Ingår i: IZA Journal of Development and Migration. - : Sciendo. - 2520-1786. ; 11:1

Tidskriftsartikel (refereegranskat)abstract
- This paper does an empirical comparison of time-invariant and time-varying technical inefficiency measures obtained from an econometric estimation of different panel data stochastic production frontier models. It estimates four panel data specifications of frontier models widely used in empirical applications using a panel dataset from the Ethiopian cereal farming sector. The empirical results show that estimates of both the magnitude and the individual farms' rankings of persistent and transient productive efficiencies differ considerably across models and based on their agro-ecological zones location. The results further show that the cereal growing farms experience much more transient inefficiency as compared to persistent inefficiency.

- This study analyzes uni-and multidimensional poverty and inequalities in rural and small towns in Ethiopia. Unlike the unidimensional measure, the multidimensional measure of poverty shows all the channels through which poverty may manifest itself; it also shows the extent of deprivation. The analysis uses 6 dimensions with 14 indicators to construct a multidimensional index of poverty and inequalities using Ethiopian Households’ Socioeconomic Survey dataset. The study also uses multiple correspondence analyses for determining relative weights in computing a multidimensional index and conducts a stochastic dominance analysis of distribution of poverty for different population segments. The paper sheds light on the degree of inequalities in consumption expenditure and multidimensional deprivations. In addition, it also compares the degree of poverty using the conventional measure of poverty and the multidimensional approach. It also examines the determinants of household poverty status using both unidimensional and multidimensional measures using the logit model. The results show that the intensity, severity, and depth of poverty varies substantially across the 2 measures. The unidimensional measure of poverty shows that 36 percent of the households were poor as compared to 46 percent multidimensionally poor households. Moreover, demographic, regional, and household heads’ characteristics also affect households’ poverty status.

Households’ willingness to pay and preferences for improved cook stoves in Ethiopia
- 2021

Tidskriftsartikel (refereegranskat)abstract
- This paper examines households’ preferences, willingness to pay, and determinants of adopting improved cook stoves in rural Ethiopia. The study uses primary household data selected randomly from three districts in Ethiopia’s Oromia region. The data was collected using a mix of contingent and choice experiment methods of valuation. The former used a double-bounded value elicitation method, while the latter used a fractional factorial design to efficiently generate an attribute and level combination for the improved cook stoves. The study also used various discrete choice models for data analysis and also used models which account for scale and preference heterogeneity. The findings show that the sample households were aware of the effects of using traditional cook stoves and the benefits of using improved cook stoves. However, they were constrained by the availability of the new technology and discouraged by the low-quality of the products that they had used so far. The estimated mean willingness to pay ranged from about 150 Birr to 350 Birr which is lower than the market price of the improved cook stoves. Emission reduction, reducing fire risks, and the durability of the cook stove positively affected its adoption, while price discouraged its use. Higher levels of education, higher incomes, non-farm employment, and having more livestock increased the probability of adopting the new gas stoves. The study recommends that policymakers and product designers should use the mean willingness to pay and marginal rate of substitution for the different attributes as a benchmark for product design and pricing that fit households’ preferences and ability to pay. The lower mean willingness to pay means that a public subsidizing policy is needed for effectively disseminating improved cook stoves in rural Ethiopia.

Money demand, real effective exchange rates, and uncertainty
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This PhD thesis consists of three distinct but interrelated research papers that collectively explore critical aspects of money demand, real effective exchange rates behavior, and uncertainty in different contexts. The first paper examines the nature of money demand in Rwanda and the rationale for the country’s monetary policy shift to inflation targeting in 2019, providing evidence of long-run money demand stability despite uncertainties affecting the global economy, and challenging the view that monetary aggregates should have no role in Rwanda’s monetary policy. The second paper investigates the complex effects of grant revenues on real effective exchange rates in Sub-Saharan African countries, revealing the outcomes of short-run depreciation and long-run appreciation. The last paper assesses how exchange rate regime choice affects the degree and persistence of real effective exchange rate misalignments, showing that, relative to a floating exchange rate regime, fixed and intermediate regimes effectively limit misalignment size, although with higher persistence. Together, these papers offer nuanced insights into the interaction between the money market, uncertainty, external grants, and exchange rate regime, underscoring the need for careful policy consideration to ensure economic stability and competitive currency values.

The effects of lifetime work experience on incidence and severity of elderly poverty in Korea
- 2023
-
Ingår i: Journal of Social and Economic Development. - : Springer. - 0972-5792.
-
Tidskriftsartikel (refereegranskat)abstract
- This study investigates the characteristics that contribute to elderly poverty, mainly focusing on individuals’ lifetime work experience. It adopts the heterogeneous relative poverty line. It calculates the work experience and obtains demographic variables using the Korean Labor and Income Panel Study’s survey data for 2006, 2009, 2012 and 2015. The objective is to estimate poverty among elderly and explain its variations in relation to individual characteristics and lifetime work experience. Poverty is measured in terms of the head count, poverty gap and the poverty severity indices based on monetary dimensions, namely income and consumption. The methodology used in this study is a logit model to explain the incidence of poverty and a sample selection model to analyze the depth and severity of poverty. The results show that an increase in the total work years and a decrease in the gap years between jobs reduce incidence and depth of poverty.

Tidskriftsartikel (refereegranskat)abstract
- This study elaborates on the direct effects of the antecedents of customer trust, corporate image, and the cost of switching service providers. It also examines the indirect effects of these antecedents on customer loyalty and satisfaction through trust, improved corporate image, and lower switching costs. The results of our analysis, which covered a sample of 514 customers in the Kurdistan region of Iraq, show that all the four antecedents studied had both direct and indirect effects on trust, corporate image, switching costs, satisfaction, and loyalty. We also observe that satisfaction is an important mediator between loyalty and the other variables. However, conflict handling has very strong direct and indirect impacts on the other dependent variables. There are some differences between our findings and those of previous research on countries like Turkey, China, and western cultures.

Elaborating on the links between declarative knowledge, procedural knowledge, and employee performance
- 2022
-
Ingår i: SN Business & Economics. - : Springer. - 2662-9399. ; 3:1
-
Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study is to elucidate the links between declarative knowledge, procedural knowledge, and performance in the context of ISO 9001:2015 certification. It develops a model which tests the impact of training and rewarding on employees’ declarative knowledge, procedural knowledge, and motivation. It tests the effects of declarative knowledge, procedural knowledge, and motivation on employees’ contextual and task performance. The study is conducted in Turkey using data collected from 423 employees working in various firms operating in the textiles, food production, and mining sectors. Our results show that although training and rewarding are important antecedents of knowledge and motivation, ISO 9001:2015 certified firms had difficulties in converting these benefits into better employee performance.

Tidskriftsartikel (refereegranskat)abstract
- This study’s aim is investigating the impacts of the determinants of knowledge management on organisational sustainability. It investigates the differences in performance among ISO 9001 certified and non-certified firms. The study uses data collected from 156 employees of various private firms in the Kurdistan Region of Iraq. It uses the partial least squares method to test the hypothesised model and the independent samples t-test toelaborate on the differences between ISO 9001 certified and non-certified firms. The results show that knowledge storage plays a key role in knowledge generation, sharing, and utilisation. It is also observed that knowledge management has a significant impact on organisational sustainability. Firms in the Kurdistan Region of Iraq fail to generate management knowledge due to their weak document storage capacities. This paper discusses the theoretical and practical implications of their weak document storage capacities and makes some suggestions for improving this situation.

Relationship between the Real Estate Sector and the Stock Market in Chinese Provinces
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In China, real estate and the stock market are the two main markets favored by both individual and institutional investors. There is a significant economic link between the two. Therefore, their relationship and long-term and short-term causality can provide good guidance for investors. This paper studies the causality and correlation relationship between the stock market and real estate sector's trading volumes in 31 provinces of China. Its empirical results are based on panel data from 2000 to 2016. Various panel unit root, co-integration, and model specification and estimation tests are carried out. The panel mean group is found to be the most suitable method for the analysis. The study finds that the main industries in different provinces may affect the short-term causal relationship between the real estate sector and the stock market. But in the long-run, the causal relationship between the two is 2-way and stable.
