Saharan Africa over the past decades because of its nature of providing clear and insightful information into these markets. In this study, the price transmission mechanism is described with an agricultural product within the dairy industry, namely pasteurized liquid milk. The aim of this study was to investigate and analyze the nature of the price transmission mechanism for pasteurized liquid milk in South Africa. The study used secondary time series data that covered a sample size of 17 years (2000–2016) for pasteurized liquid milk. The Granger causality test and the Vector Error Correction Model were used for data analysis. The Granger causality tests suggest that a bidirectional causal relationship exists between processor and farmgate prices, and also between retail and processor prices. On the other hand, retail prices were found to have a unidirectional causality effect on farmgate prices. The VECM results showed asymmetric price transmission, implying that retailers and processors react quicker to a price increase than to a price decrease. A price monitoring policy is suggested to be put in place in order to protect the consumers from unfair prices passed on by the retailers.

Tests for two periods from January 2015 till December 2019 and from June 2016 till May 2021 have been performed. This allowed the period of relative stability from the time of economic shock caused by the COVID-19 pandemics followed by various restrictions imposed by the governments to be distinguished. A bivariate VAR model to selected search terms and the value of the WIG20 index was applied. Aeftr using AIC to establish the optimal number of lags the Granger cau sality test was performed. The increased empirical relationship has been conrfimed be tween twelve EPU related terms and changes in the WIG20 index in the second period versus six terms for the pre-COVID period. It was also found that in the post-COVID period the intensity of reverse relations increased.

We repeat similar comparison for data set extended until the end of April 2010, use ARMA/ARMAX and GARCH models with stock indices as additional regressors, for volatility and returns of EURPLN, EURUSD, USDPLN exchange rates. Marked increase in volatility during crisis, negatively affected quality of models. After crisis volatility and returns seem to stabilize, hence exchange rate risk seems to decline gradually. There is a slight improvement in quality of models after the crisis."
