We propose two robust bootstrap-based simultaneous inference methods for time series models featuring time-varying coefficients and conduct an extensive simulation study to assess their performance. Our exploration covers a wide range of scenarios, encompassing serially correlated,...

This study aims to explore the relationship between public debt and trade openness on economic growth in the context of the Indonesian economy. The symmetric model (Autoregressive Distributed Lag/ARDL) and the asymmetric model (Nonlinear ARDL) are employed to estimate the association among the...

This paper analyzes the integration of the American, European, and Asian natural gas markets over the period 2016-2022, with a focus on how the demand shock caused by the COVID-19 pandemic and the supply shock caused by geopolitical tensions in the European market affected this integration. We...

The main goal of this research article is to analyze the dynamic finance-growth connection using Jordan's developing market economy as a case study. For this, indicators of financial development for the relatively long-term period 1980-2020 have been compiled. This relationship is investigated...

This study explores the effect of disaggregated oil price shocks on Zambia’s historic headline inflation rates. To quantify the contemporaneous impact of oil price shocks on inflation, a Structural Vector Autoregressive Model (SVAR) is utilised, which is supplemented with Impulse Response...

The service sector in Uganda emerged prematurely as the leading driver of economic growth. This was before the country fully industrialised as described under the dual economic development model. Despite the enormous contribution of the service sector to economic growth in Uganda, an empirical...

Over the past two decades, the Black Sea region has exhibited significantly growing wheat production and exports. In 2017/18, Russia ultimately became the world’s largest wheat exporter, a position that was held by the USA for decades. Mostly serving destination markets in the Middle East and...

The current study aims to explore the role of various macroeconomic factors in determining corporate investment. Using firm-level data of six Gulf Cooperation Council (GCC) region countries for a 14 year period (2007-2020), the current study establishes the empirical analysis by employing the...

This study uses panel Granger causality and cointegration tests to examine the relationship between income per capita and control of corruption in the Eurozone. The analysis covers the entire Eurozone and subgroups of countries from 2002 to 2021. The results show that there is not a...

The size of the informal economy in Poland is estimated by means of the Currency Demand Approach (CDA). Using quarterly data for the period 1999–2019, we adopt two separate econometric approaches. First, we specify a single equation model to estimate it with the Fully-Modified OLS method....

The extant literature has produced mixed evidence on the relationship between financial development and ecological sustainability. This work addresses this conundrum by investigating financial development's direct and indirect consequences on ecological quality utilizing the environmental...

This study investigates the asymmetric relationship between global and national factors and domestic food prices in Turkey, considering the recent rapid and continuous increase in domestic food prices. In this context, six global and three national explanatory variables were included, and...

The current study extends the previous literature by exploring the effects of a newly discovered driver, i.e., import taxes (as a proxy for commercial policies), on the consumption-based carbon emissions (CCO2e) for 1990Q1-2017Q4. For empirical analysis, several tests and methods, including...

The argument over fiscal decentralization and carbon dioxide emission (CO2) reduction has received much attention. However, evidence to back this claim is limited. Economic theory predicts that fiscal decentralization affects environmental quality, but the specifics of this relationship are...

In economics, some transactions are conducted by the bid rate, and some are conducted by the ask rate. The spread between these two rates creates an essential cost and inefficiency for the economy. Taking these problems into account, the purpose of this study was to analyze the effects of...
