Consumer protection | EPFL Graph Search

Consumer protection is the practice of safeguarding buyers of goods and services, and the public, against unfair practices in the marketplace. Consumer protection measures are often established by law. Such laws are intended to prevent businesses from engaging in fraud or specified unfair practices to gain an advantage over competitors or to mislead consumers. They may also provide additional protection for the general public which may be impacted by a product (or its production) even when they are not the direct purchaser or consumer of that product. For example, government regulations may require businesses to disclose detailed information about their products—particularly in areas where public health or safety is an issue, such as with food or automobiles. Consumer protection is linked to the idea of consumer rights and to the formation of consumer organizations, which help consumers make better choices in the marketplace and pursue complaints against businesses.

Essays in Financial Economics

This thesis consists of three chapters that study separate subjects in the area of corporate governance and financial intermediation. In the first chapter, I study a protectionist anti-takeover law introduced in 2014 in France that covers a subset of all firms in the economy. The law decreased affected firms' likelihood of becoming the target of a merger or acquisition and had a negative impact on shareholder value. There is no evidence that management of those firms subsequently altered firm policies in its interest. Investment, employment, wages, profitability, and capital structure remain unchanged. The share of annual CEO compensation consisting of equity instruments increased by 8.4 percentage points, suggesting that boards reacted to the loss in monitoring by the takeover market by increasing the pay-for-performance sensitivity. In the second chapter, which is co-authored work with Rüdiger Fahlenbrach, we conduct a detailed analysis of investors in successful initial coin offerings (ICOs). The average ICO has 4,700 contributors. The median participant contributes small amounts and many investors sell their tokens before the underlying product is developed. Large presale investors obtain tokens at a discount and flip part of their allocation shortly after the ICO. ICO contributors lack the protections traditionally afforded to investors in early stage financing. Nevertheless, returns nine months after the ICO are positive on average, driven mostly by an increase in the value of the Ethereum cryptocurrency. In the third chapter, which is joint work with Christoph Herpfer, we investigate how bankers use information from lending relationships to help borrowers combine resources in strategic alliances. Firms that have borrowed from the same banker or share an indirect connection through a network of bankers are significantly more likely to enter an alliance. Consistent with bankers overcoming informational frictions, their ability to facilitate alliances decreases with network distance, and is stronger for opaque borrowers. Firms connected to more potential partners via banker networks enter more alliances. These alliances are associated with positive announcement returns and brokering banks are more likely to receive future underwriting mandates.

Fiscal Policy, Relative Prices and Net Exports in a Currency Union

Christian Pröbsting

This paper studies the effects of fiscal policy on net exports, the terms of trade and expenditure switching. Using data on government spending and consumption taxes for twelve euro area countries over 1996 to 2018, it shows that fiscal austerity shocks improve net exports. This improvement in the trade balance is driven by falling imports while exports do not respond; export and import prices co-move and the terms of trade does not deteriorate in response to an austere shock. The empirical evidence confirms asymmetric expenditure switching, as domestic consumers switch towards domestically produced goods while foreign consumers fail to do so. In a second step, we rationalize these findings in a multi-product small-open DSGE model that features GHH preferences, a non-traded consumption good and pricing to market.

The Advent of the Sharing Culture and its Effect on Product Pricing

Maryam Razeghian Jahromi, Thomas Alois Weber

Empirical observations suggest that consumers' propensity towards sharing varies with culture and the individuals' socio-demographic characteristics. In an economy with overlapping generations of heterogeneous consumers, we study optimal dynamic selling by a durable-goods monopolist in equilibrium. Feasible dynamic pricing strategies include second-degree price discrimination offering intertemporal consumption bundles in the form of rental and/or purchase options. We find that as the population's peer-trade propensity increases, possibly due to a cultural shift from private ownership to collective consumption, the durable-goods monopolist's optimal strategy shifts from unbundling (offering exclusively rentals), via mixed bundling (offering the options of rental and purchase side-by-side), to pure bundling (offering purchase only). We show that an increase in peer-trade propensity has an ambiguous effect on the firm's profit. Cultural shifts from low to high peer-trade propensity may be delayed by a firm's attempts to artificially disable sharing markets by offering overly low rental rates. However, beyond a certain threshold of peer-trade propensity, the firm prefers a cultural transition to an access-based economy. The underlying reason is that the asset base of a sharing economy ultimately depends on the firm's output, so that a portion of the anticipated rents from sharing can be captured by the durable-goods monopolist.
