Captive diffusions and their applications to order-preserving dynamics
(Royal Society Publishing, 2020-09-30)We propose a class of stochastic processes that we call captive diffusions, which evolve within measurable pairs of cadlag bounded functions that admit bounded right-derivatives at points where they are continuous. In full ... -
Captive jump processes for bounded random systems with discontinuous dynamics
(Elsevier, 2024-01)Stochastic captive jump processes are explicitly constructed in continuous time, whose non-linear dynamics are strictly confined by bounded domains that can be time-dependent. By introducing non-anticipative path-dependency, ... -
Carrier selection for Less-Than-Truckload (LTL) shipments
(Elsevier, 2021)This chapter reviews the basics of carrier selection for less-than-truckload (LTL) shipments. First, the impacts of LTL carrier selection on various strategic, tactical, and operational supply chain planning decisions are ... -
The case against active pension funds: evidence from the Turkish private pension system
(Elsevier, 2015-06)Using data on private Turkish pension funds we show that most active managers are not able to provide performance beyond what could be achieved by passive indexing. The average fund beats its benchmark by only 26 basis ... -
Cash flow news, discount rate news, and momentum
(Elsevier, 2016-11)We examine the effect of aggregate cash flow news and discount rate news on momentum returns. We find that momentum profits are higher following aggregate positive cash flow news, even in down markets or low sentiment ... -
Catching up or drifting apart: convergence of household and business credit in Europe
(Elsevier, 2017)We provide evidence for convergence in the levels of household and business credit across European countries. The process is particularly strong for the transition countries that have a low initial level of private credit ... -
CEO overconfidence, reit investment activity and performance
(Wiley, 2015)This is the first article to study the effects of overconfidence on trading activity and performance in real estate. The article looks at Real Estate Investment Trusts (REITs), as their investments and divestments can be ... -
Characterizing the TTC rule via pair-efficiency: A short proof
(Elsevier, 2024-01)In the object reallocation problem, Ekici (2023) showed that Top Trading Cycles (TTC) is the unique rule that is strategyproof, individual-rational, and pair-efficient. We provide a short proof of this characterization result. -
Client-server versus peer-to-peer
(Boğaziçi Üniversitesi İktisadi ve İdari Bilimler Fakültesi, 2016)This study identifies optimal transmission mechanisms for a video streaming service in a peer-to-peer network structure under different payment mechanisms: pay as you watch and pay upfront. We calculate a uniform, feasible ... -
Combining big data and lean startup methods for business model evolution
(Springer, 2017-12)The continued survival of firms depends on successful innovation. Yet, legacy firms are struggling to adapt their business models to successfully innovate in the face of greater competition from both local and global ... -
Communicating forecasts: the simplicity of simulated experience
(Elsevier, 2015-08)It is unclear whether decision makers who receive forecasts expressed as probability distributions over outcomes understand the implications of this form of communication. We suggest a solution based on the fact that people ... -
Company innovation system: a conceptualization
(Operations and Information Management Group, Aston Business School, Aston University, 2018-04-25)We conceptualize the company as an innovation system that consists of components, relationships and attributes, with the purpose to produce innovation. The systems approach to innovation has received limited attention at ... -
A comparison of optimal policy rules prior to and during inflation targeting: empirical evidence from Bank of Canada
(Taylor & Francis, 2017)We examine policy rules that are consistent with inflation targeting (IT) framework in a small macroeconomic model of the Canadian economy. We set up an optimal linear regulator problem and derive policy rules to compare ... -
Competitive implications of software open-sourcing
(Elsevier, 2012-12)This paper is concerned with the economic trade-offs associated with open-sourcing, the business strategy of releasing free open-source versions of commercial software products. The effect of the release of open-source ... -
Composing offer sets to maximize expected payoffs
(Digital Commons, 2016)Firms are increasingly using clickstream and transactional data to tailor product offerings to visitors at their site. Ecommerce websites have the opportunity, at each interaction, to offer multiple items (referred to as ... -
Computational comparison of five maximal covering models for locating ambulances
(Wiley, 2009-01)This article categorizes existing maximum coverage optimization models for locatingambulances based on whether the models incorporate uncertainty about (1) ambulanceavailability and (2) response times. Data from Edmonton, ... -
A concave security market line
(Elsevier, 2019-09)We provide theoretical and empirical arguments in favor of a diminishing marginal premium for market risk. In capital market equilibrium with binding portfolio restrictions, investors with different risk aversion levels ... -
The conceptual difference really matters: Hofstede vs GLOBE’s uncertainty avoidance and the risk-taking behavior of firms
(Emerald Publishing Limited, 2019-12-05)Purpose In spite of the common label, uncertainty avoidance (UA) across Hofstede and GLOBE models has been found to be negatively correlated and capture distinct concepts. Nevertheless, the empirical research focusing on ... -
Conceptualizing a research paradigm for multi-objective modelling in supply chain management
(Wiley, 2015)The primary objective of this paper is to offer a particular research paradigm framework that takes into consideration ontological, epistemological, methodological and axiological assumptions for a more meaningful and ... -
Configurations of digital platforms for manufacturing: An analysis of seven cases according to platform functions and types
(Springer, 2023-06-24)We analyze organizational configurations of digital platforms for manufacturing according to two dimensions: platform functions and platform types. Platform functions refer to the organizational functions of platforms: ...
