An Examination of the Quality of Jobs in the Call Center Industry

This paper examines jobs in the information society and the new economy, taking as its focus the call center industry. More specifically, the study analyzes the degree of variability of the quality of call center jobs. In order to achieve this objective, an index of job quality is generated, and an empirical analysis of the characteristics of jobs in call centers is carried out. This allows us to determine the level and variability of quality of jobs in this sector and to establish whether the reality of these jobs is as good as the forecasts for work in the new economy.      

Optimal constrained investment in the Cramer-Lundberg model

We consider an insurance company whose surplus is represented by the classical Cramer-Lundberg process. The company can invest its surplus in a risk-free asset and in a risky asset, governed by the Black-Scholes equation. There is a constraint that the insurance company can only invest in the risky asset at a limited leveraging level; more precisely, when purchasing, the ratio of the investment amount in the risky asset to the surplus level is no more than a; and when short-selling, the proportion of the proceeds from the short-selling to the surplus level is no more than b. The objective is to find an optimal investment policy that minimizes the probability of ruin. The minimal ruin probability as a function of the initial surplus is characterized by a classical solution to the corresponding Hamilton-Jacobi-Bellman (HJB) equation. We study the optimal control policy and its properties. The interrelation between the parameters of the model plays a crucial role in the qualitative behavior of the optimal policy. For example, for some ratios between a and b, quite unusual and at first ostensibly counterintuitive policies may appear, like short-selling a stock with a higher rate of return to earn lower interest, or borrowing at a higher rate to invest in a stock with lower rate of return. This is in sharp contrast with the unrestricted case, first studied in Hipp and Plum, or with the case of no short-selling and no borrowing studied in Azcue and Muler.     

Performance of Moving Average Trading Rules in a Volatile Stock Market: The Russian Evidence

This article examines the profitability of dual moving average crossover (DMAC) trading strategies in the Russian stock market over the 2003–12 period. It contributes to the existing technical analysis (TA) literature by testing, for the first time, the applicability of ordered weighted moving averages (OWMA) as an alternative calculation basis for determining DMACs. In addition, this article provides the first comprehensive performance comparison of DMAC trading rules in the stock market that is known as one of the most volatile markets in the world. The results show that the best trading strategies of the in-sample period can also outperform their benchmark portfolio during the subsequent out-of-sample period. Moreover, the outperformance of the best DMAC strategies is mostly attributable to their superior performance during bearish periods and, particularly, during stock market crashes.     

A comparison of national saving rates in the UK, US and Italy

We develop the approach of Gokhale, Kotlikoff and Sabelhaus [1996. Understanding the postwar decline in US saving: A cohort analysis. Brookings Papers on Economic Activity 0, 315-390], based on the life-cycle model of savings, to decompose the differences in the national saving rates between the UK, US and Italy. Our work suggests that the US saving rate is lower principally because Americans on average retire later. In contrast, the Italian saving rate is higher predominantly because Italians are credit constrained, particularly when young. We also found that demography and the different tax and benefit systems are able to explain little of the cross-sectional differences in saving rates. The study accounts for the possible importance of inter-generational private transfers in determining saving rates.     

Building entrepreneurial inter-firm networks in an emerging economy: the role of cognitive legitimacy

We take an organizational legitimacy perspective and use data from a large-scale nationally representative study on the state of small business in Saudi Arabia, in order to explore the antecedents to the formation of entrepreneurial ventures’ inter-firm networks in the context of an emerging economy (n?=?331). We argue that entrepreneurial ventures need to overcome a threshold of cognitive legitimacy in order to develop inter-firm ties with a diverse set of large, established firms. Results indicate that having a written business plan and a formal organizational structure are positively associated with the diversity of the new venture’s inter-firm network, while the education level of the entrepreneur does not have a significant effect. In addition, the effect of having a formal organizational structure is stronger for younger ventures. Implications are discussed.     

Informal employment in service industries: estimations from nationally representative Labour Force Survey data of Russian Federation

ABSTRACT

As the largest post-Soviet transition economy with substantial labour immigration and a considerable informal-sector Russia serves as an interesting case to study informal employment in the service and non-service economic sectors. The study fills the gap of the lack of empirical papers grounded on the reliable massive individual data. This article discusses almost twenty years’ dynamics of informal employment rates within the service and non-service industries based on the nationally representative Labour Force Survey primary data, collected quarterly for 2010–2015 with a sample size of about 200 thousand respondents per quarter. The unexpected finding is that the rate of informal employment is higher in non-service economic activities. Informal workers in the service sector in Russia are typically male, not very young, without tertiary education, living in urban areas. The paper also provides a comparative regression analysis on the probability of being informally employed in the service and non-service sectors.     

Are price strategies effective in managing demand of high residential water users?

Encouraging water use efficiency and water conservation is one of the primary goals of water utility companies nationwide. This study estimates price elasticity of residential water demand to measure the responsiveness of water use to price changes, particularly for high water users. Household-level water use data for high residential water users from Central Florida were analysed using 3-stage least square (3SLS). Estimated price elasticity ranges between ?0.07 and ?0.14. This price elasticity estimate is below most of the estimates reported in the literature (in absolute value). The results imply that for price strategies to be effective in managing water demand of high residential water users, a significant price increase would be needed. Overall, this study highlights the importance of designing water conservation policies tailored to specific groups of customers, and the importance of using these strategies effectively and fairly for different customer groups.     

Effectiveness of Budgetary Entities

This paper acquaints readers with the practice of effectiveness evaluation in the public sector. The purpose of this paper is to study performance measurement according to the changes in public sector reform by focusing on performance-based budgeting in Russia. This paper suggests that the construction process of performance measurement should be aligned with outputs and outcomes of budget policy. The main research materials for this paper are based on data from a survey and follow-up interviews of budgetary managers and accountants. The survey result sets priorities and weighted some indicators to the measurement of effectiveness in the public sector. The data of this study were not large, but the study led to understanding how effectiveness is seen by budgetary managers and how measurement systems should be structured. Texts and contents from different sources such as financial annual reports and budgetary entities＇ websites provided insightful and interesting findings.     

Properties of emerging organizations: An empirical test

The process of new venture creation is central to the field of entrepreneurship. The effects of initial organizing have a direct influence on survival, yet empirical examination of the dimensions of emergent organizations is limited. Using longitudinal data on nascent entrepreneurs, this paper empirically tests four properties of emerging organizations-intentionality, resources, boundary and exchange- and their effect on likelihood of continued organizing [Katz, J., Gartner, W.B., 1988. Properties of emerging organizations. Academy of Management Review 13(3), 429–441]. Our results suggest that all four properties are necessary for firm survival in the short-term and those firms that organize more slowly are more likely to continue to organize. Further, nascent ventures in which intentionality preceded the other organizing properties were not significantly more likely to continue in the organizing effort. Our results suggest an extension of the original Katz and Gartner [Katz, J., Gartner, W.B., 1988. Properties of emerging organizations. Academy of Management Review 13(3), 429–441] framework.
