This assumption could be modified, allowing myopic DMs to ascertain the superior quality of the products the signaling firm offers when retrieving information from the corresponding market. Clearly, this modification would foster the signaling incentives of firms. However, it also implies that firms would prefer to deal with myopic DMs when signaling since they would face a threshold value of C – increasing the acceptance probability of their products relative to the B value defined by perfect foresight DMs –. Thus, preserving consistency implies that myopic DMs either do not observe or remain unaffected by the features on which technological improvements are introduced when retrieving information.</p><p id="para0114" class="elsevierStylePara elsevierViewall">On the other hand, when both firms issue signals and a signaling duopoly is defined, we will assume that both types of DMs acknowledge this fact and update the distribution of the second characteristic accordingly when retrieving information. Once all firms introduce a technological improvement within the market, the technology becomes standardized, and all DMs behave according to the updated distribution of characteristics. The model is designed to emphasize the risks the signaling firms face when issuing unilaterally, together with the resulting monopolistic gains. We could assume that both types of DMs prevail within the duopolistic signaling market, driving the expected revenues of the firms accordingly.

This latter requirement follows from the stricter evaluation constraint imposed on non-signaling firms within the SPE environment, requiring them to provide DMs with a value of the first characteristic higher than A, while in the pre-commitment and GI subgame perfect equilibria improvements were defined with respect to threshold C.</p></span></span><span id="sec0022" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cesectitle0026">Conclusion and extensions</span><p id="para0179" class="elsevierStylePara elsevierViewall">The current paper has presented an equilibrium model of [rational] demand for technology and strategic supply that verifies formally the economic intuition developed by <a class="elsevierStyleCrossRef" href="#bib0045">Malerba et al. (2003</a>, <a class="elsevierStyleCrossRef" href="#bib0046">2007</a>) and relates it to the results obtained by the operations research literature (<a class="elsevierStyleCrossRef" href="#bib0031">Jensen, 1988</a>; <a class="elsevierStyleCrossRef" href="#bib0013">Cho & McCardle, 2009</a>; <a class="elsevierStyleCrossRef" href="#bib0066">Ulu & Smith, 2009</a>). We have demonstrated how, after observing a positive credible signal, perfect foresight DMs are more willing to start searching for a product in the corresponding signaled market. However, perfect foresight triggers a slow-down in the adoption of the technology becoming available with respect to myopia. Even when considering consumption inertia and IDs, the realization of X1 required by perfect foresight DMs from the unsignaled market is quite higher than the one required by myopic DMs.</p><p id="para0180" class="elsevierStylePara elsevierViewall">Binary comparisons are common in most decision problems dealing with multiple criteria. In this regard, the formal structure introduced in the paper is sufficiently malleable to incorporate a third firm into the analysis. In this case, we should consider an additional set of potential realizations per characteristic – describing the products of the third competitor – and expand the expected utilities and transition matrices accordingly. The strategic framework would become substantially more complex while allowing for additional interactions among firms. Intuition regarding the effects derived from incorporating a third alternative to the analysis can be found in <a class="elsevierStyleCrossRef" href="#bib0020">Di Caprio et al. (2016)</a>, together with the corresponding formal analyses.</p><p id="para0181" class="elsevierStylePara elsevierViewall">The current analysis of technological demand complements the evolutionary branch of the literature that focuses on processes breaking out of an existing technological trajectory (<a class="elsevierStyleCrossRef" href="#bib0022">Dolfsma & Leydesdorff, 2009</a>; <a class="elsevierStyleCrossRef" href="#bib0053">Roy, 2018</a>; <a class="elsevierStyleCrossRef" href="#bib0033">Kanger et al., 2019</a>). The resulting policy implications range from the creation of programs to educate consumers on recent technological developments to the actual acquisition of technology by public institutions. For instance, it seems natural to assume that higher levels of experience and technical education are coupled with a higher tendency to experiment with novel products. In this regard, the capacity of DMs to observe and assimilate signals may also be determined by their experience as users and their level of technological education. Thus, the existence of relatively less educated, i.e., myopic, DMs exhibiting a higher degree of risk-aversion increases the probability of suboptimal locking-in events. As a result, myopic DMs should be considered when analyzing the pervasiveness of inferior products supplied by local monopolies within technologically underdeveloped countries and the inability of the latter to induce a sufficient pull in demand to trigger the introduction of further innovations.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:3 [

Market demand is built on conventional features defining the behavior of decision-makers (DMs), who are required to acquire information sequentially about the characteristics describing the products. Firms may signal the introduction of TSPs, though only sufficiently experimental DMs update their beliefs when selecting a product from a firm. That is, technological habits and inertia condition the incentives of DMs to acquire information and select potential products within a market. In particular, the choices made by the DMs will be determined by their capacity to assimilate signals describing the introduction of TSPs and their attitude towards risk.
