Consequences of Linguistic Distance for Economic Growth

This paper advances a new country‐level measure of ethno‐linguistic diversity, making use of Greenberg's definition of diversity by synthesizing information on the share of different ethno‐linguistic groups in a country's population and, more importantly, information on intergroup linguistic distances derived from a recently developed lexicostatistical approach. I show that this measure captures ethno‐linguistic diversity at lower levels of linguistic aggregation. However, unlike the commonly used phylogenetic language tree approach, I found that these distance‐weighted diversity measures continue to have a strong negative statistical association with economic growth that is not sensitive to the underlying resemblance function between ethno‐linguistic groups.     

LIQUIDATION IN LIMIT ORDER BOOKS WITH CONTROLLED INTENSITY

We consider a framework for solving optimal liquidation problems in limit order books. In particular, order arrivals are modeled as a point process whose intensity depends on the liquidation price. We set up a stochastic control problem in which the goal is to maximize the expected revenue from liquidating the entire position held. We solve this optimal liquidation problem for power‐law and exponential‐decay order book models explicitly and discuss several extensions. We also consider the continuous selling (or fluid) limit when the trading units are ever smaller and the intensity is ever larger. This limit provides an analytical approximation to the value function and the optimal solution. Using techniques from viscosity solutions we show that the discrete state problem and its optimal solution converge to the corresponding quantities in the continuous selling limit uniformly on compacts.     

HOW CAN PUBLIC SPENDING HELP YOU GROW? AN EMPIRICAL ANALYSIS FOR DEVELOPING COUNTRIES

Although many studies indicate that both the level and composition of public spending are significant for economic growth, the results in the empirical literature are mixed. This paper suggests that the country sample selection and expenditure classification are important in explaining these conflicting results. The empirical analysis shows that the link between growth and public spending, especially its core component, is strong only for countries with macroeconomic stability and fast GDP per capita growth dynamics, which are also capable of using public funds for productive purposes.     

Equilibrium concepts for time‐inconsistent stopping problems in continuous time

A new notion of equilibrium, which we call strong equilibrium, is introduced for time‐inconsistent stopping problems in continuous time. Compared to the existing notions introduced in Huang, Y.‐J., & Nguyen‐Huu, A. (2018, Jan 01). Time‐consistent stopping under decreasing impatience. Finance and Stochastics, 22(1), 69–95 and Christensen, S., & Lindensjö, K. (2018). On finding equilibrium stopping times for time‐inconsistent markovian problems. SIAM Journal on Control and Optimization, 56(6), 4228–4255, which in this paper are called mild equilibrium and weak equilibrium, respectively, a strong equilibrium captures the idea of subgame perfect Nash equilibrium more accurately. When the state process is a continuous‐time Markov chain and the discount function is log subadditive, we show that an optimal mild equilibrium is always a strong equilibrium. Moreover, we provide a new iteration method that can directly construct an optimal mild equilibrium and thus also prove its existence.     

Endogenous expropriation and political competition

We develop a game-theoretical model in which the politicians can be influenced by means of campaign contributions of special interest groups. If there is no legally binding contract, politicians have a proclivity to divert some contributions for private use. In doing so, they maximize their own utility which depends on expected election-winning premium and amount of funds misappropriated. We study the utility maximizing fraction of expropriation emerging from the equilibrium policy platform and the associated contribution level. We then compare results under alternative scenarios, namely, one single lobby group versus multiple lobby groups and one-sided lobbying versus two-sided lobbying.     

Equilibria of time-inconsistent stopping for one-dimensional diffusion processes

We consider three equilibrium concepts proposed in the literature for time-inconsistent stopping problems, including mild equilibria (introduced in Huang and Nguyen-Huu (2018)), weak equilibria (introduced in Christensen and Lindensjö (2018)), and strong equilibria (introduced in Bayraktar et al. (2021)). The discount function is assumed to be log subadditive and the underlying process is one-dimensional diffusion. We first provide necessary and sufficient conditions for the characterization of weak equilibria. The smooth-fit condition is obtained as a by-product. Next, based on the characterization of weak equilibria, we show that an optimal mild equilibrium is also weak. Then we provide conditions under which a weak equilibrium is strong. We further show that an optimal mild equilibrium is also strong under a certain condition. Finally, we provide several examples including one showing a weak equilibrium may not be strong, and another one showing a strong equilibrium may not be optimal mild.     

CEO–CFO team optimism: Commercial real estate transactions and REIT performance

The managerial optimism literature concentrates on CEOs neglecting other executive team members. We evaluate the interplay of the optimism levels of the CEOs and CFOs of real estate investment trusts, and study their commercial real estate transactions. We find that firms led by optimistic CEO/CFO teams pay 3% more than their peers for their asset acquisitions if cash ratio increases by one percentage point. Our findings also exhibit inferior stock performance by optimistic teams following a transaction. Conversely, diversity in terms of CEO/CFO optimism prevents firms from overpaying, serving as a soft governance mechanism with salience to firm performance.     

Competitive strategies,innovation, and firm performance: an empirical study in a developing economy environment

This paper studies the relationships between competitive strategies, innovation, and firm performance within the context of Turkish manufacturing companies. The data were collected from top management of the firms via Computer Assistant Telephone Interviewing method. One hundred and forty manufacturing firms operating in various sectors including textile, automotive supply, computer and electronics provide the basis for this empirical research. In order to test our model, we employ structural equation modelling using partial least squares. The results show that competitive strategies such as cost-leadership and differentiation can lead to innovation, which, in turn, increase firm performance. Managers implement cost-leadership and differentiation strategies to take part in competitive market conditions; however, they should put additional importance on innovation that plays a significant role as a bridge between competitive strategies and firm performance.

The impact of family life on work efficiency: a study of employed women from different occupational statuses in a metropolitan area in Turkey

The objective of this research was to investigate the family life of employed women from different occupational statuses (white collar, blue collar and professionals) on their work efficiency. The data were obtained from a survey of 300 randomly selected women who work in various offices, universities and factories in Ankara. The findings suggest that women in better conditions (high education, profession, etc.) experienced less negative spillover.
