Abstract Using a dataset including financial market returns and volatility proxies for several countries, we analyzed the impact of Covid-19 deaths on economy. From modeling perspective, consider spatial panel data model dynamic volatilities. Proper marginal effects are calculated to exploit information short- long-term effects. A Chow test is used identify existence structural break in each se...

This paper gives a selective review on the recent developments of nonparametric and semiparametric panel data models. We focus on the conventional panel data models with one-way error component structure, partially linear panel data models, varying coe¢ cient panel data models, nonparametric panel data models with multi-factor error structure, and nonseparable nonparametric panel data models. F...

abstract t his paper explains bilateral trade patterns between south korea and thirteen opec member countries over the period 1980-2014 using a gravity model. the estimation results show that the gravity equation fits the data reasonably well. we confirmed the existence of long term relationships between the bilateral trade flows and the main components of gravity model - gdp, income (gdp per c...

background improving efficiency of health sector is of particular importance in all countries. to reach this end, it is paramount to measure the efficiency. on the other hand, there are many factors that affect the efficiency of health systems. this study aimed to measure the technical efficiency (te) of health systems in economic cooperation organization (eco) countries during 2004–10 and to d...

Using panel data spanning 15 years, this paper investigates the persistence and correlates of subjective and consumption poverty in urban Ethiopia. Despite the decline in consumption poverty in recent years, which has been linked to rapid economic growth, subjective poverty has remained largely unchanged. Dynamic probit regression results show that households with a history of past poverty cont...

In a polygamous society, all monogamous women are virtually at risk of polygamy. However, both the anthropological and economic literature are silent on the potential impact of the risk of polygamy on economic decisions of monogamous wives. We explore this issue for Senegal using individual panel data. We first estimate a Cox model for the probability of transition to polygamy. Second, we estim...

This paper considers models for panel data in which the individual effects vary over time. The temporal pattern of variation is arbitrary, but it is the same for all individuals. The model thus allows one to control for time-varying unobservables that are faced by all individuals (e.g., macroeconomic events) and to which individuals may respond differently. A generalized within estimator is con...
