In this article, we develop a general method for testing threshold effects in regression models, using sup-likelihood-ratio (LR)-type statistics. Although the sup-LR-type test statistic has been considered in the literature, our method for establishing the asymptotic null distribution is new and...

In this paper, we analyze which currencies can be regarded as safe haven currencies. Our empirical approach allows us to distinguish between a low- and high stress regime, and to control for the impact of carry trade reversals and other fundamental determinants. We therefore address the question...

Price stability is the ultimate objective of the State Bank of Vietnam (SBV). In addition, in a small export-led economy, such as Vietnam, the study of exchange rate volatility is crucial for the country's economy due to its impact on inflation via exchange rate pass-through (ERPT). This study...

The cost of living has shown a gradual upward trend in recent years, which has seriously impacted the quality of life and well-being of residents. This study empirically examines the impact of the digital economy on residents' cost of living and the mechanisms behind it by measuring the digital...

In this paper, we study the estimation and inference of the threshold model with hybrid local stochastic unit root regressors. Our main contribution is to propose an estimator that generalizes the threshold model with various forms of nonstationary regressors and to obtain its limiting...

The effect of FinTech on income inequality in China and the characteristics of the existing thresholds are examined in this study based on China provincial panel data from 2011 to 2020 by combining dynamic panel differential GMM with panel threshold models. As revealed by this study, (1) FinTech...

Functional agricultural marketing system is purported to be the silver bullet and multiplier for stimulating production and consumption and, accelerating the pace of economic and rural enterprise development. Thus, understanding effectiveness of agricultural products market price transmission...

Threshold Autoregressive Models (TAR) along with other nonlinear time series models have attracted much attention in recent years in time series analysis. TAR models have been applied to a variety of time series. It has been reported that they have a good in sample fit but like many other...

This paper re-examines the issue of the existence and the level of inflation threshold in the relationship between inflation and growth in Nigeria, using three different approaches that provide appropriate procedures for estimating the threshold level and inference. While Sarel's (1996) approach...

This paper studies nonlinear behavior of high-frequency financial data and employs nonlinear hierarchical models for analyzing such data. We illustrate the analysis by modeling the transaction-bytransaction data of IBM stock on the New York Stock Exchange for a period of 3 months. The variables...
