Social learning often occurs between groups with different levels of experience. Yet little is known about the ideal behavioral rules in such contexts. Existing insights only apply when individuals learn from each other in the same group. In this paper, we close this gap and consider two groups,...

This study focuses on discovered versions of coordination games with unawareness, and proposes a novel solution concept under unawareness named a successful-coordination equilibrium. In games with unawareness, coordination might fail because the models assume that agents are unaware of their...

The paper analyzes under what circumstances policymakers experiment with policies with uncertain outcomes, when they prefer to imitate policies initiated in other countries, and when they prefer to coordinate policies internationally. Policymakers have private costs of active policies and...

We compare how well agents aggregate information in two repeated social learning environments. In the first setting agents have access to a public data set. In the second they have access to the same data, and also to the past actions of others. Despite the fact that actions contain no...

We construct an endogenous growth model with random interactions where firms are subject to distortions. The TFP distribution evolves endogenously as firms seek to upgrade their technology over time either by innovating or by imitating other firms. We use the model to quantify the effects of...

Objective: The objective of the article is to identify challenges and success factors related to the imitation of the digital platform business model in other industries. Research Design & Methods: We based our research on a single case study of an extra-industry imitation performed by a digital...

From a firm’s perspective two competing forces are driving the decision to invest in innovation. On the one hand, innovative performance is an important driver of profitability and growth. On the other hand, investments in innovation suffer from negative externalities, i.e. spillovers to other...

The debate on whether COVID-19 vaccine patents are slowing down the pace of vaccination and the recovery from the crisis has brought the optimal design of pharmaceutical patent policy to the fore. In this paper we evaluate patent policy in the US pharmaceutical industry. We estimate the effect...

In this paper, we empirically examine how export pioneers emerge and how they are related to product creators/innovators, utilizing a rich plant-product level dataset from the Korean manufacturing sector for the period of 1990-1998. Our analysis covers the process from the appearance of product...

Market players in the energy sector transition are heterogeneous, have bounded rationality and are influenced by their own past failures, as well as imitating the successes of their competitors. However this agent heterogeneity and complex behaviour in investment choices is not taken into...

Many platforms operating online marketplaces sell their own products alongside those of third-party sellers, and may use marketplace data on the demand for third-party products to inform the launch of their own products. To evaluate the anti-competitive implications of this practice, we model...

We analyze the effects on consumers of an extreme policy experiment -- Napsterizing' pharmaceuticals -- whereby all patent rights on branded prescription drugs are eliminated for both existing and future prescription drugs without compensation to the patent holders. The question of whether this...

We examine the role of latecomers’ optimal resource allocation between innovation and imitation in latecomers’ catch-up under diverse technological regimes. Building on Nelson and Winter (1982), we develop computational models of technological leadership change. The results suggest that...

In the last two decades, the world has witnessed the rise of Chinese innovation. China, once a manufacturing hub for the West, has become a major player in the development of many new technologies. We assess how foreign knowledge spillovers spurred this transformation. To this end, we assemble a...

The debate between the North and the South about the enforcement of intellectual property rights in the South is examined within a dynamic general equilibrium framework in which the North innovates new products and the South imitates them. A welfare evaluation of a policy of tighter intellectual...

Defensive innovations in developed countries can explain the empirical phenomenon that openness towards trade with less-developed countries does not necessarily induce a substantial increase in the wage differential and trade volumes. Building on step-by-step innovations as introduced by Aghion...

The extant service innovation literature suggests the high cost of an information search, when evaluating a new service provider, creates switching costs that hold customers hostage, allowing first-movers to recoup their investments and sustain an advantage. We utilize Transaction Cost Economics...

From a firm’s perspective two competing forces are driving the decision to invest in innovation. On the one hand, innovative performance is an important driver of profitability and growth. On the other hand, investments in innovation suffer from negative externalities, i.e. spillovers to other...

This paper investigates the choice of an intellectual protection regime for a process innovation. We set up a multi-stage model in which choosing between patent and trade secrecy is affected by three parameters: the patent strength defined as the probability that the right is upheld by the...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

We introduce a generalized theoretical approach to study imitation models and subject the models to rigorous experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to different informational assumptions, not to different...

In this article, a modelling framework for the information transmission between agents in an evolutionary game setting is proposed. Agents observe traits which reflect past and present behaviour and success of other agents. If agents imitate more successful agents based on these traits, the...

We examine competition for foreign direct investment when governments compete in tax incentives along with intellectual property rights (IRPs) protection. Higher IPRs result in a lower probability of the multinational enterprise (MNE) being imitated and thus higher expected profits and tax...

While exchanges and regulators are able to observe and analyze the individual behavior of financial market participants through access to labeled data, this information is not accessible by other market participants nor by the general public. A key question, then, is whether it is possible to...

In this paper, we develop a new dynamic model of optimal investments in R&D and manufacturing for a technological leader competing with a large number of identical followers on the market of a technological product. The model is formulated in the form of the infinite time horizon stochastic...

Luigi Barone’s famous curve offers an excellent framework for the study of the microeconomic and macroeconomic implications of innovation and imitation. However, neither Barone nor his epig- ones have been able to sufficiently "exploit" his contribution to date. Complementing his analysis of...

The scope of this paper is to investigate whether imitation strategies adopted by startups are effective in the pursuit of enhanced entrepreneurial innovation. To this end, a literature review was carried out in order to develop a research framework with factors related to imitation predicting...

This paper develops a North-South trade model with heterogeneous labour and horizontally differentiated products and compares the implications of two policies: Southern intellectual property rights (IPRs) and Northern immigration policy that aims to attract Southern talent as means of preempting...

We find strong evidence that imitation to the leader in an uncertain environment provides short-term early success without enhancing long-term survival. Using a unique setting in cryptocurrencies where Bitcoin has been the centre focus, we define copycats as cryptocurrencies that have a name...

We study an infinite-horizon cumulative innovation model, in which patents are characterized bytheir length and the likelihood of being ruled valid in a patent infringement litigation. Strengtheningpatent protection via a greater validity or length has two opposing effects on innovation: 1)...

We model and experimentally evaluate the trade-off between innovation and imitation commonly faced by firms and individuals. Innovation involves searching for a high payoff opportunity, but paying a cost to do so. Imitation involves avoiding the search cost and copying the most successful payoff...

We introduce a novel methodology to identify copycat behavior in mutual funds. We find that imitation is pervasive in the mutual fund industry. While most copycats underperform, a small number are 'smart imitators'. We find that funds at the high and low ends of the Copycat Score range...

Imitation is ubiquitous, yet the comparative efficacy of imitation strategies is poorly understood. A popular imitation strategy, sometimes called benchmarking, “mixes-and-matches” the practices common to leading firms. Using computational models, we compare benchmarking to the...

This study examines when and how latecomers can surpass incumbents in technological capabilities with a focus on the role of technological opportunity. There is disagreement in theoretical prediction and evidence on whether technological opportunity is conducive to technological leadership...

We analyze the economic impact of the accounting treatment of exploration expenditures in three different accounting regimes: aggregate disclosure, disaggregated disclosure, and a voluntary choice. The disclosure of information regarding the outcome of exploration can be used by competitors in...
