New Services
Huang et Al 2004
Research Question
RQ: In a crowdsourcing idea platform, what are the individual contribution dynamics?
Findings
-
This leads to initial over-crowding, followed by thinning out as individuals learn, and leads to efficiency.
Learning about idea potential is fast, but about cost is slow
-
Methodology
-
-
First, some visual analysis shows #ideas generated by individual decreases over time, implementation rates increase over time, votes per idea increases
Utility from idea = Ci (cost to post idea) + Ri (500 points) + diDit (Dij is Dis-incentive from idea not implemented in 12 weeks, and di is heterogenous individual cost) + THETAij (Utility from idea implemented) + e
Average cost of project is calculated as an update to prior belief's about cost through a Bayesian rule.
-
Background
-
They infer costs from Dell's ideastorm publicizing their implementation plans, in conjunction to votes.

Asvanund et Al 2004
Research Question
-
We know positive externalities exist. However, the negative externalities include consumption of scarce network resource, and free-riding.
Findings
With network size, users contribute additional value at a decreasing rate. Users impose costs on the network at an increasing rate. Users tend to contribute less resources.
At some point, costs of marginal user will be greater than benefits from him.
Methodology
Measures
Login congestion, Query Congestion, Song Availability (binary), song replication,

-
Findings
-
RD - big time. IT - not significant in 1987-1992, significant 1993-1997
-
Methodology
-
-
Controls = firm size, time, industry
Correct for: inflation in patents, truncation in accumulated citations for a given patent vintage

Research Question
-
Hypothesis Reasoning
-
Variety Creation
Through improved concept development, product design and Project Management
Variety Implementation
Through flexible manufacturing, supply chain coordination and portfolio management.
-
Methodology
Measures and Controls
TM_Holding: T0: TM Applied for. 5 years later: TM renewed or not. Do a survival analysis to find number of TM's held each year, and the length of TM holding by year. And TM_Applications
-
-
Econometric Controls: PSAR1, HE, firm fixed effects
-
IV
The Problem
Firm specific shocks like high demand could be causing both. OR Simultaneity - Greater product variety may be causing greater IT
Solution
Flexibility of IT infrastructure: newness of IT, capital age. Argument: These capture the firm's idiosyncratic ability to respond in the need for IT
Findings: IT increases TM applications and holdings, but reduces survival
