Income Mobility in the Developing World

This chapter examines income mobility in developing countries. We start by synthesizing findings from the available evidence on relative mobility and poverty dynamics. We then describe evidence on economic mobility obtained via synthetic panels constructed from cross-section data. We echo earlier literature in pointing to substantial movement across income classes by households over time—poverty is not inevitably a chronic condition. However, less clear are the factors driving the observed ‘churning’. In an attempt to make headway, we consider the story of economic mobility in one village in northern India over seven decades. We describe patterns of poverty dynamics and economic mobility in the village, and we highlight some of the processes that have been important in driving these patterns. While this in-depth study does not permit inferences to broader populations, it may provide a reference point against which findings from studies elsewhere can be compared.

Determinan Pengangguran Terdidik Lulusan Universitas di Pulau Jawa

This study aims to determine the factors that influence educated unemployment in Java. The data used in this study is secondary data using quantitative methods. Data analysis uses panel data analysis which is a combination of time series and cross-section data. The time-series data uses data for the 2015-2019 period and cross-section data from 6 provinces on the island of Java. The results showed that simultaneously all variables had a significant effect on the level of educated unemployment. While partially shows that the variable level of education and PMDN have a significant positive impact on educated unemployment, and the UMR variable has a significant negative impact on educated unemployment.

A Fit to the Available e+e-→Λc+Λ-c- cross Section Data Nearby Production Threshold by Means of a Strong Correction to the Coulomb Enhancement Factor

There are two available sets of data on the e+e−→Λc+Λ¯c− cross section at energies close to the production threshold, collected by the Belle and by the BESIII Collaborations. The measurement of the former, performed by means of the initial state radiation technique, is compatible with the presence of a resonance, called ψ(4660), observed also in other final states. On the contrary, the latter is measured an almost flat and hence non-resonant cross section in the energy region just above the production threshold, but the data stop before the possible rise in the cross section for the resonant production. We propose an effective model to describe the behavior of the data near this threshold, which is based on a Coulomb-like enhancement factor due to the strong interaction among the final state particles. In the framework of this model, it is possible to describe both datasets.

A new method for obtaining a Born cross section using visible cross section data from e+e− colliders

In this paper, we propose a new method for obtaining a Born cross section using visible cross section data. It is assumed that the initial state radiation is taken into account in a visible cross section, while in a Born cross section this effect is ommited. Since the equation that connects Born and visible cross sections is an integral equation of the first kind, the problem of finding its numerical solution is ill-posed. Various regularization-based approaches are often used to solve ill-posed problems, since direct methods usually do not lead to an acceptable result. However, in this paper it is shown that a direct method can be successfully used to numerically solve the considered equation under the condition of a small beam energy spread and uncertainty. This naive method is based on finding a numerical solution to the integral equation by reducing it to a system of linear equations. The naive method works well because the kernel of the integral operator is a rapidly decreasing function of the variable x. This property of the kernel leads to the fact that the condition number of the matrix of the system of linear equations is of the order of unity, which makes it possible to neglect the ill-posedness of the problem when the above condition is satisfied. The advantages of the naive method are its model independence and the possibility of obtaining the covariance matrix of a Born cross section in a simple way.It should be noted that there are already a number of methods for obtaining a Born cross section using visible cross section data, which are commonly used in e+e− experiments. However, at least some of these methods have various disadvantages, such as model dependence and relative complexity of obtaining a Born cross section covariance matrix. It should be noted that this paper focuses on the naive method, while conventional methods are hardly covered. The paper also discusses solving the problem using the Tikhonov regularization, so that the reader can better understand the difference between regularized and non-regularized solutions. However, it should be noted that, in contrast to the naive method, regularization methods can hardly be used for precise obtaining of a Born cross section. The reason is that the regularized solution is biased and the covariance matrix of this solution do not represent the correct covariance matrix of a Born cross section.

The Determinants of the Value of Mahr in Muslim Societies: Evidence from the Indonesian Family Life Surveys

This paper aims to analyze the factors that determine the value of mahr in Muslim societies. The analysis is based on an ordinary least squares (OLS) regression with pooled cross-section data from the last three waves of the Indonesian Family Life Surveys (IFLS). The main finding is that socioeconomic status in the forms of groom’s ownership of assets and education level matters most for the value of mahr. This finding holds for regression with full sample as well as subsamples, i.e. couples whose groom is Javanese, couples whose groom is non-Javanese, couples whose bride is Javanese and couples whose bride is non-Javanese. Socioeconomic status in the form of bride’s education level also matters for the value of mahr with some exceptions. The other finding is that perceived risk of divorce as represented by differences in the socioeconomic status of a marrying couple do not have a significant effect on the value of mahr. The effect of physical appearances in the form of bride’s height is at best not robust and subject to the sample or subsample included. These findings can be useful as a reference to make marriage decisions in the future or to evaluate the ongoing practices for possible reforms.

Management restructuring on distress firm in Indonesia

Companies experiencing financial distress will try to solve these problems with various improvement efforts. One of the efforts that can be done is to carry out management restructuring, namely management changes. This study focuses on the management restructuring strategy on manufacturing companies that experience a decrease in performance, with the proportion of Earning Before Interest and Tax which decreased for two or more consecutive years period 2010 to 2020. The reason for taking this period is to capture the period after the 1997 crisis until the occurrence of global crisis in 2008. This study aims to examine the effect of ownership structure in choosing management turnover restructuring. The data used is cross-section data and processed using logistic regression with Stata. The results of this research simultaneously show that insider ownership, institutional ownership, family ownership, and corporate characteristic variables have an impact on the management restructuring decision. This study proves that the ownership structure mechanism affects the choice of management restructuring in distressed companies in Indonesia.

Pengaruh Pengendalian Internal dan Kompetensi Terhadap Pencegahan Kecurangan Pengelolaan Dana Desa di Kecamatan Kumpeh Ulu Kabupaten Muaro Jambi

There are challenges in implementing village funds during this pandemic because the amount of absorption of village funds is used to address the conditions for handling Covid 19. The implemention of the distribution and absorption of this budget is influenced by inhibiting factors that become challenges in the implementation of village development. Internal factors in the village government are important to prevent fraud in the absorption of village funds. Therefore, one of the objectives of this study is to analyze the effect of internal control and competence on fraud prevention in Kumpeh Ulu sub-district, Muaro Jambi district. This research is causality research design. Causality research design is a type of research that is used for the purpose of testing the influence, relationship or impact of variables, the type of cross section data used and the primary data souces. This research took place from june to august 2021. The data analysis technique used SEM-PLS. The results of this study indicate that internal control and competence have an effect on fraud prevention.

ANALYSIS OF MONETARY FACTORS ON THE INCOME OF COASTAL FISHERMAN’S IN THE COVID-19 WEST ACEH REGENCY

This research aimed to analyze fisherman’s income according to monetary factors during covid-19 pandemic in coastal areas of West Aceh Regency in Aceh Province, Indonesia. This research applied cross-section data over 2021 by utilizing descriptive quantitative research and OLS model analysis (Ordinary Least Square). Research revealed monetary factors in term of the inflation of groceries price had negative influenced to the fisherman income at West Aceh Regency, mean while the variable of diesel price had positive influenced to fisherman income. During covid-19 pandemic, there was the increasing of groceries price (inflation) at 1,06 times or the consumer price index (CPI) of groceries price at 106 percent but the price of diesel was still same as before covid-19 pandemic because fisherman used subsidized fuel at Rp 5.150/liter. However, the quota of subsidized diesel did not fulfill the fisherman needs so that they must buy non subsidized diesel. It was impacted on the fishing operational cost which was bigger than fisherman income. Moreover, during covid-19 pandemic the average of fisherman income decrease at IDR 1.500.000-IDR 3.000.000 each trip compared with before covid-19 pandemic at IDR 5.000.000- IDR 7.000.000 each trip. It was caused by low fish price which was caused by the decreasing of fish demand.
