Staggering and Synchronization in Price-Setting: Evidence from Multipro-duct Firms

Most of the theoretical literature on price-setting behavior deals with the special case in which only a single price is changed. At the retail-store level, at least, where dozens of products are sold by a single price-setter, price-setting policies are not formulated for individual products. This feature of economic behavior raises a host of questions whose answers carry interesting implications. Are price setters staggered in the timing of price changes? Are price changes of different products synchronized within the store? If so, is this a result of aggregate shocks or of the presence of a store- specific component in the cost of adjusting prices? Can observed small changes in prices be rationalized by a menu cost model? We exploit the multiproduct dimension of the dataset on prices used in Lach and Tsiddon (1992a) to explore several of these and other issues. To the best of our knowledge this is the first empirical work on this subject.

Equity crowdfunding and early stage entrepreneurial finance: damaging or disruptive?

Equity crowdfunding (ECF) offers founders of new ventures an online social media marketplace where they can access a large number of investors who, in exchange for an ownership stake, provide finance for business opportunities that they find attractive. In this paper, we first quantify the evolution of the ECF market in the UK, the world leader, as well as the benign regulatory environment. ECF already represents more than 15% of British early stage entrepreneurial finance. We then use qualitative methods to explore three research questions. First, do these large financial flows via ECF platforms supplement or merely divert more traditional forms of funding for entrepreneurs? Second, do investors understand and appropriately evaluate the risks that they are bearing by investing in this new asset class? Finally, does ECF finance bring with it the spillovers, e.g. advice and guidance critical to entrepreneurial success, associated with other sources of funding such as Venture Capital? Our study is based on extensive interviews with investors, entrepreneurs (including some who chose not to use ECF in favour of traditional funding sources) and regulators. We conclude that ECF provides real additionality to the sources of entrepreneurial finance while not bringing major new risks for investors. This suggests other jurisdictions might consider implementing the British “principles based” regulatory framewor

Expanding the international trade and investment policy agenda: the role of cities and services

We explore the public policy implications of two new, significant, and inter-related global phenomena. First, the rising share of services, particularly innovation-driven digital and knowledge-based services, in foreign trade and multinational enterprise activity; and second, the increasingly important role of global cities as home and hosts to these activities. Our framework distinguishes between national economic policies to promote trade and FDI, referred to as economic diplomacy, and comparable policies originating in cities, referred to as city diplomacy. National economic diplomacy has traditionally promoted trade and investment in goods, often through trade agreements and promotion agencies, and we explore the limitations of these tools as trade in services becomes more important. However, we also note that trade in services, particularly innovation-driven services, is concentrated in global cities, and traded between them, often within MNEs. We conclude that national policies on trade and investment cannot be divorced from innovation and knowledge strategies, and that these strategies cannot be divorced from cities. We emphasize that national economic diplomacy should be better aligned with city diplomacy. We also discuss how the transition to stronger city diplomacy may have consequences for firms and their strategies for corporate diplomacy

Using Multigroup-Multiphase Latent State-Trait Models to Study Treatment-Induced Changes in Intra-Individual State Variability: An Application to Smokers\u27 Affect

Sometimes, researchers are interested in whether an intervention, experimental manipulation, or other treatment causes changes in intra-individual state variability. The authors show how multigroup-multiphase latent state-trait (MG-MP-LST) models can be used to examine treatment effects with regard to both mean differences and differences in state variability. The approach is illustrated based on a randomized controlled trial in which N = 338 smokers were randomly assigned to nicotine replacement therapy (NRT) vs. placebo prior to quitting smoking. We found that post quitting, smokers in both the NRT and placebo group had significantly reduced intra-individual affect state variability with respect to the affect items calm and contentrelative to the pre-quitting phase. This reduction in state variability did not differ between the NRT and placebo groups, indicating that quitting smoking may lead to a stabilization of individuals\u27 affect states regardless of whether or not individuals receive NRT

Cultural, administrative, and economic proximity between the UK and Canada should be good for trade

Economists place considerable emphasis on the role of (geographic) distance in explaining the pattern of international trading relationships. Using a metaphor from Newtonian physics, trade and foreign direct investment (FDI) between countries are often seen as being driven by the forces of gravity, encapsulated in the relative size of their markets and the distance between their economies. Moreover, as shown in a previous brief, geographic distance is expected to have non-linear effects; as countries become further away, their trading relationship is expected to become less intense at an increasing rate. Building on that, in this post, Saul Estrin, Angelina Borovinskaya, Christine Cote, and Daniel Shapiro provide a more fine-grained perspective on gravity effects which takes into account administrative and economic differences as well as cultural factors. They argue that cultural, administrative, and economic proximity between the UK and Canada should be good for trade
