Dynamic impacts of energy efficiency, economic growth, and renewable energy consumption on carbon emissions: Evidence from Markov Switching model

The intent of this study was to find out the short and long-term structural effects of energy efficiency, economic growth, and the use of renewable energy resources on carbon emissions in Thailand. We determined to use the Markov Switching ADRL model for the investigation because this method enables us to deal with the incorrect spurious short-run regression issues without the need to modify the data to attain stationarity. To predict the long-run relationship and the rate of adjustment to equilibrium, we use the error correction factor. The results of the investigation showed the presence of both short-run and long-run structural changes. It is interesting that under the two regimes, the impacts of economic growth, energy efficiency, and renewable energy use on carbon emissions are asymmetric. Because both regimes' rates of adjustment are significant and less than zero and will eventually lead to the attainment of equilibrium

Survival and Duration Analysis of MSMEs in Chiang Mai, Thailand: Evidence from the Post-COVID-19 Recovery

This study attempts to reveal the consequences of coronavirus disease 2019 (COVID-19) on micro, small, and medium enterprises (MSMEs) in Chiang Mai, Thailand. A total of 786 MSMEs were surveyed during May and August 2022, corresponding to the period when the recovery of businesses and livelihoods from the ongoing COVID-19 crisis became more perceptible. The perceptions of COVID-19’s impact on MSMEs and their survivability are explored and investigated. To achieve this goal, a copula-based sample selection survival model is introduced. This idea of the model is extended from the concept of the Cox proportional hazards model and copula-based sample selection model, enabling us to construct simultaneous equations—namely, the probability-of-failure equation (selection equation) and the duration-of-survival equation (time-to-event or outcome equation). Several copula functions with different dependence patterns are considered to join the failure equation and the duration-of-survival equation. By comparing the Akaike and Bayesian information criteria values of the candidate copulas, we find that Farlie–Gumbel–Morgenstern (FGM) copula performs the best-fit joint function in our analysis. Empirically, the results from this best-fit model reveal that the survival probability of MSMEs in the next year is around 80%. However, some MSMEs may not survive more than three months after the interview. Finally, our results also reveal that the tourism MSMEs have a lower chance of survival than the commercial and manufacturing MSMEs. Notably, the business size and the support schemes from the government—such as the debt restructuring process, the tax payment deadline extension, and the reduced social security contributions—exhibited a role in lengthening the survival duration of the non-surviving MSMEs
