Substantial empirical evidence shows that suppliers in emerging economies can enhance their technological capabilities through direct learning from technologically advanced foreign competitors. However, suppliers in emerging markets may struggle to learn directly from knowledge about competitors' products that are not widely available on the consumer market. We draw on insights from existing literature, explorative interviews, and anecdotal evidence to hypothesize that firms may resort to in
Optimal monetary policy has traditionally assigned greater importance to stabilizing prices in sectors with stickier prices, based on multi-sector models assuming full information or exogenous information frictions. This paper challenges the prevailing policy prescription by introducing rational inattention with endogenous information acquisition. Interestingly, the optimal policy assigns a smaller weight to sectors with stickier prices when the cost of information acquisition is sufficiently hi
Ambulance offload delays occur when emergency medical service (EMS) personnel are unable to promptly transfer patients to overwhelmed emergency departments. These delays postpone necessary care for the patient and hinder the EMS system from attending to new emergencies. This study introduces a real-time multi-priority patient transfer policy aimed at reducing these delays. We model the patient transfer problem as a stochastic dynamic program based on post-decision states, and develop approximate
Problem definition: As digitization transforms the service sector and empowers service platforms, questions arise about utilizing and disseminating customer information captured by digitization to enhance platform operations. We contribute by investigating how providing customer-related information at the start of a service encounter impacts both service supply and demand in the context of entertainment service platforms. Methodology/ results: We conducted a field experiment on a live-streaming
This paper studies monetary policy design in small open economies with cross-border and input-output linkages. We derive the divine coincidence (DC) Phillips curve linking the output gap to a DC index that weights each sector's inflation by sectoral contents in domestic consumption and exports, and of domestic labor. Output gap targeting can be implemented by stabilizing the DC index, which assigns larger weights to sectors that supply more inputs directly or indirectly to domestic output an
We examine the impact of involuntary job displacement on workers' commuting behavior and its implications for the overall welfare cost of job loss. Using geo-referenced employee-employer data from Germany (2000-2017), we track workers' door-to-door commuting and relocation patterns between home and work. After displacement, workers commute 23.1% (3.38 kilometers) farther to new jobs, and the effect diminishes over time due to job changes rather than home relocation. The simultaneous wage
