Silicon Valley Bank Failure

The Silicon Valley Bank (SVB) crisis was the third-largest US bank failure in history, occurring in March 2023 after a run on deposits led to its seizure by regulators. The crisis was triggered by the bank’s large portfolio of long-term, low-yield securities that lost significant value when the Federal Reserve raised interest rates to control inflation. This, combined with a downturn in the tech sector and widespread panic, caused customers to rapidly withdraw funds, prompting the bank to sell assets at a loss, and ultimately leading to its collapse.

Social Benefit

The positive impact of an action, policy, or project on society as a whole. Unlike private benefits, which accrue directly to an individual or a specific organization, social benefits are broader and often affect a large segment of the population or the entire community.

This is the phenomenon driven by such forces as markets and regulation whereby individuals, households, businesses, and other agents make choices. For example, households may sort across neighborhoods according to their wealth and their preferences for public goods, social characteristics, and commuting opportunities. Individuals may sort in marriage markets according to looks, wealth, status, education, among other factors. Companies may sort based on labor quality and quantity, transportation costs, regulations, taxes, and so on.

Spatial Strategic Competition

There are many forms of potential strategic behavior among incumbent firms and potential entrants into a market. Depending on conditions, incumbents may have an incentive to respond pre-emptively to threatened entry or in a particular manner once entry has occurred. In such cases, the incumbent’s intent is to favorably shape the structure of market competition. The (potential) entrant, in turn, faces a decision as to how to best respond to the incumbent’s behavior, and indeed the incumbent’s action likely builds expectations of this reaction into their initial strategy. Spatial models can provide insights into resource allocation and price determination.

What is Newsworthy? Theory and Evidence


Statistically Significant

A result in data analysis or hypothesis testing that is unlikely to have occurred due to random chance, based on a predetermined significance level (e.g., 5%). A statistically significant finding provides evidence to reject the null hypothesis, suggesting that the observed effect is real and not merely a result of random variation in the data.
