Some economists argue that corruption can contribute to economic growth by bypassing red tape and financing issues. Using data from China's anti-corruption campaign in 2012, Mariassunta Gianetti shows that small, young - and potentially more productive - firms tend to perform better when corruption is cut. This video was recorded at CEPR's Third Annual Spring Symposium.

It is commonly assumed that policing in Britain cannot keep up with rising crime levels. Richard Disney shows that, while some police forces in the country do better than others, in recent years the average performance of police forces has not changed. He also discusses key challenges British police face today, from the nature of crimes they must tackle to their labour demand.

Private equity funds are usually illiquid for invested limited partners over a fixed period of time. But, as the Global Crisis has shown, sometimes partners may need to cash out early. Enrique Schroth discusses how the cost of doing so, in terms of the discount partners pay on their investment, can be substantial. One quarter to one third of the variation in the discount paid for an early exit can be attributed to the amount of liquidity in the economy.

Some research suggests violence towards minority groups is exacerbated during times of economic stress. Mark Koyama discusses his work on when the tendency to target minority groups becomes manifest. Using 1000 years' date on pogroms across Europe, he shows that the likelihood of scapegoating minority groups increased by 50% in seasons when harvests were likely to be poor.

Although average wealth in India has risen in recent years, calorie consumption has paradoxically fallen. Josephine Duh and Dean Spears explain that Indians are eating less despite being richer because disease rates are slowly declining, meaning that nutrition from food is extracted more efficiently.

Superstar firms like Facebook and Tesla make a substantial difference to overall industry productivity. In his research, Dong Lou asks whether they also impact students’ choices of degree majors. Using data on students' college major choices and the stock returns and media coverage of relevant companies in the US, he shows that firm performance had a positive effect on encouraging students to choose relevant majors. But the relevant labour demand in those industries has not risen accordingly, which has depressed wages.

Dirk Jenter 12 July 2018

The ways in which the size and nature of a company's board of directors affects its performance are complex. Using a dataset of German firms, Dirk Jenter shows that profitability and stock market valuations decrease as board sizes increase. Ill-designed board size regulations can therefore negatively impact a firm's performance.

Andrew Ellul 05 July 2018

Systemic risk has been a cause for growing concern since the onset of the Global Crisis. Andrew Ellul explains his research on the lending side of systemic risk creation, which address the types of investments financial institutions make. These investments have shifted towards equity markets, which are riskier and less liquid, and more interconnected - all of which amplifies risk in crisis.

The social benefits of higher education are as important as the improved job opportunities and lifetime earnings it might provide. Shqiponja Telhaj explains how higher education is linked to improved economic growth, health, and wellbeing - with the benefits spilling over from those that received higher education to those that did not.

Gill Wyness 02 July 2018

A central motivation for getting a degree is to increase one's job prospects. Gill Wyness discusses how having a degree does indeed increase lifetime earnings for men and women, and how the UK's income-contingent student loan system ensures that the burden of repayment only increases as incomes rise. This video was recorded at the 2018 RES Conference.
