Large-scale semidefinite programming with graphics processing units
Semidefinite programming (SDP) provides a powerful framework in applied mathematics with applications spanning optimization, machine learning, quantum computing, and beyond. However, the computational cost of solving large-scale SDP problems remains a significant practical limitation. We break this long-standing computational bottleneck through a synergistic codesign of low-rank algorithms and graphics processing unit (GPU) architectures, developing accelerated first-order methods that leverage

Leveraging Network Effects for Connected Products: Strategies and Implications for the Value Chain
This paper examines how a value chain can strategically harness network effects in connected products. We consider a representative two-tier value chain, in which a manufacturer sells a connected product through a retailer. Consumers derive both a stand-alone value and a network benefit, which increases with the size of the user base and the strength of the network effect. We investigate two strategies to effectively leverage these network effects. First, we analyze network expansion through see

The 2003 U.S. Dividend Tax Cut, Small Business Loan Supply, and the Real Economy
This paper examines the credit supply-side effect of the U.S. 2003 dividend tax cut on the real economy through the banking sector. We show that C-corporation banks (treatment group), particularly those capital-constrained, increase the supply of small business loans more than S-subchapter banks (control group) following the tax cut, aligning with the old view of dividend taxation and the supply-side effect rooted in credit rationing. Such an enhanced small business loan supply stemming fro

Dynamic Pricing for Two-Sided Marketplaces with Offer Expiration
We consider a two-sided marketplace in which a market operator sells services to clients and buys services from vendors. The market operator determines the prices dynamically for both clients and vendors. Services are transacted in discrete units called jobs, and the jobs are characterized by their types, service deadlines, client prices, and vendor prices. Jobs are submitted by clients to the marketplace, and the market operator then lists the available jobs. Vendors can view the available jobs

Data-Driven Asset Selling
Online asset-selling businesses, such as used cars and real estate platforms, have experienced remarkable growth in recent years. Unlike general retail operations, which make decisions at the stock-keeping unit level, asset selling operates at the individual unit asset level. Practical operational constraints (e.g., infrequent price adjustments within a limited timeframe) set asset-selling platforms apart from general retail. Further complicating decision-making are real-world uncertainties, suc
